Labor Market Institutions, Firm-specific Skills, and Trade Patterns

This paper studies how cross-country differences in labor market institutions shape the pattern of international trade, focusing on workers’ skill acquisition. I develop a model in which workers un-dertake non-contractible activities to acquire firm-specific skills on the job. In the model, workers have more incentive to acquire firm-specific skills relative to general skills in a more protective labor market. When sectors are different in the dependence on these two types of skills, workers’ skill acquisition turns labor laws into a source of comparative advantage. By embedding the model in an open-economy framework with heterogeneous firms, sectors with different levels of dependence on firm-specific skills, and countries with varying degrees of labor protection, I show that countries with more protective labor laws export relatively more in firm-specific skill-intensive sectors through both the intensive and extensive margins of trade. I then estimate returns to firm tenure for different U.S. manufacturing sectors over the period of 1974-1993, and use the estimates as sector proxies for firm-specific skill intensity to test the theoretical predictions. By implementing the Helpman-Melitz-Rubinstein (2008) framework to estimate sector-level gravity equations for 84 countries in 1995, I find supporting evidence for the predicted effects of labor market institutions on both margins of trade.Labor market institutions, heterogeneous �rms, margins of trade, trade patterns, firm-specific skills

Do Information and Communication Technologies Empower Female Workers? Firm-Level Evidence from Viet Nam

This paper studies the effects of firms’ investments in information and communication technologies (ICT) on their demand for female and skilled workers. Using the gradual liberalization of the broadband Internet sector across provinces from 2006 to 2009 as a source of exogenous variation to identify the causal impacts of ICT, we find evidence from the country’s comprehensive enterprise survey data that firms’ adoption of broadband Internet and other related ICT increased their relative demand for female and college-educated workers. The effect of ICT on firms’ female employment is particularly strong among the college-educated workers, and is stronger in industries that are more dependent on highly manual and physical tasks. These results suggest that ICT can lower gender inequality in the labor market by shifting the labor demand from highly manual, routine tasks in which men have a comparative advantage toward more nonroutine, interactive tasks in which women hold a comparative advantage. However, the effect of ICT is weaker in industries relying more on complex and interactive tasks, suggesting that gender differences in education may have limited female labor supply for the most innovative industries that require highly technical skills to complement ICT

The Determinants of Vertical Integration in Export Processing: Theory and Evidence from China

Using detailed product-level export data for China and a variant of the Antràs and Helpman (2004) model that includes investments in component search, we examine the sectoral determinants of foreign direct investment (FDI) versus foreign outsourcing in export processing trade. We exploit the coexistence of two regulatory export processing regimes in China, which specify who owns and controls the imported components for export processing. We find that in the regime that Chinese plants own the imported components, the share of exports from vertically integrated plants is increasing in the intensity of headquarter inputs across sectors, and is decreasing in the contractibility of inputs. These results are consistent with the property- rights theory of intra-firm trade. However, in the regime that foreign firms own the imported components, no significant relationship is found between the prevalence of vertical integration, headquarter intensity and input contractibility across sectors. The positive relationship between productivity dispersion and the export share of integrated plants across sectors, as suggested by the existing literature, is found only in the regime that foreign firms own the imported components. These results are consistent with our model, which considers ownership of imported components as an alternative to asset ownership to alleviate the hold-up problem by the export-processing plant.Intrafirm trade, vertical integration, export processing, outsourcing

The Impact of New Immigration in native Wages: A Cross-occupation Analysis of a Small Open Economy

This paper examines how immigration affects native wages by exploiting an unexpected episode of immigrant influx. The episode happened in Hong Kong, when its government unexpectedly relaxed the restriction on immigration from mainland China in 1993, resulting in a seven-fold increase in the net inflow of Chinese immigrants between 1992 and 1993. We use variation in the employment share of immigrants across occupations for identification. To tackle endogeneity between wages and immigrant inflows across occupations, we use Welch’s (1999) congruence indices, which capture the degree of substitutability between workers from different skill groups, to construct instruments for the prevalence of Chinese immigrants in an occupation. Using micro-level data, our two-stage-least-squares estimates show that a 1 percentage point increase in the ratio of new Chinese immigrants to natives decreases native monthly real wages in the same occupation by 2.8-3.6 percents (controlling for immigrant shocks in similar occupations). Within an occupation, female and more skilled native workers experience more adverse wage impact, reflecting a high switching cost associated with occupation-specific human capital.Immigration, Labor Market Outcomes, Occupation-specific Human Capital

Based on a variant of the Antràs-Helpman (2004) model, we show theoretically that control over imported components for assembly can affect firm integration decisions. Our empirical results show that when Chinese plants control the use of components, the export share of foreign-owned plants is positively correlated with the intensity of inputs provided by the headquarter (capital, skill, and R&D). These results are consistent with the property-rights theory of intra-firm trade. However, when foreign firms own and control the components, there is no evidence of a positive relationship between the intensity of headquarters' inputs and the prevalence of vertical integration.

We develop a statistical decision model in which a firm updates its prior belief about demand in a foreign market based on several factors, including the number of neighbors currently selling there, the level and heterogeneity of their export sales, and the firm's own prior knowledge about the market. A positive signal about demand inferred from neighbors' export performance raises the firm's probability of entry and initial sales in the market but, conditional on survival, lowers its post-entry growth. These learning effects are stronger when there are more neighbors to learn from or when the firm is less familiar with the market. We find supporting evidence for the main predictions of the model from transaction-level data for all Chinese exporters over the 2000-2006 period. Our findings are robust to controlling for firms' supply shocks, countries' demand shocks, and city-country fixed effects

Since EP firms face less uncertainty, these facts can be rationalized in light of the heterogeneous-firm model with uncertainty in export sales, such as Fernandes and Tang (2014)

Essays on international trade and investment

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Economics, 2008.Includes bibliographical references.This dissertation consists of three essays on international trade and investment. In the first essay, I study how cross-country differences in labor market institutions shape the pattern of international trade with a focus on workers' skill acquisition. I develop an open-economy model in which workers undertake non-contractible activities to acquire firm-specific skills on the job. I show that protective labor laws, by increasing workers' bargaining power, induce workers to acquire more firm-specific skills relative to general skills. When sectors differ in the dependence on firm-specific skills in production, workers' investment decisions turn a country's labor laws into a source of comparative advantage. Specifically, the model predicts that countries with more protective labor laws export relatively more in firm-specific skill-intensive sectors. To test these hypotheses, I construct sector measures of firm-specific skill intensity using estimated returns to firm tenure in the U.S. over 1985-1993. Using these measures and a cross-country, cross-sector data set of 84 countries in 1995, I find support for the theoretical predictions. In the second essay, I use a firm-level panel data set of 90,000 Chinese manufacturing firms over the period of 1998-2001 to examine whether there exist productivity spillovers from foreign direct investment (FDI) to domestic firms in the same sector (horizontal spillovers), and in sectors supplying intermediate inputs to foreign affiliates (vertical spillovers through backward linkages). I find evidence of negative horizontal spillovers. While I find no evidence of vertical spillovers at the national level, domestic input suppliers' productivity growth decreases with the foreign presence in their downstream sectors in the same province.(cont.) Second, this essay examines whether the ownership structure of foreign affiliates affects the magnitude of spillovers. I find that wholly owned and ethnic-Chinese foreign firms are associated with more negative horizontal spillovers, compared to jointly owned and non-Chinese foreign firms, respectively. I also find that negative spillovers are mostly borne by domestic firms that are state-owned, technologically-backward and located in inland provinces. The third essay studies how government political ideology determines the pattern of trade protection across countries. I hypothesize that left-wing governments are associated with relatively higher protection in labor-intensive sectors, and relatively lower protection in capital- and human-capital intensive ones, than right-wing governments. Using a cross-country, cross-sector data set of 49 countries and 27 manufacturing sectors in the late 90s, I find evidence supporting these predictions.Heiwai Tang.Ph.D
