Blue Shield plans often are granted regulatory advantages by the states in which they operate. Run efficiently, such not-for-profit firms should use these lower costs to eliminate their less advantaged rivals, the commercial insurers. However, these higher-cost commercial providers have been able to offer insurance coverage at prices competitive with the Blues, as evidenced by the fact that Blue plans have, on average, less than 50 percent market share. Similar prices with lower overall costs implies that economic rents are being earned, rents which a not-for-profit firm cannot distribute to owners. In this paper we argue that when there are competing goals among the groups controlling the Blue Shield plans, the different possible "uses" of the regulatory advantage become endogenously determined, necessitating the use of simultaneous equation estimation. Testing this model we find the major effect of doctor-control of Blue Shield plans is to raise doctors' fees while lowering the amount of rents captured by both consumers and administrators.  相似文献

What strengths and talents make an outstanding child care worker? How can these qualities be measured? How can one predict whether an individual will succeed as a child care worker? The authors attempt to answer these questions by focusing on the "life themes" of highly rated child care workers and using a technique to measure these themes.  相似文献

This study compared gay men in monogamous ("closed") relationships (n = 98) and gay men in nonmonogamous ("open") relationships (n = 34). Partners in open relationships were living together significantly longer than partners in closed relationships. Partners in the two types of relationships did not differ in Psychological Adjustment. Controlling for length of time living together, partners in closed relationships reported higher Affiliation/Dependency, more Favorable Attitudes toward the Relationship, and lower Tension than partners in open relationships. Global relationship quality for both types of couples was related to many Attractions, many Barriers, and few Alternatives to the relationship; few beliefs regarding both Disagreement is Destructive and Partners Cannot Change; high Dyadic Attachment; high Shared Decision Making; and low Psychological Maladjustment. Partners in both types of relationships were more similar to each other than different from each other, especially on the variables of Relationship Quality, a belief in Partner Changeability, and Dyadic Attachment.  相似文献

The total fertility rate of women of childbearing age of Dongguan County in China has been decreasing gradually from 5.9 during the period following the liberation in 1949 to 2.05 in 1982. In order to encourage young couples to implement the policy of family planning consciously, the people's government of Dongguan county decided in July 1980 that all cadres and employees in county towns who received 1-child certificates would be exempted from house rent of 45 square meters from the time they get their certificates and would be allocated a living space of a 2-children family until their children reached age 16. It also stipulated that every couple could enjoy 1 month's holiday every year for 3 years and during the holiday, their salary, bonus and rate of attendance would not be affected. Because women bear less children today, they are relieved from heavy household chores and become the main working force in collective production. As a result, the development of town-run enterprises was stimulated and the total industrial output value of these enterprises increased. The average monthly salary of each female worker is about 100 yuan. In 1984, the average income per capita of the country rose to 649.2 yuan. The implementation of family planning work has eased the tension in the education field. Previously, because of the large number of school-age children in rural areas, teachers had to teach 2 classes. In the past 4 years, great emphasis was laid on intellectual investment. During this period, 2351 schools were built and several fundraising projects were implemented. Since 1981, more than 200 new running water projects were built, and new public services have been developed, including old age homes.  相似文献

Both published results from the 1930, 1947, 1960 and 1971 censuses and unpublished ones are used to examine the influence that religious denomination, socio-economic group and region exerted on the fertility of marriages contracted between 1876 and 1959. A theory formulated by Lesthaeghe and Wilson on the relation between modes of production and secularization and the pace of fertility decline in Western Europe offers — in combination with van Heek's views on the special position of Dutch Roman Catholicism — a starting point for an explanation of why the fertility decline of Roman Catholics, self-employed and agricultural labourers lagged behind.  相似文献

USING DUAL FRAME DESIGNS TO REDUCE NONRESPONSE IN TELEPHONE SURVEYS   总被引:1,自引:0,他引:1  
This article reports on the results of a series of experimentsdesigned to improve response rates for telephone surveys. Inthree surveys telephone households were selected using bothstandard random digit dialing (RDD) techniques and lists oftelephone numbers purchased from a commercial firm. In the RDDportions of the samples "cold contact" interviewing methodswere used; in the list frame portions advance letters were mailed,and the listed household name was used in the introduction.Experiments were designed to test the effects on response ratesof the advance letters and use of the listed household nameas a means of establishing rapport. The advance letters increasedresponse rates, but no difference could be attributed to theuse of names. The mixture of RDD and list sampling techniquesis also used to evaluate the effects of relative response rateson substantive findings. The cost consequences of these dualframe designs are assessed along a number of dimensions, andthe cost and error components of these designs are discussed.  相似文献

The occupational distributions of the native-born and foreign-born in the Australian labor market differ greatly. The disparity between the occupational distributions is greatest among the middle age-bracket, and among immigrants from Eastern Europe and the Mediterranean region. Analysis of occupational attainment using unit record data from the 1981 Census shows that as duration of residence in Australia lengthens, the occupational distribution of the overseas-born converges toward that of the Australian-born. Moreover, birthplace groups differ in the degree of upward mobility associated with length of residence in Australia: immigrants from non-English-speaking countries tend to make greater occupational advances than their counterpart from English-speaking countries. This suggests a higher degree of international transferability of human capital skills among immigrants from English-speaking countries. The analysis also highlights the concentration of immigrants from non-English speaking countries in low-ranked occupations, and the relatively minor influence of education on the occupational attainment of immigrants from these birth place regions.  相似文献
