This paper examines the micro and macro correlates of aid project outcomes in a sample of 3,821 World Bank projects and 1,342 Asian Development Bank projects. Project outcomes vary much more within countries than between countries: country-level characteristics explain only 10?25 percent of...

Does research add value to aid? Specifically, does impact evaluation research help or hinder the delivery of development projects? This paper analyzes the question by constructing a new data set of 100 impact evaluations and 1,135 projects approved by the World Bank between 2005 and 2011. The...

This paper uses regression analysis to identify which country context, reform content, process, and project management variables predict the performance of public sector management projects, as measured by the Independent Evaluation Group's project outcome ratings. The paper draws on data from a...

The literature on aid and growth has not found a convincing instrumental variable to identify the causal effects of aid. This paper exploits an instrumental variable based on the fact that since 1987, eligibility for aid from the International Development Association (IDA) has been based partly...

A number of recent studies have empirically documented links between characteristics of World Bank projects and their ultimate outcomes as evaluated by the World Bank's Independent Evaluation Group. This paper explores the in-sample and out-of-sample predictive performance of empirical models...

Aid is good for the poor. This paper uses detailed aid data spanning 60 developing countries over the past two decades to show that social aid significantly and directly benefits the poorest in society, while economic aid increases the income of the poor through growth. This new and unequivocal...

This study investigates the effects of the World Bank's exogenously-determined income threshold for eligibility for concessionary International Development Association (IDA) loans on the allocations of bilateral donors. The donors might interpret the World Bank's policies and allocations across...

In the 21st century, many developing countries will become emerging markets and will no longer be in need of the carrot-and-stick approach to development assistance most prevalent today: development financing made available conditional on certain policies and interventions. This paper suggests...

This paper presents a comprehensive review of the operations that the World Bank has supported to create jobs and promote employment in fragile and conflict-affected situations. A novel approach to identifying projects is presented that enables searching for projects based on stated development...

Habitat conservation is critical to the survival of endangered tigers. This paper develops a resource-allocation model for the protection of tiger habitats, using information on threats to particular tiger subspecies, the quality of remaining habitat areas, the observed effectiveness of habitat...
