This paper explores the efficiency of the equilibrium allocation in a matching model with heterogeneous workers and jobs. In the basic setup there are two types of workers with different skill levels. Both types can perform the simple tasks of unskilled jobs, while the complex tasks of skilled jobs require a high-ability worker. We demonstrate that the equilibrium outcome with random search and ex-post bargaining is never efficient. Under the Hosios condition, the average wage is correct, but bargaining compresses the wage distribution relative to workers’ shadow values. This feature distorts the relative profits of jobs, making it too attractive for firms to create skilled jobs. Furthermore, due to the low-skill premium, the high-ability workers may accept too many jobs. Finally, in an extension, we show that the introduction of separate markets for the two types of jobs is not sufficient to guarantee efficiency. 相似文献

This paper presents an empirical model of union wage setting and employment. The (Stackelberg) equilibrium unemployment rate is shown to be a function of taxes, the replacement ratio, the gap between consumer and producer prices, productivity effects, and the rate of long-term unemployment. The model is estimated with aggregate data from the private sector in the Netherlands (1965–1987). The results suggest that the equilibrium unemployment rate is pushed upwards by taxes, the replacement ratio and by the gap between consumer and producer prices, and is reduced by productivity effects. Insider-outsider effects appear insignificant. 相似文献

This paper aims to measure the contribution of an aging population to explain the real appreciation experienced by the Yen–US Dollar since 1980s. We develop a two-good overlapping-generation model of a semi-small open economy to highlight the link between the birth rate and the real exchange rate. In a creditor (debtor) country, an aging population causes a real exchange rate appreciation (depreciation) due to a positive (negative) wealth effect. Structural parameters are estimated by GMM using quarterly data between 1960 and 2001. Then, numerical simulations show that the long-run relationship between population growth and real exchange rate is negative between 1960 and 1971 and positive between 1971 and 2000. The decrease in population growth may account for a large part of the real appreciation experienced by the Yen/USD between 1971 and 2000. 相似文献

We consider a labor market with search frictions in which firms need to invest in capital before they can post a vacancy. This assumption creates a natural scope for hold-up problems, but the innovation of our study is that we allow for competition among the applicants who apply for the same job. In our economy all applicants are paid their actual marginal product. Nonetheless, with random search there exists a hold-up problem, leading to underinvestment in capital. On the contrary, if workers can direct their search towards firms with different capital levels, the equilibrium is efficient. This result contrasts sharply with the predictions of models with ex-post bargaining that never yield an efficient allocation. Moreover, our results extend the efficiency of auction mechanisms to an environment with non-contractible investments. 相似文献

This study examines the impact of regional competitiveness on the innovative activity of entrepreneurial firms. Based on a unique and hand-collected dataset of publicly listed high-technology start-ups and university regions, this paper tests how regional competitiveness and university spillovers affect the innovation behavior of entrepreneurial firms. The results provide strong evidence that regional competitiveness and university spillovers are strong complements in fostering innovation activity of entrepreneurial firms. However, the results also raise the question whether incentives for universities and their actors might lead to crowding out effects. 相似文献

Using a rich dataset from West Africa, we examine the household characteristics associated with membership in community-based organizations (CBOs). We find that on average it is the more fortunate members of rural society who belong in CBOs. In Senegal, the dominant criterion is land ownership. In Burkina Faso it is age and family ties with village authorities. Ethnicity plays a role as well: CBO membership is less likely for ethnic groups that traditionally emphasize livestock raising. Next we look for evidence of assortative matching along multiple dimensions, using an original methodology based on dyadic regressions. We find robust evidence of positive assorting by physical and ethnic proximity as well as by wealth and household size. Along certain dimensions, donor-sponsored CBOs are less elitist and more inclusive. But the reverse is true for other dimensions, particularly in Burkina Faso. 相似文献

We consider a class of household production models characterized by a dichotomy property. In these models the amount of time spent on household production does not depend on the household utility function, conditional on household members having a paid job. We analyse the (non‐parametric) identifiability of the production function and the so‐called jointness function (a function describing which part of household production time is counted as pure leisure). It is shown that the models are identified in the two‐adult case, but not in the single‐adult case. We present an empirical application to Swedish time‐allocation data. The estimates satisfy regularity conditions that were violated in previous studies and pass various specification tests. For this data set we find that male and female home production time are q‐substitutes. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

An interesting aspect of games is the relative extent to which a player can positively influence his results by making appropriate strategic choices. This question is closely related to the issue of how to distinguish between games of skill and games of chance. The distinction between these two types of games is definitely interesting from a juridical point of view. In this paper we present a modification of an existing measure of the skill level of a game, which has served as a juridical tool for the classification of games. The main difference is that this new definition does not automatically classify incomplete information games without chance moves as games of skill. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

Direct and inverse power Box–Cox transformations are used to characterize the form of heteroscedasticity in models where the variables themselves are subjected to direct Box–Cox transformations. Resulting formulations are extended to take serial correlation simultaneousy into account. 相似文献
