本文使用一个世代交叠模型揭示了公共教育与社会保障调节收入分布的作用机制。研究发现,公共教育能够有效地缩小家庭教育投资差距,从而降低收入差异;社会保障则通过减少低收入家庭的劳动供给、增加其有效家庭教育时间来降低收入差异。本文的数值模拟结果显示,在同样的支出水平下公共教育调节收入差异的能力比社会保障更强。并且当存在财政预算约束时,从降低收入差异的角度来看,若财政预算规模较低则应当将资金优先用于公共教育;若财政预算规模较高则应当在公共教育与社会保障之间保持平衡。 相似文献

We investigate trade and financial openness in a small developing country where entrepreneurs need bank financing to operate in an import‐competing sector but banks do not observe their ability. This informational asymmetry causes adverse selection of low‐ability individuals into entrepreneurship and also prevents poor but able individuals from being entrepreneurs. We find that trade opening improves national welfare, but a tax is needed on foreign financial capital. Trade opening reduces an income gap between the rich and the poor, while financial opening affects this income gap ambiguously. 相似文献

Abstract The focus of this survey is to discuss different attempts at incorporating the distributional dimension of human capital into the theoretical and empirical growth framework. We present a series of models which deviate from the direct link between the aggregate or average level of human capital and economic growth in that they introduce the distribution of education as a new element in explaining the relationship under investigation. After surveying the theoretical literature, we present recent empirical work on the relation between economic performance and the average level, as well as the distribution of education, respectively. 相似文献

This article presents an overview of several constructive methods for generating random probability measures. Applications of random probability measures include Bayesian statistics, average optimal control problems, average error bounds for numerical equation solving methods, and models for random distributions of mass in space. 相似文献

This article discusses trends in the distribution of retail development in Tirana (the capital of Albania) and its surrounding areas. The story of these trends in Tirana exhibits unique characteristics connected to the city's exceptional population growth and exceptional densification since the end of the communist era in 1990. Tirana provides an example of how a center city can continue to dominate retail commerce when there are very limited restraints on residential and commercial density in the inner city and very limited foreign investment in retail development. 相似文献

Online distribution of airline tickets: Should airlines adopt a single or a multi-channel approach? 总被引:1,自引:0,他引:1
In today's digital world, airlines typically distribute tickets both via their own websites and through online travel agency (OTA) platforms such as Expedia and Travelocity. Although associated with higher distribution costs, selling tickets through the platforms offers airlines exposure to a broader consumer base, and potentially higher sales than selling tickets solely through their own websites. While most airlines have adopted a multi-channel approach by selling tickets through OTA platforms and their websites, some (e.g., Southwest Airlines, easyJet and Ryanair) sell only via the latter. Is one approach better than the other, and if so, under what circumstances? This study analyzes factors that affect an airline's distribution strategy by developing a decision support model. We find that airlines are less likely to use OTA platforms if they have a large loyal consumer base or if the OTA platform is highly competitive. 相似文献

A computable general equilibrium (CGE) model of Dutch disease economics in Taiwan's economy is established in order to examine the impacts of the imbalanced growth in output, endogenous learning effects from imports and exports and the import tariff reduction. Twenty-nine industry sectors and five quintiles of households are taken to measure the changes in industry structure and functional distribution of income. An imbalanced growth, either from output or exports, contributes to the reduction in the share of manufacturing industry, but the deterioration in the functional distribution of income only happens to an imbalanced growth in intersectoral output. A widespread trade liberalization policy helps to mitigate the Dutch disease phenomenon in the sense that de-industrialization and deterioration of the distribution of income by an imbalanced growth in manufacturing industry are not so severe. 相似文献

Recursive formulae are derived for the evaluation of the moments and the descending factorial moments about a point n of mixed Poisson and compound mixed Poisson distributions, in the case where the derivative of the logarithm of the mixing density can be written as a ratio of polynomials. As byproduct, we also obtain recursive formulae for the evaluation of the moments about the origin, central moments, descending and ascending factorial moments of these distributions. Examples are also presented for a number of mixing densities. 相似文献

基于收入分布的收入差距扩大成因的分解 总被引:1,自引:0,他引:1
本文采用核平滑化的半参方法估计了1987年、1996年、2004年我国城市居民收入分布曲线,并且基于收入分布又进一步分解了导致城市居民收入差距扩大的主要原因。收入差距扩大的成因可以分为两类:一是劳动者的劳动力特点的普遍变化,如劳动者教育水平的提高,行业、职业分布的变化;二是对劳动力特点回报率的变化,如教育回报率的提高,各行业、职业回报率差异的扩大等。本文发现后者是导致收入差距扩大的主要原因。 相似文献
