Numerous digital health interventions have been piloted in response to the health care challenges low- and middle-income countries face. Because the opportunity cost of investing in digital health interventions can be large, countries must make choices about which interventions to scale up. To...

In many low- and middle-income countries, health coverage has improved dramatically in the last two decades, but health outcomes have not. As such, effective coverage -- a measure of service delivery that meets a minimum standard of quality -- remains unacceptably low. This Policy Research...

The identification of key determinants of aid effectiveness is a long-standing question in the development community. This paper reviews the literature on aid effectiveness at the project level and then extends the inquiry in a variety of dimensions with new data on World Bank investment project...

This study compares the magnitude of national level losses that the COVID-19 pandemic inflicted across three critical dimensions: loss of life, loss of income, and loss of learning. The well-being consequences of excess mortality are expressed in years of life lost, while those of income losses...

In lower-income countries, the economic contractions that accompany lockdowns to contain the spread of COVID-19 can increase child mortality, counteracting the mortality reductions achieved by the lockdown. To formalize and quantify this effect, we build a macro-susceptible-infected-recovered...

Analyzing the distributional impacts of economic crises is important and, unfortunately, an ever more pressing need. If policymakers are to intervene to help those most adversely impacted, then policymakers need to identify those who have been most harmed and the magnitude of that harm....

The disutility of work, often summarily described as effort, is a primal component of economic models of worker and consumer behavior. However, empirical applications that measure effort, especially those that assess the distribution of effort across known populations, are historically scarce....
