Millions of households in developing countries receive financial support from family members working overseas. How does the economic performance of overseas migrants affect origin-household investments—in particular, in child human capital and household enterprises? This paper examines Philippine households’ responses to overseas members’ income shocks. Overseas Filipinos work in dozens of foreign countries, which experienced sudden (and heterogeneous) changes in exchange rates due to the 1997 Asian financial crisis. Appreciation of a migrant’s currency against the Philippine peso leads to increases in household remittances received from overseas. The estimated elasticity of Philippine-peso remittances with respect to the Philippine/foreign exchange rate is 0.60. In addition, these positive income shocks lead to enhanced human capital accumulation and entrepreneurship in origin households. Favorable migrant shocks lead to greater child schooling, reduced child labor, and increased educational expenditure in origin households. More favorable exchange rate shocks also raise hours worked in selfemployment, and lead to greater entry into relatively capital-intensive enterprises by migrants’ origin households.
