This paper characterizes the forces that determine time-variation in expected international asset returns. We offer a number of innovations. By using the latent factor technique, we do not have to prespecify the sources of risk. We solve for the latent premiums and characterize their...

[fre] Depuis les travaux de Cournot sur le duopole en 1838, la théorie de l'oligopole n'a progressé que lentement, ouvrant parfois la voie à l'étude d'autres formes de marché telles que celle de la concurrence monopolistique.. Il a semblé intéressant de déterminer les entreprises qui...

We propose a simple metric to measure two aspects of market integration, namely economic integration (defined as a common cash flow dynamic) and financial integration (defined as a common risk pricing dynamic) and then examine their evolution through time while controlling for volatility. We...

We study whether relative optimism leads to home bias in portfolio holdings by looking at two novel databases: a survey that includes expectations of identified professional asset management companies for equity, bonds and currencies, and the IMF portfolio holdings data for equity and bonds. We...

We develop a global equilibrium asset pricing model assuming that investors suffer from foreign aversion, a preference for home assets based on familiarity. Using a utility formulation inspired by regret theory, we derive closed-form solutions. When the degree of foreign aversion is high in a...

We propose a novel regime-switching model to study correlation asymmetries in international equity markets. We decompose returns into frequent-but-small diffusion and infrequent-but-large jumps, and derive an estimation method for many countries. We find that correlations due to jumps, not...

Global asset allocation provides risk diversification. But international market correlation increases sharply during global crises and diversification benefit disappears when it is most needed. We model these correlation breaks and derive the asset allocation implications. The model can quickly...
