We consider the classical Merton problem of lifetime consumption-portfolio optimization problem with small proportional transaction costs. The first order term in the asymptotic expansion is explicitly calculated through a singular ergodic control problem which can be solved in closed form in...

In a simple single commodity certainty setting with changing tastes, a consumer's consumption plan can be obtained using naive or sophisticated choice. Although in general these solutions diverge, they agree in the special case where the changing tastes are represented by discounted logarithmic...

This paper provides a formal justification for the existence of subjective random components intrinsic to the outcome evaluation process of decision makers and explicitly assumed in the stochastic choice literature. We introduce the concepts of admissible error function and generalized certainty...

We present a survey design that generalizes static conjoint experiments to elicit inter-temporal adoption decisions for durable goods. We show that consumers' utility and discount functions in a dynamic discrete choice model are jointly identified using data generated by this specific design. In...

This paper develops a ldquo;consensus votingrdquo; model for estimating preferences of judges on federal circuit courts. Rather than assuming sincere voting, as is typical in ideal point estimation, this model accounts for the norm of consensus in the courts of appeals by including a ldquo;cost...

This paper introduces the concept of ordient for binary relations (prefer-ences), a relative of the concept of gradient for functions (utilities). The mainmotivation for this study is to replace the binary relation at the center stageof economic analysis, rather than its representation (whenever...

We apply the aggregation property of Identical Shape Harmonic Absolute Risk Aversion (ISHARA) utility functions to analyze the comparative statics properties of a bargaining model with uncertainty. We identify sufficient and necessary conditions under which an increase in one's degree of risk...

We present sufficient conditions for monotone matching in environments where utility is not fully transferable between partners. These conditions involve not only complementarity in types of the total payoff to a match, as in the transferable utility case, but also monotonicity in type of the...
