We build a two country asymmetric DSGE model with two features: (i) a product cycle structure determines the range of intermediate goods used to produce new capital in each country and (ii) there are investment flow adjustment costs in the developing economy. We calibrate the model to match the Mexico-US trade and FDI flows. The model is able to explain (i) why US shocks have a larger effect on Mexico than in the US and hence why the Mexican economy is more volatile than the US; (ii) why US business cycles lead over medium term fluctuations in Mexico and (iii) why Mexican consumption is not less volatile than output.

This paper studies how the effect of trade openness on economic growth depends on complementary reforms that help a country take advantage of international competition. This issue is illustrated with a simple Harris-Todaro model where output gains after trade liberalization depend on the degree of labor market flexibility. In that model, trade protection may ameliorate the problem of underemployment (and underproduction) in sectors affected by labor market distortions; hence trade liberalization unambiguously increases per capita income only when labor markets are sufficiently flexible. We then present some panel evidence on how the growth effect of openness depends on a variety of structural characteristics. For this purpose, we use a non-linear growth regression specification that intera...

How do countries hold their financial wealth? We construct a new database of countries' claims on capital located at home and abroad, and international borrowing and lending, covering 68 countries from 1966 to 1997. We find that a small amount of capital flows from rich countries to poor countries. Countries' foreign asset positions are remarkably persistent, and mostly take the form of foreign loans rather than foreign equity. To interpret these facts, we build a simple model of international capital flows that highlights the interplay between diminishing returns, production risk and sovereign risk. We show that in the presence of reasonable diminishing returns and production risk, the probability that international crises occur twice a century is enough to generate a set of country port...
