Globalization,Wage Volatility,and the Welfare of Workers*

This paper analyzes the effects of trade liberalization on the level and volatility of factor returns, in a model with identical technologies across industries and industry‐specific uncertainty. The results show an increase in the return to capital and, under certain conditions, a decline in the real wages and welfare of workers, along with an expansion of wage dispersion and volatility. Unlike the Solper–Samuelson mechanism, our results do not depend on the factor intensity of imports and exports and are borne out by all patterns of trade, including among industrialized countries, suggesting that the traditional analysis has missed some important linkages between trade and wages.     

Decomposing the effect of trade on the gender wage gap

This paper uses variation in exposure to increased Chinese imports in Brazil to investigate the impact of trade on gender wage inequality. First, using Brazilian census data, we find that rising imports reduced the gender wage gap in Brazilian local labour markets. Next, using Oaxaca–Blinder decompositions, we show that this reduction in the wage gap was largely explained by trade increasing the share of female workers in higher-paying occupations. Finally, we use a matched employer–employee data set to investigate how individual workers adjust to the trade shock. Similar to the local labour market analysis, we find that male workers exposed to increased import competition saw a larger decline in both wages and cumulative earnings relative to female workers. In addition, we uncover an interesting asymmetry in that, while male workers exhibited much higher degrees of industry mobility in response to the trade shock, female workers exhibited an equal if not higher degree of occupational mobility.     

Who Trades with Whom? Exploring the Links between Firms' International Activities,Skills, and Wages

Using firm‐level data on the Italian manufacturing industry, we examine how trade activities are related to workforce composition and wages. We contribute to empirical research on these issues in three ways. First, we provide new evidence that is consistent with multi‐attribute models on firm heterogeneity and trade. We show that even after controlling for various company characteristics, including size and capital intensity, exporters still pay higher wages and employ more skilled workers than nonexporters. Second, we consider engagement in international transactions, either by means of exports, imports, or a combination of the two. We show that failing to control for importing activities may bias upward export premia. Third, we look at how the wage and the employment structures of trading firms change with the country of destination and origin of trade flows. We find that wage and skill premia are influenced by the characteristics of partner countries.     

Is there an export or import-led productivity growth in rapidly developing Asian countries? a multivariate VAR analysis

In contrast to cross-country studies, the paper investigates the relationships between trade and labour productivity for nine rapidly developing Asian countries in a time-series framework using a vector error-correction model. Independent tests on the long-run and short-run relationship between trade variables of exports and imports and productivity are conducted. The results suggest that trade has an important impact on productivity and output growth in the economy, however it is imports that provide the important?‘virtuous’?link between trade and output growth. The results indicate that exports and imports have qualitatively different impacts on labour productivity. The long-run result shows that there is no causal effect from exports to labour productivity growth for Hong Kong, Indonesia, Japan, Taiwan and Thailand; thereby suggesting that there is no export-led productivity growth in these countries. However, significant causal effects were found from imports to productivity growth, suggesting import-led productivity growth in India, Indonesia, Malaysia, Philippines, Singapore and Taiwan. In addition, the results indicate that imports tend to have greater positive impact on productivity growth in the long run.     

Equilibrium unemployment with outsourcing and wage solidarity under labour market imperfections

We evaluate the effects of outsourcing and wage solidarity on wage formation and equilibrium unemployment in a heterogeneous labour market, where wages are determined by a monopoly labour union. We find that outsourcing promotes the wage dispersion between the high- and low-skilled workers. When the labour union adopts a solidaristic wage policy, it will dampen this tendency. Further, higher outsourcing will increase equilibrium unemployment among the high-skilled workers, whereas it will reduce it among the low-skilled workers. Overall, outsourcing will reduce economy-wide equilibrium unemployment under the reasonable condition that the proportion of high-skilled workers is sufficiently low.     

The effect of taxation on labour supply: the case of moonlighting

The authors provide a simple test of supply-side economics by estimating the responsiveness of moonlighting labour supply to changes in the marginal tax rate and the wage rate. While standard theory teachers that changes in taxes and wage should have opposite and equal effects on labour supply, taxes affect the entire asset position of the household. In the short run, an adjustment of hours in the second job may be the only option available to an individual in responding to a tax change. Thus, analyses based on after-tax wages may understate supply-side effects. To estimate these effects a tobit procedure is employed. The empirical results suggest a backward-bending supply curve over thet range of moonlighting hours. Data consist of a subsample of male blue-collar workers from the 1978 cross-section of the Panel study of Income Dynamics.     

The exceptional performance of exporters and labour market outcomes: evidence from Egyptian firms

ABSTRACT

This paper examines the manufacturing export market in Egypt after the Arab Spring using a novel firm-level census dataset from 2013. Export is very rare in Egypt. The conventional export premia are very high, except for total factor productivity. Exporters have stark effects on labour market outcomes, including wages, employment, demand for skilled and female workers, wage inequality, and job security. These findings have two important implications: (1) Manufacturing exports might be monopolized by large firms, and (2) promoting exports could improve labour market outcomes, especially for skilled and female workers.     

Time-Series Wage Differential in Taiwan: The Role of International Trade

Rising relative wages between skilled and unskilled workers in developed countries has been a popular subject of recent studies. This paper analyzes Taiwan, a semi-developed economy, where the relative wage reveals a declining trend since the mid-1980s. The authors study the role of international trade. A major point of departure is to distinguish the effects of net exports to OECD countries from those to non-OECD countries. The paper also differentiates the effects of net exports to China from those to non-OECD countries except China. It is found that net exports to the OECD countries raise the relative wage of skilled workers, whereas net exports to non-OECD countries and China diminish the relative wage. Moreover, the impacts of net exports to China are much larger than those to OECD and other non-OECD countries. The documented wage effects of international trade in this work diverge from what existing works have argued based on Heckscher–Ohlin theory.     

The role of supervisors in the determination of wages and wage gaps

This article considers labour market discrimination by supervisors as a potential contributor to racial and gender wage gaps. Empirical analysis reveals evidence that all workers, except Hispanic males, earn significantly higher hourly wages when working for a supervisor of the same race and sex as themselves. Furthermore, the results suggest that sex has a larger impact on wages than race for workers with white supervisors, while race has a larger impact on wages than sex for workers with minority supervisors. Based on past research, we theorize that the degree of labour discrimination workers face may also be dependent upon the location and size of the firm in which they are employed. However, decomposing the samples by firm location and size suggests that these two factors cannot adequately explain the observed matched supervisor–worker wage effects, which supports the notion that these wage effects are largely driven by factors other than supervisor discrimination.     

扩大内需、工资上涨与对外出口 ——来自中国228个城市的面板数据

本文利用2000—2011年我国228个城市的面板数据，考察扩大内需、工资上涨对我国出口贸易产生的影响。研究表明：内需的提高和工资的上涨不仅不会抑制出口，还能促进出口贸易的扩张，数据显示：内需提高1%会促进出口量扩张约0263%，这意味着在目前阶段，我国对外贸易中国内消费需求因素发挥了核心作用；同时工资上涨1%，促进出口增加0174%,这说明工资上涨有助于提高劳动生产率，进而促进出口贸易。在分区域的研究中发现，扩大内需以及工资上涨对东、中、西部地区的出口贸易均能产生正向的促进作用，但是这一作用存在明显的地区差异性,对中部地区的作用最强。同时吸收外商直接投资以及减少政府干预对出口有正向激励作用。     

Building the minimum wage: the distributional impact of Germany’s first sectoral minimum wage on wages and hours across different wage bargaining regimes

The first minimum wage in Germany was introduced in 1997 for blue-collar workers in sub-sectors of the construction industry. In the setting of a natural experiment, blue-collar workers in neighboring 4-digit industries and white-collar workers are used as control groups for differences-in-differences-in-differences estimation based on linked employer–employee data. Estimation results reveal a sizable positive impact on mean wages in East Germany, but no significant effect in West Germany. Size and significance of effects are neither homogeneous across wage regimes (individual vs. collective contracts) nor across the distribution. The patterns suggest a compression in the lower part of the wage distribution and spillover effects to wages where the minimum is not binding, even in West Germany, where the bite of the MW was low. No effects on hours of work or substitution between workers of different qualification levels are found.     

Trade and inequality in a directed search model with firm and worker heterogeneity

This paper integrates the insight that exporting firms are typically more productive and employ higher‐skilled workers into a directed search model of the labour market. The model generates a skill premium as well as residual wage inequality among identical workers. A trade liberalization increases the skill premium and likely increases residual inequality among high‐skilled workers. The calibrated model generates results consistent with the prior literature examining the effect of the Canada‐US Free Trade Agreement on the Canadian labour market: a significant decrease in employment in manufacturing, but only a small change in unemployment and wages.     

Trade,Wage Gaps,and Specific Human Capital Accumulation*

We develop a new framework for the analysis of the impact of trade liberalization on the wage structure and on welfare. Our model focuses on the decision of workers to accumulate firm‐specific skills, by “on‐the‐job” training, knowing that this means their future wages will have to be negotiated, and that the outcome of negotiation will depend on the profitability prospect of firms operating in a new trading environment. We show that trade liberalization may reduce the welfare of a developing country because of its adverse effect on skill accumulation. We also explore the effects of trade liberalization on the wage gap between skilled and unskilled workers.     

Trade, Wages and Unemployment in the Presence of Hiring and Firing Costs

This paper offers a new explanation of the recent Australian wage inequality and unemployment experience. Building on a standard international trade model, it is argued that trade affects wage inequality and unemployment through changes in the bargaining power of different groups of workers in the presence of hiring and firing costs. This allows previously puzzling aspects of the trends to be explained, including the inconsistency of the existing Stolper-Samuelson trade explanation with rising relative skilled wages at the same time as rising skilled labour intensity of production. Considering differences in labour market institutions, in particular hiring and firing costs and minimum wages, allows differences between the experiences of Australia, the USA and Europe to be explained.     

中美制造业双边贸易对美国相对工资差距的影响研究*

在新古典贸易理论一般均衡的框架之下,运用1997-2014年中美两国的投入产出、贸易和工资数据,本文定量考察了中美制造业产品的双边贸易同美国制造业相对工资差距的关系。结果发现,美国从中国的净进口对美国制造业非熟练劳动力和熟练劳动力相对工资差距扩大存在影响,但影响幅度较小,贸易并不是引起相对收入差距扩大的唯一原因。但随着中美双边制造业贸易的进一步发展,美中贸易对美国工资差距的影响可能越来越大,以保护非熟练劳动力为名对中国产品实施贸易限制的呼声将会更高。     

Wage inequality, technology, and trade

The recent widening of wage inequality has been attributed by some to skill-biased-technical-change and by others to trade liberalization. This paper examines the two explanations within a unified model and also presents a new modeling of skill-biased-technical-change, where skilled workers replace unskilled ones. As a result technology adoption is endogenous and does not occur in all countries. Hence, wages for both types of workers, trade patterns and also factor productivities in all countries are endogenously determined. The model sheds light on the relationship between technology and trade, on the reasons for global productivity differences and on the causes for the recent rise in wage inequality.     

Terms of trade and domestic distribution: Export-led growth with abundant labour

A general equilibrium macro model is constructed to explore effects of export-led growth policies on the terms of trade and the domestic distribution of a developing region with abundant labour. This region, the South, trades with another, the North; they have different technologies and supplies of factors. It is shown that under certain conditions of dualism in the production of goods and of abundant labour supply in the South, an increase in the volume of exports from the South may bring about a sustained worsening of the South's terms of trade with the North even if this increase in exports is due to a positive shift in demand from the North. This change in the terms of trade is accompanied by a sustained loss of purchasing power of wages within the South. These results take place in a Walrasian stable market. When technologies are more homogenous and labour less abundant, the results are reversed: increased exports will take place together with improvements in terms of trade and a tendency to equalise factor prices between the regions. The results argue for coordination of domestic and international policies with special attention to technologies and labour markets.     

Trade and technological explanations for changes in sectoral labour demand in OECD economies

This paper sets out to establish the main determinants of variations in the demand for aggregate labour in manufacturing and service sectors (22) for a cross-section of OECD countries (14). A relatively new panel data set is employed in the analysis, the OECD's International Sectoral Data Base. Preliminary analysis revealed that the ‘within’ sector variation in the wage share dominated overall variation for most countries and time periods. A separate dynamic model was thus generated to explain the ‘within’ sector variation in the wage share. This model contained real wages, output, the capital stock, technological change (total factor productivity) and trade (the imports to value-added ratio) as independent variables. In addition the wage level was also interacted with these explanatory variables on the presumption that skill is positively correlated with the level of wages. Because of the potential for simultaneity bias, estimation was conducted by IV and OLS. The main findings were that the capital stock and technological change were the main determinants of shifts in labour demand. While some countries reported the trade variable as significant its influence was only of slight importance in most cases. The interaction terms proved to be significant in a large number of countries. Some evidence was found that capital and technological were complementary with skill. Overall it was found that broad agreement existed across countries in the factors which influence labour demand despite considerable differences in the cross-country nature of labour market institutions.     

Holdups and Efficiency with Search Frictions

A natural holdup problem arises in a market with search frictions: Firms have to make a range of investments before finding their employees, and larger investments translate into higher wages. In particular, when wages are determined by ex post bargaining, the equilibrium is always inefficient: Recognizing that capital-intensive production relations have to pay higher wages, firms reduce their investments. This can only be prevented by removing all the bargaining power from the workers, but this, in turn, depresses wages below their social product and creates excessive entry of firms. In contrast to this benchmark, we show that efficiency is achieved when firms post wages and workers can direct their search toward more attractive offers. This efficiency result generalizes to an environment with imperfect information where workers only observe a few of the equilibrium wage offers. We show that the underlying reason for efficiency is not wage posting per se, but the ability of workers to direct their search toward more capital-intensive jobs.     

Globalization and inter‐industry wage differentials in China

This paper explores the relationship between globalization and inter‐industry wage differentials in China by using a two‐stage estimation approach. Taking advantage of a rich household survey dataset, this paper estimates the wage premium for each industry in the first stage conditional on individual worker and firm characteristics. Alternative measures of globalization are considered in the second stage: trade openness and capital openness. A disaggregation of trade into trade in final and intermediate goods shows that increases in import (export) shares of final goods reduce (increase) the wage premia significantly, whereas imports or exports of intermediate goods do not explain differences in industry wage premia. This finding is supported by stronger effects for final goods trade in coastal than noncoastal regions. Our results also show a positive relationship between capital openness and industrial wage premia, though this finding is less robust when potential endogeneity issues are allowed for.
