Multivariate density estimation (MDE) suggests that mortgage-backedsecurity (MBS) prices can be well described as a function ofthe level and slope of the term structure. We analyze how thisfunction varies across MBSs with different coupons. An importantfinding is that the interest rate level proxies for the moneynessof the option, the expected level of prepayments, and the averagelife of the cash flows, while the term structure slope controlsfor the average rate at which these cash flows should be discounted.  相似文献

This article presents the results of a survey among German media supervisors (members of supervising boards in public broadcasting stations and state media institutions). Given the increasing commercialization and internationalization of television, the supervising boards play a crucial part in assessing the quality of programs. From among 940 German supervisors, 364 took part in the survey, which covered the individual role conceptions of respondents as well as their attitudes towards quality criteria for television. Results suggest that both the supervisors’ amount of television use and the types of programs they prefer is clearly different from patterns in the population. This, along with the observation that supervisors often criticize what they saw privately, suggests (given the diversity of programs) that too much might be expected of them. Media supervisors do heed quality criteria in their work, but these probably do not correspond to other groups’ criteria, and especially not to the general population’s. To conclude, suggestions are discussed to improve the system of supervising programs by important social groups.  相似文献

Methods of interrelated forecasting of the regional outputs of individual branches, household income, and consumption are considered. The instrument for the analysis and prediction for the parameters of the region’s economic system is a closed input-output model based on endogenous indicators of household income and demand.  相似文献

Summary The labour force participation of married women and the presence of young children in the family show a strongly negative correlation. In this article it is investigated whether this correlation is a reflection of a causal relationship between these two variables. To answer this question, a simultaneous logit analysis, following Mallax, is applied to data of the Dutch census of 1971 that are grouped by COROP region. The results suggest that there exists an asymmetric causal relationship between both variables with the causality running from the labour force participation of married women to the presence of young children in the family.The authors are indebted to Professors C. de Galan and C.K.F. Nieuwenburg and Mr. F.A.A.M. van Winden for valuable comments.  相似文献
