Movements in asset prices are a major risk confronting individuals. This paper establishes new asset pricing results when agents differ in risk preference, time preference and/or expectations. It shows that risk tolerance is a critical concept driving savings decisions, consumption allocations,...

A powerful isomorphism allows differences in time preference and expectations to be swept away in the analysis, yielding an equivalent economy whose agents differ merely in risk aversion. These results hold great potential to simplify the analysis of heterogeneous-agent economies, as we...

Differences in ethical behavior between members of the upper and lower classes have been at the center of civic debates in recent years. This paper presents a framework for understanding how class affects ethical standards and behaviors. The framework is applied using data from a large Dutch...
