This paper develops an overlapping generations model of optimal rebalancing where agents differ in age and risk tolerance. Equilibrium rebalancing is driven by a leverage effect that influences levered and unlevered agents in opposite directions, an aggregate risk tolerance effect that depends...

Standard portfolio advice is that agents should hold a constant share of risky assets. All agents cannot, however, follow this advice because supply and demand of risky assets must be equal. To study equilibrium rebalancing, the paper develops an overlapping generations model in which agents...

Using data from the April 2005 Survey of Consumers, we develop an index of investor sophistication from a set of 14 quiz-like questions. We correlate our measure of sophistication with holdings of international investments, measures of diversification, and holdings of an employer's stock. We...
