Campbell and Cochrane (1999) formulate a model that successfully explains a wide variety of asset pricing puzzles, by augmenting the standard power utility function with a time-varying subsistence level, or "external habit", that adapts nonlinearly to current and past average consumption in the...

This paper introduces a tractable, structural model of subjective beliefs. Forward-looking agents care about expected future utility flows, and hence have higher current felicity if they believe that better outcomes are more likely. On the other hand, biased expectations lead to poorer decisions...

We present a theory of choice among lotteries in which the decision maker's attention is drawn to (precisely defined) salient payoffs. This leads the decision maker to a context-dependent representation of lotteries in which true probabilities are replaced by decision weights distorted in favor...

Even if an asset has no fundamental uncertainty with a constant dividend process, a stochastic sentiment-driven equilibrium for the asset price exists besides the well-known fundamental equilibrium. Our paper constructs such sentiment-driven equilibria under general utility functions within an...

We provide a user's guide to exotic' preferences: nonlinear time aggregators, departures from expected utility, preferences over time with known and unknown probabilities, risk-sensitive and robust control, hyperbolic' discounting, and preferences over sets ( temptations'). We apply each to a...

Risk and time are intertwined. The present is known while the future is inherently risky. Discounted expected utility provides a simple, coherent structure for analyzing decisions in intertemporal, uncertain environments. However, we document robust violations of discounted expected utility,...

This paper revisits the Home Bias Puzzle -- the relatively low interna- tional diversification of portfolios. We suggest that part of the diversifi- cation puzzle may be due to reliance on the conventional CAPM model as the benchmark predicting patterns of diversification. We compare the asset...

We study identification of time inconsistency when an agent at time 0 makes an advance commitment, and later at time 1 can revise their choice after possibly receiving additional information. Roughly speaking, we prove that the only data that reject time-consistent expected utility maximization...

Many economic decisions involve a binary choice - for example, when consumers decide to purchase a good or when firms decide to enter a new market. In such settings, agents' choices often depend on imperfect expectations of the future payoffs from their decision (expectational error) as well as...

Economists have been reluctant to rely on culture as a possible determinant of economic phenomena. The notion of culture is so broad and the channels through which it can enter the economic discourse so vague that it is difficult to design testable hypotheses. In this paper we show this does...
