This study explains the emergence of the Sicilian mafia in the XIX century as the product of the interaction between natural resource abundance and weak institutions. We advance the hypothesis that the mafia emerged after the collapse of the Bourbon Kingdom in a context characterized by a severe...

Using cross-country data, we find evidence for a significant negative interaction effect between democracy and inequality in determining the quality of growth-promoting institutions like rule of law. Democracy is associated with institutions of higher quality when inequality is lower.

In this paper we investigate the causal effect of life expectancy on economic growth by explicitly accounting for the role of the demographic transition. In addition to focusing on issues of empirical identification, this paper emphasizes the role of the econometric specification. We present a...

This paper investigates the role of violent civil conflicts during the process of democratization for the quality of emerging democracies, and in particular, the protection of civil (political and economic) liberties. A simple theory in which different groups may engage in violent conflict in...

This paper investigates the empirical role of violent conflicts for the causal effect of democracy on economic growth. Exploiting within-country variation to identify the effect of democratization during the Third Wave, we find evidence that the effect of democratization is weaker than reported...

Acemoglu, Johnson, Robinson, and Yared (2008) document that the cross-country correlation between income per capita and democracy disappears once including country fixed effects. This paper tests the hypothesis that the effect of income on democracy might differ systematically across countries....

We study the role of trade liberalization, democratization and their interaction for technology adoption. A general equilibrium theory with heterogeneous skills predicts a complementarity between trade and political regimes. Openness should accelerate technology adoption if coupled with...

We propose a unified growth theory to investigate the mechanics generating the economic and demographic transition, and the role of mortality differences for comparative development. The framework can replicate the quantitative patterns in historical time series data and in contemporaneous...
