We develop a model in which individuals compete for a fixed pool of prizes by investing effort in a contest. Individuals belong to two separate and identifiable groups. We say that the contest is discriminatory if a lower share of prizes is reserved for one group than for the other. We show that it can be difficult for an observer to detect the presence or absence of discrimination in the contest, as both regimes can be observationally equivalent. In particular, one group’s belief that it is allocated a lower share of prizes than the other group can be consistent with observed data even if no such group quotas actually exist. Conversely, the belief that the contest does not discriminate can be consistent with data when, in fact, discrimination exists. Incorrect beliefs will therefore not be revised, as the contest generates no evidence to the contrary.  相似文献

This study examines the expense ratio policy of Greek equity funds operating in a small emerging market with an oligopolistic, bank-dominated financial system. Constructing a unique dataset of non-publicly available expense ratios charged by these funds, we examine the impact these expenses have on funds’ performance and flows. The main conclusion is that funds’ performance is negatively related to their expenses, while investors’ flows are not directly affected by expenses. Furthermore, the funds affiliated with one of the three dominant domestic banking groups achieve higher performance and attract higher net flows in comparison to their competitors.  相似文献

Using daily return data from 448 actively managed mutual funds over a recent 9-year period, we look for persistence, over two consecutive quarters, in the ability of funds to select individual stocks and time the market. That is, we decompose overall fund performance into excess returns resulting from stock selection and timing abilities and we separately test for persistence in each ability. We find persistence in the ability to time the market only among well performing funds and in the ability to select stocks only among the very best and worst performers. The existing literature patterns appear only when funds are ranked by their overall performance, which includes stock selection, market timing and fees. With respect to overall performance, there is persistence among most poorly performing and only the top well performing funds. Furthermore, the profitability of a winner-picking strategy depends on the rebalancing frequency and potentially the size of the investment. Small investors cannot profit, whereas large investors can take advantage of the class-A share fee structure and realize positive abnormal returns by annually rebalancing their portfolios.  相似文献

Multiple-job holding is an important labour market phenomenon. In this article, we examine individuals’ motives for multiple-job holding. Specifically, we estimate an empirical model of the motivation for moonlighting assuming that individuals hold a second job for either financial or for nonpecuniary motives. Our results contribute to a better understanding of multiple-job holding. We find that multiple-job holding is used by individuals as a way to deal with the financial difficulties or the increased financial commitments in their household. Individuals are more likely to moonlight for money in the early stages of their adult life. Finally, individuals with more labour market experience are more likely to moonlight for pecuniary than nonpecuniary reasons.  相似文献

This paper examines the response of US stock returns to Federal Funds rate (FFR) surprises between 1989 and 2012, focusing on the impact of the recent financial crisis. We find that outside the crisis period, stock prices increased as a response to unexpected FFR cuts. State dependence is identified with stocks exhibiting larger increases when interest rate easing coincided with recessions, bear markets, and tightening credit conditions. However, an important structural shift occurred during the crisis, changing the stocks’ response to FFR shocks and the nature of state dependence. Throughout the crisis period, stocks did not react positively to unexpected FFR cuts, which were interpreted as signals of worsening future economic conditions. This triggered a rebalancing of investment portfolios away from falling equities and towards safe-haven assets. Our results highlight the severity of the crisis and the ineffectiveness of conventional monetary policy close to the zero lower bound.  相似文献

The examination for the possible existence of predictive power in the moving average trading rule has been used extensively to test the hypothesis of weak form market efficiency in capital markets. This work focuses mainly on the study of the variation of the moving average (MA) trading rule performance as a function of the length of the longer MA. Empirical analysis of daily data from NYSE and the Athens Stock Exchange reveal high variability of the performance of the MA trading rule as a function of the MA length and on some occasions the series of successive trading rule total returns is non‐stationary. These findings have direct implications in weak form market efficiency testing. Indeed, given this high variability of the performance of the MA trading rule, by just finding out that trading rules with some specific combinations of MA lengths can or cannot beat the market, as is the case in most of the published work thus far, is not enough evidence for or against the existence of weak form market efficiency. Results also show that on average in about three out of four cases trading rule signals are false, a fact that leaves a lot of space for improved trading rule performance if trading rule signals are combined with other information (e.g. filters, or volume of trade). Finally, some evidence of enhanced trading rule performance for the shorter MA lengths was found. This enhanced performance is partly attributed to the higher probability that a trading rule signal is not a whipsaw, as well as to the larger number of days out‐of‐the‐market which are associated with shorter MA lengths.  相似文献

Companies whose names contain the words “America(n)” or “USA” earn positive abnormal returns of about 6% per annum during World War II, the Korean War, and the War on Terrorism. These abnormal returns are not realized immediately upon the outbreak of each of the wars but are accumulated gradually during wartime. Given that no such effect is observed for the Vietnam War, we hypothesize that major, victorious wars arouse investors' patriotic feelings and cause them to gradually and perhaps subconsciously gravitate toward stocks whose name has a patriotic flavor.  相似文献

The Pricing of Equity Carve-Outs   总被引:1,自引:0,他引:1  
This article examines the pricing of stock for 251 equity carve‐outs during the 1986–1995 period. We document a mean initial‐day return of 5.83% and a mean one‐week return of 5.43%. Among carve‐outs, the initial underpricing is lower for issues represented by high prestige investment bankers and those that have a lower offer price. In comparison with 251 initial public offering (IPO) firms matched by size and book‐to‐market ratio of equity, carveouts exhibit significantly lower initial‐day returns, but their buy‐and‐hold returns for sixmonth and one‐year periods are not significantly different from IPOs. The IPO firms have a three‐year return of 28.82% which is significantly higher than the 21.07% return for the carve‐out firms.  相似文献

In this paper the effect of inflation on firms' investment and debt-financing decisions is examined. Inflation affects optimal investment and financing directly through the probability of accounting loss and the real value of depreciation and interest tax shields. In addition, when corporate and differential personal taxes cause investment and financing decisions to interact, inflation has indirect effects on these decisions through their interactions. In general, the overall effects of inflation on optimal investment and debt are ambiguous in sign. For tax-exempt firms, however, optimal investment and debt are independent of inflation. For firms that are always in a tax-paying position, higher inflation reduces optimal investment without affecting optimal debt. Furthermore, inflation causes total firm value to decrease if the depreciation rate exceeds the firm's debt/asset ratio.  相似文献

In this paper we examine empirically the predictive power of model‐free option‐implied variance and skewness in wheat, maize and soybeans derivative markets. We find that option‐implied risk‐neutral variance outperforms historical variance as a predictor of future realised variance for these three commodities. In addition, we find that risk‐neutral option‐implied skewness significantly improves variance forecasting when added in the information variable set. Variance risk premia add significant predictive power when included as an additional factor for predicting future commodity returns.  相似文献
