We investigate the impact of government ideology on left-wing as compared to conservative individuals. We find that conservative people are happier, on average. In a sample excluding the richest countries left-wing people are happier under the tenure of left-wing governments.

Using a country panel of domestic terror attacks from 1998 to 2004, we empirically analyze the impact of government decentralization on terror. Our results show that expenditure decentralization reduces domestic terror, while political decentralization has no impact.

We analyze the influence of terrorism on migration for 152 countries during 1976-2000. We find robust evidence that terrorism is among the 'push factors' of skilled migration, whereas it is not robustly associated with average migration.

We empirically analyze how other aid agencies, within and outside the United States, reacted to the Millennium Challenge Corporation (MCC). We find that positive signaling effects dominate possible substitution effects. Striving for MCC eligibility thus pays.

The typical identification strategy in aid effectiveness studies assumes that donor motives do not influence the impact of aid on growth. We call this homogeneity assumption into question, constructing a model in which donor motives matter and testing the assumption empirically.

We analyze the impact of political proximity to the United States on the occurrence and severity of terror. Employing panel data for 116 countries over the period 1975-2001 we find that countries voting in line with the U.S. are victims of more and deadlier attacks.
