We develop a dynamic, general equilibrium non‐scale endogenous growth model of North–South technological‐knowledge diffusion by imitation. Countries differ in levels of exogenous productivity, human‐capital levels and R&D capacity. Growth is driven by Northern innovative R&D and the South converges towards the North. Growth is also driven by human‐capital accumulation, scale effects are removed, imitation is only feasible once a threshold distance to the frontier has been attained and is dependent on the South's relative level of employed human capital and on domestic policies promoting R&D. Imitation promotes partial convergence of inter‐country wages and governs the path of intra‐South wage inequality. 相似文献

We investigate the role of education on worker productivity and firms' total factor productivity using a panel of firm-level data from China. We estimate the returns to education by calculating the marginal productivity of workers of different education levels based on estimates of the firm-level production function. We also estimate how the education level of workers and CEO contributes to firms' total factor productivity. Estimated marginal products are much higher than wages, and the gap is larger for highly educated workers. Our estimate shows that an additional year of schooling raises marginal product by 30.1%, and that CEO's education increases TFP for foreign-invested firms. Estimates vary substantially across ownership classes, the effect of schooling on productivity being highest in foreign-invested firms. We infer that market mechanisms contribute to a more efficient use of human capital within firms. 相似文献

This paper develops a tractable, heterogeneous agents general equilibrium model where individuals have different endowments of the factors that complement the schooling process. The paper explores the relationship between inequality of opportunities, inequality of outcomes, and aggregate efficiency in human capital formation. Using numerical solutions we study how the endogenous variables of the model respond to two different interventions in the distribution of opportunities: a mean-preserving spread and a change in the support. The results suggest that a higher degree of inequality of opportunities is associated with lower average level of human capital, a lower fraction of individuals investing in human capital, higher inequality in the distribution of human capital, and higher wage inequality. In particular, the model does not predict a trade-off between aggregate efficiency in human capital formation (as measured by the average level of human capital in the economy) and equality of opportunity. 相似文献

The accuracy of the match between a workers talents, skills, and capabilities and those required by his or her job has seldom been addressed in the empirical literature. However, a number of analyses on the match between workers education levels and those required by jobs have been published over the last 10 years. Obviously, the level of formal education completed by workers is more easily observed than their levels of human capital competences. Indeed, the latter would be rather difficult to observe. Nonetheless, this approximation is not straightforward, since formal education is only a mean for the acquisition of some human capital competences. We cross-examine the education match and the competence match between the supply and the demand of labor in Spain with data from 1998. Our results suggest that both types of matches do differ in their incidence, determinants, and wage consequences. 相似文献

This paper considers several possible channels behind the well‐documented effect of education on earnings. The first channel is that education makes workers more productive on a given task, as in a conventional human capital framework. The second channel is based on the idea that education helps workers get assigned to higher‐paying occupations where output is more sensitive to skill. A third and final channel is that workers are more productive and earn more when they are matched to a job related to their field of study. Using data from the 2005 National Graduate Survey and the 2006 Canadian Census, I find that channels two and three account for close to half of the conventionally measured return to education. The results indicate that the return to education varies greatly depending on occupation, field of study and the match between these two factors. 相似文献

We distinguish learning in a static environment from that in a dynamic environment to show the existence of an important interaction between the development of new technologies and human capital accumulation. Because technological progress creates a more dynamic environment, it complements education in the production of human capital by enhancing adaptive skills. Higher levels of adaptability and human capital in turn determine the profitability of new inventions and the incentive to invest in new R&D. Differences in the history of technological progress produce different levels of adaptability and our results suggest why countries that have comparable levels of education and per capita incomes may differ significantly in their growth performance. 相似文献

This paper calculates the quantitative significance of the welfare costs of union wage compression. This is done in a dynamic general equilibrium model with overlapping generations where agents choose both schooling (human capital) and assets (physical capital). The labor market in this model is characterized as a right-to-manage contract, which allows unions to compress wage differentials between high- and low-skilled workers, by implementing a binding minimum wage. This paper shows that when labor markets are competitive even low levels of wage compression lead to large welfare losses, since wage compression creates costly unemployment among low-skilled workers. The effect of wage compression on the supply of skilled labor, however, is rather small, since the disincentive effect of a lower, high-skilled wage is, to a large extent, offset by a lower opportunity cost of schooling due to higher unemployment. 相似文献

We study effects of mobility costs in a model of (Nash) wage bargaining between workers and firms, with instantaneous matching, heterogeneous workers, identical firms and free firm entry, and where firms can screen workers perfectly according to their previous work history but not their actual productivity. We derive the employment level and the minimum worker quality standard, in the market solution, and in the efficient solution established by a social planner. When workers have positive bargaining power, there is always some inefficient unemployment among desired workers in the market solution. The lowest hiring standard chosen by firms is higher than the planner's standard when firing costs are high relative to hiring costs, but may be lower in the opposite case. We show that any higher established hiring standard corresponds to a market equilibrium. The model explains a tendency for a high initial unemployment rate to remain high, particularly for low-skilled workers. 相似文献

We analyze the interaction between job tenure and external labor market conditions in wage determination. First, we introduce a model that combines job matching with business-cycle effects. As the employment relationship progresses, the worker appropriates a portion of the value of the match-specific human capital she accumulates, gradually becoming shielded from the cyclical variations in external labor market conditions: the employment relationship is progressively “internalized”. Then, we present empirical evidence supporting this prediction: the elasticity of wages to the unemployment rate decreases with tenure. This finding is robust to different specifications that allow for job heterogeneity, and it contributes to the interpretation of recent evidence of changes in the effect of the business cycle on wages. 相似文献

Abstract. The latest study investigating the cost–benefit ratio of apprenticeship training for Swiss companies has shown that most apprentices offset the cost of their training during their apprenticeship on the basis of the productive contribution of the work they perform. Given this outcome, it is worth investigating why so many firms choose not to train apprentices. Maximum-likelihood selection models were used to estimate the net cost of training for firms without an apprenticeship programme. The models show, firstly, that non-training firms would incur significantly higher net cost during the apprenticeship period if they would switch to a training policy and, secondly, that this less favourable cost–benefit ratio is determined less by cost than by absence of benefit. For the apprenticeship system as such the results indicate that, as long as training regulations and the market situation permit a cost-effective training of apprentices, companies do not need specific labour market regulations or institutions to offer training posts. In this respect, the Swiss findings might be of interest for the ongoing German discussion about the expected repercussions of a more general labour market deregulation on the apprenticeship training system. 相似文献

This paper builds on the recent literature on the importance of occupational and industry experience on wages and extends Kambourov and Manovskii's (2002) study using British data. Occupational experience is estimated to make a significant contribution to wage growth, while the evidence on industry specificity is not very supportive. The second contribution of the paper is that it assesses whether there is heterogeneity in the estimated returns to work experience across one-digit industries and occupations. The findings suggest that industry and occupational experience is important for individuals in professional and managerial jobs or jobs in the banking and finance sector. 相似文献

Abstract . Using the Canadian General Social Survey we compute returns to post-secondary education relative to high school. Unlike previous research using Canadian data, our data set allows us to control for ability selection into higher education. We find strong evidence of positive ability selection into all levels of post-secondary education for men and weaker positive selection for women. Since the ability selection is stronger for higher levels of education, particularly for university, the difference in returns between university and college or trades education decreases slightly after accounting for ability bias. However, a puzzling large gap persists, with university-educated men still earning over 20% more than men with college or trades education. 相似文献

This paper considers educational investment, wages and hours of market work in an imperfectly competitive labour market with heterogeneous workers and home production. It investigates the degree to which there might be both underemployment in the labour market and underinvestment in education. A central insight is that the ex post participation decision of workers endogeneously generates increasing marginal returns to education. Although equilibrium implies underinvestment in education, optimal policy is not to subsidise education. Instead it is to subsidise labour market participation which we argue might be efficiently targeted as state-provided childcare support. 相似文献

Abstract. We estimate the effects of the quality of the college a student attends on their later earnings using data from a cohort of US college students from the late 1970s and early 1980s. We rely on a linear selection on observables identification strategy, which is justified in our context by a very rich set of conditioning variables. We find economically important earnings effects of college quality for men and women, as well as effects on educational attainment, spousal earnings and other demographic variables. These effects remain roughly constant over time and result primarily from effects on wages, rather than from effects on hours or labor force participation. We find that, over the lower part of the range of college quality, increases in college quality (which entail higher expenditures per student) pass a simple social cost–benefit test. 相似文献

This study uses the Household, Income and Labour Dynamics in Australia (HILDA) survey to investigate the effect of health on wages of working-age Australian men. A simultaneous equation model of health and wages is estimated to account for the endogeneity of health. The results confirm the findings in the literature that health has a significant and positive effect on wages; it is also found that treating health as exogenous underestimates the effect substantially. Although the reverse effect of wages on health is found to be insignificant, there is evidence on the endogeneity of health arising from unobserved factors. 相似文献

We propose a new framework to analyse the relationship between the relative high-skilled labour endowment, the skill premium and economic growth. Building on Acemoglu and Zilibotti (2001), we introduce physical capital; internal costly investment in both capital and R&D; and complementarities between intermediate goods. We only find a positive relationship between the relative labour endowment and both the skill premium and economic growth within determined intervals of relative labour endowment values, which vary with the absolute productive advantage of high over low-skilled labour. The model thus accommodates theoretically mixed empirical results on the relative labour endowment-skill premium relationship. We further find that the impact on both the relative labour endowment and the skill premium of a rise in investment costs or in the complementarities degree depends on: (i) the absolute productivity advantage of high over low-skilled labour; and (ii) the relative labour endowment. 相似文献

Policy‐makers typically interpret positive relations between venture capital (VC) investments and innovations as evidence that VC investments stimulate innovation (VC‐first hypothesis). This interpretation is, however, one‐sided because there may be a reverse causality that innovations induce VC investments (innovation‐first hypothesis): an arrival of new technology increases demand for VC. We analyze this causality issue of VC and innovation in the US manufacturing industry using both total factor productivity growth and patent counts as measures of innovation. We find that, consistent with the innovation‐first hypothesis, total factor productivity growth is often positively and significantly related with future VC investment. We find little evidence that supports the VC‐first hypothesis. 相似文献

Earnings inequality and the business cycle 总被引:1,自引:0,他引:1
Economists have long viewed recessions as contributing to increasing inequality. However, this conclusion is largely based on data from a period in which inequality was increasing over time. This paper examines the connection between long-run trends and cyclical variation in earnings inequality. We develop a model in which cyclical and trend inequality are related, and find that in our model, recessions tend to amplify long-run trends, i.e. they involve more rapidly increasing inequality when long-run inequality is increasing, and more rapidly decreasing inequality when long-run inequality is decreasing. In support of this prediction, we present evidence that during the first half of the 20th century, when earnings inequality was generally declining, earnings disparities indeed appeared to fall more rapidly in downturns, at least among workers at the top of the earnings distribution. 相似文献

Many artists are prone to high unemployment and low incomes suggesting low job satisfaction. Our analysis including 49 countries paints a different picture. On average artists enjoy higher job satisfaction than other employees, mainly due to more autonomy. 相似文献
