We extend the analysis of risk aversion with state-dependent preferences to the rank-dependent expected utility theory. We find that in this extended theory, for two preference relations to be comparable in risk aversion not only do their reference sets need to coincide (a condition first introduced by Karni [1983, 1985] in the original expected utility framework), but they must also rank the prospective state-dependent outcomes in the same manner. We formalize this additional condition by introducing the concept of certainty sets. Under our condition of comparability, various results and characterizations of interpersonal comparison of risk aversion are obtained. The implications for a specific insurance problem are also discussed. 相似文献

The growing body of whistleblowing literature includes many studies that have attempted to identify the individual level antecedents of whistleblowing behavior. However, cross-cultural differences in perceptions of the ethicality of whistleblowing affect the judgment of whistleblowing intention. This study ascertains how Chinese managers/professionals decide to blow the whistle in terms of their locus of control and subjective judgment regarding the intention of whistleblowing. Hypotheses that are derived from these speculations are tested with data on Chinese managers and professionals (n = 306). Statistical analysis largely supports the hypotheses, which suggests that an individual's locus of control does moderate the relationship between ethical judgment and whistleblowing. 相似文献

A common concern about political decision making is that re-election concerns compel incumbent politicians to select policies that, although popular among the electorate, are inferior to available, less popular alternatives. Through studying a series of models, 1 find that, as long as politicians differ solely in the utility derived from holding office, there always exists an equilibrium where incumbents with strong re-election concerns still make efficient policy choices. However, when other aspects of heterogeneity among politicians are present, incumbents with strong re-election concerns may have the incentive to condition their decisions according to policy popularity. Suppose, for instance, some politicians are dumb in the sense that they are even more ignorant about policy efficacy than the public. To avoid being viewed as dumb, nondumb politicians (especially those with strong reelection concerns) may accept popular but inefficient policies or reject unpopular but efficient policies. 相似文献

In this study, we propose an optimal cash holding model which examines the tradeoff between illiquidity and opportunity cost concerns as the benchmark to determine corporate excess cash. Through an optimization process, the optimal cash holdings suggested by our illiquidity–opportunity tradeoff model (IOT model) are endogenously determined. Different from many prior studies, the IOT model not only contains the value of cash, through market-based conception, but also adopts the modified Black–Scholes–Merton default probability of illiquidity. We then compare the IOT model with the Opler et al. (J Financ Econ 52(1):3–46, 1999) model (the OPSW model), which is a widely-used benchmark to determine excess cash, by using data for U.S. public firms from 1984 to 2014. The empirical results show that with regard to financial management the IOT model could be a better alternative to determine excess cash, even in light of different corporate characteristics and performance measures. Our conclusion suggests that while exploiting the value of marginal cash has attracted the attention of many recent studies, exploring the issue of optimal cash holdings is still important in the literature. 相似文献

The contributions of this paper are threefold. The first contribution is the proposed logarithmic HAR (log-HAR) option-pricing model, which is more convenient compared with other option pricing models associated with realized volatility in terms of simpler estimation procedure. The second contribution is the test of the empirical implications of heterogeneous autoregressive model of the realized volatility (HAR)-type models in the S&P 500 index options market with comparison of the non-linear asymmetric GARCH option-pricing model, which is the best model in pricing options among generalized autoregressive conditional heteroskedastic-type models. The third contribution is the empirical analysis based on options traded from July 3, 2007 to December 31, 2008, a period covering a recent financial crisis. Overall, the HAR-type models successfully predict out-of-sample option prices because they are based on realized volatilities, which are closer to the expected volatility in financial markets. However, mixed results exist between the log-HAR and the heterogeneous auto-regressive gamma models in pricing options because the former is better than the latter in times of turmoil, whereas it is worse during the rather stable periods. 相似文献

In this paper, human capital in the form of ‘health status’ is introduced into a neoclassical economic growth model as one of the main factors differentiating rich and poor countries. Various panel data models are used to examine how health and other growth factors affect average income in different countries. Our main empirical finding indicates that a one-year increase in life expectancy (the health status measure) raises GDP per capita by 0.5–0.9%. Based on this result, a baseline health status can be established to help poor countries achieve a targeted economic growth rate. 相似文献

In this article, we use the data envelopment analysis to measure the efficiency of banks before and after credit rating is taken into consideration and we also employ the Malmquist Productivity Index to measure the total factor productivity changes from 2001 to 2003. The results are as follows: (1) There is a positive relationship between the efficiency scores and credit rating, and thus, the credit rating can be a representative to evaluate the performance and quality of a bank; (2) We use the Wilconxon two-sample test of nonparametric statistic to test the influences of credit rating. The empirical result shows that the credit rating is proven to influence the efficiency of banks; (3) The efficiency scores improve in both investment grade (above tw BBB?) and speculation grade (under tw BBB?), when credit rating is taken into consideration. The empirical results show that the efficiency scores of banks with a high credit rating improved relatively more when compared to banks with a lower credit rating; (4) In this research we also adopt the Malmquist index to observe the productivity and efficiency changes from year to year. We obtain results whereby the improvement of efficiency may be influenced greatly both from pure technical and scale efficiency changes. 相似文献

Macroeconomic fluctuations in interest rates, exchange rates, and inflation can be considered sources of good or bad “luck” for corporate performance if management is unable to adjust operations to these fluctuations. Based on a sample of 2,091 US firms, we decompose the impacts of macroeconomic fluctuations on three measures of CEO compensation. Our study provides empirical support for the importance of considering macroeconomic fluctuations in designing CEO incentive schemes. It adds to the managerial power literature on moral hazard and CEO compensation by pinpointing the obvious risk that the CEO in an asymmetric and non-linear reward system will be inclined to prioritize his/her own cash flow at the expense of fulfilling an assumed agency role. The policy conclusion for remuneration committees and board of directors is to filter out macroeconomic influences on performance to be rewarded whenever an asymmetric compensation scheme has been opted for. 相似文献

This study adopts a three-stage approach to estimate bank efficiency based on information obtained from 29 banks in Taiwan for the period from 2002 to 2004. In the first stage we employ super SBM (super slacks-based measure) to estimate the scores relating bank efficiency including internal risk. In the second stage a stochastic frontier regression model is then employed to estimate the external environment risk effects. In the third stage we employ the DEA method again to estimate the scores relating bank efficiency including the internal risk and excluding the external risk. 相似文献

Mean-downside-risk and mean-variance newsvendor models: Implications for sustainable fashion retailing 总被引:2,自引:0,他引:2
Tsan-Ming ChoiChun-Hung Chiu 《International Journal of Production Economics》2012,135(2):552-560
Newsvendor models have been well-established for studying supply chain management problems with fashionable products. In this paper, we explore the mean-downside-risk (MDR) and mean-variance (MV) newsvendor models under both the exogenous and endogenous retail price decision cases. We first construct analytical models with the MDR and MV objectives. We then show that the analytical solution schemes for both the MDR and MV problems are the same. With the measures for sustainability such as the expected quantity of goods leftover, the expected sales to expected goods leftover ratio, the rate of return on investment, and the probability of achieving a pre-determined profit target, we proceed to compare the levels of sustainability by the fashion retailers which employ the mean-risk and the risk neutral models. Insights are generated. 相似文献
