Mutual fund attrition can create problems for a researcher becausefunds that disappear tend to do so due to poor performance.In this article we estimate the size of the bias by trackingall funds that existed at the end of 1976. When a fund mergeswe calculate the return, taking into account the merger terms.This allows a precise estimate of survivorship bias. In addition,we examine characteristics of both mutual funds that mergerand their partner funds. Estimates of survivorship bias overdifferent horizons and using different models to evaluate performanceare provided.  相似文献

Are Investors Rational? Choices among Index Funds   总被引:3,自引:0,他引:3  
S&P 500 index funds represent one of the simplest vehicles for examining rational behavior. They hold virtually the same securities, yet their returns differ by more than 2 percent per year. Although the relative returns of alternative S&P 500 funds are easily predictable, the relationship between cash flows and performance is weaker than rational behavior would lead us to expect. We show that selecting funds based on low expenses or high past returns outperforms the portfolio of index funds selected by investors. Our results exemplify the fact that, in a market where arbitrage is not possible, dominated products can prosper.  相似文献

In many countries around the world, support for local agriculture has been a burgeoning issue involving the development of the local foods movement as an alternative marketing. This study investigated ethnic and geographic differences with respect to the consumers' perceptions of local foods in Indonesia. Semistructured interviews were conducted to examine consumers' views of local foods. “Location,” “quality,” and “price” were found to be the most salient characteristics of local foods. The idea of village was associated with the meaning of “local.” Although the respondents' levels of awareness of local foods were high, further education and dissemination of the national policy on local foods was urgently needed.  相似文献

This paper examines consumption patterns of urban households in China using aggregated household consumption data. A demand system comprising six commodities (rice,pork,vegetables,fish,eggs and fruits) is estimated using a two-stage budgeting procedure which incorporates an almost ideal deamnd system (AIDS) in each stage, Elasticity estimates from the system are plausible and consistent with other relevant studies. Results from this study strengthen the evidence of the emergence of a large Chinese market for non-stable food. The study provides rationale and basis for additional research into Chinese food consumption, especially processed food.  相似文献

Electronic government innovations have been a critical development in public administration in recent years. Many countries have implemented e-government policies to enhance efficiency and transparency and combat corruption. This paper examines the impact of e-government on corruption using longitudinal data for more than 170 countries from 2002 to 2020. The empirical results suggest that e-government serves as a deterrent to corrupt activities. We analyse which e-government domains affect corruption, which types of corruption are more affected by e-government and the circumstances under which e-government is more effective in reducing corruption. The empirical results suggest that online service completion and e-participation are important features of e-government as an anticorruption tool. Evidence suggests that e-participation reduces corrupt legislature activities, public sector theft, executive bribery, and corrupt exchanges. The potential of e-government to deter corruption is higher in countries where corruption is moderate or high and economic development is lower. Higher levels of GDP per capita, foreign direct investment, and political rights are also associated with lower levels of corruption.  相似文献

Portuguese governmental accounting has evolved from essentially a cash‐based budgetary accounting system to an accrual‐based financial and cost accounting system. Evidence from financial reports shows a great level of diversity amongst municipalities' voluntary compliance with the new accounting rules. Using a sample of Portuguese municipalities in the year 2003 we calculate and analyse the levels of compliance with the practices required by law and document the diversity in compliance across municipalities. The differences across municipalities are explained by some fundamental factors: size, financial conditions, urban characteristics, and diffusion across neighbouring municipalities. We show an unexpected effect of size. Larger municipalities comply less with accounting standards. Organizational complexity, conservative practices, and aversion to change may explain this result.

An adaptation of the Cox-Ross/Emanuel-MacBeth call option valuation model for constant elasticity of variance diffusion processes is tested here against an adaptation of the Black-Scholes call option valuation model for the pricing of call currency options. Synchronized transactions data supplied by the Philadelphia Exchange are used. A maximum likelihood estimation procedure indicates a significant association between currency return variances and exchange rate levels. The constant elasticity of variance model exhibits significantly superior pricing accuracy for predictive intervals of three or fewer trading days.  相似文献

The ongoing COVID-19 pandemic has brought terrifying effects for labor markets all around the world. Just as we witness rapid changes in terms of the ways of working (working from home), we are also observing an increase in unemployment. The ways in which major corporations with international operations process their global talent management (GTM) already represents a challenge in relatively stable times and clearly, in a period of such great and sustained turbulence as current experienced, this task becomes still more difficult. Hence, our research aims to study the impact of GTM on the international performance of major companies during the COVID-19 pandemic period. To this end, we surveyed a sample of 59 large companies that act in external markets. Through recourse to multiple linear regressions, we conclude that GTM practices return positive impacts on levels of international performance. Our research returns theoretical implications in terms of the application of integrated GTM models and with the results of significant relevance to corporations operating internationally, and thus enabling them to better understand which strategic human resource management policies will return the best GTM results.  相似文献
