What accounts for the differences in the kinds of communities within the metropolis in which members of different racial and ethnic groups live? Do socioeconomic advancement and acculturation provide greater integration with whites or access to more desirable locations for minority-group members? Are these effects the same for Asians or Hispanics as for blacks? Does suburbanization offer a step toward greater equality in the housing market, or do minorities find greater discrimination in the suburban housing market? Data from 1980 for five large metropolitan regions are used to estimate "locational-attainment models, " which evaluate the effects of group members’ individual attributes on two measures of the character of their living environment: the socioeconomic standing (median household income) and racial composition (proportion non-Hispanic white) of the census tract where they reside. Separate models predict these outcomes for whites, blacks, Hispanics, and Asians. Net of the effects of individuals’ background characteristics, whites live in census tracts with the highest average proportion of white residents and the highest median household income. They are followed by Asians and Hispanics, and-at substantially lower levels-blacks. Large overall differences exist between city and suburban locations; yet the gap between whites and others is consistently lower in the suburbs than in the cities of these five metropolitan regions.  相似文献

ABSTRACT: It is noticed that in both theoretical and empirical analyses concerning the relationship between corporatism and economic performance, the role of government is kept rather implicit. This article aims to incorporate government into the analysis in a more explicit way by analyzing whether government policies differ between corporatist and non-corporatist countries. The empirical results of the research reveal that corporatist countries are not only characterized by centralization or coordination of wage bargaining, but also by relatively high government expenditure, tax revenues, a higher ratio of active to passive labour market policies and also higher average unemployment benefits.  相似文献

We study adaptive importance sampling (AIS) as an online learning problem and argue for the importance of the trade-off between exploration and exploitation in this adaptation. Borrowing ideas from the online learning literature, we propose Daisee, a partition-based AIS algorithm. We further introduce a notion of regret for AIS and show that Daisee has 𝒪 ( T ( log T ) 3 4 ) cumulative pseudo-regret, where T $$ T $$ is the number of iterations. We then extend Daisee to adaptively learn a hierarchical partitioning of the sample space for more efficient sampling and confirm the performance of both algorithms empirically.  相似文献

In this paper, I study the production of academic research by economics departments and economists. Worldwide rankings are provided based on both citations and publications. These rankings reveal a dominant position of the United States in the production of economics literature. Over time, however, the extent of this dominance is decreasing. (JEL: A10, A14)  相似文献
