High-performing charter schools can significantly increase the test scores of poor urban students. It is unclear whether these test score gains translate into improved outcomes later in life. We estimate the effects of high-performing charter schools on human capital, risky behaviors, and health...

Most of the future growth in energy use is forecast to come from the developing world. Understanding the likely pace and specific location of this growth is essential to inform decisions about energy infrastructure investments and to improve greenhouse gas emissions forecasts. We argue that...

Developing country governments are increasingly implementing cash assistance programs to combat poverty and inequality. This paper examines the potential tradeoffs between targeting these transfers towards low income households versus providing universal cash transfers, also known as a Universal...
