经济增长通常意味着贫困率的下降,然而,对于增长很慢的经济体或经济增长没有带动贫困率降低的案例,这种假设似乎并不成立.中国两个较为贫困省份的数据展示了这样一个谜题:贵州省的经济增长缓慢但农村贫困率的下降较为显著,对这一现象不妨称之为"贵州新现象";与此同时,云南省经济高速增长但贫困率下降较为迟缓.根据相关考察和统计数据的分析,交通、流动人口、旅游业和矿产业四个因素是解释这个谜题的关键.这四个因素在两个省的不同分布和构造解释了它们经济增长与贫困率下降关系中的不平衡性. 相似文献

Does the competition mode influence the delegation decisions of the firm owners? By constructing a vertical negotiation game model, we find that under Cournot competition in the downstream market, the downstream firm's owner will not choose delegation, whereas under Bertrand competition, the downstream firm's owner will choose delegation. If the product substitution is relatively large, the adoption of delegation management by the owners of downstream firms under Bertrand competition will bring higher profits. It further shows that compared with the situation of no delegation, delegation management may reverse the social welfare ranking under Bertrand and Cournot competitions. 相似文献

We propose to introduce some economic performance variables of the firms and relate these with the corresponding frontier efficiency measures of 13 industries of the Belgian manufacturing sector in 1978. In order to find groups of similar firms by applying a cluster technique, we assume that this relationship is of a product life cycle nature.In the light of the product life cycle scheme itself and variations of it we can consider the possible explanatory variables of technical inefficiency in each group of firms as sources which intensify or slow-down the economic performance of the firm under consideration. Some cautious characterization of the top and bottom level clusters is formulated and linked to the efficiency issue.This paper was processed by N. R. Adam 相似文献

Recent application of the switching regression model to allocate workers into the primary and secondary labor markets is
considered to be the best solution to the classification problem of the empirical testing of the dual labor market theory.
In such models, normality of the error terms is assumed. This paper adopts the switching regression model to test the dual
labor market theory by assuming different distributions of the error terms. The test results strongly support the dual labor
market theory regardless of the assumption one makes about the error terms. However, the results indicate that different distribution
can lead to different percentage distributions of workers in the two segments. In particular, the normal distribution generates
more workers in the primary segment than the non-normal distributions. Therefore, care must be taken not to generalize the
type of industries or occupations that fall under the primary and secondary segments.

Summary. We analyze an oligopoly model of homogeneous product price competition that allows for discontinuities in demand and/or costs.
Conditions under which only zero profit equilibrium outcomes obtain in such settings are provided. We then illustrate through
a series of examples that the conditions provided are “tight” in the sense that their relaxation leads to positive profit
outcomes.

The notion of a mixed-strategy Nash equilibrium suffers from three inherent difficulties. First, given the equilibrium strategies of other players, there are many best replies. Second, the equilibrium is unstable. Third, comparative statics results are counterintuitive. We demonstrate that these difficulties all have their origin in von Neumann and Morgenstern′s expected utility. In contrast, players with "quadratic utility" have unique best replies and the Nash equilibrium appears to yield intuitive comparative statics results.

Protecting human health is a primary goal of environmental policy and economic evaluation of health can help policy-makers judge the relative worth of alternative actions. Economists use two distinct approaches in normatively evaluating health. Whereas environmental economists use benefit-cost analysis supported by monetary valuation in terms of willingness-to-pay, health economists evaluate interventions based on cost-effectiveness or cost-utility analysis (CEA), using quality-adjusted life-years (QALY) or similar indexes. This paper provides background on the controversy about the relative merits of these approaches and introduces the remaining papers in the special issue. These papers (with one exception) were presented at a conference sponsored by the Department of Economics at the University of Central Florida with support from the US Environmental Protection Agency. Although CEA might not lead to substantially different implications for environmental policy than benefit-cost analysis, and QALY may provide a benefit transfer tool to fill gaps in the morbidity valuation literature, the papers in this issue raise serious concerns about the suitability of QALY-based CEA for environmental regulatory analysis. QALY does not in general appropriately represent individual preferences for health and CEA is neither independent of income distribution nor adequate to assess efficiency. 相似文献

We propose enforcement strategies for emissions trading programs with bankable emissions permits that guarantee complete compliance with minimal enforcement costs. Our strategies emphasize imperfect monitoring supported by a high unit penalty for reporting violations, and tying this penalty directly to equilibrium permit prices. This approach is quite different from several existing enforcement strategies that emphasize high unit penalties for emissions in excess of permit holdings. Our analysis suggests that a high penalty for excess emissions cannot be used to conserve monitoring effort, and that it may actually increase the amount of monitoring necessary to maintain compliance.The authors are grateful to Anthony Heyes and three anonymous referees for their valuable comments.
