This paper analyzes the link between herd behavior and asset prices in a multi-good pure-exchange economy where investors' preferences evolve over time in response to the consumption decisions of other investors. More precisely, the rule of updating preferences incorporates a bandwagon effect,...

This paper proposes a pure-exchange economy with three key ingredients: habit formation, stochastic moments of aggregate consumption, and a small degree of heterogeneity in risk aversion consistent with empirical data. We obtain closed formulas for many equilibrium quantities, including the...

In 1995, Benartzi and Thaler introduced the concept myopic loss aversion to explain the equity premium puzzle. They provided empirical evidence to support their arguments. Recently, Durand, et al. criticized this empirical analysis. They propose an approach which not only rejects the...

The longest bull market in US stock market history is over. Uncertainty over the public health and economic impact of the coronavirus pandemic will keep markets extremely volatile, making it likely we'll touch a wide range of price levels in the months ahead. Amidst such uncertainty, it's a...

This study brings to light the new empirical fact that flows into US domestic equity mutual funds depend less on past fund returns when the risk-free rate declines. A one-percent drop in interest rates is associated with a decrease in the slope of the flow-performance relationship of around 10%....

This study examines risk premia in a laboratory market featuring a long-lived asset. The research is enabled by prevention of the persistent bubbles and crashes endemic to laboratory markets utilizing long-lived assets. Positive, statistically significant risk premia are reported, in support of...

These days it's become convention (reinforced by the media's treatment of wealth) to assess our net worth by tallying up the market value of our financial assets, even though it's more natural and useful to think of our wealth as a stream of dollars over time given the nature of our income and...

A representative consumer uses Bayes' law to learn about parameters of several models and to construct probabilities with which to perform ongoing model averaging. The arrival of signals induces the consumer to alter his posterior distribution over models and parameters. The consumer's...

When investors have incomplete information, expected returns, as measured by an econometrician, deviate from those predicted by standard asset pricing models by including a term that is the product of the stock's idiosyncratic volatility and the investors' aggregated forecast errors. If...

We incorporate joint learning about state and parameter into a consumption-based asset pricing model with rare disasters. Agents are uncertain whether a negative shock signals the onset of a disaster or how much long-term damage a disaster will cause and they update their beliefs over time. The...
