This paper analyzes the important time variation in U.S. aggregate portfolio allocations. To do so, we first use flexible descriptions of preferences and investment opportunities to derive optimal decision rules that nest tactical, myopic, and strategic portfolio allocations. We then compare...

This paper investigates the testable restrictions on the time-series behavior of equity premia implied by a representative agent model whose state- and time-non separable preferences are subject to taste shocks. The model nests state- and time-separable preferences with and without taste shocks...

Résumé : L’hypothèse de déficits jumeaux stipule qu’il existe une relation positive entre les déficits extérieur et budgétaire engendrée suite aux changements de dépenses publiques ou de taxes. La validité de cette hypothèse implique que les problèmes liés aux solvabilités du...

The permanent income hypothesis under certainty equivalence yields a martingale consumption process. Empirically, this hypothesis is rejected because consumption is excessively sensitive to anticipated income. One approach to account for excess sensitivity is to relax certainty equivalence by...

We test whether dynamic, stochastic, general equilibrium artificial economies associated with several labor market institutions provide an adequate characterization of aggregate employment volatility and dynamics. Our test is robust to possible misspecifications about the information set used by...

This paper gauges the relative contribution of risk aversion, inter-temporal substitution and taste shocks on postwar monthly US equity premia. The time-varying consumption, market, and taste risks involved in the Euler equations are recovered from a common factor GARCH process and the MLE are...

Several authors argue that international real business cycle (IRBC) models with incomplete financial markets offer a good explanation of the ranking of cross-country correlations. This conclusion is suspect, because it is based on an analysis of the near steady state dynamics using a linearized...

This paper analyzes the important time variation in US aggregate household portfolios. To do so, we first use flexible descriptions of preferences and investment opportunities to derive household optimal decision rules that nest static, myopic, and non-myopic portfolio allocations. We then...
