The importance of evolutionary forces for comparative economic performance across societies has been the focus of a vibrant literature, highlighting the roles played by the Neolithic Revolution and the prehistoric "out of Africa" migration of anatomically modern humans in generating worldwide...

This research explores the historical roots of the division of labor in pre-modern societies. It advances the hypothesis and establishes empirically that intra-ethnic diversity had a positive effect on the division of labor across ethnicities in the pre-modern era. Exploiting a variety of...

We analyze the endogenous evolution of economic and political institutions and the interdependencies with the process of economic development. Favorable economic institutions ensure the appropriability of rents in form of a state of law. We study the conditions under which a state of law can be...

We study the process of endogenous democratization from inefficient oligarchic systems in an economy where heterogeneous individuals can get involved in predation activities. The features of democracies are shown to be crucially related to the conditions under which democratization initially...

Economically highly developed countries are mostly democratic. But does this association constitute a causal relationship according to which democracy is a determinant of economic development? Or is it, conversely, economic development that paves the way for democratization? This paper gives an...

In this paper we use a panel of 189 countries to describe the salient trends that have emerged in national personal income tax systems spanning the twenty five year period from 1981 to 2005. Using complete national income tax schedules, we calculate actual average and marginal tax rates at...

Pooling data for 1905 to 2000, we find no systematic relationship between top income shares and economic growth in a panel of 12 developed nations observed for between 22 and 85 years. After 1960, however, a one percentage point rise in the top decile's income share is associated with a...

A notable feature of post-World War II civil wars is their very long average duration. We provide a theory of the persistence of civil wars. The civilian government can successfully defeat rebellious factions only by creating a relatively strong army. In weakly-institutionalized polities this...

This paper argues that openness to goods trade in combination with an unequal distribution of political power has been a major determinant of the comparatively slow development of resource- or land-abundant regions like South America and the Caribbean in the nineteenth century. We develop 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...
