Self‐Selection into Credit Markets: Evidence from Agriculture in Mali - Working Paper 377

We partnered with a micro-lender in Mali to randomize credit offers at the village level. Then, in no-loan control villages, we gave cash grants to randomly selected households. These grants led to higher agricultural investments and profits, thus showing that liquidity constraints bind with respect to agricultural investment.

How Has the Developing World Changed since the Late 1990s? A Dynamic and Multidimensional Taxonomy of Developing Countries - Working Paper 375

Many existing classifications of developing countries are dominated by income per capita (such as the World Bank’s low, middle and high income thresholds), thus neglecting the multidimensionality of the concept of ‘development’. Even those deemed to be the main ‘alternatives’ to the income-based classification have income per capita heavily weighted within a composite indicator.

Why Don't Remittances Appear to Affect Growth? - Working Paper 366

While measured remittances by migrant workers have soared in recent years, macroeconomic studies have difficulty detecting their effect on economic growth. We review existing explanations for this puzzle and propose three new ones. First, we offer evidence that a large majority of the recent rise in measured remittances may be illusory—arising from changes in measurement, not changes in real financial flows.

On the Distributed Costs of Drug-Related Homicides - Working Paper 364

Reliable estimates of the effects of violence on economic outcomes are scarce. We exploit the manyfold increase in homicides in 2008-2011 in Mexico resulting from its war on organized drug traffickers to estimate the effect of drug-related homicides on house prices.
