This paper studies a single-product distribution channel where a supplier manufactures items of a given type, some of which are defective, that are sold by a retailer who only detects a subset of the defective items, passing the rest along to customers. We conjecture the structure of the demand and cost functions, assuming customers to have a decreasing marginal aversion to bad quality while both the supplier and the retailer make marginally increasing efforts to avoid bad quality. This allows us to deduce several implicit parameters of a cost model based on observable data, such as the share of the channel margin. Once the parameters of the model are available, we analyze the result of vertical integration. Although we confirm the well-known fact that vertical integration improves the quality perceived by the customer, we characterize the supplier's decision of whether or not to provide a better quality in terms of the individual channel margins. As an alternative, we derive the conditions under which the supplier and the retailer may devise a mutually beneficial transfer contract that simultaneously increases their profit and improves quality. 相似文献

This paper reviews changes in homogamy by migration status and educational level in Monterrey, Mexico, through the analysis
of marriage patterns for two cohorts of men born in 1905–1934 and 1940–1969. Results show a significant increase in educational
homogamy, as well as in homogamy by rural origins. The changes suggest that education has played an increasingly important
role in the process of mate selection, although certain particularistic characteristics, such as being a rural immigrant,
are still important in marriage formation. The paper concludes with a discussion of the implications of these findings for
the relationship between homogamy and social stratification.

This article presents the results of a preliminary trial, in the context of an intervention, developed by a team of ergonomists under the request of the Occupational Health Department of the General Management of Schools in the Province of Buenos Aires, Argentina. We present a reformulation of the request and the results obtained in 2009 from observations and interviews held in three schools in the province of Buenos Aires in which different jobs positions were assessed. From this stage onwards, the tools were validated and new aspects were shown, particularly in relation to the high variety of real situations in the education sector. 相似文献

A macro-scale methodology for vehicle emissions estimation is described. The methodology is based on both correlations between
activity level and PM, CO, THC and NO
x
vehicle emissions and relationships between demographic and socio-economic variables and transportation activity level. First,
pollutant emissions were correlated with transportation activity, expressed as vehicle-km/year, using existing data collected
from mobile sources emission inventories in nine urban cities of Chile. Second, demographic and socio-economic variables were
pre-selected from those that could intuitively be correlated with vehicle activity level and considering the data availability.
Using the individual R
2 correlation coefficient as variable selection criterion, population, the number of vehicles, fuel consumption, gross domestic
product, average family incomes and road kilometers were finally chosen. A different set of explicative variables was considered
for different vehicle categories, based on the selection criterion above mentioned. Then, correlation functions between these
variables and transport activity were obtained by non-linear Gauss–Newton least square method. This methodology was applied
to eighteen provinces of the country obtaining total annual emission for mobile sources, divided into six main vehicles categories. 相似文献

Most demographic studies use 2,500 grams of birth weight and 37 weeks of gestation as cutpoints for evaluating the effects of adverse birth outcomes on infant mortality. We propose an alternative strategy, which relies on continuous measures of birth outcomes, identifies an optimal combination of birth weight and gestational age for infant survival, and estimates the effects of adverse birth outcomes in terms of their departure from this "optimal point." We illustrate the advantages of this approach by estimating a logistic model using data from the 1989-1991 NCHS linked birth/infant death files. Finally, we discuss future applications and methodological issues to be resolved in subsequent research. 相似文献

We develop a model of decision-making with endogenous frames and contrast the normative implications of our model to those
of choice theoretic models in which observed choices are determined by exogenous frames or ancillary conditions. We argue
that, frames, though they may be taken as given by the decision-maker at the point when choices are made, matter for both
welfare and policy purposes. 相似文献

Perceived parental knowledge and adolescents' disclosure to parents were predicted from parental warmth and monitoring and adolescents' disclosure, agreement, and beliefs about obligation to obey and parental legitimacy (N=698 Chilean, Filipino, and U.S. 13–20‐year‐olds). The correlates of knowledge are similar in all three countries, but the relative strength of the correlations differs. Global agreement was associated with greater knowledge. Parents knew most about issues governed by rules and those where adolescents agreed, felt obliged to obey, and disclosed. Monitoring predicted knowledge only in Chile and the Philippines. Warmth was a stronger predictor of knowledge in the United States. Key predictors of disclosure include agreement in Chile, agreement and rules in the Philippines, and warmth and rules in the United States. 相似文献
