This paper estimates the impact of corruption on growth of output per worker in U.S. states. The authors find that corruption plays a significant and causal role in lowering growth and investment across the States.

Robust institutional change is difficult to achieve.  However, the growth paths of some countries are more likely to be affected by contemporaneous political turmoil than others.  This paper supports this claim using data on GDP growth during periods of extreme political turmoil for 69 countries between 1870 and 2000.  The authors argue that the robustness of a country’s growth path to political uncertainty depends on the degree to which individuals are invested in its current institutions.

Whatever gains may come from fighting wars, economic growth is not among them.  This paper examines the long-run impact of interstate conflict on real GDP per capita for a cross section of countries between 1960 and 2000 and finds that a 10 percent increase in fatality-weighted conflict over that period results in an average decrease of 1.2 to 1.6 percent in 2000 real GDP per capita.
