There is currently much debate in the economic literature about whether ethical investment involves a financial sacrifice or premium. One of the most common methods of testing this compares the financial performance of ethical investment funds with that of other funds not considered “socially responsible” or ethical. The majority of these research studies evaluate the performance of the ethical funds according to classic measures, whereby different financial markets, in different countries and for different periods of time serve as reference for evaluation. The ultimate conclusion of all of these studies is that there are no significant differences between the performance results of one type of funds and the other. In Spain, ethical investment funds are still an incipient sector of investment. To date, the Spanish market has not been included in any type of analysis of these characteristics. Therefore the main objective of this article is to compare the financial performance of ethical investment funds to that of other funds in the Spanish retail market. We propose the aggregate type of analysis as the Spanish ethical investment funds have experienced a weaker development in comparison to those of other developed countries. In the first step we suggest the financial performance to be compared by style analysis since the asset distribution of the Spanish Social Return Investment (SRI) funds differs from the European trend. In particular, we use the multifactor regression model with style benchmarks. We found that their financial performance is in all cases superior or similar to that achieved by the rest of the funds. In the second step, to achieve a more robust and homogeneous comparison, we used the bootstrap method, comparing ethical and non-ethical fund subsamples by homogeneous groups. No significant differences between these two types of funds have been found. Thus, if we assume the positive o neutral effect of ethical investment on investor utility in the retail Spanish market the financial and social performance (FSP) of ethical funds will be, in aggregate, superior to the FSP achieved by conventional funds. In conclusion, the financial performance of ethical mutual funds in Spain is no sacrifice.  相似文献

Abstract:  Using a proprietary data set to study how past performance affects the determinants of mutual fund flows for a sample of load fund investors, I provide evidence that the determinants of fund flow depend on market conditions for both redemptions and purchases. Specifically, I show that, for redemptions, relative performance and risk adjusted performance are important determinants during a period of record flows into mutual funds. Conversely, during a period of poor performance, absolute performance becomes much more important and relative performance and risk adjusted performance become less important. For purchases, absolute performance, risk adjusted performance, and most relative performance measures become more important during the bear market.  相似文献

We consider a general equilibrium model with individual and collective risks. The article builds on a contribution by Chichilnisky and Heal, who show that contingent Arrow–Debreu equilibria can also be supported in economies with Arrow securities and mutual insurance contracts. However, they show this to be true in general only if beliefs are identical, a very restrictive assumption in the context of unknown risks. Moreover, they claim complete insurance in equilibrium to be impossible if beliefs are different. We show that even with different beliefs, firstly, complete insurance is possible in each statistical state, and secondly, contingent equilibrium can still be supported in economies with insurance and securities.  相似文献

Research on pricing, profits, and firm survival has shown that multimarket contact causes mutual forbearance against competition, but has not considered the consequences of imperfect observability of competitive moves. Here, predictions are developed to explain how mutual forbearance occurs—but sometimes fails—in markets with imperfect observability. Mutual forbearance means that firms do not seek to take market share from each other through price cuts or nonprice competition, and thus that sales grow at uniform rates. Firms defect from mutual forbearance, and hence have higher sales growth, if the potential rewards are high and the likelihood of being discovered is low. This theory is tested on a panel of firms operating in the Norwegian general insurance industry. The evidence suggests that sales growth is most rapid in firms that do not meet many multimarket competitors in a given market and firms that are economically troubled. Growing or highly concentrated markets have higher heterogeneity of growth rates. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献
