Interest in the efficiency or inefficiency of non-profit firms has spawned research on the administrative costs of Blue Cross and Blue Shield plans. Relying on plausible implications of the property rights theory of the firm, both Blair, Ginsburg, and Vogel (1975) and Vogel (1977) noted some evidence of inefficiency in these firms. Our analysis, however, utilizing their models and more recent data, reveals little convincing evidence for the view that Blue Shield plans are inefficient.  相似文献

A discussion of the 1980 U.S. census is presented. The authors suggest that the taking of a national census is not just a statistical exercise, but an exercise involving ethics, epistemology, law, and politics. They contend that conducting a national census can be defined as an ill-structured problem in which the various complexities imposed by multidisciplinarity cannot be separated. "The 1980 census is discussed as an ill-structured problem, and a method for treating such problems is presented, within which statistical information is only one component."  相似文献

The relationship between the ethnic characteristics of immigrants to the United States and their occupational mobility in the short term is explored. The data concern the period 1965-1970 and are taken from the 1970 census. The results indicate that race and sociocultural distance have important effects on occupational mobility. The study also shows that if educational status is controlled, the performance of Asian immigrants is more similar to that of blacks or Hispanics than it is to that of whites.

How do marital status,work effort,and wage rates interact?   总被引:1,自引:0,他引:1  
Ahituv A  Lerman RI 《Demography》2007,44(3):623-647
How marital status interacts with men's earnings is an important analytic and policy issue, especially in the context of debates in the United States over programs that encourage healthy marriage. This paper generates new findings about the earnings-marriage relationship by estimating the linkages among flows into and out of marriage, work effort, and wage rates. The estimates are based on National Longitudinal Survey of Youth panel data, covering 23 years of marital and labor market outcomes, and control for unobserved heterogeneity. We estimate marriage effects on hours worked (our proxy for work effort) and on wage rates for all men and for black and low-skilled men separately. The estimates reveal that entering marriage raises hours worked quickly and substantially but that marriage's effect on wage rates takes place more slowly while men continue in marriage. Together; the stimulus to hours worked and wage rates generates an 18%-19% increase in earnings, with about one-third to one-half of the marriage earnings premium attributable to higher work effort. At the same time, higher wage rates and hours worked encourage men to marry and to stay married. Thus, being married and having high earnings reinforce each other over time.  相似文献

Ivanenko  V.I.  Munier  B. 《Theory and Decision》2000,49(2):127-150
It is shown that the uncertainty connected with a `random in a broad sense' (not necessarily stochastic) event always has some `statistical regularity' (SR) in the form of a family of finite-additive probability distributions. The specific principle of guaranteed result in decision making is introduced. It is shown that observing this principle of guaranteed result leads to determine the one optimality criterion corresponding to a decision system with a given `statistical regularity'.  相似文献

Technocratic social work conceived as the neutral application of professional skills has an inbuilt capacity for failing to recognize its social and political effects. Two recent books on social work exemplify this in countries as apparently diverse as Australia and Iran.  相似文献
