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 research argues that deep-rooted factors, determined tens of thousands of years ago, had a significant effect on the course of economic development from the dawn of human civilization to the contemporary era. It advances and empirically establishes the hypothesis that in the course of the...

We investigate how nondemocratic regimes use the military and how this can lead to the emergence of military dictatorships. Nondemocratic regimes need the use of force in order to remain in power, but this creates a political moral hazard problem; a strong military may not simply work as an...

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...

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...

Praktisch alle wirtschaftlich entwickelten Länder der Welt sind demokratisch. Sind demokratische Strukturen also kausal für wirtschaftlichen Wohlstand und Wachstum? Oder ist es vielmehr der wirtschaftliche Entwicklungsstand eines Landes, der eine Demokratie erst ermöglicht? Dieser Artikel...

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...

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...

Although social institutions permeate the world in which we live, they are all but absent from our analyses of economic growth and development. This paper argues the need to mitigate this omission by demonstrating the importance of social institutions for growth and development.

New institutionalism has had considerable success during the last decade in shepherding the debate on sustained economic development. If the sociopolitical, legal and economic transformations in the Anglo-Saxon world in the last three decades prove anything, however, it is that the late Mancur...
