DEFINITION OF TERMS Franchisor: A franchisor is an entity that manages a brand and oversees the administration of services by healthcare providers operating under that brand. Franchisee: A franchisee is a private health facility that agrees to operate under a brand offered by a franchisor hence forming a franchise network. Franchisee Network: A franchise network is a collection of franchisees that have agreed to offer a set of services under a franchisor brand. Social Franchise: A social franchise is a network of private-sector health care providers that have agreed to offer a set of services under a common franchise brand with the aim of achieving social benefits. Short-term Family Planning Method: These are family planning methods whose period of service are less or equal to 1 year. Long-term Family Planning Method: These are FP whose period of service is more than 1 year. Depo-provera: This is a short-term FP method that may prevent conception for up to three months. Intrauterine Contraceptive Device: This is a long-term FP method that may prevent conception for up to twelve years. Norplant’s Contraceptive Implants: This is a long-term FP method that may prevent conception for up to five years. ABSTRACT The Kenyan private health sector is one of the most developed in Sub-Saharan Africa and is highly critical in healthcare delivery. It is often the first point of contact of 47 percent of the first quintile of income earners when they fall sick and 33 percent of women seek family planning services in this sector. Despite private sector ability to provide greater choices for customers, in several parts of Kenya, the cost of health services is a great impediment to service utilization. The concept of social franchising attempts to increase access to services in the private sector through various strategies such as capacity building of healthcare service providers, lowering cost of treatments by provision use of vouchers or supply of subsidized medical supplies and demand creation. However, there is scant literature on the impact of social franchising on healthcare expenditure within private healthcare facilities in Embu County, Kenya. This study investigated how social franchising has affected the consumer expenditure on private healthcare services namely family planning and children treatment services. The family planning methods included three-month short term family planning method Depo-Provera and long term family planning methods IUCD and Norplant’s implants which are supported by social franchisors. The study used a cross- section descriptive study design and conducted a cluster sampling in communities near franchised and non-franchised private health clinics in Embu County. The study used a total of 215 responses analyzed with STATA 14. Descriptive statistics used in this study include mean, median, and frequencies and inferential statistics include binary logistic regression with marginal effects and propensity score matching to determine the impact of social franchising on healthcare expenditure. The results reveal that expenditure on children's illnesses treatments and that of short-term family planning services were not statistically different between franchised and non-franchised health facilities. The study however found that there is a huge variance on the expenditure of long-term family planning services between the two classes of clinics with women in franchised health facilities paying on average $4.5 less due to provision of vouchers by the franchisors. The study recommends expansion of social franchisors network to reach bottom of economic pyramid and scaling up the capacity building of medical workers through training to improve quality of services provided. CHAPTER ONE INTRODUCTION 1.1 Background of the Study Universal Health Coverage (UHC) is a priority policy agenda in the Sustainable Development Goals (SDG). The SDG3 “good health and well-being”, where UHC falls, is driven by the need for improved access to quality health services for all through safe, effective, quality and affordable health care (WHO, 2016). Healthcare services should be based on the need and not the ability to pay, however, in developing countries it is the ability to pay that determines access to quality health care services especially the services provided by the private sector (WHO, 2010). Several attempts have been made to improve access healthcare services in developing countries which includes pooling or mandatory contributions to social health insurance (National Hospital Insurance Fund [NHIF] for Kenyans) among formal employees and increasing national budget allocation on health (MoH, 2013). The WHO (2010) regards mandatory prepayment as the most efficient and equitable financing system for UHC. However, majority of people in the bottom of economic pyramid are still not covered by any health insurance pushing both public and private sectors to other interventions to improve access to quality healthcare services. In response to SDG 3, the Kenyan government has introduced several interventions to protect its people from catastrophic and impoverishing healthcare costs and to steer the country toward UHC. Such interventions are informed by the fact that nearly half of Kenyans are not covered by a health insurance such as NHIF and about 1.5 million Kenyans are pushed into poverty each year (impoverished) as a result of out of pocket payments for health care (MoH, 2017). The national government budget allocation on healthcare of 7 percent on average is below the Abuja Declaration of 15 percent which causes public health sector have inadequate resources to serve the public pushing more people into the private sector. To support the healthcare system social franchisors intervention includes capacity building private sector service providers, directly supplying subsidized medical supplies to reduce the cost burden of medical products and services and the use of vouchers as a method of demand creation especially amongst the poor in the society (PSK, 2017). The concept of social franchising adapts a commercial franchising model to achieve social benefits rather than financial goals (Montagu, 2002). Franchisees are then able to enjoy professional training and consultancy, receive subsidized medical supplies and equipment, and often times franchisors advertise franchise brand for the advantage of the franchisees (Montagu, 2002). These increase brand visibility and is intended to increase a wider range of services utilization within the franchise network. Social franchising was first introduced in the 1990s by the United States Agency for International Development (USAID) in the Philippines and Mexico with the aim of expanding markets for clinical family planning services (Montagu, 2002). According to PSI (2017), social franchising is currently operating in over 40 countries including Kenya. Franchising is geared toward service delivery, franchisees are able to enjoy economies of scale in purchasing and advertising as a network rather than individuals and hence possibly enjoy lower supply prices. It has also has been found effective in increasing the scope of services among franchisees and increase access to quality services (Montagu, 2002). However medical providers may be required to pay franchise fees, maintain specified levels of service quality and meet sales quotas which positively increases the uptake of services among franchisees. 1.1.1 Kenya Health System The health system in Kenya can be classified into the public (46 percent), private sector (40 percent), and faith-based organizations/non-governmental organizations (14 percent) (MOH, 2019). The private sector in Kenya can be further divided into franchised and non-franchised private health facilities though there is dearth of literature difference in terms of scope services provision, health expenditure, and outcomes in the society. The government budget allocation to the health sector which is 7.1 percent is lower than 15 percent budget allocation recommended in the Abuja declaration (MoH, 2017) which causes public health system have inadequate resources pushing people to the private health system. According to USAID (2014) due to unmet demand by the public sector, 37 percent of health spending occurs in private facilities, 47 percent of Kenya uses the private facility when they fall sick and 33 percent of women obtain family planning services in the private sector. Also, 68 percent of private-sector patients use out of pocket payments (MOH, 2015). This shows private healthcare providers are equally important in Kenya especially in the provision of regular services that related to women and children. Figure 1.1 shows proportion of people health expenditure in Kenya by type of facility Development partners26% Public sector34% Private sector40% Figure 1.1: Kenya Total Healthcare Expenditure. Source: Ministry of Health 2017 Figure 1.1 shows that 40 percent of Kenyans health expenditure occurs in private, 34 percent occurs in public, and 26 percent occurs in development partner’s health facilities. According to Wanjala (2019) due to high cost of healthcare 12.7 percent of Kenyans do not seek health services when they fall sick and 2.6 million (6.2 percent) of households risk being impoverished due to out of pocket payment for health services. Figure 1.2 show that family planning services uptake between private, public sector, and shops, mobile clinics, community health workers (CHW) and friends. 74.5 39.6 63.4 62.7 78.2 23.7 21.4 57 33.6 36.4 18.2 19.4 0.6 2.9 2.8 0.6 3.5 48.3 0 20 40 60 80 Femalesterilisation Pill IUD Injectables Implants Malecondoms percent Public sector Private medical sector shop, mobile clinic, chw, friend Figure 1.2: Family Planning Methods by Service Provider. Source KNBS (2014) In Figure 1.2 the private sector cannot be overlooked in the provision of important health services such as family planning services in Kenya. While 64.3 percent of IUD consumers seek services in the public sector, 34.5 percent seek these services in the private sector out of which 36.4 percent seek injectable services and 18.2 percent seek implants services. Also, the majority of pills services (57 percent) and male condoms are provided by the private sector.

Source: MOH (2017). Despite the increased budget for family planning services, Figure 1.3 shows that the funding gap is widening which makes the interventions offered by the private sector very important. However, private sector whose optimization problem is to maximize profits may exclude some clients hence need for interventions within the private sector. Social franchising is one of such interventions whose impact is not adequately assessed in Kenya. The Embu County health system comprises of 54 percent public and 46 private health facilities. Data from Ministry of Health show there are 20 nurses, 4 doctors and 6 clinical officers per 10,000 people which is below recommendation by the World Health Organization for the achievement of the Universal Health Coverage (MoH, 2020). The county has a fertility rate of 3.1 children per woman, 67 percent of married women use contraceptives, 81 percent of the births are attended by a skilled health worker and 86 percent of children 12-23 months are fully vaccinated. Children illnesses are still a challenge with only 56 percent of women having attended more than four antenatal clinics, 27 percent of children under five are stunted, and malaria test positivity rate of 57 percent is higher than national average (KNBS, 2019). The county is still faced by health sector budget deficit with County Government providing only half of the budget needed to completely satisfy FP and children services. This means the private sector is very important in the provision of health services even though there is a dearth of literature on the impact on intervention made in the private sectors on heath expenditure in Embu County. Figure 1.4 below shows that Embu County has family planning deficit of 68 - 72 million 138.78 144.09 142.46 142.39 70.28 70.28 70.28 70.28 68.50 73.81 72.17 72.10 0 20 40 60 80 100 120 140 160 2017 2018 2019 2020 Million Ksh Family planning required budget Family planning available budget Family planning budget deficit Figure 1.4: Family Planning Budget Deficit Embu County. Source: County Government of Embu Integrated Development Plan 2018-2022 Though Embu County have attained modern contraceptives uptake of 67 per cent, the uptake has reduced from 74 per cent in the past eight years (KNBS, 2019). Figure 1.4 shows that the progress in attaining family planning by the county government is constrained by resources. To strengthen the uptake of maternal and children services, social franchisors have made interventions in Kenya and Embu County alike. The main interventions of franchisors in Kenya healthcare system includes capacity building private healthcare providers to deliver maternal and child health services at an affordable costs (ASFH, 2018). However, there is inadequate empirical evidence of the impact of social franchisors on people heath expenditure on the services being supported by the franchisors. Figure 1.5 shows various indicators on children health in Embu County which include percentage of children stunting, underweight and malaria positivity rates. 26.8 24.5 11.1 57 26 20.4 11 41 0 10 20 30 40 50 60 Children stunting Still birth rate Underweightchildren Malaria testpositivity rate Percent (%) Embu County National Average Figure 1.5: Indicators of Children Health for Embu County Compared to National Average Source: Ministry of Health Kenya Figure 1.5 show that Embu County needs several interventions to strengthen children health and improve responses in the healthcare system. The available data from the Ministry of Health show that the average number of children stunting is 26.8 percent higher than national average of 26 percent which means higher proportion of children in Embu County than national face impaired growth and development as a result of poor maternal health, nutrition and repeated infection. These are closely affected by inability to access healthcare services or bigger family size than the parents can afford to support financially. A still birth rate of 24.5 percent higher than national average 20.4 percent reveal the county is still facing maternal health issue and malaria positivity rates of 57 percent higher than national average of 41 percent show that both public and private healthcare system is important to handle children illnesses. However, expenditure on health could be a challenge to services utilization especially in private sector. 1.1.2 Private Healthcare Expenditure in Kenya Despite interventions in the health sector in Kenya to lower out of pocket healthcare expenditure several issues still push people to private sectors. A study by World Bank shows out-of-pocket expenditure as percent of total health expenditure is more than 50 percent higher than Sub-Saharan Africa average of 29.8 percent. It is also estimated that 6.2 percent of households experience catastrophic health expenditure. Figure 1.6 shows catastrophic health expenditure in Kenya by wealth quintile. Catastrophic health expenditure is expressed as a household expenditure on health which is more than 40 percent or more of a household’s non-subsistence income 9.9 5.6 4.2 2.7 1.2 5.7 3.2 0 4 8 12 Poorest Second Middle Fourth Richest Rural Urban Consumption quintile Residence Percent Figure 1.6: Catastrophic Health Expenditure in Kenya by Wealth Quintile Source: Kimani and Maina. (2015). Catastrophic Health Expenditures and Impoverishment in Kenya. Figure 1.6 show that the poorest and rural people are the most exposed to catastrophic health expenditure in Kenya yet this category is living below $1.8 Usd/day. The financing of healthcare budget in Kenya is contributed by 28 percent household out-of- pocket payments and 60 percent is on curative with only 20 percent being preventative (MoH, 2019). The fact that public healthcare services in level one and two facilities which are nearly free suffers several hurdles in delivery of quality healthcare, many people are pushed to private facilities which adds a premium due to their optimization problem.

World Bank Public Expenditure Tracking Survey (PETS) and Service Delivery Indicators (SDI) revealed several sources of inefficiency that undermine the effectiveness and quality of the public health care in Kenya that are likely to push people to non-public health facilities. These include: drugs availability, equipment availability, diagnostic accuracy, drugs availability, infrastructure availability absence from the facility and shortage of equipment and hospital infrastructure. 1.1.3 Social Franchising in Kenya The popularity of social franchising is growing in Kenya. Currently, there are six social franchising brands namely Population Services Kenya (PSK) under a brand Tunza, Marie Stopes Kenya (MSK) under a brand Amua, Gold Star Kenya (GSK), Kisumu Medical and Education Trust (KMET) under Huduma Poa brand and Sustainable Healthcare Foundation under CFW brand (Association of Social Franchising for Health, 2018). These social franchisors partner with private health facilities to provide selected services under respective brands, most of which include the provision of family planning services and integrated management of childhood illness with a core mandate of increasing access, quality, improve equity, and enhance the cost- effectiveness of healthcare services (ASFH, 2018). According to Chakraborty & Mbondo (2016), social franchisors in Kenya are supposed to maximize family planning uptake, offer training to service providers, and oversees activities of franchisees. In Kenya, there are 6,032 private health facilities out of which 15 percent (900) facilities are in any of the five social franchisors but MSK and PSK form 85 percent of all franchised facilities in Kenya (ASFH, 2018). The intervention of social franchising in Kenya is to improve access to quality health services by ensuring service delivery points which are private health facilities adhere to specific quality standards. PSK and MSK support private facilities improve quality services through step wise quality improvement process which leads to certification. The process also include training service and linkages to affordable loans to help providers improve/expand their facilities. Social franchising is an intervention to serve the poor people in the society. Social franchisors uses interventions such as vouchers to reach the poorest in the society access quality services provided by the franchisors. Though such intervention are considered costly they have been found effective in increasing access to maternal health and children services in countries such as Pakistan and Uganda (Ali et al, 2019; Hastings and Sarker, 2019). PSK social franchising model has entered into contractual agreements with 420 private health providers to deliver quality and affordable target services to the customers with special focus on family planning and integrated management of children illness (PSK, 2020); MSK social franchising model has entered into contractual agreements with 400 private health providers to improve access to quality reproductive healthcare in private health facilities at a very affordable price (MSK, 2020); KMET is working with private sector to expand and promote access to affordable, quality reproductive health care to communities in need of such services, with an emphasis on maternal and newborn health and adolescent reproductive health services (KMET, 2020); Gold Star Kenya is also contributing to improving the management of priority health conditions including maternal, neonatal, child health and adolescent health, family planning, sexual and reproductive health services (GSK, 2020); and CFW is working with the private sector to improve access to essential drugs, basic healthcare, and prevention services for children and families through economies of scale (SHF, 2020). Despite such interventions by social franchisor, there is dearth of literature on the impact of social franchisors in Kenya especially on increasing access through shifting consumer budget line. 1.2 Statement of the Problem Good health is considered an investment and consumption good. Investing in the health of women and children such as family planning and integrated management of children illnesses improves the health of women and children increasing their productivity and learning outcomes. Women who invest in family planning have the right household size for quality health of the family, and may indirectly promote savings as it helps to avert costs associated with unintended pregnancies. On the other hand children with good health have a better learning outcomes. A dollar spent on family planning saves nearly 4.5 dollars in direct healthcare costs (HPP, USAID, & MSI, 2014). Health as a consumption good helps consumers enjoy utility derived from good health and capacity to participate in the labour force or in school. However, a major deterrent to the consumption of healthcare services is the health expenditure incurred when purchasing this good and services. With more than one choices available, consumers will select services providers who maximize their utility at a minimum budget. In Embu County, the contraceptive prevalence rate is on downtrend having reduced from 74 per cent in 2012 to 68 percent in 2018 with unmet demand of 24 percent. The county stunted children is 26.8 percent and underweight children is 11.1 per cent higher than national average of 26 percent and 11 percent respectively. Though women who access skilled birth attendant is above national average, still birth rate of 24.5 per cent is still higher than national average of 20.4 percent. Such statistics reveal the county is still facing challenges in access to maternal and children health services. Generally, public health facilities in Kenya which has the lowest cost has a challenge of frequent stock-outs [almost 57 percent] (WHO, 2012) pushing customers into private health facilities where clients pay a higher premium to receive the services. Embu County is among the poorest counties in Kenya with its share of Gross County Product (GCP) to Gross Domestic Product (GDP) having reduced from 1.5 percent to 1.3 percent between 2015 and 2017. Its GCP per capita is the worst growing below 1.5 per cent compared to country average 2.8 per cent. There has been attempts to improve access to healthcare offered by private sector through public-private partnerships and social franchising model. The aim of social franchising in Kenya is to improve access to quality healthcare services, improve equity and to enhance the cost-effectiveness of healthcare service. Social franchisors also support private health facilities through supply of subsidized medical products to lower private healthcare cost and improve access. Despite the presence of social franchisors in Embu County such as Maries Stopes Kenya, Population Services Kenya, and Sustainable Healthcare Foundation, there was dearth of empirical literature on their impact especially on health expenditure which is a major barrier to access and affordability to the services provided. Studies evaluating the impact of social franchising had focused on quality, equity, and customer increase (Chakraborty et al., 2016) with narrow focus on health expenditure or cost which influences demand for these services. Studies from other countries had shown mixed results on the impact of social franchising. These studies had also neglected a very important economic concept in their analyses that consumer expenditure is dependent on their budget. The present study contributed to the discussion by investigating the impact of social franchising on healthcare expenditure within private healthcare facilities in Kenya. The study employed Propensity Score matching evaluation model to estimate whether social franchising shifts the consumer budget line outward or inward hence influencing demand for such services within private facilities. 1.3 Objectives of the Study 1.3.1 Main Objective The main objective of this study was to investigate the impact of social franchising on healthcare expenditure within private health facilities in Embu County Kenya. 1.3.2 Research Questions i.

To establish the impact of social franchising on children's healthcare services expenditure within private facilities in Embu County ii. To establish the impact of social franchising on short-term family planning services expenditure within private facilities in Embu County iii. To establish the impact of social franchising on long term family planning services expenditure within private facilities in Embu County. 1.4 Significance of the Study Maternal and child health is important in enhancing the health of women and children. The purpose of this study was to establish whether social franchising affects the health expenditure of children services and family planning in the private sector. The findings of this study are very useful to policymakers as they may understand the impact social franchising has on the cost of services since healthcare-seeking behavior is affected by factors such as affordability. The private healthcare providers find this report useful in their decision to join a social franchise network; donors who support social franchisors also find this report useful to understand extent to which social franchising model has generated cost-effective business model in the health sector, and family planning consumers may find this report useful in decision making on where to seek family planning services. Health policy makers may also find this report useful in understanding the role of social franchising in health sector and their effect on health expenditure. The findings of this study are also helpful in contributing to the body of existing literature on the impact of social franchising on healthcare expenditure within private facilities. 1.5 Scope of the Study This study investigated the impact of social franchising on healthcare expenditure within private facilities in Embu county Kenya. The study focused on the impact of social franchising on expenditure on children healthcare services and various FP services such as short term FP method (Depo-Provera) and longer-term FP methods (implants and IUCD). Data was collected from people seeking services in PSK and CFW franchisee for treated facilities and those who sought services in other private which do not belong to any social franchise network. 1.6 Organization of the Study Chapter one presented the background of the study, chapter two reviews both theoretical and empirical literature while chapter three presents research methodology. Presentation and discussion of empirical results is offered in chapter four. Chapter five summarizes the paper, concludes it and gives policy recommendations. CHAPTER TWO LITERATURE REVIEW 2.1 Introduction This chapter reviews theoretical literature, empirical literature, and provides an overview of the literature. The overview of the literature summarizes critical findings from the theories reviewed and empirical literature in order to draw the research gap. 2.2 Theoretical Literature This section presents theories that guided the study. The study has adopted the principal agent theory and consumer theory as a theoretical framework. 2.2.1 Principal-Agent Theory The principal-agent theory was proposed and developed by Ross (1974) and Mitnick (1974). The theory is normally referred to as a principal-agent theory, where principal refers to an individual, an institution or an economic agent, while agent refers to the second party working on behalf of the principal. The theory assumes there is a contractual relationship between the principal and the agent where the principal delegates some responsibilities to the agent. The agent behavior directly affects the principal, even though a major challenge in the relationship is information asymmetry, where the principal may lose control over the intentions of the agent (Volery & Hackl, 2009). In this scenario, an agent may deviate from the agreement because they are self- interested and engaged in opportunistic behaviors. There is two main application of the principal-agent theory in this study. First social franchisors are principal and franchisees are agents. The social franchisors may have an intention to increase communities’ access to quality services offered in private health facilities located within the communities and therefore introduce voucher programs to the community members, supply lower priced products to the healthcare providers or provide price controls to the clinics to improve affordability. However, as pointed out in the theory, the principle doesn’t have full control of the intentions of the franchisees who may engage in opportunistic behavior to maximize their profits. In the latter, the cost of healthcare services will be the same in both treated and untreated facilities despite the interventions. The second application of this theory is individual seeking services in private health facilities as principals and private facilities health providers as agents. A customer (principal) will procure the services from a healthcare provider (agent) with the aim of maximizing their satisfaction subject to their budget constraint. Under consumer theory consumers will chose facilities that maximize their utility with minimum budget yet the agent may violate consumer expectations and charge equal or above market rates despite the interventions provided to the social franchisors. This study applies both concepts to determine whether customers seeking services in franchised facilities pay significantly less as intended by the franchisors and receive quality services. However, the customer’s choice of agent (healthcare facility) has an underlying economic theory of consumer demand. The theory posits cost paid by the consumer as a function of their income and quantity demanded (Varian, 2010). 2.2.2 Consumer Theory Consumer theory is an economic theory that studies how individuals make decisions that relate to purchasing goods and services to satisfy their needs given a budget constraint. It is concerned with how a rational consumer would make their consumption decisions to maximize their welfare. The theory assumes a utility is generated when a consumer purchases goods and services that satisfy their needs and wants and that they have a budget constraint. The definition of the utility function is a representation of the preferences of a consumer. The consumer utility function for consuming two units of goods can be represented as 𝑈(𝑍)=𝑈(𝑍1𝑍2). The theory also assumes a consumer has a fixed amount of money to spend (M) and each unit of good purchased has some costs attached to them referred to as price (P) which is expenditure on goods 𝑍1and 𝑍2. Therefore a consumer budget constraint for their set of choices can be presented mathematically as 𝑃1𝑍1+𝑃2𝑍2≤𝑀. We can therefore define consumer problem as 𝑀𝑎𝑥 𝑈 (𝑍)=𝑈(𝑍1𝑍2) 𝑠𝑡 𝑃1𝑍1+𝑃2𝑍2≤𝑀 ………………………………………………………….2.1 Where 𝑈=𝑈(𝑍1𝑍2) is the utility derived by consumption of healthcare services 𝑍1and other product and services 𝑍2, 𝑃1 is the expenditure on healthcare services; 𝑃2 is the consumer expenditure on other products and services and M is the individual income. Forming a Lagrangian function, solving an optimization process and transforming normal demand function into inverse demand function we find the healthcare expenditure as a function of healthcare services sought and individual income/ability to meet the cost such that 𝑃1=𝐹(𝑀,𝑍1)………………………………………………………………………2.2 In summary, any program that would affect the cost of family planning directly affects consumer welfare by shifting consumer’s budget line outward or inward. An increase in the price of good and services reduces available money stock shifting consumer’s budget line inward and reduction shifts consumer budget line inward leaving more money to consumer other goods and services. If the interventions of franchising are cost effective then consumer. 2.3 Empirical Literature 2.3.1 Impact of Cost of Health Services on Patient Affordability and Access Abiye, Tesfaye, and Hawaze (2013) studied barriers to access to essential medical services in Ethiopia public health sector. Data was collected from patients seeking medical treatment. Comparing prices of essential medical supplies between public facilities, pharmacies, and the private sectors, the study revealed the private sector was 32 percent higher than the public sector, and these services are not affordable. The public hospitals had a regular stock-out problem. Carasso et al. (2009) study had also found there exists frequent drug shortages in the public sector and unaffordable prices deter patients from seeking services in the private sector. Programs to make private healthcare services affordable were significant in increasing access to services in several areas. Mhlanga and Suleman (2014) investigated “prices, availability, and affordability of medicines” in urban areas of Swaziland. Data was collected among private health facilities and public health facilities and analyzed descriptively. The study found medical commodities prices in the public sector were very competitive while the patient’s prices were very expensive in the private sector. The study concluded a lack of affordability of essential medical commodities is associated with their high prices since in Africa most healthcare seekers lack social insurance systems and therefore use out of pocket payment methods. Programs and policies to lower prices would help lower prices. It was also found high prices limit demand in the private sector where price markup was 31 – 53 percent above prices in the public sector. Ewen et al. (2017) studied “prices and availability of locally produced and imported medicines in Tanzania and Ethiopia” using data collected from the government procurement department and survey from patients. The study did not establish any price differences between locally produced and imported medical commodities in Tanzania. However, in Ethiopia, prices charged to patients were lower for imports in the public sector and more for imported commodities traded in the private sector. Earlier studies by Mackintosh and Mujinja (2008) comparing medical commodities prices between Tanzania, India, and Kenya found no significant patient price differences between locally produced and imported medicines. In countries such as Malaysia, Bangladesh and Vietnam prices of locally produced brands are lower compared to import ones (Ewen et al., 2017). These studies also found that higher prices of medical commodities limited their affordability and access. According to Collins et al. (2017) to improve access and affordability of medical services, there is a need to prioritize patient access and affordability in both government and non-government programs, enhance efficient markets where there is price competition, and improve the availability of information. The policy paper also points out that generic drugs are less expensive than patent drugs and purchasing medical commodities through an agency lowers the prices of medical commodities. This could mean, social franchising could be a better model of making family planning services affordable in the private sector. 2.3.2 Impact Social Franchising on Family Planning and Children Services Patouillard et al. (2007) conducted a systematic review of the literature seeking to establish whether “working with the private for-profit sector improve utilization of quality health services by the poor.” Results from 52 empirical studies found working with the private sector to improve the utilization of healthcare services were successful among poor countries as it increased utilization. However, the utilization was mainly attributed to the use of provided vouchers among poor individuals from Zambia and Nicaragua. The use of vouchers reduced the price of services among franchised health facilities by 17 percent. The study found the use of vouchers as a strategy to lower prices, use of cash transfer and provider subsidies remain unexplored and more studies require to be conducted to determine whether the use of price strategies would improve access to family planning services among private health’s facilities. Shah, Wang, and Bishai (2011) compared family planning services provided by the private sector to government and NGO facilities in Ethiopia and Pakistan across cost, quality, and equity. Data were collected from independent private sector providers, NGO providers, government providers, and social franchises from private providers. Wilcoxon rank-sum tests were used to compare equal medians due to the problem of skewed data especially on the cost which was calculated in the form of currency. The results revealed higher clinical costs per client among franchised private health facilities in Ethiopia and not statistically different in Pakistan. Access to franchised private health facilities was lower in Ethiopia. However, the total quality of care was statistically significantly higher among private franchised clinics in both Ethiopia and Pakistan. Therefore, NGO facilities and Government facilities are the most efficient in serving most clients per dollar. To improve access among franchised health facilities, there is a need to lower prices either through vouchers, insurance or fee waiver programs. Huntington et al. (2012) studied factors influencing demand for a social franchise membership in Myanmar among physicians. A physician joins a franchise network for free and is required to adhere to price capitation specified by the franchisor on the various medical products. The physician enjoys signage, in-service training, receive medical products at highly subsidized prices and up to date information. The study found the impact of joining a franchise network was unclear even though there were increased client volumes. The surge in membership incomes was not only attributed to increased client volumes but also the fact that due to agency problems, franchised physicians are likely to charge higher prices to customers. Beyeler, York De La Cruz, and Montagu (2013) did a systematic review to “determine the impact of clinical social franchising on health services in low-and middle-income countries” the study covered countries such as Pakistan, Nepal and India. The use of a voucher system increased contraceptive use by 2.29 percent in Nepal and 23 percent in Pakistan. However, there was no statistically significant difference between demands for services in either franchised on non-franchised health facilities in Kenya. Azmat et al. (2014) studied the impact of social franchising on contraceptive use when completed by vouchers using a quasi-experimental study in rural Pakistan between 2009 and 2010. The target population involved married women within reproductive age living within franchised or non-franchised health facilities. The study established among franchised health facilities, LARCs customers were provided with vouchers that reduced the prices of family planning services significantly compared to non- franchised health facilities. The reduction of prices for LARCs customers increased demand by 28.5 percent while contraceptive prevalence increased by 19.6 percent. The study population if different from Kenya. Chakraborty et al. (2016) evaluated the impact of social franchising on family planning use in Kenya among Tunza franchised clinics. The study utilized a quasi-experimental study design where data was collected from Tunza franchised clinics catchment areas and compared to catchment areas where no franchised facility was present. The target population was women of reproductive age and were sampled using a systematic sampling technique. Binary multivariate logistic regression was used to estimate the marginal effects. The results showed that the presence of franchised health facilities did not attract new users of modern family planning methods and prices were not significantly different. The study, however, did not establish why there is no difference in the utilization of family planning services between franchised and non-franchised health facilities. Gold et al. (2017) studied “increasing access to family planning choices through public- sector social franchising in Mali” between 2012 and 2015 among franchised and non- franchised health facilities. The study analyzed data collected from MSI Mali Bluestar franchise networks that franchise health facilities to deliver affordable family planning services. The study found among franchised health facilities, prices were 13 times less compared to non-franchised facilities and the number of clients seeking LARC expanded four times. Therefore, lowering LARC service is likely to improve service utilization as rational customers seek pocket-friendly services. Bellows et al. (2017) studied how to improve contraceptive access for hard to reach populations in Uganda through a social franchising model. The study employed pricing strategies where prices were lowered using a voucher program. At the beginning of the program, only 18 percent of the women used LARCs and permanent methods (PMs) and unmet demand stood at 34 percent. After the implementation of the program, it was established lowering prices increased modern contraceptive prevalence by 8 percent. Therefore, lowering the cost through vouchers and social franchising is effective in expanding family planning access among private sector franchises. Also, lowering prices surged demand for LARCs and PMs. It was necessary to replicate such a study in Kenya to understand the extent to which social franchising has affected the pricing of private health facilities and therefore improved access to quality services provided by private health facilities in Kenya. Chakraborty, Montagu, Wanderi & Oduor (2019) investigated “who Serves the Poor? An Equity Analysis of Public and Private Providers of Family Planning and Child Health Services in Kenya” data was collected from social franchise, public, private for profit and faith based facilities. The findings of the study found that franchised health facilities serve the poorest than private for profit though their difference was not statistically significant. The impact of social franchisors was in family planning than in children illnesses but outperformed by public facilities. The study since social franchising targets services expansion to the poorest in the communities, the study did not employ treatment evaluation models such as propensity score matching or difference in difference to estimate the impact of social franchising on health expenditure which may have resulted to no significant differences in the mean amount paid by clients within private facilities. The present study used propensity score matching to estimate the cost differences. 2.4 Overview of the Literature The study has reviewed consumer theory and principal-agent theory where the latter demonstrated that the principal (franchisors) directly affects agent (franchisee) activities and the former which demonstrates that theoretically expenditure on health services is a function of consumer budget for such services. The study therefore utilized consumer theory as a theoretical foundation of the study but bearing in mind that social franchisors is a principal agent concept. Consumers being rational will chose lower priced services which means the effect of principal is reflected on the consumer behavior as long as they have all the information. Assuming both theory works well, then health expenditure will be lower for people seeking services in franchised facilities. The empirical literature studies on the impact of social franchising on healthcare expenditure show mixed results and therefore difficult to conclude the true impact of social franchising in the private healthcare expenditure especially through the price channel. Some of the studies reviewed for instance demonstrate social franchising had significant effect on price or utilization of healthcare services (Azmat et al., 2014; Gold et al., 2017; Patouillard et al., 2007; Bellows et al., 2017), others show there is no significant association between the two (Huntington et al., 2012; Chakraborty et al., 2016), and others reveals social franchising negatively affects the cost of services (Shah et al., 2011). The study filled this empirical gap by establishing the impact of social franchising on private healthcare expenditure in Kenya by strategically selecting the services which franchisors are interested in i.e. integrated management of children illness and family planning. This study employed an impact evaluation model propensity score matching (PSM) to determine the impact of social franchising on healthcare expenditure within private healthcare facilities in Kenya while controlling all the potential confounders. Such methodology was not previously employed in the available literature on the subject in Kenya. CHAPTER THREE RESEARCH METHODOLOGY 3.1 Introduction This chapter presents the research methodology employed to achieve the objectives of the study. It is organized as research design, theoretical framework, definition and measurement of variables, data types and sources, target population and sample size, sampling method, data collection, data analysis and diagnostic tests. 3.2 Research Design The study used a cross-sectional research design relying on both qualitative and quantitative data. A cross-sectional design was used because data were collected at a certain point in time to describe whether social franchising has an impact on the expenditure of services in private facilities. 3.3 Theoretical Framework This study was anchored on consumer theory where the expenditure on healthcare services is a function of services sought and consumer income bearing in mind that social franchising is a principal agent theory concept. i.e the interventions of social franchisors on the franchisee network is reflected on the consumer expenditure on health between franchised and non-franchised facilities. Healthcare is both an investment and a consumption good. As an investment good, families that have invested in reproductive health services such as family planning have more educated members, have reduced healthcare costs, women participate in the paid labour force and are therefore wealthier (WHO, 2015). The household derives utility from maternal and children's health from the consumption ceteris paribus. To acquire maternal and children health services, a household has a choice public, private for- profit, private franchised, mission, herbalists, chemist, or shops as service providers. Consumers are utility maximizers and given various healthcare providers they choose a provider who maximizes their utility with a minimum budget. The utility is therefore derived by consuming goods and services, and individuals have a steady preference displayed in a utility function ( 𝑈{𝑍}=𝑈(𝑍1𝑍2). Where Z1 is utility derived by consuming healthcare services and Z2 is the utility derived by consumption of other services. The benefit of consuming health services is good maternal and children's health while the high cost of health services is considered a disutility because it reduces the consumption of other goods and services. Since consumption of maternal and children health services improves women human capital but lowers budget allocation to other goods and services due to economic costs associated with the consumption of these services, individual will chose a health facility who maximizes the utility subject to budget constraint such that: 𝑀𝑎𝑥 𝑈 (𝑍)=𝑈(𝑍1𝑍2) 𝑠𝑡 𝑃1𝑍1+𝑃2𝑍2≤𝑀 ………………………….3.1 Where 𝑈=𝑈(𝑍1𝑍2) is the utility derived by consumption of health services 𝑍1and other product and services 𝑍2, 𝑃1 is the expenditure on health services; 𝑃2 is the expenditure on other products and services and M is the individual income. 𝐿=𝑍1𝑍2−ʎ(𝑃1𝑍1+𝑃2𝑍2−𝑀).......................................................3.2 The first order conditions for utility maximization is as follows 𝜕𝐿 𝜕𝑍1=𝑍2−ʎ 𝑃1 = 0................................................................3.3 𝜕𝐿 𝜕𝑍2=𝑍1−ʎ 𝑃2 = 0................................................................3.4 𝜕𝐿 𝜕ʎ =𝑃1𝑍1+𝑃2𝑍2−𝑀 = 0.......................................................3.5 From the first order conditions, healthcare demand function is derived as: 𝑍1= 𝑀 2𝑃1...............................................................…….........3.6 Equation 3.6 means demand for healthcare is a function of income M and the cost (𝑃1). The higher the cost the lower the demand for health. From this demand function, we can derive an inverse demand function to equate cost of healthcare as a function income and type services as below. 𝑃1= 𝑀 2𝑍1……………………………………………………………………………3.7 𝑃1=𝐹(𝑀,𝑍1)………………………………………………………………………3.8 Equation 3.8 simply equates the healthcare expenditure as a function of individual income (M) and services utilized (Z). However from empirical literature reviewed in this study, health expenditure does not only depend on income of customers and services utilized but also distance to the health facility (L), type of a facility (T) (Public, Private, Mission, chemist e.t.c.), personal factors such as education level (El) and marital status (Ms), whether the cost is paid by an insurance (Ins) or out of pocket, employment status of the individual (Ei), and employment status of spouse (Es). P=𝐹(𝑀,𝑍,𝐿,𝑇,𝐸𝑙,𝑀𝑠,𝐼𝑛𝑠,𝐸𝑖,𝐸𝑠)…………………………………………3.9 3.3.1 Measuring the Impact of Social Franchising on Healthcare Expenditure The study conducted propensity score matching (PSM) to establish the average treatment effects of the treated (ATET) of social franchising on the expenditure of healthcare services. The PSM was introduced by Rosenbaum and Rubin (1983) and further strengthened by Heckman (1997). They define propensity score as 𝑒(𝑍𝑖) for subjects i (i=1…N) as simply the conditional probability (ranges from 0 to 1) of being assigned to a particular treatment given a vector of observed covariates 𝑍𝑖 such that 𝑒(𝑍𝑖)=Pr(𝐹𝑖=1|𝑍𝑖)…………………………………………………………3.10 Where 𝐹𝑖=1 for members of social franchise (treatment) and 𝐹𝑖=0 for non-franchised (control). 𝑍𝑖 is a vector of observed covariates for 𝑖𝑡ℎ subject. The potential outcome (cost of services) we define as 𝑀𝑖𝑍𝑖 for each customer i, where i=1…N and N denote the total sample. Therefore the treatment effect of an individual i can therefore be presented as 𝜏𝑖=𝑃1𝑖−𝑃0𝑖…..…………………………………………………………..3.11 𝑃1𝑖 is the cost of health services sought if an individual (i) seeks services in a franchised clinics and 𝑃0𝑖 is the cost of health services if an individual (i) seeks services in non- franchised clinics. 0 represents a non-franchised and 1 represents to a franchised clinic. The potential problem arises because only one outcome is observed for each individual i and the unobserved forms a counterfactual outcome hence not possible to estimate for individuals in the treatment group. To overcome this problem one has to calculate the average treatment effects of the treated defined as 𝜏𝐴𝑇𝐸𝑇=𝐸(𝜏|𝐹=1)=𝐸[𝑃1|𝐹=1]−𝐸[𝑃0|𝐹=1]………………..3.12 The counterfactual mean 𝐸[𝑃0|𝐹=1] is not observed for the individuals seeking services in franchised clinic, therefore, requires to be substituted. The easiest method would be to use the mean outcome of the untreated 𝐸[𝑃0|𝐹=0] however this not a good idea since the same factors are likely to influence the decision to seek services in either franchised or non-franchised clinic. This means expenditure on health services may differ even when social franchising had not really taken place leading to selection bias. We can, therefore, represent as: 𝐸[𝑃1|𝐹=1−𝐸[𝑃0|𝐹=0]=𝜏𝐴𝑇𝐸𝑇+𝐸[𝑃0|𝐹=1]−𝐸[𝑃(0)|𝐹=0]……..3.13 Rearranging above we can see the selection bias on the RHS as below. 𝐸[𝑃1|𝐹=1−𝐸[𝑃0|𝐹=0]−𝜏𝐴𝑇𝐸𝑇=𝐸[𝑃0|𝐹=1]−𝐸[𝑃0|𝐹=0]……3.14 This means we can only estimate true parameter 𝜏𝐴𝑇𝐸𝑇 if the selection bias term on the RHS =0. The randomness can only be achieved through efficient matching discussed in model estimation. 𝐸[𝑃0|𝐹=1]−𝐸[𝑃0|𝐹=0]=0 Therefore average treatment effects of the treated (ATET) is presented in equation 3.14 below 𝐸[𝑃0|𝐹=1]−𝐸[𝑃0|𝐹=0]−𝜏𝐴𝑇𝐸𝑇=0 𝐸[𝑃1|𝐹=1]−𝐸[𝑃0|𝐹=0]=𝜏𝐴𝑇𝐸𝑇……………………………………………3.15 3.4 Model Estimation Model estimation using PSM took four step procedure (Cameron and Trivedi, 2005). The first stage is the selection of covariates to be included in the model should be related to seeking services in franchised clinics and the ability to pay the cost of services provided to minimize the bias. This study used covariates derived from the theoretical model and empirical literature. The second stage is the computation of the propensity scores which was done using binary logit where F=1 if a member of social franchise and F=0 if not a member. Hence the model estimated took the form of 𝑒𝑖=Pr(𝐹𝑖=1|𝑍𝑖)=𝐺(𝑍 ω) Where 0 chi2 0.000 Log likelihood = -111.56885 Pseudo R2 0.2078 Treatment Coef. Std. Err. z P>z [95% Conf.

The result from Hosmer and Lemeshow’s goodness-of-fit test also indicated that the model fits the date well [Hosmer-Lemeshow chi2 (8) = 12.98, p 0.1124]. Table 4.6 shows the description of the estimated propensity scores in the region of common support.

Table 4.6 shows the description of the estimated propensity scores in the region of common support. The results revealed the mean propensity score for the entire sample was 0.377 implying the average probability of seeking services in a treated clinic for all individuals was 37.7 percent. Table 4.7 displays the inferior block of propensity scores and the number of treated and control in each block.

The balancing property was satisfied. This means the covariates that determine treatment and non-treatments are similar and the propensity scores as similar as well. 4.4 Impact of Social Franchising on Children's Healthcare Services within Private Facilities in Embu County Table 4.8 estimates the impact of social franchising on children healthcare services expenditure using radius, nearest neighbor, and kernel matching techniques Table 4.8: Impact of Franchising on the Expenditure of Children Services Dependent Variable: Expenditure on children services N ATET Std Err t-value Matching Algorithm Franchised Non-Franchised Nearest neighbor 78 64 -86.17 90.80 -0.949 Radius matching with a radius of 0.01 58 120 -27.77 65.23 0.426 Kernel method 78 137 -54.68 60.255 -0.908 Source: Author’s estimation from the study data To achieve objective one which wanted to establish the impact of social franchising on children healthcare services expenditure within franchised and non-franchised health facilities in Embu County, the study estimated Equation 3.19. The study found that the expenditure on children services was Ksh 86.17, Ksh 27.77 and Ksh 54.68 per visit lower for those seeking services in franchised facilities when compared to others in nearest neighbor, radius and kernel method respectively but such difference is not statistically significant at 1 per cent, 5 per cent and 10 per cent significance levels. The results are similar to a study by Chakraborty et al. (2019) who found there were no significant differences in the amount paid between franchised and non-franchised private facilities on child health services in Kenya. 4.5 Impact of Social Franchising on the Expenditure of Short-term Family Planning Services within Private Facilities in Embu County In order to estimate the second objective, equation 3.20 was estimated and results presented in Table 4.9. Table 4.9: Impact of Franchising on the Expenditure of Short-term FP Services Dependent Variable: Expenditure on Depo-Provera N ATET Std Err t-value Matching Algorithm Franchised Non-Franchised Nearest neighbor with Replacement 78 24 -22.5 15.67 -1.436 Kernel matching 78 137 -19.6 16.086 -1.218 Source: Author’s estimation from the study data The study wanted to establish whether being members of a social franchise network lowers the expenditure on short term family planning services. The results from Nearest neighbor and Kernel matching indicate that the mean expenditure of these services are Ksh 22.5 and Ksh 19.6 lower in franchised facilities respectively but such difference is not statistically different from non-franchised facilities at 1 percent, 5 percent and 10 percent significance levels. These results are similar to the study by Chakraborty et al. (2019) and Azman et al. (2011) who found that franchising did not have a significant effect on the expenditure of these services. 4.6 Impact of Social Franchising on the Expenditure of Long-term Family Planning Services within Private Facilities in Embu County In order to estimate the third objective, equation 3.21 was estimated and results presented in Table 4.10. Table 4.10: Impact of Franchising on the Expenditure of Longer-term FP services Dependent Variable: Expenditure on Longer-term FP services N ATET Std Err t-value Matching Algorithm Franchised Non-Franchised Nearest neighbor with Replacement 78 59 -459.95 85.603 -5.373 Kernel method 78 137 -462.59 70.812 -6.533 Source: Author’s estimation from the study data The study wanted to establish whether being members of a social franchise network lowers the expenditure on long-term family planning services. A computed t-value of 5.573 and 6.533 corresponding to nearest neighbor and kernel method in matching estimation (Table 4.10) implies that the null hypothesis is rejected at 5% levels of significance. The study, therefore, concludes individuals seeking longer-term family planning services pay Ksh 459.95 – Ksh 462.59 less than those seeking services from non-franchised facilities. This big variation is attributed to zero expenditure reported by some women. Those who reported zero expenditure reported to have been issued with vouchers that were used to access the family planning services. These results are similar to Azmat et al. (2014) study that investigated the impact of social franchising on contraceptive use in rural Pakistan and found the use of vouchers reduced the cost of LARCs significantly in franchised health facilities. Patouillard et al. (2007), Bellows et al. (2017) study also found the use of vouchers reduced the price of services among franchised health facilities making them more affordable. Gold et al. (2017) study among MSI Mali Bluestar franchise networks also found that franchised health facilities deliver affordable family planning services increasing demand for LARCs. The results are however different from the ones by Shah et al. (2011) in Ethiopia and Pakistan who revealed higher clinical costs per client among franchised private health facilities in Ethiopia and not statistically different in Pakistan. Similar to previous studies (Ewen et al., 2017; Mackintosh et al., 2008; Ewen et al., 2017) higher prices of medical commodities limits affordability and access. To improve access and affordability of medical services, there is a need to prioritize patient access and affordability in health facilities, enhance efficient markets where there is price competition, and improve the availability of information. CHAPTER FIVE SUMMARY, CONCLUSION, AND POLICY IMPLICATIONS 5.1 Introduction This chapter presents a summary of the study findings, conclusion and implications of the study findings. The chapter also presents the areas of further research. 5.2 Summary The main purpose of this study was to establish the impact of social franchising private healthcare expenditure in Embu County. The specific objectives were to establish the impact of social franchising on children health services, the impact of social franchising on short-term family planning services, and the impact of social franchising on long- term family planning services. Social franchising meant a respondent has sought services in a franchised health facility such as Tunza (PSK) and Sustainable Healthcare Foundation under (CFW) which are the available social franchisors in Embu County. Non-franchised meant a respondent sought services in a clinic that is not a member of the two social franchise networks. The study was motivated by the fact healthcare is an important component of SDGs and government Big4 agendas in Kenya and the fact the expenditure of healthcare especially children services has an effect on access and therefore a direct effect on the children's mortalities. On the other hand, private health facilities are the first point of contact among many Kenyans and therefore often time provides the first response. In Embu County, the FP prevalence has reduced by 7 percent in the past three years, the government has a deficit on FP provision (50 percent) and the presence of social franchisors should increase prevalence. The available studies on the effect of social franchising on healthcare have focused on quality, equity, and customer increase. This study has introduced the concept of the expenditure on private healthcare on the discussion of the impact of social franchising. The study introduced the concept of expenditure due to the theoretical foundation, price influences demand for goods and services. Therefore, the key contribution of this study is the evaluation of the way social franchising affects the expenditure of private healthcare which previous researchers have not considered in their analysis in Kenya. The other key strength of this study is the ability to employ impact evaluation model PSM, unlike previous researchers who have primarily focused on binary choice models especially Logit, Chi-square test of association, ANOVA, while others relied on descriptive statistics. The use of PSM ensured comparison is only between similar units and therefore taken care of non-randomization. The method is superior as it eliminates selection bias and makes selection into the treatment group as good as random. The first objective was to establish the impact of social franchising on children healthcare services within private health services in Embu County. The study found among the significant factors in the choice of where to seek children healthcare services includes the education level of the guardian, perceived quality of services, cost and distance of the facility. The study used PSM to estimate the ATET of the expenditure of children's healthcare services. The ATET estimation revealed respondents seeking services in franchised facilities paid a similar amount with those seeking services in non-franchised health facilities. However, the changes by the franchised facility were slightly less. The second objective was to establish the impact of social franchising on short-term family planning services within private health services. The study used PSM to estimate the ATET the expenditure of short-term FP services. The ATET estimation revealed the expenditure on these services in franchised facilities were not significantly different from those seeking them in non-franchised health facilities. The third objective was to establish the impact of social franchising on long-term family planning services within private health services. The study used PSM to estimate the ATET of the expenditure of longer-term FP services. The ATET estimation revealed the expenditure of these services in franchised facilities were significantly lower than those seeking them in non-franchised health facilities. This means the social franchisor's main impact is in the long-term family planning services. These services were subsidized among franchised facilities to a point where some clients paid zero cost. This shifts consumer’s budget line outward increasing demand for other services thus improving household welfare. 5.3 Conclusion The findings of the study indicated the choice of health facility is pegged on perceived quality of services provided, the type of services sought with women whose primary motive was to seek family planning services twice likely visit franchised health facilities, cost consideration with such individuals having higher probability of seeking services in franchised health facilities and distance with those residing franchised facilities having higher probaility of seeking services in these facilities. These results imply private facilities need to consider quality and pricing to attract customers. The fact that these attributes were singled out by those seeking services in franchised facilities means a franchised health facilities are perceived to be of higher quality and of lower cost by customers. The findings revealed individuals seeking services in franchised health facilities paid less on longer-term family planning services relative to those seeking services in non- franchised health facilities. However, the children's treatment services and short-term services were not significantly different in terms of costs even though they were lower. This means social franchising is benefiting its franchisee by providing quality services that are cost-effective. 5.4 Policy Recommendations In light of the study findings, its evident private healthcare consumers demand quality services which are affordable. This means service providers need to ensure services provided are of high quality and delivered at affordable costs. The study recommends that private healthcare providers should consider joining a franchise network as the findings of the study found there are benefits which includes people perceive services to be of high quality. The findings also shown that consumer’s budget line is pushed outward leaving consumers with more money to consume for other critical services. 5.5 Areas for Further Research This study suggests the methodology be replicated in other counties and future researchers may consider one franchisor at a time in their analyses. There is a need to also conduct a study on the supply side and acquire qualitative responses on the experiences of providers in the franchised network. REFERENCES Abiye, Z., Tesfaye, A., & Hawaze, S.

APPENDIX I: INTRODUCTION LETTER Hello Sir/Madam, my name is Stephen Kariuki Nyaga, a student from the school of economics, Kenyatta University pursuing a Master's degree in Economics. As part of the Kenyatta University requirement am required to conduct a study that adds value to the policy framework. I am contacting you to request your participation in a research study that I am conducting for my project and you have been randomly selected to participate in this research as a person living near a private clinic. The purpose of this study is to understand the cost of healthcare services you seek in private clinics. These services include family planning services and children services. Procedures: If you choose to participate, we shall ask you a few questions about the cost of the services you received in this clinic and your preference for this clinic. The survey will take approximately 5-10 minutes. Risks and benefits: There are no direct benefits to participating in this study. It’s hoped the information you give will help policymakers, researchers and scholars understand the cost of services charged in these clinics and therefore come up with policies that would increase access to services offered in private health facilities. We anticipate very minimal risks associated with participating in this study. If any of the questions asked to make you feel uncomfortable, please feel free to decline to answer or end the interview at any time. Confidentiality: The information you provide is utterly confidential. We are not asking any information that may directly identify you nor the clinics in which you attend. All information gathered in this study will be generalized. Voluntary participation: Lastly, please note that this research is voluntary. You may accept to respond or refuse to respond without any negative consequences. I am therefore humbly requesting a few minutes of your time for this short survey. May I start this short survey?
