Public programs are designed to reach certain goals and beneficiaries. Methods to understand whether such programs actually work, as well as the level and nature of impacts on intended beneficiaries, are main themes of this book. Has the Grameen Bank, for example, succeeded in lowering consumption poverty among the rural poor in Bangladesh? Can conditional cash transfer programs in Mexico and Latin America improve health and schooling outcomes for poor women and children? Does a new road actually raise welfare in a remote area in Tanzania, or is it a 'highway to nowhere'?This book reviews quantitative methods and models of impact evaluation. It begins by reviewing the basic issues pertaining to an evaluation of an intervention to reach certain targets and goals. It then focuses on the experimental design of an impact evaluation, highlighting its strengths and shortcomings, followed by discussions on various non-experimental methods. The authors also cover methods to shed light on the nature and mechanisms by which different participants are benefiting from the program.For researchers interested in learning how to use these models with statistical software, the book also provides STATA exercises in the context of evaluating major microcredit programs in Bangladesh, such as the Grameen Bank. The framework presented in this book can be very useful for strengthening local capacity in impact evaluation among technicians and policymakers in charge of formulating, implementing, and evaluating programs to alleviate poverty and underdevelopment.

Bangladesh has the world's fastest growing, off-grid solar home system (SHS) coverage. In the past decade, the number of SHS installations has risen phenomenally–from a five-year target of 50,000 in 2003 to 50,000 a month in 2013, with support from the World Bank and other development partners. Even so, only 10 percent of off-grid households have been reached, suggesting ample room for continued expansion. Given the recent surge in SHS adoption, a key policy issue is whether the partial subsidy provided under the current program, implemented by the Infrastructure Development Company Limited (IDCOL), should be continued.Surge in Solar Powered Homes: Off-Grid Experience in Bangladesh assesses the country's remarkable growth in SHS, its support schemes, and the welfare impacts for rural households, using both large-scale household survey and institutional data. The book's findings clearly demonstrate that the social benefits from SHS adoption far exceed the cost of the subsidy. Within the current market incentive structure, there is tremendous scope for broadening the rural market reach. But the high upfront cost of purchasing a SHS at current market prices is a barrier to future sales, suggesting the continued need for IDCOL's well-targeted, subsidized operation.
