The effects of offshoring on the elasticity of labor demand

In this paper, I use detailed plant-level data to analyze the relationship between offshoring and labor demand elasticities in the U.S. manufacturing sector during the 1972-2001 period. The results suggest that conditional demand elasticities for production workers are positively associated with increased exposure to offshoring both in the short-run and in the long-run. This relationship holds both for the unbalanced panel of plants and, for plants which continue their operations throughout the sample period. Controlling for skill biased technical change does not alter the magnitude or the significance of the estimated positive relationship between offshoring and labor demand elasticities.     

Exposure to the new wave of offshoring: An unemployment perspective

This paper examines the impact of increasing service offshoring in a two‐sector economy. We find that it leads to lower domestic unemployment if the marginal task‐specific offshoring cost in the service sector is sufficiently large. Under this condition, the jobs created due to enhanced productivity outweigh the jobs that are destroyed. The reduction in unemployment increases the cost of hiring domestic workers, thus encouraging firms in the manufacturing sector to increase their offshoring scale and productivity. This, in turn, increases their cost savings and may lead to a further decrease in unemployment. Hence, complementarity between two sectors’ offshoring activities may emerge. We calibrate the model using economic parameters from Belgium, and the calibration results predict varied unemployment trends and impacts on manufacturing‐sector offshoring activities with different task‐specific offshoring cost schedules.     

Unemployment and relative labor market institutions between trading partners

This paper contributes to the literature that highlights the role of trading partners' institutions for a country's unemployment rate. The objective is to study whether the results established in the minimum wage-setting of Davis (1998) hold when unemployment is driven by search frictions. This paper finds that relative labor market institutions matter for equilibrium unemployment as they generate comparative advantages, but there are two main differences with Davis. With North-North trade, unemployment decreases in the low-regulation country. When South is brought into the picture, low-regulation North is not insulated, and unemployment increases in both developed countries as a result of specialization.     

Persistent real exchange rates

Over the past decades, product market deregulation has typically preceded labor market reforms in OECD countries. This paper incorporates labor market rigidities in a model of footloose capital in order to study how globalization might affect the trade-offs generated by labor market regulation and put pressure on labor market institutions. In this two-sector model, globalization ultimately reduces labor market rigidities through either one of two channels: capital mobility triggers a re-allocation of resources, which trade integration amplifies, away from the high-rent / highly-unionized sector; the threat of costly relocations encourages labor market deregulation. The latter channel is more efficient because it avoids sub-optimal sectoral specialization.     

Equilibrium Unemployment and Endogenous Public Sector Employment

This paper develops a model of the equilibrium rate of unemployment with an endogenous share of public sector employment. We show how various macroeconomic shocks drive up the equilibrium rate of unemployment, accompanied by predictable variations in the public sector share of employment. In particular, under the empirically plausible assumptions that the public sector is relatively labor-intensive and the elasticity of substitution between capital and labor is less than unity, public sector employment is shown to be countercyclical. When the equilibrium unemployment rate rises over a prolonged time period, the public sector share of employment also rises.     

The Trouble with Offshoring: Static and Dynamic Losses in the Presence of Unemployment

This study provides theoretical support for the popular objection to offshoring, whereby firms at home employ services of labour located abroad. In the presence of unemployment, our analysis highlights welfare losses from offshoring – not only for the static case of a fixed stock of capital, but also for the dynamic one of optimal saving and investment. We compare these static and dynamic losses to the gains that would instead arise under full‐employment conditions, assumed by most of the theoretical literature on offshoring. Our results suggest that public concerns over offshoring are justified when unemployment is taken explicitly into account.     

Volatility due to offshoring: Theory and evidence

Existing models of offshoring are not equipped to explain how global production sharing affects the volatility of economic activity. This paper develops a trade model that can account for why offshoring industries in low wage countries such as Mexico experience fluctuations in employment that are twice as large as in high wage countries such as the United States. We argue that a key to explaining this outcome is that the extensive margin of offshoring responds endogenously to shocks in demand and transmits those shocks across borders in an amplified manner. Empirical evidence supports the claim that the extensive margin of offshoring is an active margin of adjustment, and quantitative simulation experiments show that the degree of movement of this margin in the data is sufficient to explain relative employment volatility in Mexico and the U.S.     

Trade, offshoring, and the invisible handshake

We study the effect of globalization on the volatility of wages and worker welfare in a model in which risk is allocated through long-run employment relationships (the ‘invisible handshake’). Globalization can take two forms: international integration of commodity markets (i.e., free trade) and international integration of factor markets (i.e., offshoring). In a two-country, two-good, two-factor model we show that free trade and offshoring have opposite effects on rich-country workers. Free trade hurts rich-country workers, while reducing the volatility of their wages; by contrast, offshoring benefits them, while raising the volatility of their wages. We thus formalize, but also sharply circumscribe, a common critique of globalization.     

Migration and trade: Theory with an application to the Eastern-Western European integration

The remarkable increase in trade flows and in migratory flows of highly educated people are two important features of globalization of the last decades. This paper extends a two-country model of inter- and intra-industry trade to a rich environment featuring technological differences, skill differences and the possibility of international labor mobility. The model is used to explain the patterns of trade and migration as countries remove barriers to trade and to labor mobility. We parameterize the model to match the features of the Western and Eastern European members of the EU and analyze first the effects of the trade liberalization which occurred between 1989 and 2004, and then the gains and losses from migration which are expected to occur if legal barriers to labor mobility are substantially reduced. The lower barriers to migration would result in significant migration of skilled workers from Eastern European countries. Interestingly, this would not only benefit the migrants and most Western European workers but, via trade, it would also benefit the workers remaining in Eastern Europe.     

Wage bargaining and multinational firms

We set up a general equilibrium model with heterogeneous firms to study the interaction between wage bargaining and foreign direct investment. Thereby, we highlight the incentives of firms to invest abroad in order to improve their bargaining position vis-á-vis local unions and we show how changes in the bargaining power of unions affect the share of multinational firms in an open economy. In addition, taking into account this relationship between wage bargaining and foreign direct investment, our analysis provides novel insights on how labor income and the unemployment rate adjust to economic integration and how changes in the bargaining power of unions affect these two labor market variables.     

International trade and macroeconomic dynamics with labor market frictions

This paper studies how labor market frictions affect the consequences of trade integration in a two-country dynamic stochastic general equilibrium model with heterogeneous firms and endogenous producer entry. Two main results emerge. First, trade integration is beneficial for welfare by inducing higher productivity, but unemployment can temporarily rise during the transitional adjustment. Labor market rigidities reduce gains from trade, even though they can mitigate short-run employment losses. Second, consistent with the data, the model predicts that stronger trade linkages lead to increased business cycle synchronization. The strength of this effect, however, depends on the labor market characteristics of the integrating partners.     

Outsourcing, unemployment and welfare policy

The paper investigates the consequences of outsourcing of labor intensive activities to low-wage economies. This trend challenges the two basic functions of the welfare state, redistribution and social insurance when private unemployment insurance markets are missing. The main results are: (i) outsourcing raises unemployment and labor income risk of unskilled workers; (ii) it increases inequality between high- and low-income groups; and (iii) the gains from outsourcing can be made Pareto improving by using a redistributive linear income tax if redistribution is initially not too large. We finally derive the welfare optimal redistribution and unemployment insurance policies.     

Remittances and the Dutch disease

Using data for El Salvador and Bayesian techniques, we develop and estimate a two-sector dynamic stochastic general equilibrium model to analyze the effects of remittances on emerging market economies. We find that, whether altruistically motivated or otherwise, an increase in remittance flows leads to a decline in labor supply and an increase in consumption demand that is biased toward non-tradables. The higher non-tradable prices serve as incentive for an expansion of that sector, culminating in reallocation of labor away from the tradable sector — a phenomenon known as the Dutch disease. Quantitative results also indicate that remittances improve the welfare of households because they smooth income flows and increase consumption and leisure levels. A BVAR analysis provides results that are consistent with the dynamics of the model.     

The Effects of Globalisation on the US Labour Mark'et: Service Sectors Considered

How has globalisation affected employment and wages in the United States? Existing studies largely ignore the intersector labour movement between the manufacturing and service sectors by focusing only on the intrasector movement within the manufacturing sector. However, by decomposing the aggregate labour demand in the United States, we find that the intersector movement is more substantial than intrasector movement. Motivated by the decomposition results, this study presents a three‐sector model that includes a manufacturing sector and two service sectors at varying skill intensities. The model shows that offshoring might translate into smaller‐than‐expected wage changes because of the intersector labour movement. In line with the theoretical predictions, two notable empirical results are presented. First, an occupation's exposure to offshoring has non‐significant, albeit negative, effects on wages. Second, the more an occupation is exposed to offshoring, the lower its employment in the manufacturing sector as a share of its total employment. Furthermore, these effects are larger for more routine occupations or those requiring less education.     

Home bitter home: How labor protection influences firm offshoring

Drawing on the home country literature, we argue that firms headquartered or located in countries with strong labor protection may face challenges in their domestic operations. These firms are likely to initiate offshoring to enhance operational efficiency. Building on this argument, we also examine the boundary conditions moderating this proposed effect including labor productivity and employee stock ownership. Results based on a sample of information technology firms operating within five developed countries during 1990–2010 provide support for these arguments. These findings suggest that offshoring can be a partial exit strategy for firms to address the institutional challenges in their home country.     

中国城乡劳动力流动影响因素研究——理论模型与实证分析

结合中国实际情况,对哈里斯-托达罗模型的基本假设进行修定,从农民追求预期净收益现值最大化出发,运用动态宏观经济学的递归方法,推导出均衡条件下中国城乡劳动力流动影响因素的理论模型,并采用动态面板计量方法实证检验各影响因素对城乡劳动力流动的作用方向和程度。研究发现：城乡劳动力流动率的滞后值、城乡实际收入差距、非农产值比和农业比较劳动生产率对城乡劳动力流动有正的影响,但城乡实际收入差距的影响系数值偏小;城镇失业率、城乡消费支出比和农村工业化对城乡劳动力流动有负的影响;制度变迁和全社会固定资产投资率对城乡劳动力流动也有一定程度但不显著的正影响。为了解决农民工就业问题,应加强城乡联动共同发展。     

Protection and unemployment

Job loss concerns strongly influence the politics of trade, yet the formal political economy of trade literature has largely ignored unemployment. This paper seeks to extend the literature by merging an unemployment model with a trade policy model. The theory implies that labor turnover rates and unionization rates may significantly affect protection for individual industries. I use US data to test the model and find that protection for an industry declines with its turnover rate and increases with its unionization rate. The results also imply that protection does not increase with output and increases with the number of unemployed workers.     

A SCHUMPETERIAN GROWTH MODEL WITH EQUILIBRIUM UNEMPLOYMENT

We introduce efficiency‐wage unemployment in a model of growth with endogenous technical change. Our research aim is twofold. First, we try to provide an analytically tractable model of growth with efficiency‐wage unemployment that can be viewed as alternative to the standard models of growth and search unemployment. Second, we try to analyze the steady‐state effects of some labor market policies on unemployment and growth. We find that a positive relationship between growth and unemployment exists and that the effectiveness of any labor market policy aimed at improving the performance of the labor market crucially depends on how individuals discount future income.     

Why trucks jump: Offshoring and product characteristics

In this paper, we study the role of vertical product differentiation in the decision to allocate production between domestic and foreign plants. To do so, we examine the first wave of light-truck offshoring to Mexico that occurred due to substantially lower post-NAFTA trade barriers and a coincident increase in US demand for light trucks. In contrast to the typical assumption, but similar to many other industries, the need for additional capacity was accommodated by investment in both the US and Mexico for the same models of light trucks. Using a new dataset that details the extent of offshoring and domestic production within models, we document sharp differences in how capacity was utilized. Specifically, within models, we find that automakers offshored varieties which tend to be older in design vintage, lower scale, and less complex to produce. In contrast, we find that varieties “inshored” to newer capacity in the US exhibit the opposite characteristics. This highlights the important role of vertical differentiation and the associated variation in production complexity for the sorting of production across borders. A product with a large degree of vertical differentiation may provide scope for a firm to maximize profits by “inshoring” the more complex varieties while offshoring the less complex versions.     

Terms of trade risk with partial labor mobility

We examine the welfare consequences of terms-of-trade risk in a small open economy in which it is costly for workers to move between sectors. Relocation costs lead to partial labor mobility, sectoral wage gaps and income risk exceeding that of an economy in which relocation is costless. Using observed wage differentials and standard values for volatility and preferences, we find that the welfare cost of partial labor mobility alone is unlikely to be very large, even in the absence of self-insurance arrangements. In addition, modest consumption substitution elasticities significantly reduce these welfare costs.
