Extended enterprises face many challenges in managing the product quality of their suppliers. Consequently characterizing the quality risk posed by value‐chain partners has become increasingly important. There have been several recent efforts to develop frameworks for rating the quality risk posed by suppliers. We develop an analytical model to examine the impact of such quality ratings on suppliers, manufacturers, and social welfare. While it might seem that quality ratings would benefit high‐quality suppliers and hurt low‐quality suppliers, we show that this is not always the case. We find that such quality ratings can hurt both types of suppliers or benefit both, depending on the market conditions. We also find that quality ratings do not always benefit the most demanding manufacturers who desire high‐quality suppliers. Finally, we find that social welfare is not always improved by risk ratings. These results suggest that public policy initiatives addressing risk ratings must be carefully considered. 相似文献

College-educated Catholic women in the 1976 National Survey of Family Growth had higher actual and expected fertility than did college educated Protestants. Moreover, Catholic colleges or universities had a pronatalist effect on alumnae. Thus, a significant part of the higher Catholic than Protestant cumulative fertility among college-educated women arose from the greater propensity of such Catholics to attend sectarian schools and colleges. The implications are explored. 相似文献

This study analyzed one respondent per household who was age 70 or more at the time of the household's inclusion in Wave 1 (1993-1994) and whose survival status was determinable at Wave 2 (1995-1996) of the Survey on Asset and Health Dynamics Among the Oldest Old (AHEAD Survey). At age 76 at Wave 1, there was a racial crossover in the cumulative number of six potentially fatal diagnoses (chronic lung disease, cancer, heart disease, hypertension, diabetes, and stroke) from a higher cumulative average number for blacks to a higher average number for whites. Also, there was a racial crossover at age 86 in the cumulative average number of disabilities in the Advanced Activities of Daily Living (AADLs), from a higher average for blacks to a higher average for whites. Between Waves 1 and 2, there was a racial crossover in the odds of mortality from higher odds for blacks to higher odds for whites; this occurred at about age 81. The results are consistent with the interpretation that the racial crossover in comorbidity (but not the crossover in AADL disability) propelled the racial crossover in mortality. 相似文献

Evidence of group differences in reproductive control and access to reproductive health care suggests the continued existence of "stratified reproduction" in the United States. Women of color are overrepresented among people with infertility but are underrepresented among those who receive medical services. The authors employ path analysis to uncover mechanisms accounting for these differences among black, Hispanic, Asian, and non-Hispanic white women using a probability-based sample of 2,162 U.S. women. Black and Hispanic women are less likely to receive services than other women. The enabling conditions of income, education, and private insurance partially mediate the relationship between race-ethnicity and receipt of services but do not fully account for the association at all levels of service. For black and Hispanic women, social cues, enabling conditions, and predisposing conditions contribute to disparities in receipt of services. Most of the association between race-ethnicity and service receipt is indirect rather than direct. 相似文献

This study analyzes whether social support serves as a link to or substitute for formal services among African American female caregivers seeking help with emotional problems. It also analyzes other determinants of help-seeking. It relies on data from the Black Rural and Urban Caregivers Mental Health and Functioning Study and is guided by a modified version of the behavioral model of health services use. Using hierarchical binary logistic regression, analyses reveal that only age, stress, and support from fellow church members are statistically significantly associated with the likelihood of help-seeking. These results support the linking hypothesis, suggesting that the social support received by African American women caregivers in the context of their religious organizations helps to link them to services. 相似文献

Although several methods have been developed to allow for the analysis of data in the presence of missing values, no clear guide exists to help family researchers in choosing among the many options and procedures available. We delineate these options and examine the sensitivity of the findings in a regression model estimated in three random samples from the National Survey of Families and Households (n = 250–2,000). These results, combined with findings from simulation studies, are used to guide answers to a set of 10 common questions asked by researchers when selecting a missing data approach. Modern missing data techniques were found to perform better than traditional ones, but differences between the types of modern approaches had minor effects on the estimates and substantive conclusions. Our findings suggest that the researcher has considerable flexibility in selecting among modern options for handling missing data. 相似文献

We collect data from 162 replications of the Berg, Dickhaut, and McCabe Investment game (the “trust” game) involving more than 23,000 participants. We conduct a meta-analysis of these games in order to identify the effect of experimental protocols and geographic variation on this popular behavioral measure of trust and trustworthiness. Our findings indicate that the amount sent in the game is significantly affected by whether payment is random, and whether play is with a simulated counterpart. Trustworthiness is significantly affected by the amount by which the experimenter multiplies the amount sent, whether subjects play both roles in the experiment, and whether the subjects are students. We find robust evidence that subjects send less in trust games conducted in Africa than those in North America. 相似文献

A groundswell of interest in young people’s ability to understand and handle financial decisions has generated keen interest
in financial knowledge and effectiveness of financial education. This study examines an innovative four-year school-based
financial education and savings program, called “I Can Save” (ICS). Using a quasi-experimental design, the study examines
quantitative and qualitative data to analyze program effects on financial knowledge. Elementary school children who participated
in ICS scored significantly higher on a financial literacy test taken in fourth grade than comparison group students in the
same school, regardless of parent education and income. Results suggest that young children increase financial capability
when they have access to financial education and it is accompanied by participation in meaningful financial services. 相似文献
