a b s t r a c t JEL classification: J61 O15 R23 Keywords: Labor Migration Inequality VietnamVietnam's economic boom during the transition to a market economy has centered on very rapid growth in some sectors and provinces, yet poverty has diminished across the entire country. With capital investments highly concentrated by province and sector, geographic labor mobility may be critical in spreading the gains from growth. Conversely, rising income inequality may be attributable in part to impediments to migration. We first use census data to investigate migration patterns and determinants. We then examine the role of migration as an influence on income ratios between pairs of provinces. The former analysis robustly confirms economic motives for migration but also suggests the existence of poverty-related labor immobility at the provincial level. Examination of income ratios between pairs of provinces reveals that the impact of migration on inequality can be either negative or positive. A robust inequality-reducing impact of migration is found for migration flows into provinces where most of Vietnam's trade-oriented industrial investments are located.

Shock therapy" transitions in Eastern Europe facilitated movement of skilled workers into privatized industries offering high wage premia relative to state industries. Other transitional economies (notably China and Vietnam) have been slower to relinquish control over key industries and factor markets. Some costs of this piecemeal approach are now becoming apparent. We examine the spillover of continuing capital market distortions into the market for a complementary factor, skilled labor. Using Vietnamese data we find that capital market segmentation creates a two-track market for skills, in which state sector workers earn high salaries while non-state workers face lower demand and lower compensation. Growth is reduced directly by diminished allocative efficiency and incentives to acquire education, and indirectly by higher wage inequality and rents for workers with access to state jobs.

This paper examines ways in which development policies interact and influence incentives for agricultural expansion in frontier areas. We develop a model of household response to economic and technical stimuli, conditional on agronomic and household characteristics. We evaluate the model empirically using survey data gathered from low-income corn and vegetable farms near a national park in the southern Philippines. We find that within farms, land allocation is responsive to relative crop prices and yields. However, different crops elicit different responses. In particular, some crop expansion takes place primarily through land substitution and intensified input use, while changes in prices or yields of other crops induce an expansion of total farm area. Land and family labor constraint bind at different points for different crops. These results suggest that because multiple policies interact, environmental policies must have multiple strands in order to replace incentives to further land expansion.JEL codes: Q12, Q24, O13.
