Using nonparametric, production‐frontier methods, we decompose labor productivity growth into components attributable to technological change (shifts in the world production frontier), technological catch‐up (movements toward or away from the frontier), and physical and human capital accumulation (movements along the frontier). We find that (1) technological change is decidedly nonneutral, (2) productivity growth is driven primarily by physical and human capital accumulation, (3) the increased international dispersion of productivity is explained primarily by physical capital accumulation, and (4) international polarization (the shift from a unimodal to a bimodal distribution) is brought about primarily by efficiency changes (technological catch‐up).  相似文献

This article shows that reverse discrimination policies can find a justification purely on efficiency grounds. We study the optimal provision of education when households belong to different groups, differing in the distribution of the potential to benefit from education among individuals, which is private information. The main result is that high‐potential individuals from groups with relatively few high‐potential individuals should receive more education than otherwise identical individuals from groups with a more favorable distribution of these benefits.  相似文献

We consolidate and generalize some results on price determination and efficiency in search equilibrium. Extending models by Rubinstein and Wolinsky and by Gale, heterogeneous buyers and sellers meet according to a general matching technology and prices are determined by a general bargaining condition. When the discount rate r and search costs converge to 0, we show that prices in all exchanges are the same and equal the competitive, market clearing, price. Given positive search costs, efficiency obtains iff bargaining satisfies Hosios' condition and r=0. When prices are set by third‐party market makers, however, we show that search equilibrium is necessarily efficient.  相似文献

This paper considers the issues of existence and uniqueness of average cost pricing equilibria within the context of a single, regulated, multiproduct monopoly with additively separable costs. We employ basic degree theoretic arguments to establish conditions under which an average cost pricing equilibrium exists. The degree theoretic approach permits the development of uniqueness results in a very natural manner.  相似文献

Numerous studies document that criminal activity is positively related to unemployment and negatively related to educational attainment levels within given communities. We study this phenomenon in the context of a search‐equilibrium model, in which agents choose between formal employment and pursuing crime‐related activities (theft). Prior to their “occupational choices,” agents undertake costly schooling, raising their productivity. Crime acts, in essence, as a tax on human capital by affecting the probability that a worker's earnings (possessions) are subsequently appropriated. There are multiple equilibria. High crime, low levels of educational attainment, long spells of unemployment, and poverty are correlated across them.  相似文献

This paper seeks to re‐examine the issue of estimating team efficiency for sports teams via an application of data from the National Basketball Association. This paper argues that the inputs the coaches allocate are the players the team employs. Therefore, this paper employs a measure of playing talent in modeling team production. Unlike previous studies, which only employed one measure of playing talent, we employ measures of guards, small forwards and big men in a study of basketball. This paper also argues that the time‐varying stochastic frontier models with the identical temporal pattern assumption such as Lee and Schmidt and Battese and Coelli cannot be used in the analysis of team efficiency in sports. The evidence we present shows by hypothesis test that this argument holds.  相似文献

Students’ success during their first year at university is largely influenced by their university entrance score. Personal characteristics and secondary school characteristics also impact on success. This paper uses quantile regression to investigate how the effects of these factors vary along the grade distribution. It finds that the factors which influence grades have a more pronounced impact on the success of low‐achieving students than on that of high‐achieving students. These results have implications for student selection and also for the way scholarships may be used to attract talented high school students.  相似文献

We build up a Ricardian trade model with multiple regions within a nation and examine how international trade determines interregional patterns of production and specialization. We show that the degree of interregional concentration of economic activities moves in different directions in two trading nations. The role of “absolute advantage” becomes crucial in dictating the course of income disparity across regions. We discuss cases with varying degrees of labour mobility and reconfirm the result on post‐trade interregional concentration and dispersion. Later we explore the impact of “scale factor” in this model and show how principle of comparative advantage and economies of scale interact to determine the pattern of specialization and volume of trade.  相似文献

This paper analyses the effect of raising effective marginal tax rates on the income of the representative household in each gross income decile in Australia by one percentage point, and distributing the proceeds of the tax increase either in the form of an equal per capita grant, or as an equal payment to members of households in the lower half of the income distribution. The effectiveness of the program in redistributing income is measured as the ratio of total gains in disposable income to households in target deciles to losses in non-target groups, or as the proportional reduction in the poverty gap. The cost is measured as the ratio of the sum of the income-equivalent of changes in the welfare of non-target groups to those of target groups, or as the ratio of income-equivalent losses to gains.  相似文献

Following the New Zealand Electricity Industry Reform Act in 1998 integrated electricity distribution and retail companies were forced to unbundle at ownership level, creating line companies and retailers. Electricity line companies that meet the ‘consumer‐owned’ criteria as set out in the Commerce Act are exempt from price‐quality regulation as of 2009. In this study, we examine the effects on variable costs and unit prices of the exemption by comparing exempt line companies and line companies that fall under the price‐quality regulation. The findings suggest that exempt line companies did not charge higher prices than non‐exempt line companies, and that they experienced a larger decline in their variable costs compared to non‐exempt line companies, following the exemption.  相似文献

Unemployment insurance (UI) distorts firms' layoff decisions by reducing the cost of laying off workers. To dampen this increase, it has been suggested that UI should be financed with an experience‐rated tax. Despite the fact that increasing the level of experience rating can reduce unemployment, it can reduce the insurance coverage workers receive. With high experience rating, firms may reduce their severance payments by more than the UI benefit. We build a model where competitive firms offer contracts with severance payments to risk‐averse workers. Frictions in the labor market lead to incomplete insurance. This article shows that less than full‐experience rating enables the government to increase the insurance coverage workers receive. Welfare implications are also investigated.  相似文献

We construct a two-period model of industry-specific quid pro quo direct foreign investment (DFI) which occurs with the view to increasing the level of a future voluntary export restraint (VER). The wage and the VER are determined through Nash bargaining. We identify the conditions which generate quid pro quo DFI and examine its effects on profits, the utility of the union and welfare. In the absence of political-economy considerations, more DFI increases the degree of endogenous protection.  相似文献
