March 2015Religion and Innovation
with Roland Bénabou, Davide Ticchi, Andrea Vindigni: w21052
In earlier work (Bénabou, Ticchi and Vindigni 2013) we uncovered a robust negative association between religiosity and patents per capita, holding across countries as well as US states, with and without controls. In this paper we turn to the individual level, examining the relationship between religiosity and a broad set of pro- or anti-innovation attitudes in all five waves of the World Values Survey (1980 to 2005). We thus relate eleven indicators of individual openness to innovation, broadly defined (e.g., attitudes toward science and technology, new versus old ideas, change, risk taking, personal agency, imagination and independence in children) to five different measures of religiosity, including beliefs and attendance. We control for all standard socio-demographics as well as country...
September 2009Persistence of Civil Wars
with Daron Acemoglu, Davide Ticchi, Andrea Vindigni: w15378
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 opens the way for excessive influence or coups by the military. Civilian governments whose rents are largely unaffected by civil wars then choose small and weak armies that are incapable of ending insurrections. Our framework also shows that when civilian governments need to take more decisive action against rebels, they may be forced to build over-sized armies, beyond the size necessary for fighting the insurrection, as a commitment to not reforming the military in the future.

April 2008A Theory of Military Dictatorships
with Daron Acemoglu, Davide Ticchi, Andrea Vindigni: w13915
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 agent of the elite but may turn against them in order to create a regime more in line with their own objectives. The political moral hazard problem increases the cost of using repression in nondemocratic regimes and in particular, necessitates high wages and policy concessions to the military. When these concessions are not sufficient, the military can take action against a nondemocratic regime in order to create its own dictatorship. A more important consequence of the presence of a strong military...

December 2006Emergence and Persistence of Inefficient States
with Daron Acemoglu, Davide Ticchi, Andrea Vindigni: w12748
Inefficiencies in the bureaucratic organization of the state are often viewed as important factors in retarding economic development. Why certain societies choose or end up with such inefficient organizations has received very little attention, however. In this paper, we present a simple theory of the emergence and persistence of inefficient states. The society consists of rich and poor individuals. The rich are initially in power, but expect to transition to democracy, which will choose redistributive policies. Taxation requires the employment of bureaucrats. We show that, under certain circumstances, by choosing an inefficient state structure, the rich may be able to use patronage and capture democratic politics. This enables them to reduce the amount of redistribution and public ...
