We use Bayesian meta-analysis methods to estimate the impact of unconditional cash transfers (UCTs) on twelve primary outcomes from 114 studies of 72 UCT programs in middle and low income countries. Cash transfers generate strong and positive average treatment effects on ten of thirteen...

A policy of deputization asks agents to monitor others without providing explicit incentives. It is often used to prevent dangerous activities. To calibrate whether and why it works, we study recent laws that deputized financial professionals to help fight elder financial abuse. We show...

In a multiperiod investment framework, firms with high expected growth earn higher expected returns than firms with low expected growth, holding investment and expected profitability constant. This paper forms cross-sectional growth forecasts, and constructs an expected growth factor that yields...

Critics of foreign aid programs argue that these funds often support corrupt governments and inefficient bureaucracies. Supporters argue that foreign aid can be used to reward good governments. This paper documents that there is no evidence that less corrupt governments receive more foreign aid....

We document that, in rural Uganda, the entry of foreign aid reduces government provision of similar services because the organization that delivers aid often hires the government worker, thereby reducing state capacity. Access to any public services and population well-being worsen in villages...

We examine the supply-side and demand-side determinants of global bilateral food aid shipments between 1971 and 2008. First, we find that domestic food production in developing countries is negatively correlated with subsequent food aid receipts, suggesting that food aid receipt is partly driven...

This paper studies the impact of aid volatility in a two-period model where production may occur with either a traditional or a modern technology. Public spending is productive and "time to build" requires expenditure in both periods for the modern technology to be used. The possibility of a...

The Millennium Development Goals call for reducing by half the proportion of people without sustainable access to safe drinking water. This goal was adopted in large part because clean water was seen as critical to fighting diarrheal disease, which kills 2 million children annually. There is...

We examine one of the most important and intriguing puzzles in economics: why it is so hard to find a robust effect of aid on the long-term growth of poor countries, even those with good policies. We look for a possible offset to the beneficial effects of aid, using a methodology that exploits...
