The structure of many models in economics and finance depends on majorization properties of convolutions of distributions. In this paper, we analyze robustness of these properties and the models based on them to heavy-tailedness assumptions. We show, in particular, that majorization properties...

We propose a semi-parametric approach to investigate whether co-dependence across markets increase in periods of extreme returns. Given that returns on one market fall in the extreme tail of their own distribution, we compute the conditional probability that returns on another market will also...

This paper introduces a nonparametric estimator for tail dependence in the constant conditional correlation GARCH framework, in contrast to existing estimators that impose the iid assumption. So long as stationarity is satisfied, the difference between the distribution of the tail dependence...

This paper investigates the uncertainty in variance and covariance of asset returns. It is commonly believed that these second moments can be estimated very accurately. However, time varying volatility and nonnormality of asset returns can lead to imprecise variance estimates. Using CRSP value...

We examine the equity market price interdependence between Australia, on one hand, and Japan, US, UK, Hong Kong, Singapore, Taiwan and Korea, on the other hand, based on Hacker and Hatemi-J (2003) bootstrap causality tests with leveraged adjustments. We cover the period January 1, 1993 to...

Surveys of Australian superannuation funds verify that most international bond holdings, but not equity holdings, are hedged for currency risk. We compare the mean-variance efficiency of this practice with two alternative strategies: a conventional forward hedge; and a selective hedge triggered...

Myopic loss aversion has been used to explain why a high equity premium might be consistent with plausible levels of risk aversion. The intuition is that it plays the role of high risk aversion in portfolio choice. But if so, should these agents not perceive larger gains from international...

This paper proposes a model encompassing alternative views of contagion by highlighting the different channels of transmission of financial crises in an unifying framework. We study investor behaviour when they are affected by external habit formation. It is shown how international portfolio...

We show that a model of the spirit of capitalism can generate a high degree of international risk sharing as measured by the discount-factor-based approach of Brandt, Cochrane, and Santa-Clara (2001), even when consumption and portfolio holdings exhibit "home bias". We also show how portfolio...
