We construct a vintage capital model à la Whelan (2002) with both exogenous embodied and disembodied technical progress, and variable utilization of each vintage. The lifetime of capital goods is endogenous and it relies on the associated maintenance costs. We study the properties of the balanced growth paths. First, we show that the lifetime of capital is an increasing (resp. decreasing) function of the rate of disembodied (resp. embodied) technical progress. Second, we show that both the use-related depreciation rate and the scrapping rate increase when embodied technical progress accelerates. However, the latter drops when disembodied technical progress accelerates while the former remains unaffected. A key feature of our model is that the age-related depreciation rate does depend on the obsolescence rate in sharp contrast to the neoclassical model.

The objective of this paper is to analyze empirically the problem of mobbing in Spain. Based on the fifth Spanish survey on working conditions, we find that during 2003, around 5% of workers declared being mobbed at their workplace. Some personal, job characteristics and working conditions are found to be significant at explaining the probability of being a mobbing victim. Finally, we find differences in the variables affecting such probability depending on the victim's gende

In the traditional literature on the Lucas–Uzawa model, it is proved that in the so‐called normal parametric case, human capital stock grows at a rate greater than its long‐run counterpart in the neighbourhood of the long‐run balanced growth path. We first prove that the claim is true outside the neighborhood of balanced growth paths. More importantly, we identify a crucial asymmetry: whatever the parametric case considered, physical capital stock always grows at a rate lower than its long‐run counterpart when the ratio of physical to human capital is above its long‐run value.
