Multi-Regime Common Cyclical Features
In this paper we consider the hypothesis that particular short-run co-movements indicationg that shocks have similar responses might only exist for a particular regime and not for the whole sample. A two-step procedure is set up to test and estimate the multi-regime common cyclical feature. This approach is illustrated by analyzing the stability of the McCallum''s (1994) monetary policy reaction function for Danish data.Economics ;
Liberalization and Stock Market Co-Movement between Emerging Economies
In this paper, we investigate the impact of trade and financial liberalization on the degree of stock market co-movement among emerging economies. Using a sample of 25 developing countries observed over 15 years, we estimate the impact of reforms which aim at opening these countries to trade and financial channels to the rest of the world. The estimation of time-varying cross-country correlations allows the econometric investigation to be performed using a panel data framework, raising hence the quality of the statistical inference. Our results offer strong support in favor of a positive impact of trade and financial liberalization reforms on the degree of cross-country stock market linkages.stock market synchronization, financial integration, trade integration, emerging markets
Testing for Asset Market Linkages: A new Approach based on Time-Varying Copulas
This paper proposes a new approach based on time-varying copulas to test for the presence of increases in stock market interdependence after financial crises, also known as shift-contagion process. We show that the previous approaches that take into account changes in volatility regimes are biased when the DGP is either copula based or when there is a break in variance significantly different from the one in correlation. A sequential algorithm is then elaborated to remove this bias. Applied to the recent 1997 Asian crisis, it confirms that breaks in variances always precede those in conditional correlation. It also turns out that this financial turmoil has been characterized by shift-contagion.financial economics and financial management ;
Evidences of Interdependence and Contagion using a Frequency Domain Framework
The purpose of this paper is to propose a new measure of contagion. Our approach to testing contagion is based on the frequency analysis of causality developed recently by Breitung and Candelon (2004). This approach handles, in a unified framework, several of the statistical problems identified in the literature. It also permits clear differentiation between temporary and permanent shifts in cross-market linkages: the first case is contagion while the second one is simply a measure of interdependence among markets. In examining the âTequilaâ and Asian crises, we find evidence for contagion during both. It also turns out that during the Asian crisis both contagion and higher interdependence have contributed simultaneously to the diffusion of the crisis in Asia. The spillover effects of these crises have been geographically limited to the region where the shock originated.macroeconomics ;
