Medical and public health innovations in the 1940s quickly resulted in significant health improvements around the world. Countries with initially higher mortality from infectious diseases experienced greater increases in life expectancy, population, and - over the following 40 years - social...

Exchanging one's vote for particularistic benefits - practices usually grouped under 'clientelism' - is often thought to weaken programmatic links between citizens and politicians and disincentivize public good provision, as well as undermine voter autonomy and the ideal role of elections....

We study the nature of regional inequality in Colombia over the past 200 years. The main empirical fact is that regional inequality has been highly persistent despite the large changes that have taken place and the modernization of the society. We show that regional inequality is highly...

English Abstract: We document the existence of a Crime Kuznets Curve in US states since the 1970s. As in come level shave risen, crime has followed an inverted U-shaped pattern, first increasing and then dropping. The Crime Kuznets Curve is not explained by income inequality. In fact, we show...
