This paper tests for the martingale (or random walk) hypothesis in the stock prices of a group of Asian countries. The selected countries represent well-developed markets (Hong Kong and Japan) as well as emerging markets (Korea, Taiwan and Thailand). This paper adopts a new joint variance ratio...

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...

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...

If country and currency risk premiums are positively correlated, a negative international liquidity shock harms twice the economy, thereby substantially increasing interest rates. This harmful positive correlation between country and currency risk premiums observed in some countries is called...

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 tests the random walk hypothesis for the stock markets of the US, Japan, Germany, the UK, Hong Kong and Australia using unit root tests and spectral analysis. The results based upon the augmented Dicky Fuller (1979) and Phillips-Perron (1988) tests and spectral analysis find that...
