A model of occupational choice,offshoring and immigration

This paper develops a two‐country model of offshoring and immigration with occupational choice and endogenous firm productivity. Individuals in Home choose to become entrepreneurs or workers, whereas those in Foreign can only be employed as workers. Entrepreneurs produce output using a fixed set of tasks that can be performed locally or abroad. The model predicts that pro‐immigration policies increase the number of entrepreneurs, raise productivity, and improve the aggregate welfare. It also predicts that lowering offshoring costs generates job polarization and welfare polarization, but improves the aggregate welfare.     

Selective Immigration Policies and Wages Inequality

We quantify the overall impact of immigration on native wages in France from 1990 to 2010. Our short‐run simulations indicate that immigration has decreased native wages by 0.6%. We find on average no impact of immigration on wages in the long run. However, we show that the long‐run effects of immigration on wages are detrimental to high‐skilled native workers and benefits to low‐skilled native workers. Our structural estimation allows us to evaluate the impact of “selective” migration policies. In particular, we find that selective immigration policies toward highly educated workers reduce the wage dispersion of French native workers.     

Intermediate good sourcing,wages and inequality: From theory to evidence

This paper examines the consequences of offshoring and outsourcing on domestic wages and wage inequality. I highlight the role of labor market frictions in impacting firms’ outsourcing and offshoring decisions; specifically, how differential costs of matching with workers affect the location of production (onshore or offshore) and how differential costs of assessing worker quality affect the ownership of intermediate production (intra‐firm or inter‐firm). I demonstrate how firm sourcing decisions can depend crucially on the industry skill intensity, which reflects the importance of worker–firm match quality, and as a result, the effect of offshoring on domestic labor depends on occupation and industry characteristics, as well as the ownership regime of trade. Bringing the theory to the data I rely on plausibly exogenous variation in the cost of inter‐ and intra‐firm offshoring to identify the effects of a change in each type of offshoring on domestic wages. I find strong evidence that the effect of offshoring on domestic wages—both on the average and on the wage distribution—is governed by the type of offshoring (inter‐ vs. intra‐firm), the skill intensity of the industry, and the offshorability of the occupation.     

Offshoring,tasks, and the skill-wage pattern

The paper investigates the relationship between offshoring, wages, and the occupational task profile using rich individual-level panel data. Our main results suggest that, when only considering within-industry changes in offshoring, we identify a moderate wage reduction due to offshoring for low-skilled workers, though wage effects in relation to the task profile of occupations are not estimated with sufficient precision. However, when allowing for cross-industry effects of offshoring, i.e. allowing for labor mobility across industries, negative wage effects of offshoring are quite substantial and depend strongly on the task profile of workers' occupations. A higher degree of interactivity and, in particular, non-routine content effectively shields workers against the negative wage impact of offshoring.     

IMMIGRATION UNEMPLOYMENT RELATIONSHIP: THE EVIDENCE FROM CANADA*

This paper examines the relationship between unemployment and immigration in Canada. The bi‐directional causality test finds no evidence of a significant effect of Canadian immigration on unemployment. Cointegration tests indicate that there is no observed increase in aggregate unemployment due to immigration in the long run. The results from the causality test based on the vector error correction model confirm that, in the short run, past unemployment does cause (less) immigration but not vice versa. There is also a long‐run positive relationship among per‐capita GDP, immigration rate and real wages. The results indicate that, in the short‐run, more immigration is possibly associated with attractive Canadian immigration policies, and in the long‐run, as the labour market adjusts, Canadian‐born workers are likely to benefit from increased migration.     

Trade,tasks and training: The effect of offshoring on individual skill upgrading

We offer a theoretical explanation and empirical evidence for a positive link between increased offshoring and individual skill upgrading. Skill upgrading takes the form of on‐the‐job training, complementing the existing literature, which mainly focuses on the retraining of displaced workers. To establish a link between offshoring and on‐the‐job training, we introduce an individual skill upgrading margin into the Grossman and Rossi‐Hansberg ( 2008 ) model of offshoring. By scaling up worker's wages, offshoring creates previously unexploited skill upgrading possibilities, which lead to more training. Using data from German manufacturing, we establish a causal link between industry‐level offshoring growth and increased individual skill upgrading.     

Unionization,international integration,and selection

Abstract We study how unionization affects competitive selection between heterogeneous firms when wage negotiations can occur at the firm or at the profit‐centre level. With productivity specific wages, an increase in union power has: (i) a selection‐softening; (ii) a counter‐competitive; (iii) a wage‐inequality; and (iv) a variety effect. In a two‐country asymmetric setting, stronger unions soften competition for domestic firms and toughen it for exporters. With profit‐centre bargaining, we show how trade liberalization can affect wage inequality among identical workers both across firms (via its effects on competitive selection) and within firms (via wage discrimination across destination markets).     

Immigration Policy,Self‐selection,and the Quality of Immigrants*

This paper investigates the effects of immigration quotas on the average quality of immigrants by developing a human capital migration model where efficiency in migration depends on skills and emigration rates are higher among skilled workers. Studying the joint determination of the domestic level of wages and immigrants' self‐selection, we find a negative relationship between the wage level and the percentage of educated workers among immigrants, which results in a nonstandard downward‐sloping labor supply. In our framework, a higher quota increases the skill mix of immigrants through its negative effect on wages and raises aggregate national income.     

International Factor Mobility,Wages and Prices

This paper analyzes the joint influence of migration inflows and outward foreign direct investment (FDI) on wage bargaining. Labor migration and offshoring supported by FDI affect wage deals by changing the outside options of workers and firms. Unemployed workers may find alternative jobs either in the legal or in the illegal labor markets. Wages in this latter case are highly affected by migrants crowding this segment more than any other market. Firms may have the option of moving production partly or entirely to foreign low‐cost countries. A wage curve is designed theoretically, reflecting cross‐border labor and capital mobility, and estimated on panel data for 13 European countries over the period 1995–2013. The theoretical predictions of a joint negative effect on wages of FDI outflows and labor migration inflows are confirmed with some novel results.     

The effects of offshoring to low-wage countries on domestic wages: a worldwide industrial analysis

This paper extends the literature on the implications of offshoring for labour markets by investigating its effect on the wages of different skill groups in a broad global context. The analysis draws on input–output data from the WIOD project, and in the panel analysed (13 manufacturing industries, 40 countries, 1995–2009) we account for up to 96 % of the international trade in manufacturing inputs. Being particularly interested in the wage effects of offshoring to low-wage countries (LWC), we use precise LWC classifications (varying across industries and time) to decompose overall offshoring by source country. We use a decomposition of the conventional offshoring measure in order to capture its pure international component, which is further instrumented using a gravity-based strategy. According to the estimation results, the negative impact of offshoring on wages mainly concerns low and medium skilled workers. However, in terms of magnitude, the downward pressure on domestic wages exhibited by offshoring to LWC is relatively small.     

Offshoring along the production chain

Abstract In this paper, we analyze the offshoring decision of firms whose production process is characterized by a particular sequence of steps. International cost differences vary non‐monotonically along the production chain, and moving unfinished goods across borders incurs transport costs. We show that, in such a setting, firms may refrain from offshoring even if relocating individual steps would be advantageous in terms of offshoring costs, or they may offshore (almost) the entire production chain to save transport costs. Small variations in model parameters may thus have a substantial impact on offshoring activities.     

EMPLOYMENT VERIFICATION MANDATES AND THE LABOR MARKET OUTCOMES OF LIKELY UNAUTHORIZED AND NATIVE WORKERS

As recent efforts to reform immigration policy at the federal level have failed, states have started to take immigration matters into their own hands and researchers have been paying closer attention to state dynamics surrounding immigration policy. Yet, to this date, there is not a clear understanding of the consequences of enforcing E‐Verify on likely unauthorized immigrants or on natives across the United States. This study aims to fill in that gap by analyzing the impact that the enactment of various types of E‐Verify mandates may have on the employment and wages of these groups. We find that the enactment of employment verification mandates reduces the employment likelihood of likely unauthorized workers. Additionally, it raises the hourly wages of likely unauthorized women. None of these impacts are observed among a similarly skilled sample of naturalized Hispanic immigrants. Finally, the enactment of E‐Verify mandates appears to raise the employment likelihood of alike non‐Hispanic natives, while raising the hourly wage of native‐born male employees, alluding to the potential substitutability of unauthorized immigrants and non‐Hispanic natives.

Offshoring and employment structure in the EU periphery: the case of Spain

The effects of offshoring of production have received a great deal of interest due to their implications on labour markets. However, the main theoretical predictions related to this issue are not always fulfilled in the empirical analysis; according to the Stolper–Samuelson theorem, there seems to be unanimous support for its effects in advanced countries whose production is relocated but not at all for recipient economies of the same. Additionally, there is a lack of empirical evidence in countries specialized in unskilled-labour tasks which are, at the same time, economies with higher relative wages in a global framework such as the Spanish economy. In this sense, the aim of this article is to analyse the effects of material offshoring in the relative composition of employment in the Spanish manufacturing industry during the period 1990–2007. Furthermore, we investigate the effects of immigrant labour and the temporary employment rate due to its increasing relevance in the Spanish economy during the period analysed. Using a generalized methods of moments (GMM) approach, our results suggest that, as opposed to most developed countries, offshoring in Spain has favoured the demand for blue-collar workers. In addition, we confirm that the increase in immigration and the increasing use of temporary contracts have enlarged the share of low-skilled workers.     

A SEARCH‐EQUILIBRIUM APPROACH TO THE EFFECTS OF IMMIGRATION ON LABOR MARKET OUTCOMES

We analyze the impact of the U.S. skill‐biased immigration influx that took place between 2000 and 2009 within a search and matching model that allows for skill heterogeneity, differential search cost, and capital‐skill complementarity. We find that although the skill‐biased immigration raised the overall net income to natives, it had distributional effects. Specifically, unskilled native workers gained in terms of both employment and wages. Skilled native workers, however, gained in terms of employment but lost in terms of wages. Nevertheless, in an extension where skilled natives and immigrants are imperfect substitutes, even the skilled wage rises.     

Offshoring,wages, and employment: Theory and evidence

This paper investigates the wage and employment effects of offshoring. I use firm-level data and two events in Mexico as a natural experiment to identify the effects of a fall in the marginal cost of offshoring to Mexico. I find that domestic wages actually rise at US firms likely to take advantage of this new offshoring opportunity. At the same time, domestic wages fall at US firms unlikely to take advantage of this opportunity. Furthermore, I find no evidence of greater domestic job loss at the former compared to the latter firms. These findings are consistent with productivity effects from offshoring. To explain the mechanism, I develop a theoretical framework that combines heterogeneous firms with imperfect labor markets and rent-sharing. Firms likely to take advantage of new offshoring opportunities increase their productivity and profitability at the expense of their competitors. Through rent-sharing, this channel leads to higher domestic wages at the former firms relative to the latter. Further, there is no empirical evidence of greater domestic job loss at the firms likely to expand their offshoring compared to their competitors that are unlikely to increase their offshoring.     

The Labour Market Impact of Adult Education and Training: A Cohort Analysis

Education boosts individuals' productivity and wages. Yet many individuals leave school with minimal skills and qualifications. One way for these workers to catch up might be lifelong learning. We find that a particular form of lifelong learning, work related training, does have a positive impact on earnings. However, firms tend only to train those workers who will gain from training. Training does benefit those chosen to receive it but if all workers received training, the average impact on wages would be low. Hence, this form of lifelong learning is not necessarily an effective way of raising wages.     

Intra‐firm trade,exporting, importing,and firm performance

Abstract This paper examines firm heterogeneity in terms of size, wages, capital intensity, and productivity between domestic and foreign‐owned firms that engage in intra‐firm trade, firms that export and import, firms that import only, and firms that export only. As previously documented, heterogeneity between different groups of trading firms is substantial. Taking into account intra‐firm trade in addition to exporting and importing yields new insights into the productivity advantage previously established for exporting firms. The results presented here show that this premium accrues only to exporters that also import and to exporters that also engage in intra‐firm trade, but not to firms that export only. Using simultaneous quantile regressions, the paper illustrates that heterogeneity within different groups of trading firm is equally large. Some of this within‐group heterogeneity can be attributed to differences in trading partners.     

Effort, trade, and unemployment

Abstract.  This paper incorporates equilibrium unemployment caused by efficiency wages into a monopolistic competition model of trade. Worker effort is treated as an endogenous variable that depends on the optimizing behaviour of firms and workers. Opening up trade induces firms to demand greater worker effort and to cut the size of their workforce. This counteracts the positive employment effect due to entry of firms. Circumstances are indicated in which the two effects just balance, leaving aggregate employment unchanged. Trade unambiguously increases worker effort, thereby enhancing within-firm productivity.     

Quota removal and firm-level offshoring: Theory and evidence

Recent literature indicates that offshoring can effectively increase firm productivity and improve product quality. Therefore, global value chains have increased in importance. In this paper, we investigate the impact of export growth on firm-level offshoring. Removal of the quota on textile and clothing products in importing countries boosts China's exports of quota-restricted products. This removal offers a quasi-natural experiment. Using a difference-in-differences approach, we find that export growth induced by the quota removal increases the extensive and intensive margins of firm-level offshoring. The impact is more pronounced on domestic firms and firms that are engaged in ordinary trade. Our findings suggest additional gains from trade liberalization: trade liberalization not only boosts exports, but also enhances firm productivity and product quality through encouraging firm-level offshoring.     

Temporary and Permanent Immigration under Unionization

This paper investigates permanent and temporary immigration and remittance under the coexistence of unionized and non‐unionized manufacturing firms in a two‐sector economy. The impacts of immigration and remittance on respectively wages, employment, the union–non‐union wage gap and national welfare are analyzed. It is found that both permanent immigration (economy‐wide) and temporary immigration in agriculture bring positive effects on most variables (except the competitive wage), but widens the wage gap and causes income redistribution in the host country. However, if temporary immigrants work in manufacturing only, then all wages and the union–non‐union wage gap fall. That is, workers become more equally paid but poorer. In addition, remittance and globalization cause negative effects on union workers and employers. It is perhaps such consequences and the income redistribution effect of immigration that cause the media to paint a negative image of immigration.
