We provide evidence on the mechanisms linking resource-related income shocks to conflict, focusing specifically on illegal crops. We hypothesize that the degree of group competition over resources and the extent of law enforcement explain whether opportunity cost or contest effects dominate....

We provide evidence about the mechanisms linking resource-related income shocks to conflict. Combining temporal variation in international drug prices with spatial variation in the suitability to produce opium, we show that higher drug prices reduce conflict over the 2002-2014 period in...

We provide new evidence about the mechanisms linking resource-related income shocks to conflict. To do so, we combine temporal variation in international drug prices with new data on spatial variation in opium suitability to examine the effect of opium profitability on conflict in Afghanistan....
