In this paper we show that flexible probability distribution functions, in addition to being able to capture stylized facts of financial returns, can be used to identify pure higher-order effects of investors' optimizing behavior. We employ the five-parameter weighted generalized beta of the second kind distribution—and other density functions nested within it—to determine the conditions under which risk averse, prudent and temperate agents are diversifiers in the standard portfolio choice theory. Within this framework, we illustrate through comparative statics the economic significance of higher-order moments in return distributions. 相似文献

A unit volume zero-intelligence (ZI) model is defined and the distribution of its L1 process is recursively described. Further, a generalized ZI model allowing non-unit market orders, shifts of quotes and general in-spread events is proposed and a formula for the conditional distribution of its quotes is given, together with a formula for price impact. For both the models, MLE estimators are formulated and shown to be consistent and asymptotically normal. Consequently, the estimators are applied to data of six US stocks from nine electronic markets. It is found that more complex variants of the models, despite being significant, do not give considerably better predictions than their simple versions with constant intensities. 相似文献

We examine whether performance persistence is suspicious. Top quintile portfolios formed on the Sharpe ratio, alpha, and information ratio persistently outperform similarly constructed mediocre third quintile portfolios throughout our sample period, but performance is more modest and less persistent when portfolios are formed on the excess manipulation‐proof performance measure (EMPPM). By selecting funds formed on ranking by Sharpe and information ratios, investors also select funds that have persistently doubtful performance according to the doubt ratio. In contrast, portfolios formed on alphas and especially the EMPPM have much less excess and persistent doubt. 相似文献

Information transparency is a relevant factor nowadays. The current legislation has forced hazardous companies to improve their communication policy with the local community, but this entails the difficulty that each individual has a different need for information. This study considers the main antecedents of need for information to explain these differences. The paper analyses, to our knowledge for the first time, the direct influence of personal beliefs about environmental issues on the individual’s need for information. The research focused on the residents (992) of an area near to a petrochemical complex. The results, derived from the structural equation modelling analysis, confirmed the influence of environmental beliefs, trust in companies and negative affective response on the need for information. In the light of these results, we recommend that the companies of the complex develop a risk communication policy based on personal environmental beliefs, in order to understand the public’s concerns and their needs for risk information. Finally, the analysed companies need to see risk communication as a long-term and ongoing process that involves active dialogue and enables stakeholders’ participation, with the aim of establishing a communication network. 相似文献

We assemble a novel data set of industry panel data for the corporate sector and the entire economy across a number of countries to explore the connection between investment and stock prices. The link is present in all samples, in both the aggregate and industry dimensions, and increases with stock market development. Fundamentals are less related to prices in underdeveloped markets but are similarly related to investment everywhere. Thus, the active informant interpretation does not seem to be the main force behind the stock market–investment relationship. In addition, industries that are more dependent on equity finance, and where investors are strongest, exhibit higher sensitivity to prices, especially in developed markets. 相似文献

The aim of this paper is to examine which of the assets commonly believed to be safe havens do, in fact, protect investors during periods of severe financial instability. Using a broad dataset of 32 assets over the period of 1964–2014, we examine the relationship of these assets with the US equity market during financial crises to determine which of them are safe havens for US investors, hedges, or speculations. We find that the US Treasuries and Japanese yen are the strongest safe haven investments in months characterized by large declines in market value or excessive volatility. We also document that the recent global financial crisis had significantly negative ramifications on the safe haven properties of many of these assets. Our out-of-sample analyses show that while, in general, predictive market exposures are negatively correlated with asset returns in strong market downturns, those of even the strongest safe haven assets are often statistically insignificant. 相似文献

This cross-cultural study empirically investigates the cultural determinants of macro-level social and commercial entrepreneurship from a new institutional theory perspective. This study investigates if cultural shifts in cultural values, operationalized through the World Values Survey (WVS), impact the prevalence rates of social and commercial entrepreneurship at the national level. Social and commercial entrepreneurship rates are drawn from the 2009 Global Entrepreneurship Monitor (GEM) and aggregated for 53 countries in this cross-sectional analysis using multivariate regression. Findings indicate that traditional societal values positively impact commercial entrepreneurship prevalence rates, but negatively impact social entrepreneurship rates. Furthermore, self-expression societal values positively impact social entrepreneurship prevalence rates. 相似文献
