The Rise of China and Labor Market Adjustments in Latin America

This paper assesses the impact of the rise of China on the trade of Latin American and Caribbean economies. The study proposes an index to measure the impact on trade, which suggests sizable effects, especially in Argentina, Brazil, Chile, Honduras, Mexico, and Paraguay. The paper uses the index and a model of labor mobility, to calculate the impact of Chinas growth on labor markets in Argentina, Brazil, and Mexico. The resulting evidence suggests that the rise of China has had positive effects on agriculture and mining in Argentina and Brazil, which offset negative impacts on manufacturing industries, thus leaving total employment and real wages virtually unchanged in the long run. In contrast, the estimated impacts of Chinas rise on Mexico imply that the sizable shock to manufacturing was not offset by the positive shocks on mining and agriculture, reducing employment in the long run. The paper also discusses the effect of China on the degree of informality in these three economies and contrasts short-run and long-run effects on employment and wages across industries.

Latent trade diversification and its relevance for macroeconomic stability

Traditional measures of trade diversification only take into account contemporaneous export baskets. These measures fail to capture a country’s ability to respond to shocks by allocating factors of production into activities for which it has already paid the fixed costs associated with exporting. This paper corrects for the shortcoming of traditional measures of diversification by introducing a novel measure of trade diversification—latent diversification—and proposes a proxy to measure latent diversification, which is calculated by taking into account the entire history of a country’s exports. The paper shows that the observed gaps between traditional measures of diversification and the proposed proxy of latent diversification are sizeable; countries hold latent export baskets that are, on average, three times as large as their average contemporaneous export basket, and these gaps are largest for poor and small countries. Moreover, latent diversification is an important determinant of volatility—more diversified latent export baskets are associated with lower terms of trade volatility and, subsequently, lower GDP per capita volatility, even after controlling for the degree of contemporaneous export diversification and other trade and country characteristics. The latter result, together with the disproportionately large latent baskets relative to contemporaneous baskets observed in poor and small countries, suggests that latent diversification is an important vehicle toward stability in countries that face barriers in building diversified contemporaneous export baskets.

Export shocks and the volatility of returns to schooling : evidence from twelve Latin American economies

This paper builds on previous studies to uncover evidence suggesting that cyclical fluctuations in returns to schooling are determined by fluctuations in foreign demand, which tend to be positively correlated with returns to schooling. The effect of export fluctuations (driven by changes in foreign demand) seems to be attenuated by labor market rigidities, such as constraints on employers to hire temporary workers on an hourly basis. This evidence suggests that countries that have flexible labor markets and experience volatility in their external demand might also experience volatility in returns to schooling. The paper discusses why this might be a concern for developing countries.
