This paper is concerned with differences in the performance-flow relationship (PFR) between standard and specialist market segments of the mutual fund industry. We expect differences in this relationship because investor characteristics might vary across different segments. Our results show that the PFR is more convex in standard segments than in specialist segments. Furthermore, investors in standard segments are less risk-averse and invest more in high-load funds than investors in specialist segments. Our findings are consistent with investors in standard segments being less sophisticated than investors in specialist segments and relying more heavily on the advice of financial brokers, which is compensated for by load fees. 相似文献

Summary Is the use of fiat money essential in any efficient organization of exchange? We investigate this question in economies that are generalizations of the Townsend (1980) turnpike model that include limited commitment and differential information. We show that in the Townsend turnpike model fiat money is not essential unless there is limited commitment. Furthermore, fiat money has no role whenever there is storage with positive returns. In the presence of differential information fiat money is essential in overcoming incentive problems. This is the case even if there is storage with positive returns.We wish to thank Bart Taub, Anne Villamil and seminar participants at the University of Chicago, the Federal Reserve Bank of Minneapolis, Ohio State, the 1994 North American Summer Meeting of the Econometric Society, SEDC 1994, and Oberwolfach 1994. 相似文献

This paper examines the geographic determinants of firm bankruptcy. We employ hazard rate models to study the bankruptcy risk
of a firm, allowing for time-varying covariates. Based on a large sample from all geographic areas and the major sectors of
the Swiss economy, we find the following main results: (1) Bankruptcy rates tend to be lower in the central municipalities
of agglomerations; (2) bankruptcy rates are lower in regions with favorable business conditions (where corporate taxes and
unemployment are low and public investment is high); (3) private taxes and public spending at the local level have little
impact on bankruptcy rates. 相似文献

We study the predictive ability of individual analyst target price changes for post-event abnormal stock returns within each recommendation category. Although prior studies generally demonstrate the investment value of target prices, we find that target price changes do not cause abnormal returns within each recommendation level. Instead, contradictory analyst signals (e.g., strong buy reiterations with large target price decreases) neutralize each other, whereas confirmatory signals reinforce each other. Further, our analysis reveals that large target price downgrades can be explained by preceding stock price decreases. However, upgrades are not preceded by stock price increases, thereby demonstrating asymmetric analyst behavior when adjusting target prices to stock prices. Our results suggest that investors should treat recommendations with caution when they are issued with large contradictory target price changes. Thus, instead of blindly following a recommendation, investors might put more weight on the change in the corresponding target price and consider transaction costs. 相似文献

We introduce a model for stock prices consisting of a fundamental price process and a news impact curve, which allows for either overreaction, underreaction, or correct response to changes of the fundamental value. We further develop statistics based on OHLC data, which separately measure upside and downside overreaction. The distribution of these statistics under the hypothesis of correct response and fundamental prices following Brownian motions is used to derive tests for upside and downside overreaction. We show that more realistic and frequently used fundamental price processes with correct response leave the distribution of the test statistics widely unaffected or lead to conservative tests. Empirical application to different stock markets provides strong evidence for intraday overreaction, particularly to bad news. The economic significance of the discrimination induced by the proposed statistics is further illustrated by analyzing the performance of a simple buy on bad news strategy. 相似文献

This paper examines the empirical properties of hedge fund returns and proposes a fully parametric model capable of adequately
describing both univariate and multivariate return properties. The suggested model is based on the multivariate extension
of the Normal Inverse Gaussian (NIG) distribution and will be shown to be capable of capturing the characteristic distributional
features of hedge fund returns. Drawing on recent research in the area of Generalized Hyperbolic distributions and their calibration,
we will elaborate on the application of the NIG-model for risk management purposes, and highlight the differences between
the NIG and the Gaussian model.
