When all financial assets have risky returns, the mean-variance portfolio model is potentially subject to two types of bliss points. One bliss point arises when a von Neumann-Morgenstern utility function displays negative marginal utility for sufficiently large end-of-period wealth, such as in...

We calculate the socially optimal level of illiquidity in an economy populated by households with taste shocks and present bias (Amador, Werning, and Angeletos 2006). The government chooses mandatory contributions to respective spending/savings accounts, each with a different pre-retirement...

This paper analyzes optimal portfolio choice and consumption with stochastic volatility in incomplete markets. Using the Duffie-Epstein (1992) formulation of recursive utility in continuous time, it shows that the optimal portfolio demand for stocks under stochastic volatility varies strongly...

This paper argues that the relation between temptations and the level of consumption plays a key role in explaining the observed behaviors of the poor. Temptation goods are defined to be the set of goods that generate positive utility for the self that consumes them, but not for any previous...

We propose a model where voters experience an emotional cost when they observe a firm that has displayed insufficient concern for other people's welfare (altruism) in the process of making high profits. Even with few truly altruistic firms, an equilibrium may emerge where all firms pretend to be...

This paper starts by discussing consumers' cognitive and emotional reaction to posted prices. Cognitively, some consumers do not appear to make effective use of price information to maximize their consumption-based utility. Emotionally, prices can induce regret and anger among consumers. The...

Why do inefficient -- non-growth enhancing -- institutions emerge and persist? This paper develops a simple framework to provide some answers to this question. Political institutions determine the allocation of political power, and economic institutions determine the framework for policy-making...

Recent policy proposals have suggested taxing top incomes at very high rates on the grounds that some or all of the highest wage earners are engaged in socially unproductive or counterproductive activities, such as externality imposing speculation in the financial sector. To address this, we...

We examine misconduct in credence good markets with price taking experts. We propose a market-level model in which price-taking experts extract surplus based on the value of their firm's brand and their own skill. We test the predictions of the model using sales complaint data for exclusive and...
