Skill Upgrading and the Real Exchange Rate

This paper examines the effect of changes in the real exchange rate on skill upgrading in the case of Chile. Using plant‐level data from the manufacturing sector, we find that a real depreciation increases the share of skilled workers in the total wage bill in exporters but not in non‐exporters. This result suggests that depreciations or, more generally, increases in export profitability, may induce exporters to adopt more skill‐intensive technologies. This finding gives support to recent models of trade that highlight the possible effect of the real exchange rate on skill upgrading and wage inequality. This paper also finds that real depreciations increase plants’ export intensity, suggesting that skill upgrading for firms that are already exporters is the channel through which real exchange depreciations affect wage inequality.     

转型期资本投资、产业结构、市场化对中国就业效应的实证研究

本文通过对投资、技术进步、市场化程度、产业结构变动、实际工资等因素对我国就业量的影响进行的实证分析和检验结果显示,自20世纪90年代以来,资本投资增加、产业结构变动及实际工资上涨是拉动就业增加的主要因素,市场化程度提高则抑制了就业量的增加.但随着时间的推移,资本投资、产业结构变动对就业的贡献度逐渐下降,工资增长对就业的拉动作用逐渐增强,市场化对就业的抑制作用逐渐减弱.     

Trade patterns,unemployment and growth

This paper analyses the implications of a minimum wage in an open economy two-sector model where the effect of growth on trade and unemployment is explicitly determined. The first-best policy is a wage subsidy to all employment while the second-best policy is a production tax cum subsidy. In the absence of policy intervention it is shown that growth in the short run results in decreasing unemployment for the home country if it is specialized in consumption goods or incompletely specialized provided that the minimum wage is binding. If the economy is specialized in investment goods, then unemployment may increase initially but as growth continues the minimum wage no longer remains binding and full employment is restored. In the long run by examining the dynamic interaction between trade and growth it is possible for the economy to be incompletely specialized with unemployment. If the economy specializes in consumption goods, it is possible for the economy to attain full employment.     

Real Wages,Business Cycles and New Production Patterns

In contrast with most conventional business cycle models, empirical data show no clear correlation between real wage movements and output and employment. This paper presents a model, largely based on concepts presented by Joseph Schumpeter,in which economic growth and the business cycle are triggered by endogenous real shocks to technology. It suggests that the speed and magnitude by which technological shocks spread throughout the economy determine whether the resulting changes in real wages will be pro-or counter-cyclical.     

The NAIRU,Aggregate Demand and Investment

The nature of the non‐accelerating inflation rate of unemployment (NAIRU) is analysed. The focus of our analysis is the role of aggregate demand and capacity in the context of the NAIRU. Two aspects of the relationship between the level of aggregate demand and the NAIRU are of particular significance. First, it is argued that the real wage–employment relationship based on enterprise decisions cannot be fully articulated without reference to the level of aggregate demand. Second, a model which allows for variable returns to labour and the notion of full capacity is used to explore the effects of shifts in the capital stock on the real wage–employment relationship. The model is specifically used to explore whether a sufficiently expansionary environment can generate sufficient investment to shift that relationship until the NAIRU is compatible with full employment. A number of limitations on the conclusions reached are considered, and the policy implications are briefly considered.     

Public pollution abatement and wage inequality

This paper constructs three-sector general equilibrium models to investigate how public pollution abatement affects the skilled–unskilled wage inequality. In the basic model with full employment, we find that a higher degree of public pollution abatement will decrease the wage inequality if the intensity of skilled labor in the urban skilled sector is sufficiently large and expand or narrow down the wage gap if this intensity is sufficiently small. In the extended models, we consider other four cases, and obtain the results similar or dissimilar to that of the basic model.     

Impact of Trade on Canada's Employment,Skill and Wage Structure

Using newly constructed data for 88 Canadian industries (including primary, manufacturing and services), for 15 years (1992–2007), we analyse the impact of trade and technological change on labour demand, skill structure, wage premiums and welfare in Canada. Results show that export growth has no impact, whereas import growth reduces employment growth. But contrary to popular belief, Canada's job loss due to imports has been very small, only about 6,000 persons annually. China's negative impacts are more pronounced in industries where the share of information and communication technology (ICT) capital is rising fast and among low R&D intensive industries. In terms of skill change, ICT use and real exchange rate appreciation are biased towards high skill workers. Imports from the United States and China are skill‐neutral, whereas imports from Mexico are skill‐upgrading. Overall, neither export nor import growth has an impact on the wage rate. However, had there been no imports from China, the annual wage growth rate of high skill manufacturing workers would have been 0.6 per cent higher. Between 1992 and 2007, there was an annual net gain from the rise in imports at about 0.4 per cent of GDP, in addition to the gains obtained from 1992 import levels vis‐à‐vis autarky.     

International competition, downsizing and wage inequality

A country with Cournot competition and free entry experiences an increase of its market size either due to economic growth or international integration of its goods markets. This implied increase in competition leads to shrinking mark-ups and forces firms to reduce overhead costs relative to output. This implies a reallocation at the aggregate level from administrative to productive activities. Relative factor rewards change and wage inequality increases. The factor which loses in relative terms can even lose in real terms. From a quantitative perspective, international competition is demonstrated to be the more plausible cause of rising wage inequality.     

Fairness,trade, and inequality

We develop a model of international trade between two symmetric countries that features inter-group inequality between managers and workers, and also intra-group inequality within each of those two groups. Individuals are heterogeneous with respect to their managerial ability, and firms run by more able managers have a higher productivity level and make higher profits. There is rent sharing at the firm level due to fair wage preferences of workers, and hence firms with higher profits pay higher wages in equilibrium in order to elicit their workers' full effort. We show that in this framework international trade leads to a self-selection of the best firms into export status, with exporting firms having to pay a wage premium. Aggregate welfare increases, but there is also larger inequality along multiple dimensions: Involuntary unemployment and income inequality between managers and workers increase, and so does inequality within these two subgroups of individuals, as measured by the respective Gini coefficients.     

Real exchange rates,dollarization and industrial employment in Latin America

We use a panel dataset on industrial employment and trade for 9 Latin American countries for which liability dollarization data at the industrial level is available. We test whether real exchange rate fluctuations have a significant impact on employment, and analyse whether the impact varies with the degree of trade openness and liability dollarization. Econometric evidence supports the view that real exchange rate depreciations can impact employment growth positively, but this effect is reversed as liability dollarization increases. In industries with high liability dollarization, the overall impact of a real exchange rate depreciation can be negative.     

Trade,growth and wage inequality in Bangladesh

Abstract

Using model selection techniques based on out-of-sample predictive ability criterion in a Vector Autoregression (VAR) framework, this paper empirically examines the causal relations among growth, trade, and wage inequality in Bangladesh between 1971 and 2000. There is some evidence of bi-directional causality between growth and inequality and between trade and growth. That growth causes trade and that trade causes inequality are robust results. Furthermore, evidence strongly suggests that investment is important for trade, and the terms of trade between agricultural products and manufacturing products is an important causal determinant of both growth and trade.     

Macroeconomic stability in a flexible labor market

This paper examines the relationship between labor market flexibility and macroeconomic stability from a post‐Keynesian perspective. Considering two aspects of labor market flexibility, employment flexibility and real wage flexibility, I adopt the flex–output model to discuss employment flexibility and extend it by incorporating real wage dynamics induced from a wage–price Phillips curve to discuss real wage flexibility. Simulation of the model suggests that employment flexibility possibly increases instability of an economy whereas real wage flexibility reduces it.     

Labour market institutions,learning and self-employment

We develop a dynamic partial-equilibrium model to analyse how labour market institutions (wage compression, minimum wages, unemployment benefits, mobility costs and fixed-costs of self-employment) and learning affect who and when people become self-employed. We find that certain ability groups of workers become self-employed for both “carrot” and “stick” reasons: Some prefer self-employment to the low institutionalised wage, while others are not productive enough to qualify for a job at the institutionalised wage. Furthermore, wage compression and learning may give rise to a class of switchers who start in wage employment and later switch to self-employment. Several predictions of the model are consistent with observed empirical regularities, such as the existence of a group of low-skilled self-employed workers, the increasing propensity for self-employment over age groups and the larger spread in earnings among self-employed.     

Trade liberalization and rising wage inequality in Latin America: Reconciliation with HOS theory

The paper puts forward the hypothesis that the transitory effects of trade liberalization on wage inequality can differ from the long-run outcome. In cases where the HOS theory predicts a decline in wage inequality in the long run, a temporary rise can, nevertheless, occur due to (i) the asymmetries in the speed of contraction in the import sector and expansion in other sectors, and (ii) the capital-skill complementarity in production. The asymmetric contraction and expansion causes a transitory capital accumulation that boosts the relative and the real wage of skilled labor due to capital-skill complementarity. Although the long-run HOS fundamentals are, therefore, dominated in the short run by the transient effects arising due to capital-skill complementarity, the observed rise in wage inequality is nonetheless consistent with the HOS theory appropriately extended to a dynamic setting.     

Economic liberalisation,gender wage inequality and welfare

The article develops a 3-sector general equilibrium model appropriate for economies with female labour oriented export sector to examine the effects of economic liberalisation policies on gender based wage inequality. It is assumed that there exist disparities in efficiencies between male and female labour due to skewed access to education and health, and differences in their spending patterns leading to differential effects of respective wages on their nutrition. The results indicate that tariff cut may reduce gender wage inequality, but may have detrimental effects on welfare; while foreign capital inflow may accentuate the inequality, despite improving the welfare of the economy. However, government policies to increase the provision of education and health have favourable effects on gender wage inequality but may be welfare deteriorating. Thus, the article provides a theoretical explanation to empirical evidences of diverse effects of liberalisation on gender wage inequality and explains the possibility of a trade-off between gender inequality and social welfare.     

Fair wages, unemployment and technological change in a global economy

This paper analyzes the effects of global and national technological change on employment and relative wages in an integrated two-country world (“Europe” and “America”), where both countries are characterized by equilibrium unemployment due to fair wage constraints. The asymmetry between the countries arises from country-specific preferences towards wage inequality, with Europe's preferences being more egalitarian. Furthermore, we look at integration between this two-country world and a third country (“low-wage south”). We derive an analytical tool, the Virtual Integrated Equilibrium, that allows us to adapt Dixit and Norman's Integrated Equilibrium approach to a situation where both countries have endogenous unemployment levels.     

The Effect of the Chinese Economy on Mexican Maquiladora Employment

During the last five years the maquiladora industry of Mexico has seen a slowing of the rapid growth experienced during the 1990s. The maquiladora expansion has been linked to U.S. foreign direct investment. Additionally, China has become a major receptor of U.S. investment for the production and export of manufacturing goods. This study estimates the impact of the industrial activity of the United States and China on employment demand in the maquiladora industry of the northern border states of Mexico. Using data on industrial activity, real hourly wages, and the real exchange rate as a proxy of Mexican competitiveness, a bounds test cointegration analysis is developed. The results show that the variables affecting external demand have impacted the maquiladora employment trend negatively, while wage differentials and the exchange rate tend to encourage maquiladora activity.     

Analyzing the Link Between Real GDP and Employment: An Industry Sector Approach

This paper offers insight into the “jobless recovery” phenomenon recently experienced in the U.S. economy by examining industry-sector employment responsiveness to the long-term real GDP expansion occurring during 1991- 2001. Two employment models are specified—one using real GDP as the only explanatory variable and the other using real GDP, five additional macroeconomic performance variables, and a time trend as explanatory variables. Monthly data for April 1991–March 2001, and OLSQ regressions are used to derive industry-sector elasticities of employment with respect to real GDP. Empirical results highlight the importance of controlling for non-real GDP macro variables when determining relationships between employment and real GDP. The results identify five industries exhibiting “jobless recovery” characteristics (having negative employment elasticities) and a broad range of employment elasticities across industry categories. The findings may be helpful to business economists modeling their own industry employment and suggest that even during extended periods of real GDP expansion, there may be a case for using industry-specific labor market transition initiatives to assist employment growth.

THE DOUBLE ROLE OF SKILLED LABOR,NEW TECHNOLOGIES AND WAGE INEQUALITY

We examine the relationship between the supply of skilled labor, technological change and relative wages. In accounting for the role of skilled labor in both production activities and productivity‐ enhancing ‘support’ activities we derive the following results. First, an increase in the supply of skilled labor raises the employment share of non‐production labor within firms, without lowering relative wages. Second, new technologies raise wage inequality only in so far as they give incentives to firms to reallocate skilled labor towards non‐production activities. In contrast, skill‐biased technological change of the sort usually considered in the literature does not affect wage inequality.     

Viability and Corridor Stability in Keynesian Supply‐Driven Growth

In this paper we reconsider and generalize a two‐dimensional growth cycle model of Skott that is based on supply‐side adjustment mechanisms and a Kaldorian theory of income distribution. This model gives rise to degenerate Hopf bifurcations if behaviour (in terms of rates of growth) is linear close to the steady state. Furthermore full capacity limits lead to viable dynamics from the global point of view if the steady state is locally attracting and to corridor stability with persistent fluctuations when it is repelling. These findings can to some extent also be obtained for a three‐dimensional growth cycle extension of the Skott model, which includes real wage dynamics as in Rose's employment cycle, now turned into economically viable dynamics through appropriate non‐linearities in the assumed adjustment processes of output and prices in the case when the steady state is locally repelling.
