Financial liberalisation has offered global investors with new investment opportunities via international portfolio diversification. Proper investment planning as well as portfolio diversification and rebalancing require low correlations between the assets under consideration. In general, correlations between countries have increased during the global financial crisis due to contagion, interdep...

They should reduce their equity position. We study the portfolio problem of a long-horizon investor that allocates between a risk-less and a risky asset in an environment where both volatility and expected returns are time-varying. We find that investors, regardless of their horizon, should substantially decrease risk exposure after an increase in volatility. Ignoring variation in volatility le...

In this paper we show that long run market informational ine¢ ciency and informational cascades can easily happen when trades occur at market clearing prices. We consider a sequential trade model where: (i) the investors’set of actions is discrete; (ii) dealers and investors di¤er in risk aversion; (iii) investors’information is bounded. We show that informational cascade occurs as soon as trad...

This paper addresses how asymmetric information, fads and Lévy jumps in the price of an asset affect the optimal portfolio strategies and maximum expected utilities of two distinct classes of rational investors in a financial market. We obtain the investors’ optimal portfolios and maximum expected logarithmic utilities and show that the optimal portfolio of each investor is more or less than it...

Nonaudit services performed by auditors for their audit clients have long been a focus of concern for regulators. The SEC has mandated disclosure of fees for both audit and nonaudit services in order to provide investors with a more transparent representation of the auditor-client relationship. The purpose of this study is to investigate whether nonaudit service fees influence the value relevan...

We suggest a methodology for the construction of a set of interest rate volatility indices for the Eurozone (EIRVIXs) based on the implied volatility quotes of caps (floors), one of the most liquid interest rate derivatives. These indices reflect the market’s aggregate expectation of volatility of forward rates over both shortand long-term horizons (from one to ten years ahead). Volatility indi...

We show that firms with more short-term institutional investors have better long-term performance in dynamic economic environments. Following exogenous increases in competitive pressure due to large cuts of import tariff rates, firms with more shortterm investors achieve higher growth rates of sales and employees in comparison to other firms in the industries affected by the tariff cuts. To do ...

The disposition effect is the observation that investors hold winning stocks too long and sell losing stocks too early. A standard explanation of the disposition effect refers to prospect theory and in particular to the asymmetric risk aversion according to which investors are risk averse when faced with gains and risk-seeking when faced with losses. We show that for reasonable parameter values...

Volatility is the most widely used measure of risk but its relevance is questionable in many settings. For long-term investors, short-term volatility is a nuisance they just have to live with and disregard as much as possible. Tail risks, however, are critical because, although rare by definition, they have a large impact on terminal wealth. Using a comprehensive sample that spans over 19 count...
