From the expected‐utility approach, relative risk aversion being smaller than one and relative prudence being smaller than two emerge as preference restrictions that fully determine the optimal responses of decisions under uncertainty to certain shifts in probability distributions. We characterize the magnitudes of relative risk aversion and relative prudence in terms of the two‐parameter, mean‐standard deviation approach. We demonstrate that this characterization is instrumental in obtaining comparative static results in the two‐parameter setting. We further relate our findings to the results in the expected‐utility framework. 相似文献

This study examines the long‐run relationship between the real effective exchange rate and its fundamental determinants, and derives a real effective equilibrium exchange rate for the Swedish krona. Our results indicate that the krona was severely overvalued in late 1992, when the fixed exchange rate regime was abandoned. By the end of 2000 the krona was undervalued by approximately 5 percent, given the prevailing economic conditions. Arithmetic examples of suitable SEK/EUR conversion rates are calculated under various assumptions to provide a guideline if Sweden were to adopt the euro in the future. 相似文献

服务业集聚与产业结构优化关系探究 总被引:3,自引:0,他引:3
随着全球化进程的不断加快,服务业集聚已经成为人们普遍关注的话题。产业集聚在获得规模效应的同时避免了垄断现象的产生,服务业集聚不但拥有这样的优势,而且还有自己独特的形成和发展特点。从产业结构的优化角度切入,借助区位商和专门化率等分析指标,以江苏省和上海市为例,对服务业集聚的形成进行理论和实证分析,提出产业结构的优化对于服务业集聚的形成和发展有着积极的作用。合理的产业结构能够为服务业集聚提供坚实的基础,各地区应该根据各自的产业特点积极的进行优化,催生服务业集聚,加快本地区经济的进一步发展。 相似文献

Abstract: The relationship between past net asset value returns and the current discount on investment trusts is investigated. The relationship is weaker for the component that is common to all trusts in the same sector, and is significantly stronger for more liquid trusts. The time lag before returns have their full impact on discounts is consistent with the requirements of distinguishing 'skill' from noise. Although discounts vary widely even within the same sector, the range of variation appears to be consistent with an arbitrage equilibrium, in which the profits of exploiting apparent pricing anomalies are just insufficient to invite arbitrage trades. 相似文献

We empirically investigate the interactions among hedging, financing, and investment decisions. We argue that the way in which hedging affects a firm's financing and investing decisions differs for firms with different growth opportunities. We find that high growth firms increase their investment, but not leverage, by hedging. However, we also find that firms with few investment opportunities use derivatives to increase their leverage. 相似文献

The study examines the aggregate dividend behavior of U.S. corporations based on the permanent earnings hypothesis. Using annual data of aggregate earnings and dividends from 1871–1993, I find that although managers change dividends proportional to permanent earnings changes, they make revisions with a larger percentage change in dividends than in permanent earnings. The results from the post‐war data show that firms follow a partial adjustment policy with a long‐term dividend payout target in mind and make revisions with a delay. The quarterly data analysis yields results similar to those of the post‐war annual data. 相似文献

An interest charge is made up of an award for waiting known as the real rate of interest, a premium for risk and compensation for transaction costs. Where inflation exists the lender seeks further compensation. In order to understand the composition and evolution of different versions of the usury prohibition it is necessary to ask which components of an interest charge are prohibited by each version. The Judaic prohibition has two aspects which are of particular interest to business historians and students of usury. First, the general rule is that a reward for waiting is prohibited. This focuses on the time-based part of interest charge. Second, interest is prohibited because it amounts to placing a stumbling block before the blind. This focuses on the typical gullibility of the borrower confronted by a more expert, better funded lender. Economics confirms and enriches our understanding of these important aspects of the prohibition. They achieve this by increasing our understanding of two facts: first, that the borrower is a gullible individual subject to irrational and inconsistent behaviour; and, second, that this behaviour relates to the waiting aspect of interest which is proscribed in the prohibition. How far these insights apply to other civilisations' prohibition, particularly those which derive from the Judaic prohibition, merits further study; so also do the ethical lessons of the Mosaic rules for a globalised society based on capitalism. 相似文献

This essay proposes the concrete view that China's strategy of utilizing foreign capitals to adjust again on the foundation of explaining new characteristics of international capital circulation, namely, expanding the foreign investments of the service trade, strengthening efforts to attract outside investment of the Midwest, attracting trans-corporation's investment, etc., Chinese enterprises actively move towards overseas investment and create the policy environment that can contribute to absorbing the foreign capitals as well as making national economy benefit from it. 相似文献
