We implemented a randomized field experiment that tested ways to stimulate migrants’ savings in their origin country. We find that migrants value opportunities to exert greater control over financial activities in their home countries. We offered U.S.-based migrants bank accounts in El Salvador, randomly varying migrant control over El Salvador–based savings by offering different accounts across treatments. Migrants offered the greatest degree of control accumulated the most savings. Impacts likely represent increases in total savings; there is no evidence that savings increases were simply reallocated from other savings mechanisms. Enhanced control over home country savings does not affect remittances sent home.

We ask how export demand shocks associated with the Asian financial crisis affected Chinese exporters. We construct firm-specific exchange rate shocks based on the precrisis destinations of firms' exports. Because the shocks were unanticipated and large, they are a plausible instrument for identifying the impact of exporting on firm productivity and other outcomes. We find that firms whose export destinations experience greater currency depreciation have slower export growth and that export growth leads to increases in firm productivity and other firm performance measures. Consistent with “learning-by-exporting,” the productivity impact of export growth is greater when firms export to more developed countries.

Increased enforcement can displace crime to alternative lawbreaking methods. This paper examines a customs reform in the Philippines that raised enforcement against a specific method of avoiding import duties. Increased enforcement applied only to shipments from some countries, so shipments from other countries serve as a control group. Increased enforcement reduced the targeted duty-avoidance method, but caused substantial displacement to an alternative method. The hypothesis of zero change in total duty avoidance cannot be rejected. Displacement was greater for products with higher tariff rates and import volumes, consistent with the existence of fixed costs of switching to alternative duty-avoidance methods.

This paper distinguishes between target-earnings and life cycle motivations for return migration by examining how Philippine migrants' return decisions respond to major, unexpected exchange rate changes in their overseas locations (due to the Asian financial crisis). Overall, the evidence favors the life cycle explanation: more favorable exchange rate shocks lead to fewer migrant returns.A10% improvement in the exchange rate reduces the 12-month return rate by 1.4 percentage points. However, some migrants appear motivated by target-earnings considerations: in households with intermediate foreign earnings, favorable exchange rate shocks have the least effect on return migration, but lead to increases in household investment.
