Export Activity,Firm Size and Wage Structure: Evidence from Taiwanese Manufacturing Firms*

This study adopts a semiparametric smooth coefficient model to evaluate the export–wage premiums, firm size–wage premiums, and the wage gap between skilled and unskilled labor. Particular focus is placed upon widespread evidence indicating that pay levels in ‘large’ and ‘export‐oriented’ firms are higher than in their ‘small’ and ‘domestic‐oriented’ counterparts. Applying the firm‐level data for Taiwanese manufacturing firms, we find a positive export–wage premium for skilled workers and a negative export–wage premium for unskilled workers. The hypothesis of a constant export premium across firm size is rejected. While most of the export–wage premiums for skilled labor can be attributed to the small and medium firms, the large exporting firms have a significant adverse effect on wages for unskilled labor. Moreover, our results suggest that the firm size–wage premiums for skilled workers are larger than those for unskilled workers. The wage gap between the two skill groups is also sensitive to size categories.     

The value-added tax reform and labor market outcomes: Firm-level evidence from China

The tax incentives designed to stimulate firm investment may have a large and unexpected impact on labor market outcomes. Using a comprehensive data set on Chinese manufacturing firms during the period 1998–2007 with a difference-in-differences approach, we examine the impact of the value-added tax reform in 2004 on the firm-level labor market outcomes. We find that firms in eligible industries and pilot regions (treated firms) enjoying lower costs of purchasing fixed assets under the reform tended to increase capital investment and reduce employment simultaneously relative to firms that did not have tax incentives (the control firms). Compared with the control firms, the treated firms became more capital intensive but had declines in labor share in value added and average wage. We also find that the employment adjustment is associated with increase in the share of skilled workers in terms of engineers and technicians, but not workers with a college degree or higher.     

The wage impact of undocumented workers: Evidence from administrative data

Using administrative, individual level, longitudinal data from the state of Georgia, this article finds that rising shares of undocumented workers results in higher earnings for documented workers, but by a small amount. A one percentage point increase in the share of undocumented workers in a documented worker's county/industry results in an average wage boost of 0.44%. Within the firm, a one percentage point increase in the percent of undocumented workers employed by the firm boosts wages by 0.09% (0.11, 0.12, and 0.04 in low, medium, and high skill firms, respectively). Potential explanations for a positive wage impact are discussed.     

Role of Individual Social Capital in Wage Determination: Evidence from China

The present study examines the role of individual‐level social capital in workers’ wage determination in a Nash‐bargaining wage model using Chinese micro‐level data. The study finds a significant contribution of individual‐specific social capital to the wage level. In particular, larger individual social networks and workers’ positive attitudes toward social capital significantly increase the wage level. Moreover, the effect of social capital on the wage level is much larger for men than for women. The results indicate that construction of individual social capital could increase workers’ wages. However, efforts are needed to reduce the unequal contributions of social capital between men and women.

当前,受全球金融危机的影响,我国出现了近几十年来罕见的农民工回流现象。文章运用CES经济增长模型对新形势下农民工回流问题进行实证分析,发现城市产出水平、城市工资水平、资本价格、农村收入、农村劳动力外出打工付出的成本、城市失业劳动力总量等是影响农民工回流的主要因素,并提出了解决农民工回流问题的针对性措施。     

Imperfect competition,technical progress and capital accumulation

This paper constructs a dynamic equilibrium growth model, in which some firms act as monopsonies on the labor market. The framework is an overlapping generations growth model with altruistic agents. Two types of firms exist, competitive and non‐competitive, the latter being endowed with a more productive technology. They behave strategically on the labor market, in taking into account the impact of their demand for labor on the equilibrium wage and on their profit. In this framework, the impact of technical progress on capital accumulation can be positive or negative, depending on its effect on monopsony power.     

Firm Efficiency in Cambodia's Garment Industry on the Eve of the Multi‐Fiber Arrangement Termination

Applying a frontier analysis to 2004 firm‐level data, the present paper investigates firm efficiency and its determinants for Cambodia's garment industry. The study finds that firm experience and remuneration are crucial for improving scale efficiency and overall technical efficiency, while effective use of capital and adequate labor‐skill development are important for enhancing a firm's technical capabilities. Foreign‐owned enterprises with a relatively larger share of foreign labor outperform local firms. However, the present study does not reveal evidence of any advantages of a cluster‐type concentration in Phnom Penh and export markets, nor of any positive impacts of product specialization. The findings imply a need to support skill development for workers and local managers at the middle management level, and to streamline foreign direct investment measures to attract greater numbers of efficient foreign enterprises, so as to promote the development of the garment industry as a whole.     

最低工资制在完全与不完全市场中的影响——一个理论分析框架

本文通过构建一个包含产品市场和劳动力市场的模型,分析了最低工资制度在社会、经济等方面的影响,并得出以下结论:如果企业是市场工资率的被动接受者,则推行最低工资制度在促进劳动者福利提升的同时,会以减损社会总福利为代价,同时社会总产出水平下降;如果企业对市场工资率有影响能力,则通过最低工资制度提高就业者工资率水平,这不仅会促进劳动者福利的提升,同时也会造成社会总福利的改进,社会总产出水平上升。以此为基础,结合当前中国的社会实际,对于最低工资制度的实施提供了相关的政策建议。     

Long-Run Economic Performance and the Labor Market

This article uses a simple variation of the Solow model to study the interrelations between economic growth and the labor market. We show, both analytically and empirically, that income and capital per worker in the steady state depend positively on flexibility of the labor market; that the steady-state unemployment rate depends positively on the rate of population growth and the productivity growth rate and negatively on the savings rate and flexibility of the labor market; and, finally, that labor market flexibility affects convergence toward steady state.     

Trade liberalization and the wage gap: the role of vertical linkages and fixed costs

This paper studies the labor market impacts of trade liberalization, and specifically tariff reductions, with a focus on the wage gap between skilled and unskilled workers in presence of vertical linkages in the fixed costs of production. To that purpose, we develop and empirically test a monopolistic competition model with variable elasticity of substitution and labor differentiated by skill level, where skilled workers are the residual claimants of savings on imported inputs. Consistently with the model predictions, we find that a 10% reduction in tariffs implies on average a 3.8% increase in the wage gap. In addition, the same level of tariff reduction is expected to lower unskilled employment in domestic production by 3.3%, which is partially offset by an expansion of unskilled employment in the export segment of production. These results are obtained matching detailed international trade data with World Input–Output Tables and EU KLEMS data on country-sector wage by skill level on 17 OECD countries from 1996 to 2005.     

TECHNOLOGICAL CHANGE AND DEMAND FOR SKILLS IN DEVELOPING COUNTRIES: AN EMPIRICAL INVESTIGATION OF THE REPUBLIC OF KOREA'S CASE

There are few studies that directly address the upskilling issues in developing countries. Since theoretical analyses of these issues usually yield different results, upskilling in developing counties, and the factors of upskilling, if any, are rather empirical questions. This study shows that upskilling that occurs in developed countries in terms of the ratio of the number of white‐collar workers to that of blue‐collar workers also occurred in the Republic of Korea, one of developing countries. Increasing demand for highly‐skilled workers reflected in their employment and wage shares can be largely explained by “within industry’ shifts, not by “between industry” shifts, especially in the manufacturing industry. To further investigate the causes of these shifts, changes in white‐collar shares are regressed on the capital‐output and R&D‐sales ratio. Estimated coefficients are all positive, suggesting capital‐skill complementarities and skill‐biased technological change.     

Wage setting and tax progressivity in dynamic general equilibrium

This paper concerns the implications of progressive labor incometaxation for wage determination in dynamic general equilibrium.The main purpose is to analyze the general equilibrium effectsof increased tax progressivity in terms of the responses inthe real wage rate, employment, the capital stock, output andconsumption. Among the results, we find that increased tax progressivityincreases the real wage rate and decreases employment underboth union and competitive wage formation.     

Bertrand-Edgeworth equilibrium in a cash-in-advance economy

This paper is about price and wage competition in a dynamicgeneral equilibrium model. We consider an equity financed economywhere firms need money to finance their input costs. Part ofthe output is sold for money to be used in the next period asworking capital and the remaining part is distributed to ownersas real dividends. We first characterize the steady state competitiveequilibrium path. Second, we study whether this competitiveequilibrium can be supported as a pure strategy Nash equilibriumin price and wage setting games. We prove a positive resultfor price competition and a negative one for wage competition.     

Unemployment with trade and firm heterogeneity

By specifying the setting of the footloose capital model with firm heterogeneity, this paper examines the effects of trade liberalization on unemployment through two different mechanisms: firstly, we embed search frictions into the labor market; and secondly, we consider fair wages as the source of unemployment. In the model with search frictions, we find that both the expected wage and employment rate could be higher for a small country with better search technology. In the fair wage setting, the results show that an increase in trade freeness increases the unemployment rate of the large (small) country when the trade freeness is sufficiently high (low). Finally, we try to compare the welfare levels under different scenarios and discover that unemployment may lead to a deterioration in the welfare gains from trade.     

Do Exporting Firms Pay Higher Wages? Evidence from Kenya's Manufacturing Sector

Abstract: When trade liberalization was first embarked on in Kenya some 20 years ago, a key argument against it was that it would reduce domestic wages, as exporting firms sought to remain competitive versus, for example, the low‐cost Asian countries. A counter argument was that manufactured exports require more elaborate design, supervision, packaging and handling, and thus a more educated labor force than production for the domestic market. To attract such skills, exporting firms would need to pay higher wages than non‐exporting ones. This paper uses data from Kenyan manufacturing to study the impact of trade liberalization on earnings, distinguishing between exporting and non‐exporting firms. In particular, it investigates whether exporting firms paid a wage‐premium to their employees. The study uses manufacturing firm survey data from a World Bank regional project. The study has three important findings: (1) There was a large and significant effect of exporting on wages in the first decade of trade liberalization. During the first half of the 1990s, workers in exporting firms earned up to 30 percent more than those engaged in non‐exporting firms. The results are robust even after controlling for individual and firm‐level characteristics such as employee demographics, productivity, firm location and occupation. (2) After a decade of trade liberalization, exporting ceased to be a significant determinant of wages in Kenyan manufacturing, after controlling for productivity and firm location. (3) During the 2000s, casual or irregular employment became a more common feature of exporting firms. The results suggest that while higher wages were important in attracting skilled labor to exporting firms at the beginning of trade liberalization in the 1990s, domestic competition has since reduced the wage premium. Cost cutting pressures are instead reflected in the substitution of casual and low wage labor for permanent and better educated labor and in increased automation.     

Multinationals, skills, and wage elasticities

The increase in foreign direct investments raises concerns about labor market consequences in many countries. It is feared that multinational firms are inclined to shift jobs abroad and increase job volatility. We use firm-level data to examine if multinationality and foreign ownership affect the wage elasticity of labor demand. Unlike previous studies, we distinguish the effect on different skill groups of employees. We find no general difference in wage elasticity between foreign and domestic firms but the wage elasticity is higher in multinational firms than in national firms, in particular for medium-skilled workers.     

Demographic change,human capital,and economic growth in Korea

We construct a measure of human capital using micro datasets on labor composition of age, gender, education, and wage rate and analyze its role in economic growth for the Korean economy. Over the past three decades, human capital has grown steadily at about 1% per year, contrasting to a continuously declining trend of total work-hours. This growth has been driven by the rise of better-educated baby-boom cohorts. A growth accounting exercise shows that human capital contributes significantly to economic growth; it accounted for 0.5% points of annual GDP growth over the period. Human capital is projected to remain a major growth factor over the next two decades as the increase in educational attainment continues. Increased employment rate of elderly or female workers reduces the aggregate human capital growth while increasing the available labor. Polices to improve human capital of female or elderly workers help to increase aggregate human capital growth.     

Factor shares,inequality, and capital flows

I present an endogenous growth model where innovations are factor saving and model the choice of technologies in an Overlapping Generations framework. Markets are competitive and factor prices are determined by marginal productivity of factors; therefore, the income share of reproducible factors increases with the stage of development. Beyond the standard results of this type of model I find that (i) without bequests long‐run growth is not possible, (ii) if the economy presents long‐run growth then intrageneration inequality may last forever but if the economy does not present long‐run growth then in steady state, there is no intrageneration inequality, (iii) when the economy is open, the pattern of capital flows depends not only on the relative abundance of factors but also on the technologies and, for this reason, capital may not flow from rich to poor economies, and (iv) consistently, capital flows may not help to break poverty traps.     

How skilled were English agricultural labourers in the early nineteenth century?1

Using the wage accounts of two different farms in the 1830s and 1840s, matched with census records to determine the age of the workers, this article estimates age‐wage profiles for male and female agricultural labourers. Females earned less than males, and had less wage growth over their life cycles. Male wage profiles peaked at age 30–5, earlier than the wage profiles of workers today. Before the age of 30 wage growth was more rapid than increases in strength, but less rapid than wage growth among factory workers. If wage increases after the age of 20 indicate skill acquisition, then male agricultural labourers acquired a significant amount of skill, but less skill than contemporaneous factory workers.     

Labor Market Distortions in Côte d'Ivoire: Analyses of Employer‐Employee Data from the Manufacturing Sector*

Abstract: This paper investigates the extent and nature of distortions in the labor market in the Republic of Côte d'Ivoire by using quantile regression analysis on employer‐employee data from the manufacturing sector. We found that the labor markets in Côte d'Ivoire do not seem to be much distorted. Unions may influence employment through tenure but do not seem to influence wages directly except for vulnerable minorities that seem protected by unions. Establishment‐size wage effects are pronounced and highest for white‐collar workers. This may be explained by the efficiency wage theory, so that, even in the absence of unions, segmentation and inefficiencies will still be present as long as firms seek to retain their employees by paying wages above the market clearing level. The inefficiency arising from establishment‐size wage effects can be mitigated by education. Furthermore, the premium to education is found highly significantly positive only for higher education, and not for basic education, indicating that educational policies should also focus on higher education.
