Estimating the Heckscher–Ohlin model: Inverting the inverse matrix

This paper estimates the Heckscher–Ohlin model with annual US data from 1949 to 2006 for outputs of manufactures and services with inputs of fixed capital assets and the labor force. Difference equation and error correction regressions provide estimated coefficients for the comparative static system. Tariffs on manufactures primarily raise the capital return in the estimated Stolper–Samuelson results. Factor price equalization does not hold for labor and capital. Inverting the estimated system inverse matrix provides evidence on production. The suggestions are capital biased production of manufactures, strong substitution of capital for labor, and strong labor substitution in manufactures.     

不同所有制企业的工资决定机制考察

本文通过1989—1997年教育回报率在不同所有制间的差异及其变化来考察中国的劳动力市场。利用CHNS数据分别估计国有企业、大型集体企业、小型集体企业以及私营企业的工资方程,结果表明教育回报率在民营部门增加得较为明显,在其他部门则没有增加的迹象。1997年,民营部门教育回报率明显高于其他部门,样本选择只能解释其中一部分差异,这表明民营经济工资决定机制与其他部门不同。     

A MODEL OF GENERAL TRAINING, BANKING, AND LABOR TURNOVER

Conventionally, models of general training assume perfect capital markets; as a result, workers smooth their consumption stream through borrowing. In these models general training has no effect on labor turnover. I develop a model of general training where workers have diminishing marginal utility from consumption, capital markets are imperfect, and a firm cannot monitor the match quality with another firm of a worker who quits. It is shown that in the absence of a surplus effect from training, raising the level of general training steepens the worker's wage profile for reasons associated with consumption smoothing and labor turnover. However, with the surplus effect, results may be ambiguous.     

RETURN TO WINE: A COMPARISON OF THE HEDONIC,REPEAT SALES AND HYBRID APPROACHES

Comparisons between the return to wine and standard financial assets are complicated in that the return to wine must be estimated from infrequent sales of heterogeneous wine brands. Wine returns can be estimated using several different methods, and here the performance of the hedonic model, repeat sales model, and hybrid model are compared using 14,102 auction sale observations for Australian wine over the period 1988 to 2000. The results show that the hybrid model provides the most efficient estimates, and that the repeat sales model provides significantly higher total return estimates than the other two models.     

Schooling, Training, Growth and Minimum Wages

We examine how the long-run growth performance of an economy is affected by a labor market distortion. In our model, growth occurs through skill formation, and skills are generated through schooling and training of unskilled workers. We analyze how a minimum wage legislation affects long-run growth. In general, the effects are ambiguous. The reason is that while a minimum wage discourages training, it also encourages schooling. The net effect then depends on whether training or schooling dominates the long-run increases in labor productivity.

Nonlinearity in dynamic adjustment: Semiparametric estimation of panel labor supply

We estimate a semiparametric dynamic panel data model by the local linear kernel method and we interpret the slope of the nonparametric component function as a varying slope coefficient. Thus, the slope coefficient is a smooth, but otherwise unknown, function of some of the regressors. A Monte Carlo experiment is reported to examine the finite sample performance of the local linear estimator. We apply the estimation method to a labor supply equation for men from the triannual Survey of Income and Program Participation (SIPP). Specification tests based on the estimated labor supply elasticities, partial adjustment coefficients, and residuals demonstrate the improvements from a semiparametric partially linear model. Our empirical results point to a need by economists to revisit the issue of the speed of labor market adjustment to policy induced shifts in labor demand and to take more formal econometric account of heterogeneity in wage effects when studying the distributional consequences of tax reforms for labor supply earnings.

Employment polarization and the role of the apprenticeship system

This paper studies the effect of apprenticeship training on technology adoption and labor market polarization. A stylized model with two key features is developed: (1) apprentices are more productive due to industry-specific training, but (2) from the firm׳s perspective, when training apprentices, technological innovation is costly since training becomes obsolete. Thus, apprentices correlate with slower adoption of skill-replacing technologies, but also less employment polarization. We test this hypothesis on German regions given local variation in apprenticeship systems until 1976. The results show little computer adoption and no employment polarization related to apprentices, but similar displacement of non-apprentices by computers as in the US.     

Schooling, Informal Experience, and Formal Sector Earnings: A Study of Indian Workers

This paper estimates an earnings function for male workers belonging to the Indian corporate sector. The model allows for differential rates of return to schooling and distinguishes tenure from total labor market experience. The rate of return to schooling is found to be low up to the junior level, increases significantly at the secondary and undergraduate levels, but sharply declines at the masters level. Seniority and firm-specific factors are found to be important determinants of earnings. When years of unemployment and informal experience are incorporated, earnings of low-education workers appear to be driven entirely by formal-sector experience.     

Income Distribution,Econophysics and Piketty

Piketty, Atkinson and Saez have put the analysis of income distribution back on center stage. The distinction between property income and labor income plays a central role in this framework. Property income derives from the rate of return on stocks of income-earning wealth and is more unequally distributed than labor income. Piketty argues that, because the rate of return (r) is generally greater than the rate of growth of the economy (g), property income tends to grow more rapidly than labor income, so that rising income inequality is an intrinsic tendency of capitalism despite interruptions due to world wars and great depressions. This article argues the exact opposite. The rise of unions and the welfare state were the fruits of long-term historical gains made by labor, and the postwar constraints on real and financial capital arose in sensible reaction to the Great Depression. The ‘neoliberal’ era beginning in the 1980s significantly rolled back all of these. The article uses the econophysics two-class argument of Yakovenko to show that we can explain the empirical degree of inequality using two factors alone: the profit share and the degree of financialization of income. The rise of inequality in the neoliberal era then derives from a reduction in the wage share (rise in the profit share) in the face of assaults on labor and the welfare state, and a sharp increase in the financialization of incomes as financial controls are weakened. These are inherently socio-political outcomes, and what was lost can be regained. Hence, there is no inevitable return to Piketty’s ‘patrimonial capitalism’.     

The returns to education and wage penalty from overeducation: New evidence from Vietnam

This study intends to estimate the rate of returns to education in Vietnam, the distributive effects of education on wages, and the wage penalty from the incidence of overeducation in the Vietnamese labor market during 2004–2016. This study employs a pseudo-panel approach to address omitted variables bias and the unconditional quantile regression to identify the heterogeneity of returns to education across the income distribution. Our main finding indicates that the estimated rate of returns to education in Vietnam is approximately 6.5%, showing a downward bias from previous estimates. The returns vary across wage distributions, where a lower rate of return is observed in lower quantiles and a higher rate among those individuals at the higher quantiles. The returns to education have declined since 2008, confirming the oversupply of highly educated workers in the Vietnamese labor market with an estimated wage penalty of 17%. Government assistance measures are needed to reduce the overeducation and the wage penalty issues in the Vietnamese labor market.     

The Social Return to Apprenticeship Training

This paper draws together findings from a recent program of research to estimate the social rate of return to apprenticeship training and how the costs of training are distributed. It is estimated that 53 per cent of the costs of training an apprentice are borne by the employer, 28 per cent by the public sector and 19 per cent by the apprentice. This is in sharp contrast to the prediction of economic theory that trainees pay for general training. The social rate of return to male apprenticeships is estimated to be 12.8 per cent. This is in line with previous estimates of the social rate of return to university degrees and supports the case for policy measures to increase the level of apprenticeship training. Reforms taking place under the New Apprenticeships Systems are intended to shift the distribution of costs in line with that predicted by theory by placing a greater cost burden on apprentices for general training and increasing the specificity of training. If employers' willingness to offer apprenticeships has been a constraint, then these changes should stimulate apprenticeship training.     

The wage effects of training in Portugal: differences across skill groups,genders, sectors and training types

This article investigates the determinants and wage effects of training in Portugal. In a first stage, we show that there are considerable differences in training participation across groups of workers, with elder and low educated individuals participating substantially less. In a second stage, we show that training has a positive and significant impact on wages. The estimated wage return is about 30% for men and 38% for women. Discriminating between levels of education and working experience and the public and private sector reveals important differences across categories of workers. We find that women, low educated workers and workers with long working experience earn larger returns from training. The average effect of training is similar in the private sector and the public sector. However, differences across experience groups are larger in the private sector, while differences across education groups are larger in the public sector. We use three alternative classifications of training activities and find that training in the firm, training aimed to improve skills needed at the current job and training with duration less than a year are associated to larger wage gains.     

Educational choice, wage determination, and rates of return to education in Taiwan

This paper estimates educational choice, wage determination, and the rate of return to education in Taiwan using Taiwan's Manpower Utilization Survey data of 1996. As education investment is a self-selection process, this paper adopts a two-stage estimation method. First, a polychotomous ordered probit model is used to estimate the education decision. Second, the wage equations of different educational attainments are estimated by incorporating the possible selection bias obtained in the probit model. Finally, rates of return on each education level are calculated from the estimation results.     

A life-cycle model of outmigration and economic assimilation of immigrants in Germany

This paper estimates a forward-looking life-cycle model of outmigration and labor force participation. The estimated model is used to evaluate the impact of enforcing a maximum stay duration for newly admitted immigrants on labor force participation and outmigration. Restricting the migration duration is found to have little effect on the labor force participation of skilled immigrants, and a negative effect on that of unskilled immigrants. Restricting the migration duration is also found to encourage the departure of unskilled and unsuccessful immigrants before the maximum duration is reached. These results are obtained by estimating the model with data that contain no information on outmigration decisions. It is shown that the assumption of a continuous state variable affecting attrition only through outmigration allows the probability of outmigration to be identified from the panel attrition. This probability can then be estimated using standard dynamic programming techniques. The migration durations so estimated are found to differ substantially from those estimated under the assumption that immigrants are myopic decision makers.     

Import-Price Uncertainty, Production Decisions, and Relative Factor Shares

The effects of import-price uncertainty on factor income in Switzerland are estimated. The production-theory approach is used to derive the import demand function from an expected utility maximization problem, treating imports as an input to the technology. The model is also used to test for risk aversion and to assess the impact of uncertainty on the volume of imports and gross output. Evidence is found that, for most years, labor has been relatively more vulnerable to uncertainty than has capital.     

Multinational Firms, International Knowledge Flows, and Dual Labor Markets in Developing Economies

This paper seeks to explain how the expansion of multinational firms in a developing economy affects its labor market variables, such as wages in indigenous firms, the average wage level and total employment. Three potential effects: the transfer of foreign knowledge and the associated technological change, diffusion of this knowledge among indigenous firms, and the inflow of the physical capital from abroad, are examined under two possible scenarios: fixed and unlimited labor supply. The results obtained depend on the organization of the labor market in the host country, differences in capital intensity between multinational and local sectors, the amount of physical capital transferred to the host country from abroad, as well as the magnitude of knowledge spillovers stemming from multinational activity to indigenous firms. The predictions of the model are more consistent with empirical observations reported in empirical studies than those of other theoretical studies existing in the literature.     

Scale-dependent and risky returns to savings: Consequences for optimal capital taxation

I present a model of optimal capital taxation where agents with heterogeneous labor productivity randomly draw their rate of return to savings. Because of scale dependence, the distribution of rates of returns can depend on the amount saved. Uncertainty in returns to savings yields an insurance rationale for taxing capital on top of labor income. I first show that, because of scale dependence, agents making the same saving decision should access the same rate of return at the optimum. I then constrain the information set of the government and show that, as soon as return are uncertain, positive capital income taxation is needed at the optimum. The optimal linear tax on capital income trades off insurance with distortions to both savings and to the rate of return in a context of scale dependence. Eventually, I argue that scale dependence in and of itself is not sufficient to justify capital taxation on top of labor income taxes. These results are still valid when agents can optimize between a risk-free and a risky-asset that can both exhibit scale dependence.     

Wage–productivity differentials and Indian economic efficiency

A frontier-general equilibrium analysis with skill transformation evaluates the productivities of skilled and unskilled labor and potential of the Indian economy. We compare the wages of skilled and unskilled labor between 1994 and 2002 with their respective productivities over this period. Education is considered to be responsible for the skill formation over this period: the change in skilled labor supply is endogenous in the model. Compared to its productivity, skilled labor is underpaid in the initial period and overpaid in the second period. Unskilled labor is underpaid in both periods. A decomposition exercise shows that skilled labor gains from free trade, and stands to lose due to education and domestic competition in the second period. The annualized rate of return to education is between 7 and 10%. The economy operates below its potential in both periods, particularly in the second—due to trade limitations and the failure to capture the return to education. Service sectors are found to have potential to grow significantly.     

Supply,wealth effects,negative multipliers,and stability

This paper is concerned with the Blinder-Solow contention that negative government expenditures multipliers are trivial inasmuch as the resulting equilibrium is unstable in a conventional IS-LM model with constant prices. An aggregate supply side, which features progressive taxation of labor income and a real balances effect in the labor supply equation, is added to the model, and it is shown that negative multipliers are not necessarily inconsistent with local asympototic stability.     

International factor mobility and the labor market: A macroeconometric analysis of the German labor market

This paper deals with some problems of international factor mobility with respect to labor using the case of the German labor market. A quarterly macroeconometric model of the German labor market is developed and estimated. It consists of equations explaining labor supply and demand for men and women. Most equations distinguish between labor measured in persons and hours. After a determination of the variables of this model which are influenced by foreign employment two groups of foreign workers which differ according to their EC-member status are discussed separately. Because of several legal and institutional regulations a different treatment of each group with respect to employment policy is necessary. For foreigners from outside the EC alternative reaction functions of the government are discussed and estimated. As the officially published unemployment rate is not comparable intertemporally because of foreign involuntary remigration during recession a new unemployment series including these persons is constructed and explained. The influence of foreign employment on wages is examined and two wage equations are estimated. Finally, some simulation results of an enforced remigration policy are reported.
