The impact of a multipronged approach to poverty alleviation on household outcomes Vilas Gobin 11 June 2015
Motivation The poorest of the poor often do not benefit from poverty alleviation programs, for example: The poorest benefit the least from MFIs (Morduch, 1999; Rabbani et al., 2006). Public assistance programs and social safety nets fail in targeting the poorest (Mukherjee, 2005; Jalan and Murgai, 2007; Banerjee et al., 2007). There is also limited evidence that public assistance programs and social safety nets lead to any long-term sustained graduation from dependency (Independent Evaluation Group, 2011). Motivation 2
Evidence that removing credit constraints alone may not be sufficient to alleviate poverty through microenterprises (Angelucci et al., 2014; Banerjee et al., 2014a; Banerjee et al., 2014b; de Mel et al 2012; Fafchamps et al., 2011; Karlan and Zinman 2010). Relaxing human capital constraints alone may also not be sufficient to alleviate poverty through microenterprises (McKenzie and Woodruff, 2014). Emerging evidence that both financial and human capital constraints need to be simultaneously addressed if microenterprises are to deliver on their transformative potential (de Mel et al., 2012; Berge et al., 2014; Bandiera et al. 2013; Banerjee et al., 2015). Motivation 3
The poverty graduation approach Challenging the Frontiers of Poverty Reduction – Targeting the Ultra-Poor A package of interventions including: consumption support, physical asset transfer, skills training, savings services. Ongoing support for 2 years at which time participants are expected to graduate from extreme poverty and be able to participate in microfinance. Reported Impacts Bandiera et al. (2013) – increase in earnings, expenditure, food security and life satisfaction (rural Bangladesh) Ultra-Poor Poverty Graduation pilots in 6 countries: India, Pakistan, Honduras, Peru, Ethiopia, Ghana Improvements in consumption, food security, assets, finance, income, time use, mental health, women’s decision making Morduch et al. (2012) – no impact on income, consumption or asset accumulation (Andhra Pradesh, India) Poverty Graduation Models 4

Randomisation of Program Assignment 1755 eligible women identified in November 2012 across 14 locations Limited capacity to enrol all women resulted in eligible women being split into three groups. Three groups were to be enrolled in either March/April 2013, September/October 2013 or March/April 2014 A public lottery was used to randomly assign women to one of the three funding cycles Research design, implementation, data 7 Funding CycleSample Size Group AApr Group BSep Group CApr

Conclusion Results 18 Providing ultra-poor women with capital and skills enables them to improve household incomes through entrepreneurial activities. Women are also better able to plan for future shocks through the accumulation of liquid savings as well as livestock. The poverty graduation model appears to have passed an extreme test of its ability to improve the lives of the ultra-poor Implemented in low population density region that is prone to insecurity and extreme climatic conditions, lacks infrastructure, and has limited access to markets.

Spillover Effects Not randomised by location so increased likelihood of spillover effects Control households may benefit from reduced prices in goods or increased availability of goods in location >90% enterprises are petty trade of primarily food items Not expected to be substantial given large number of pre-existing businesses Research design, implementation, data 24
Spillover Effects Research design, implementation, data 25 Table 5: Population, Villages and Number of Businesses by Location LocationPopulation* Number of Villages Pre-existent businesses Businesses formed between 2013 and 2014 Non- Program Program April 2013 September 2013 April *Population numbers based on the 2009 Kenya Census.
Spillover Effects Treatment groups may also experience decreased revenue and profits due to presence of other businesses Include business density as a control variable in estimation of program effect Control households may benefit from access to loans from SGs established under the program. SGs already exist in all locations prior to April 2013 We capture information on borrowing from program SGs so can control for this effect. Research design, implementation, data 26
Program Anticipation Participants may change behaviour in anticipation of receiving funding Participants informed of when they will receive funding during initial selection stage. If anticipation resulted in changes in behaviour that affect the outcomes of interest we would expect to see differences in these outcomes between Groups B and C at midline. Group B would have anticipated receiving funding 6 months before Group C We compare means of outcome variables between Groups B and C to check for any differences.
