The bank lending channel implies the Federal Reserve can influence real income by controlling the level of intermediated loans. Using the notion of causality developed by Simon (1953) and the causal order methodology developed by Hoover (1990), I test for an operative bank lending channel in the transmission mechanism of monetary policy. I find loans did cause real income; there is evidence that a bank lending channel did exist in the 1960s. The data appears to show, however, that by the early 1990s the bank lending channel was no longer operative. © 1998 John Wiley & Sons, Ltd. 相似文献

Using 1971–90 panel data from a Siberian province, two econometric methods are used side by side to examine technical inefficiency with a suggestion as to how the methods might be used in sequence. Estimates derived from a random effects method reveal that technical inefficiency is both substantial and not time invariant. Results using either a random or fixed effects method suggest that existing estimates of technical inefficiency in centrally planned economies may be biased downward because of the choice of the estimation method. Using either method, the increasing technical inefficiency found is likely to be one cause of the decline in the performance of centrally planned economies and their regions. 相似文献

该文构建非对称信息模型分析普遍服务政策问题,其中政府对企业在农村提供服务的边际成本具有非对称信息.该文对区别定价和统一定价两种情形进行了对比分析.在实施区别定价时,不完全信息将提高农村地区的资费水平,并且降低相应的网络覆盖面积;而在实施统一定价时,农村地区的定价可能降低,但却是以网络覆盖的减少为代价的.该文的政策结论是:在实施普遍服务政策时,需要综合考虑网络投资的激励和用户承受能力. 相似文献

Altruism is a type of non-use value which can have different definitions depending on the type of goods entering the utility function of the altruists and their expectations about the contributions of others. The purpose of this paper is to measure the trade-offs between different types of altruist values originating from social and environmental policies. Environmental policies are concerned with reducing health effects from a power plant while social policies involve both the attainment of public facilities for education and leisure and an increase in the income of the affected population. The empirical application utilizes a choice experiment technique which allows for valuation of multiple goods. Health effects are decomposed into the values of the risk of becoming ill, the duration of the episodes and the limitations imposed by illness. Altruist values are elicited from a population that is not affected by pollution. Results show that altruism is significant for policies directed to reducing health effects and improving the income level of the affected population, whereas there is egoism for a policy aimed at improving public facilities in the polluted suburb. The value of altruism is significantly influenced by the expectations of net benefits to be received by the affected population. 相似文献

Money, Sex and Happiness: An Empirical Study 总被引:2,自引:0,他引:2
The links between income, sexual behavior and reported happiness are studied using recent data on a sample of 16,000 adult Americans. The paper finds that sexual activity enters strongly positively in happiness equations. Higher income does not buy more sex or more sexual partners. Married people have more sex than those who are single, divorced, widowed or separated. The happiness‐maximizing number of sexual partners in the previous year is calculated to be 1. Highly educated females tend to have fewer sexual partners. Homosexuality has no statistically significant effect on happiness. 相似文献
