Our study provides the first national analysis of the labour market implications of workers who are licensed by any agency of the government in the USA. Using a specially designed Gallup survey of a nationally representative sample of Americans, we provide an analysis of the influence of this form of occupational regulation. We find that 29 per cent of the workforce is required to hold a licence, which is a higher percentage than that found in other studies that rely on state‐level occupational licensing data or single states. Workers who have higher levels of education are more likely to work in jobs that require a licence. Union workers and government employees are more likely to have a licence requirement than are non‐union or private sector employees. Our multivariate estimates suggest that licensing has about the same quantitative impact on wages as do unions — that is about 15 per cent — and that being both licensed and in a union can increase wages by more than 24 per cent. However, unlike unions which reduce variance in wages, licensing does not significantly reduce wage dispersion for individuals in licensed jobs. 相似文献

Prior to the end of 1989, most sectors of the UK retail trade had for some time been benefiting from a boom in sales. Many reasons may be forwarded to explain the high level of sales that had devéloped. This paper focuses attention on the greatly increased levels of consumer credit indebtedness associated with high retail sales. Examination is made of the possibility that a fundamental change in UK patterns of saving and spending has taken place. It is suggested that the retail trade must pay attention to the implications of rising credit and of any restrictions on consumer credit that may be introduced at some future date. 相似文献

This paper presents a model of investment in which heterogeneous firms choose between new investment and acquisitions. New investment involves purchasing a new plant for an existing variety. Acquisitions involve purchasing a plant and a variety from a selling firm. Using a variable‐elasticity demand system, I show that if varieties within a differentiated industry are imperfect substitutes, mid‐productivity firms invest. As varieties approach perfect substitutability, high‐productivity firms invest. For both cases, within the region of investing firms, the most productive choose acquisitions over new investment. In analyzing firm‐level data from Compustat, I find evidence that supports these predictions. 相似文献

Equity is a major public concern related to recreation fees on public lands. The purpose of this study was to test a three-dimensional model of equity and to examine the perceptions of equity across demographic segments. Data were collected by a telephone survey with residents (N = 366) of two western states. Confirmatory factor analysis supported the three-dimensional equity model in a recreation fee context. People tended to support democratic equity more than compensatory equity. Greater support was shown for discounted fees for the elderly and persons with disabilities than for discounts for ethnic minorities, low income people, or large families, suggesting the possibility of two sub-dimensions of the compensatory equity construct. Overall, the results do not support that disadvantaged groups seek discounted fees. 相似文献

'Individualization' in personnel practices has long been considered as an essential component of 'modern' human resources management, but the empirical complexities of its definition, implementation and impact within firms have not been analysed in considerable depth. This paper adds to this analysis by reporting on research into one form of individualization - 'skill-based pay' - adopted in different sectors in France. The crucial institutional context for this adoption is explained and then it is shown how different models of skill-based remuneration have emerged as a result of both sectorial contingencies and specific industrial relations processes. 相似文献

Least squares model averaging by Mallows criterion 总被引:1,自引:0,他引:1
This paper is in response to a recent paper by Hansen (2007) who proposed an optimal model average estimator with weights selected by minimizing a Mallows criterion. The main contribution of Hansen’s paper is a demonstration that the Mallows criterion is asymptotically equivalent to the squared error, so the model average estimator that minimizes the Mallows criterion also minimizes the squared error in large samples. We are concerned with two assumptions that accompany Hansen’s approach. The first is the assumption that the approximating models are strictly nested in a way that depends on the ordering of regressors. Often there is no clear basis for the ordering and the approach does not permit non-nested models which are more realistic from a practical viewpoint. Second, for the optimality result to hold the model weights are required to lie within a special discrete set. In fact, Hansen noted both difficulties and called for extensions of the proof techniques. We provide an alternative proof which shows that the result on the optimality of the Mallows criterion in fact holds for continuous model weights and under a non-nested set-up that allows any linear combination of regressors in the approximating models that make up the model average estimator. These results provide a stronger theoretical basis for the use of the Mallows criterion in model averaging by strengthening existing findings. 相似文献

The paper reviews the contemporary literature on the experience of teleworking. Particular attention is paid to the socializing aspects of work and its comparative absence when working from home; economic considerations, both for homeworkers and for the firms; work satisfaction and motivation; supervision; roles and gender issues in homeworking; the organization of time and space; and, lastly, questions of self-discipline. The evidence reviewed is based on various teleworking trials conducted mainly during the 1980s; this information is supplemented by original research conducted by the authors which investigated the pros and cons raised by British Telecom operators who were due to take part in a teleworking trial. These operators anticipated many of the issues faced by those who actually had teleworking experience. 相似文献
