Information asymmetry is a necessary prerequisite for testing adverse selection.This paper applies this sequence of tests to Mauritian slave auctions. Dynamicauction theory with private value highlights more aggressive bidding by uninformedbidders and higher prices when an informed participant...

Richer and healthier agents tend to hold riskier portfolios and spend proportionallyless on health expenditures. Potential explanations include health and wealth eects onpreferences, expected longevity or disposable total wealth. Using HRS data, we perform astructural estimation of a dynamic...

Reference–dependent preference models assume that agents derive utility fromdeviations of consumption from benchmark levels, rather than from consumptionlevels. These references can be either backward-looking (as explicit in the Habit literature) or forward-looking (as implicitly suggested by...

This paper proposes a new wealth-dependent utility function for the inter-temporal consumption and portfolio problem, in which the subsistance (bliss) con-sumption level is a function of wealth. Ratchet effects obtain when higher wealth in-creases the subsistance consumption level; blas´...

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...

The empirical literature on the asset allocation and medical expenditures ofU.S. households consistently shows that risky portfolio shares are increasing inboth wealth and health whereas health investment shares are decreasing in thesesame variables. Despite this evidence, most of the existing...
