This paper uses a sub-sample ( N = 5,800) of a unique data set on work and lifelong learning to develop the learning dimension of the Job Demand-Control model ( Administrative Science Quarterly [1979] 24:285 ). The model is expanded by including three distinct learning behaviors to allow for a complete assessment of workplace learning. Worker control is also expanded to include often confounded dimensions of Social and Technical Control. The results confirm that different types of learning are related to different determinants and that Social and Technical Control are key factors in learning participation. 相似文献

Lucas (1987, 2003) estimates that the cost of economic fluctuations is low; a social planner would pay no more than 0.1% of (permanent) consumption to eliminate all future business cycle fluctuations. The current paper extends Lucas’ calculations by studying the costs of fluctuations arising from asset bubbles. We estimate two classes of costs: consumption volatility due to asset bubbles in a representative agent economy and consumption volatility that arises because households have heterogeneous exposure to the bubble assets. We show that the magnitude of welfare costs is primarily driven by the existence of heterogeneity. Our benchmark calibration implies that the asset bubbles of the last decade generated a social welfare cost equal to a permanent 3% reduction in the level of national consumption. If assets are held proportionately across the population, these welfare costs fall by an order of magnitude. Our calculations are sensitive to the details of the calibration, including the degree of balance sheet and trading heterogeneity, the coefficient of relative risk aversion, and the magnitude of the asset bubble. Our preferred specifications generate welfare costs ranging from 1% to 10% of (permanent) national consumption. 相似文献

This article analyses the determinants of voluntary contribution to environmental quality by introducing the perception of environmental risk. We consider individuals who are aware both of the impact of their voluntary contributions and of the quality of the current environment on the future quality of environment. Their preferences are represented by the RDU model. We distinguish three kinds of effect: environmental quality, wealth and risk perception. The first effects are not always sufficient to explain agents' implication in the improvement of environmental quality. 相似文献
