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...

This paper analyzes a dynamic stochastic equilibrium model of an asset market based on behavioral and evolutionary principles. The core of the model is a non-traditional game-theoretic framework combining elements of stochastic dynamic games and evolutionary game theory. Its key characteristic...

Historically, the literature on money management has not consistently applied the rational expectations equilibrium concept. We explain why and summarize developments in the money management literature that do apply this concept correctly. We demonstrate that the rational expectations...

Portfolio constraints often prevent financial derivatives from being synthetically created by primitive assets and thus, open a way for the 'redundant' assets to participate in expanding risk-sharing opportunities. They bring about peculiar portfolios, called 'link portfolios,' at an aggregate...

This article studies optimal, dynamic portfolio and wealth/consumption policies of expected utility maximizing investors who must also manage market-risk exposure which is measured by Expected Shortfall (ES). We find that ES managers can incur larger losses when losses occur, compared to both...

We study a dynamic mean-variance portfolio optimization problem under the reinforcement learning framework, where an entropy regularizer is introduced to induce exploration. Due to the time-inconsistency involved in a mean-variance criterion, we aim to learn an equilibrium strategy. Under an...

Forecasting exchange rates remains a tricky issue for economists. In spite of a theoretical consistent framework, macroeconomic models fail to beat random walk models and market expectations doesn't have any predictive power. This article addresses some problems of exchange rate macroeconomic...

It is commonplace to link neoclassical economics to 18th- or 19th-century physics and its notion of equilibrium, of a pendulum once disturbed eventually coming to rest. Likewise, an economy subjected to an exogenous shock seeks equilibrium through the stabilizing market forces unleashed by the...
