Learning from experience or learning from others?: Inferring informal training from a human capital earnings function with matched employer–employee data

A model of informal training which combines learning from own experience and learning from others is proposed in this paper. It yields a closed-form solution that revises Mincer–Jovanovic's [Mincer, J., Jovanovic, B., 1981. Labor mobility and wages. In: Rosen, S. (Ed.), Studies in Labor Markets. Chicago University Press, Chicago, pp. 21–64] treatment of tenure in the human capital earnings function. We estimate the structural parameters of this non-linear model on a large French cross-section with matched employer–employee data. We find that workers on average can learn from others 10% of their own human capital on entering one plant, and catch half of their learning from others’ potential in just 2 years. The private marginal returns to education are declining with education as more educated workers have less to learn from others and share the social returns of their own education with their less qualified co-workers. The potential for learning from others on the job varies across jobs and establishments, and this provides a new distinction between imitation jobs and experience jobs. Workers in imitation jobs, who learn most from others, tend to have considerably longer tenure than workers in experience jobs. Although workers in experience jobs can learn little from others, we find that they learn a lot by themselves. We document several analogies between the imitation jobs/experience jobs “dualism” and the primary/secondary jobs and firms’ dualism implied by the dual labor market theory. However, our binary classification of jobs depicts the data more closely than the dual theory categorization into primary-type and secondary-type establishments. Competition prevails between jobs and firms but jobs differ by their learning technology.     

评深化对劳动价值理论研究的两种思路

本文就当前深化对劳动价值理论研究的“要素价值论”和“活劳动价值论”这两种思路作出了较系统的评述。对“要素价值论”主张的物化劳动创造价值、科学技术创造价值和各种非劳动要素共同创造价值的观点作了深入的分析,指出了这些观点在理论上存在的问题,因而按这一思路来进行研究不能达到深化对劳动价值理论认识的目的。对“活劳动价值论”主张的应深化认识创造价值的劳动这一观点作了深入的分析,在肯定这一研究思路所取得的重要成果的基础上,指出了需要进一步深入研究的几个主要问题,以及深化对劳动价值理论研究的主攻方向。

Ageing, health and productivity: A challenge for the new millennium

The economic implications of Europe's ageing population are considerable. Without an increase in the size of the working population, reducing the possible fiscal deficits will be difficult. This paper reviews this area of increasing concern for basic, applied and strategic researchers, namely how to increase the age at which people typically stop working, without damaging health or productivity. Chronological age per se may not be a good predictor of health and job performance; rather we should examine various mediating and moderating factors. It is argued that attention should focus on national and organizational policies, management attitudes, training, work demands, the working environment, work organization, the psychosocial environment and health promotion. Older workers may currently be subject to discriminatory practices and to stereotypical and inappropriate attitudes which may adversely affect their health and performance. Flexible and intelligent solutions are required. Many organizations, perhaps reflecting western culture, have not yet evolved to the point where the potential contribution of older people is recognized and allowed to flourish. Once current barriers are removed, and existing and developing knowledge applied, an optimistic picture for older workers emerges.     

穆勒女性主义思想评析

Did wages reflect growth in productivity?

The level of productivity doubled in the U.S. nonfarm business sector between 1970 and 2006. Wages, or more accurately total compensation per hour, increased at approximately the same annual rate during that period if nominal compensation is adjusted for inflation in the same way as the nominal output measure that is used to calculate productivity. Total employee compensation as a share of national income was 66% of national income in 1970 and 64% in 2006. This measure of the labor compensation share has been remarkably stable since the 1970s. It rose from an average of 62% in the decade of the 1960s to 66% in the decades of the 1970s and 1980s and then declined to 65% in the decade of the 1990s where it has again been from 2000 until the most recent quarter.     

Exchange rate and wage policies in Central and Eastern Europe

After the eastern enlargement of the European Union (EU) and due to increasing labor market integration, wage determination in Central and Eastern Europe (CEE) has become a key issue in European economic policy making. In addition, a controversial discussion concerning the monetary integration of CEE countries into the EMU has emerged. Both issues have earned particular academic and political interest because Eastern and Western Europe are at different stages of economic development and volatile international capital flows seem to require either a higher degree of wage or exchange rate flexibility. Based on the Scandinavian model of wage adjustment by Lindbeck (1979), we analyze the role of exchange rates in the wage determination process of the Central and Eastern European countries to identify which exchange rate strategy contributes to faster wage convergence in Europe. Panel estimations suggest that workers in countries with fixed exchange rates are likely to benefit in the long run from higher wage increases.     

Maux du travail : dégradation, recomposition ou illusion ?

In recent years, the attention of French public opinion has been focused on the noxious effects of new ways of organizing work. Stress, “suffering”, burnout, psychosocial risks and suicides are topics that have brought experts, the media and politicians into action. What do the social sciences have to say about this? Among the several reactions presented, the principal contrast arises between those who analyze the ills of work as “social constructions” and those who see them as the implications of a trend toward intensifying job-related activities.     

Growth impact of climate change and response policies: The advanced climate change long-term (ACCL) model

This paper provides a tool to build climate change scenarios to forecast Gross Domestic Product (GDP), modelling both GDP damage due to climate change and the GDP impact of mitigating measures. It adopts a supply-side, long-term view, with 2060 and 2100 horizons. It is a global projection tool (30 countries/regions), with assumptions and results both at the world and the country/regional level. Five different types of energy inputs are taken into account according to their CO₂ emission factors. Full calibration is possible at each stage, with estimated or literature-based default parameters. Compared to other models, it provides a comprehensive modelisation of Total Factor Productivity (TFP), which is the most significant determinant of the GDP projected path. We present simulation results of different energy policy scenarios. They illustrate both the “tragedy of the horizon” and the “tragedy of the commons”, which call for a policy framework that adequately integrates a long run perspective, through a low-enough discount rate and an effective intergenerational solidarity as well as international cooperation.
