Global terrorist organizations attract radicalized individuals across borders and constitute a threat for both sending and receiving countries. We use unique personnel records from the Islamic State in Iraq and the Levant (Daesh) to show that unemployment in sending countries is associated with the number of transnational terrorist recruits from these countries. The relationship is spatially heterogeneous, which is most plausibly attributable to travel costs. We argue that poor labor market opportunities generally push more individuals to join terrorist organizations, but at the same time, limit their ability to do so when longer travel distances imply higher travel costs.

To fight evasion, many developing countries use production-inefficient tax policies. This includes minimum tax schemes whereby firms are taxed on either profits or turnover, depending on which tax liability is larger. Such schemes create nonstandard kink points, which allow for eliciting evasion responses to switches between profit and turnover taxes using a bunching approach. Using administrative data on corporations in Pakistan, we estimate that turnover taxes reduce evasion by up to 60–70 percent of corporate income. Incorporating this in a calibrated optimal tax model, we find that switching from profit to turnover taxation increases revenue by 74 percent without reducing aggregate profits.
