Correlations across openness measures are sometimes weak, but openness does seem to be positively associated with GDP growth - the more open the economy, the higher the growth.

This essay surveys the evidence on the linkages between globalization and poverty. I focus on two measures of globalization: trade and international capital flows. Past researchers have argued that global economic integration should help the poor since poor countries have a comparative advantage in producing goods that use unskilled labor. The first conclusion of this essay is that such a simple interpretation of general equilibrium trade models is likely to be misleading. Second, the evidence suggests that the poor are more likely to share in the gains from globalization when there are complementary policies in place. Such complementary policies include investments in human capital and infrastructure, as well as policies to promote credit and technical assistance to farmers, and policies to promote macroeconomic stability. Third, trade and foreign investment reforms have produced benefits for the poor in exporting sectors and sectors that receive foreign investment. Fourth, financial crises are very costly to the poor. Finally, the collected evidence suggests that globalization produces both winners and losers among the poor. The fact that some poor individuals are made worse off by trade or financial integration underscores the need for carefully targeted safety nets.

Firms often cite financing constraints as one of their primary obstacles to investment. Global capital flows, by bringing in scarce capital, may ease host-country firms' financing constraints. However, if incoming foreign investors borrow heavily from domestic basnks, direct foreign investment (DFI) may exacerbate financing constraints by crowding host country firms out of domestic capital markets. Combininb a unique cross-country firm-level panel with time-series data on restrictions on international transactions and capital flows, we find that different measures of global flows are associated with a reduction in firm-level financing constraints. First, we show that one type of capital inflow--DFI--is associated with a reduction in financing constraints. Second, we test whether restrictions on international transactions affect firms' financing constraints. Our results suggest that only one type of restriction--those on capital account transactions--negatively affect firms' financing constraints. We also show that multinational firms are not financially constrained and do not appear to be sensitive to the level of DFI. This implies that DFI eases financing constraints for non-multinational firms. Finally, we show that DFI only eases financing constraints in the non-G7 countries.

Abstract: This paper draws together a variety of openness measures to test the association between openness and growth. Although the correlation across different types of openness is not always strong, there is generally a positive association between growth and different measures of openness. The strength of the association depends on whether the specification uses cross-section or panel data (which combines cross- section and time series). For industrializing countries, which have exhibited significant fluctuations in trade regimes over time, long run averages may not serve as very meaningful indicators of policy.

It seems that technology gains from foreign investment are captured entirely by joint ventures.

For some sectors the effect on import prices of investigating antidumping cases and countervailing measures is as great as imposing a duty. And investigations that end in duties have different effects than those resulting in no action.

This paper explores the relationship between wages and foreign investment in Mexico, Venezuela, and the United States. Despite very different economic conditions and levels of development, we find one fact which is robust across all three countries: higher levels of foreign investment are associated with higher wages. In Mexico and Venezuela, foreign investment was associated with higher wages only for foreign-owned firms -- there is no evidence of wage spillovers leading to higher wages for domestic firms. In the United States there is evidence of wage spillovers. The lack of spillovers in Mexico and Venezuela is consistent with significant wage differentials between foreign and domestic enterprises. In the United States, wage differentials are smaller.

In Mexico during the 1980s, the wages of more-educated, more- experienced workers rose relative to those of less-educated, less- experienced workers. We assess the extent to which the increase in the skilled-unskilled wage gap was associated with Mexico's recent trade reform. In particular, we examine whether trade reform has shifted employment towards industries that are relatively intensive in the use of skilled labor (Stolper-Samuelson-type effects). The results suggest that the rising wage gap is associated with changes internal to industries and even internal to plants that cannot be explained by Stolper-Samuelson-type effects. We also find that other characteristics associated with globalization -- such as foreign investment and export orientation -- matter. Exporting firms and joint ventures pay higher wages to skilled workers and demand more skilled labor than other firms.
