Prejudiced groups self-segregate and exclude others. This is observed in South African apartheid, in the exclusion of Eastern European or Muslim immigrants from Western Europe and in ghettos formed by immigrants in many countries. In the United States, minorities (mostly African Americans) are segregated in central cities and wealthier European Americans reside predominantly in the suburbs. A fully closed general equilibrium model of the last case is presented. The model treats land, labor and product markets. Most whites flee the inner city for white-dominated suburbs. This benefits blacks by lowering inner city rents relative to wages. When whites are weakly prejudiced, exclusion from the suburbs hurts whites as well as blacks. But when whites are strongly prejudiced, a lump sum endowment transfer from whites to blacks can split the gains-from-trade: whites can pay transfers to blacks in exchange for blacks accepting exclusion. The transfer needed to compensate blacks is large if blacks are strongly hurt by exclusion and small if they are only slightly hurt. How much transfers to US central cities and to the poor compensate American blacks for the effects of exclusion is an open question. 相似文献

In this paper, a general method of constructing control charts for preliminary analysis of individual observations is presented, which is based on recursive score residuals. A simulation study shows that certain implementations of these charts are highly effective in detecting assignable causes. 相似文献

This article examines the performance of index equity funds in Australia. Despite the significant growth in index funds since 1976, when the first index mutual fund was launched in the U.S., research on their performance is sparse in the U.S. and non-existent in Australia. This study documents the existence of significant tracking error for Australian index funds. For example, the magnitude of the difference between index fund returns and index returns averages between 7.4 and 22.3 basis points per month across index funds operating for more than five years. However, there is little evidence of bias in tracking error implying that these funds neither systematically outperform nor underperform their benchmark on a before cost basis. Further analysis provides evidence that the magnitude of tracking error is related to fund cash flows, market volatility, transaction costs and index replication strategies used by the manager. 相似文献

The implementation of structural adjustment programs (SAPs) has often been undermined by opposition from politically powerful groups who are favored by existing policies. To assess the political sustainability of SAPs this paper uses social accounting matrices for three African countries to model the income effects of stylized SAPs on different socioeconomic groups. The analysis reveals wide variation in the likelihood for typical SAPs to be acceptable to political elites while generating growth in the rest of the economy. The presence of a rural elite or strong farm-nonfarm linkages can enhance the political sustainability of SAPs. 相似文献

Summary. I show that aggregate-taking behavior is often evolutionarily stable for finite population in symmetric games in which payoff
depends only on own strategy and an aggregate. I provide economic examples exhibiting this phenomenon.

Behavioural Microsimulation with Labour Supply Responses 总被引:1,自引:0,他引:1
This paper provides a technical survey of recent developments in behavioural microsimulation. We discuss the criteria by which models of labour supply may be chosen for application to behavioural microsimulation, and consider how such models may be augmented to control for fixed costs, child–related work costs, preference heterogeneity and endogeneity in wages. We describe methods by which non–linear budget constraints may be accommodated in estimation, policy simulations and welfare analysis, and discuss how stochastic terms may be factored into the simulation of behavioural responses to a policy shock. 相似文献
