Abstract

This paper documents the importance of testing for structural change in the context of emerging markets. Typically, asset pricing factor models for emerging markets are conditioned on world financial market factors such as world equity excess returns, risk and maturity spreads as well as other variables designed to capture world business cycle fluctuations. We show that for many countries, while we cannot reject the model according to one usual chi-square test for overidentifying restrictions, we reject it on the basis of structural change tests, especially when international factors are considered. Much better support and greater stability are found when a local CAPM is tested with size-ranked portfolios. Some evidence of a small-size effect persists for some countries.

Dans cet article, nous montrons l'importance d'utiliser des tests de changement structurel dans le contexte des marchés boursiers en émergence. Les modèles de valorisation das actifs financiers utilisés dans ce contexte sont en général des modèles conditionnels à facteurs fondés sur des facteurs à caractère international tels les rendements excédentaires sur le marché mondial des actions, les écarts de taux captant la prime de risque et la prime de terme, ainsi que d'autres variables visant à mesurer les fluctuations du cycle économique mondial. Nous montrons que dans de nombreux pays, bien que nous ne puissions pas rejeter les modèles en fonction des tests de suridentification habituels de distribution chi-carré, nous les rejetons en fonction des tests de changement structurel, notamment lorsque nous utilisons des factuers internationaux. Nous trouvons des résultats beaucoup plus favorables aux modèles et une plus grande stabilité lorsque nous testons un CAPM local avec des portefeuilles ordonnés selon la taille. Un effet de taille persiste toutefois dans certains pays.
