Micro–macro models associate the coarse-grained molecular scale of the kinetic theory to the macroscopic scale of continuum mechanics. The conservation equations are solved along with the microscopic equation or the so-called Fokker–Planck equation. In this paper, a micro–macro approach...

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 as...

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...

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...
