Measuring human capital in the labor market: The supply of experience in 8 OECD countries

To investigate the evolution of the supply side of the labor market, I derive a methodology to measure an important component of the human capital level of the workforce, the experience of the labor market. Based on the perpetual inventory method, a stock of experience is estimated for eight OECD countries. It appears that, during the last three decades, the OECD labor markets have faced a decline in the supply of experience by the labor market participants, with a minimum in the early 1980s for most countries and a recovery in the 1990s. Some implications regarding relative wages, relative unemployment and schooling are discussed.     

Factor analysis of demand growth for information technology input in Japan

The purpose of this article is to decompose demand changes for factor input and explore the factor that information technology (IT) capital stock has largely increased in Japan. The Allen partial elasticities of substitution are calculated and the variations in factor input demand are broken down into two effects—price effect and output effect, using industry-level data. From an estimation of the total cost function, the following conclusions are presented. While IT capital stock and ordinary capital stock are complementary, IT serves as a substitute for labor. The factors influencing the high growth rate in IT capital stock are the decrease in the prices of IT and ordinary capital services, and the increase in the labor price, in addition to the output effect. On the other hand, labor demand declines due to both the downward rigidity of wages and the decrease in prices of two kinds of capital services.     

Changes in income distribution and welfare from greater immigration of unskilled workers

This paper considers the consequences of greater immigration of unskilled labor on income distribution and welfare in the receiving country. To address these issues, both the sending and receiving countries are represented in a static general equilibrium model which distinguishes between skilled and unskilled labor and which allows prices to be determined endogenously. In this framework an inflow of unskilled labor is likely to reduce wages of unskilled labor, but whether capital or skilled labor benefits depends upon demand elasticities, elasticities of substitution in production, and differences across countries in the productivity of unskilled labor. National welfare in the receiving country is likely to rise, to the extent that the relative price of importable goods falls, non-residents already in the country receive lower wages, immigrants receive lower wages than those paid to domestic workers, and immigrants cause little increased demand for public services and transfer programs.     

THE RELATIONSHIP BETWEEN CAPITAL STOCK, UNEMPLOYMENT AND WAGES IN NINE EMU COUNTRIES

The focus of this paper is to investigate the importance of the capital stock in the determination of wages and unemployment in a range of EMU countries and to compare the results across countries. A time‐series analysis is conducted in the case of nine euro area countries, which were selected solely on the basis of data availability and consistency: Austria, Belgium, Finland, France, Germany, Italy, Ireland, the Netherlands and Spain. The paper begins with a short review of the literature on capital stock and unemployment, before it deals with the theoretical model. This is followed by estimation and testing of the theoretical model put forward, using both time‐series and panel data. The results are supportive of the main hypothesis of the paper: capital stock is an important determinant of unemployment and wages in the countries considered for the purposes of the paper.     

Falling Labor Share and Rising Unemployment: Long–Run Consequences of Institutional Shocks?

The literature on unemployment has mostly focused on labor market issues while the impact of capital formation is largely neglected. Job creation is often thought to be a matter of encouraging more employment on a given capital stock. In contrast, this paper explicitly deals with the long–run consequences of institutional shocks on capital formation and employment. It is shown that the usual tradeoff between employment and wages disappears in the long run. In line with an appropriation model, the estimated values for the long–run elasticities of substitution between capital and labor for Germany and France are substantially greater than one.     

LABOR MARKET DISCRIMINATION AND CAPITAL: THE EFFECTS OF FAN DISCRIMINATION ON STADIUM AND ARENA CONSTRUCTION

We investigate the possibility that labor market discrimination affects capital. Previous research indicates that discrimination affects wages and employment in labor markets. However, the effects of discrimination on other inputs to production are not known. We develop a model of the optimal capital stock in the presence of customer discrimination and test this model using data on sports facility construction. The empirical evidence suggests that teams in cities with a larger white population and more racial segregation put less capital in place, confirming the predictions of the model about the effect of customer discrimination on capital inputs.

Union Wage Setting and Capital Income Taxation in Dynamic General Equilibrium

This paper concerns the effects of capital income taxation in a dynamic general equilibrium framework with union wage setting, when households face taxes related to both labor and capital. One purpose is to characterize the general equilibrium solution. Another is to study the effects of increased capital income taxation – in terms of the responses in real wages, employment, capital stock, output and consumption – and relate these behavioral responses to the overall tax structure. We also derive a cost–benefit rule for the purpose of analyzing the welfare effects of a small shift from labor income taxation to capital income taxation.     

The Distributional and Allocative Impacts of Virtual Labor Mobility across Time Zones through Communication Networks

Using a specific‐factors' model, with two goods (a shift‐working good and a non‐shift‐working good), three factors (capital specific to shift‐working, land specific to non‐shift‐working and labor) and two countries (Home and Foreign), which are located in different time zones, we highlight the impact of trade in labor services via communication networks on factor prices and production patterns. If two countries are identical in size, then under free trade in labor services, all workers work only in their local daytime, and night shift in each country is performed by imported labor services supplied by residents of the other country in their local daytime. Night‐time wage becomes the same as daytime wage (a wage equalization result). Other factor prices are also equalized. In both countries, capital rental rate increases, while land rent decreases. However, if two countries are different in size, trade in labor services does not equalize wages: in the large country, wages for night‐shift workers are higher than daytime wages and some residents work at night; in the small country, daytime wages become higher than night‐time wages and no one works at night, and night‐shift work is done by imported labor services from the large country. Land rent in the small country decreases. Land rent in the large country may or may not decrease, but it is always higher than in the small country. Capital rental rates in both countries are equalized and increase.     

Labour market effects of public capital stock: evidence for the Spanish private sector

This paper provides a new rationale for the positive effect of public capital stock on employment and wages. We show that higher levels of public capital reduce wages along the wage equation and enhance employment due to the resulting larger elasticity of labour demand with respect to wages. The estimation of a structural model for the Spanish private sector reveals that this wage channel is empirically relevant. We use the estimated parameters to simulate the recent incidence of the ratio of public to private capital stock on the private sector economic performance. We find (i) sizeable effects on employment, capital stock and gross domestic product, and (ii) that the wage channel is particularly important for employment.     

Lifetime consumption and investment: Retirement and constrained borrowing

Retirement flexibility and inability to borrow against future labor income can significantly affect optimal consumption and investment. With voluntary retirement, there exists an optimal wealth-to-wage ratio threshold for retirement and human capital correlates negatively with the stock market even when wages have zero or slightly positive market risk exposure. Consequently, investors optimally invest more in the stock market than without retirement flexibility. Both consumption and portfolio choice jump at the endogenous retirement date. The inability to borrow limits hedging and reduces the value of labor income, the wealth-to-wage ratio threshold for retirement, and the stock investment.     

Teaching Competition in Professional Sports Leagues

Popular wisdom in affluent countries holds that low wages in poor countries are a magnet for foreign investment, creating public anxiety about the potential threat to domestic employment and wages of capital flight. Historical evidence is provided to show that cheap foreign labor had little effect on foreign investment and the long-term economic performance of today's developed countries.     

The Choice of Technology and Equilibrium Wage Rigidity

In this general equilibrium model, firms engage in oligopolistic competition and choose increasing returns technologies to maximize profits. Capital and labor are the two factors of production. The existence of efficiency wages leads to unemployment. The model is able to explain some interesting observations of the labor market. First, even though there is neither long-term labor contract nor costs of wage adjustment, wage rigidity is an equilibrium phenomenon: an increase in the exogenous job separation rate, the size of the population, the cost of exerting effort, and the probability that shirking is detected will not change the equilibrium wage rate. Second, the equilibrium wage rate increases with the level of capital stock. Third, a higher level of capital stock does not necessarily reduce the unemployment rate. That is, there is no monotonic relationship between capital accumulation and the unemployment rate.     

Nonlinear prices and welfare

The paper constructs a general equilibrium model of education which is distinguished by a ‘job ladder’ or sticky wages, combined with the assumption that educated labor is preferred over uneducated labor, i.e. per a ‘fairness-in-hiring’ rule, when there is excess demand for jobs at given wages. This theory of education, considered to be relevant to liberal arts education in underdeveloped countries, is contrasted with the human capital doctrine and the Arrow-Spence screening theories. The analysis is mainly focused on examining the social inefficiency properties of the educational process captured in the model constructed.

General Equilibrium Tragedy of the Commons

Many poor economies depend on open access resources for their livelihoods. Households in resource-based economies allocate their time and other factors between resource extraction and other activities. As a result, factors may shift from one sector to another as marginal returns change. This has two important implications. First, it implies potentially strong linkages between resource and non-resource sectors. Second, it means that unmanaged resources cause inefficient allocations of inputs across all sectors, and the effects of resource management spill into other sectors. We construct a local general equilibrium model that accounts for inputs that over-allocate to an open access resource and create a general equilibrium tragedy of the commons. This model describes resource rent dissipation more adequately in economies with mobile factors than a model with slowly dissipating rents. Perfectly mobile factors dissipate rent in every period, but endogenous wages cause labor and capital allocations to change with the resource stock. We use the model to illustrate medium-run impacts of a limit on capital in an artisanal fishery in Honduras. Simulation results reveal that fishery management has economy-wide impacts on prices and wages. Managers in developing countries thus should consider these linkages when implementing policies to conserve fish stocks.     

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.     

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.     

Disinflation and the supply side

This paper studies the dynamics associated with permanent and temporary reductions in the devaluation rate. The analysis uses an intertemporal optimizing model of a small open economy with imperfect capital markets and endogenous labor supply. With a constant capital stock, the model predicts an initial reduction in real wages and an expansion in output. Consumption falls on impact but increases afterward. In addition, with a temporary shock, a current account deficit emerges and a recession sets in at a later stage. With endogenous capital accumulation, numerical simulations show that the model is also capable of predicting a boom in investment.     

Growth with many agents and wages paid ex ante

In this paper, we consider a one-sector model of economic growth with several infinitely-lived heterogeneous agents, who are endowed with diverse discount factors as well as preferences over consumption. In line with the classical Ramsey model, agents are not allowed to borrow against future income. Unlike the traditional assumption of ex post wage payment, wages are paid ex ante in our model. We first explain the difference between the assumptions of wages being paid ex ante and wages being paid ex post in the framework of a simple illustrative two-class model. Our main result shows that in contrast to the many-agent Ramsey model with ex post wage payment, the capital stock sequence converges to the steady state stock irrespective of production technology employed by the firms. Further, all impatient agents own zero capital stock, whereas the most patient agent owns the entire capital stock from some time onward. Thus, we have shown that a slight modification in the timing of wage payment in growth models can lead to significant changes in the stability properties of equilibrium dynamics.     

美貌溢价:劳动力市场歧视是主因吗?—基于中国劳动力动态调查数据的实证研究

文章利用中国劳动力动态调查(CLDS)数据,分析了具有不同身高等外貌特征的劳动力的工资差异及其来源.分解结果显示,较高男性的高收入几乎全部可以用人力资本、社会交际及其他劳动能力特征差异来解释,劳动力市场歧视等不可解释部分非常小.较矮男性的低收入有60%可以用劳动能力特征差异来解释,有40%属于劳动力市场歧视等不可解释部分.身高较高(矮)的女性的高(低)收入也主要源于劳动能力特征差异;对较矮女性来说,歧视等不可解释部分具有相反的影响,即劳动力市场不但不歧视反而偏爱较矮的女性.因此,劳动力市场歧视并不是身高溢价的主要原因.然而,劳动力市场之外,在社交活动中的外貌歧视会通过增加社交网络差异而提高美貌溢价.
