We examine whether the use of the three‐moment capital asset pricing model can account for liquidity risk. We also make a comparative analysis of a four‐factor model based on Fama–French and Pástor–Stambaugh factors versus a model based solely on stock characteristics. Our findings suggest that neither of the models captures the liquidity premium nor do stock characteristics serve as proxies for liquidity. We also find that sensitivities of stock return to fluctuations in market liquidity do not subsume the effect of characteristic liquidity. Furthermore, our empirical findings are robust to differences in market microstructure or trading protocols between NYSE/AMEX and NASDAQ. 相似文献

On the existence of pure strategy Bertrand equilibrium 总被引:1,自引:0,他引:1
Krishnendu Ghosh Dastidar 《Economic Theory》1995,5(1):19-32
Summary The paper analyses the existence of pure strategy Nash equilibrium in price competition (or Bertrand equilibrium) in a homogeneous product market when costs are strictly convex and proves that if output is demand determined such equilibrium always exists. This paper also characterises such equilibria and shows that if firms are identical such equilibria are necessarily non-unique. However for firms with asymmetric costs it can be unique or non-unique.I am greatly indebted to Anjan Mukherji and Kunal Sengupta for this paper. I also express my profound gratitude to a referee of this journal for a very helpful set of suggestions. 相似文献

On Stackelberg games in a homogeneous product market 总被引:2,自引:0,他引:2
Krishnendu Ghosh Dastidar 《European Economic Review》2004,48(3):549-562
In a homogeneous product duopoly with concave demand and strictly convex costs we bring together all the standard results of quantity Stackelberg games, provide some new results with price Stackelberg games and compare the equilibrium configuration of the quantity games with the price games. In the price Stackelberg game we show there is a unique SPNE where the leader chooses a lower price than the follower, but both get equal payoffs. We prove that generally quantity Stackelberg games are less competitive than price Stackelberg games. However, we also demonstrate the possibility of a reversal of this result. 相似文献

In this article, the traditional price change hedge ratio estimation method is extended by applying the theory of cointegration in the case of cross-hedging of spot exchange risk of the Belgian franc (BF), the Italian lira (IL), and the Dutch guilder (NG) with U.S. Dollar Index futures contracts. Previous studies ignore the last period's equilibrium error and short-run deviations. The findings of this study indicate that the hedge ratio estimated by the error correction method is superior to that obtained from the traditional method, as evidenced by the likelihood ratio test and out-of-sample forecasts. Hedgers will be able to control the risk of their portfolios more effectively at a lower cost. 相似文献

We test the performance and interaction between earnings and price momentum for European real estate companies by first making use of decile portfolios sorted on the previous 3- to 12-month returns, standardized unexpected earnings and a combination of both. Then, the relation is tested on a risk-adjusted basis employing a 3-factor asset pricing model and Fama and Macbeth (1973) cross-sectional regression analyses. Our analyses reveal several critical findings: (1) both price and earnings momentum are effective for European firms, the effect being stronger for the UK than EU firms; (2) unlike U.S. REITs, price momentum seems to dominate drift for European firms; (3) there is weak evidence for positive interaction between drift and price momentum, contrary to the U.S. evidence; (4) the performance of momentum strategies depends on the state of the economy, while controlling for systematic factors; (5) idiosyncratic risk of real estate property firms may influence the returns on drift and momentum factors. 相似文献

We extend promotion signaling theory to generate new testable implications concerning racial differences in promotions. In our model, promotions signal worker ability. When tasks differ substantially across job levels, the opportunity cost of not promoting qualified non‐whites/non‐Asians is large, so employers are less likely to inefficiently withhold their promotions. Thus, given prepromotion performance, the extent to which non‐whites/non‐Asians have lower promotion probabilities decreases when tasks vary more across levels. Racial differences in wage increases at promotion diminish when tasks vary more across levels. Evidence from a single firm's personnel records supports the model's predictions concerning promotion probabilities. 相似文献

In a stratified sample, when sampling is done with replacement in each stratum a better estimate of the population mean can
be achieved by considering the distinct units only. An explicit expression for the variance for the mean, of a stratified
sample based on the distinct units only, is obtained. Then the optimum allocation for the different stratum are obtained by
minimizing this variance subject to (i) total sample size being fixed, or (ii) the expected number of distinct units being
fixed. Neyman’s solutions are obtained as special cases. The solutions finally arrived at are algebraically complex, hence,
numerical methods are applied. In all examples, the variance of the estimates obtained by this method are smaller than the
variances obtained by Neyman’s allocation.
