We were asked to discuss specific methodological approaches to evaluating three hypothetical interventions. This article uses this forum to discuss three misperceptions about randomized trials. First, nobody argues that randomized trials are appropriate in all settings, and for all questions....

Human development, in combination with technology, yields economic growth which, in turn, is necessary to generate further advances in human development. This paper focuses on the first channel above and finds the relationship significant. Secondly, the paper tries to investigate what affects...

This paper compares Japan and the US as they provide different types of capital to the developing world, focusing especially on foreign aid and, to some extent, also on remittances and the role of NGOs. The main focus is on the quality of aid and on past conceptual differences and on an emerging...

Standard theories of resource allocation within the household posit that parents’ investments in their children reflect a combination of children’s endowments and parents’ preferences for child quality. We study how changes in children’s cognitive endowments affect the distribution of...

There is little doubt that technology change, both in terms of its process and quality dimensions, represents the principal driving force to explain comparative economic performance at both micro and macro levels. This paper examines the sources of technology change and the impediments to the...

Microcredit seeks to promote business growth and improve well-being by expanding access to credit. We use a field experiment and follow-up survey to measure impacts of a credit expansion for microentrepreneurs in Manila. The effects are diffuse, heterogeneous, and surprising. Although there is...

This paper suggests that area studies and economics have a better chance to be married successfully if we shift our attention from the exclusive emphasis on economic growth towards improvements in human development, especially the much broadened version of that concept. Different areas are shown...

The literature evaluating population and health policies is in flux, with many disciplines exploring biological and behavioral linkages from fetal development to chronic disease, disability, and late life mortality. The focus here is on research methods, findings, and questions that economists...

Group liability in microcredit purports to improve repayment rates through peer screening, monitoring, and enforcement. However, it may create excessive pressure, and discourage reliable clients from borrowing. Two randomized trials tested the overall effect, as well as specific mechanisms. The...

Why did Victorian Britain invest so much capital abroad? We collect over 500,000 monthly returns of British and foreign securities trading in London and the United States between 1866 and 1907. These heretofore-unknown data allow us to better quantify the historical benefits of international...
