The Arab Spring has led to very different outcomes across the Arab world. I present a highly stylized model of the Arab Spring to better understand these differences. In this model, dictators from the ethnic or religious majority group concede power if their country is oil-poor, but can stay in...

Publication and citation rankings have become major indicators of the scientific worth of universities and countries, and determine to a large extent the career of individual scholars. We argue that such rankings do not effectively measure research quality, which should be the essence of...

This contribution examines the role of capitalism in anti-American terrorism. Using data for 149 countries between 1970 and 2007, this contribution, contrary to expectations from capitalist peace theory, does not find that Anti-American terrorism increases with external economic liberalization...

This paper does three things. First, based on a limited number of theoretically established dimensions, it proposes a new de facto indicator for the rule of law. It is the first such indicator to take the quality of legal norms explicitly into account. Second, using this indicator we shed new...

We empirically investigate the existence of spatial autocorrelation between military dictatorships in Sub-Saharan Africa from 1977 through 2007. We apply a Bayesian SAR probit regression, extended to a pooled model. We find a robust and positive spatial autocorrelation coefficient, which shows a...

A new line of theoretical and empirical literature emphasizes the pivotal role of fair institutions for growth. We present a model, a laboratory experiment, and a simple cross-country regression supporting this view. We model an economy with an unequal distribution of property rights, in which...
