The paper extends Diamond's (1984) analysis of financial intermediation to allow for risk aversion of the intermediary. As in the case of risk neutrality, the agency costs of external funds provided to an intermediary are relatively small if the intermediary is financing many entrepreneurs with independent returns. Even though the intermediary is adding rather than subdividing risks, the underlying large-numbers argument is not invalidated by the presence of risk aversion.
With risk aversion of entrepreneurs as well as the intermediary, financial intermediation provides insurance as well as finance. In contrast to earlier results on optimal intermediation policies under risk neutrality, the paper shows that when an intermediary is financing many entrepreneurs with independent returns, optimal intermediation policies must shift return risks away from risk averse entrepreneurs and impose them on the intermediary or on final investors. 相似文献

The present paper reports the results of a vignette- and questionnaire-based research project investigating the influence of Moral Intensity (MI) on decision making in a New Zealand business context. The use of a relatively sensitive research design yielded results showing that – in contrast to previous research – objective manipulations, as well as subjective perceptions, of three of the six MI components were of particular importance in accounting for a comparatively large proportion of the variation in four outcome variables. There were no interactions of appreciable magnitude between MI components, or variations across scenarios. Also, no support was found for a reliable multi-dimensional structure of perceptions of Moral Intensity. Implications of the findings are discussed. 相似文献

The paper provides an extension and a new proof of Deaton's theorem on the undesirability of nonuniform excise taxation when income taxes are affine and preferences over consumption goods are separable from labour–leisure choices, homothetic, and identical across agents. 相似文献

In this study, we re-examine the relationship among interest rates on the long-term government bonds of five industrialized countries. Using both the variance ratio test and fractional cointegration analysis, we find significant evidence that indicates the five government bond rates are fractionally cointegrated. In specific, our results show that the error correction term of the system of the five interest rates follows a mean-reverting, fractionally integrated process. 相似文献

A possible definition of ill-posedness in statistical estimation is the lack of qualitative robustness. In this sense direct density estimation shares ill-posedness with the more obviously ill-posed indirect density estimation models, of which it is a special case. A general construction pattern for estimators is proposed, based on suitable preconditioning, that works for both direct and indirect density estimation. Special emphasis is on its application to the direct case, where in general it yields delta-sequence estimators. More specifically both kernel and series type estimators are included depending on the choice of preconditioning operator. In particular sinc and other flattop kernel estimators emerge in a natural way. 相似文献
