Much of the literature on time inconsistency has studied the external commitment devices that individuals use to address their self-control problems: tying oneself to the mast, staying away from temptation, holding illiquid assets, or "asking controls" from others. This paper, by contrast,...

This paper evaluates the central insight of the Consumption Capital Asset Pricing Model (CCAPM) that an asset’s expected return is determined by its equilibrium risk to consumption. Rather than measure the risk of a portfolio by the contemporaneous covariance of its return and consumption...

This paper analyzes the self-identification process and its role in motivation. We build a model of self-confidence where people have imperfect knowledge about their ability, which in most tasks is a complement to effort in determining performance. Higher self-confidence thus enhances...

I study the welfare cost of business cycles in a complete-markets economy where some people are more risk averse than others. Relatively more risk-averse people buy insurance against aggregate risk, and relatively less risk-averse people sell insurance. These trades reduce the welfare cost of...

While this is typically ignored, the properties of the stochastic process followed by aggregate consumption affect the estimates of the costs of fluctuations. This paper pursues two approaches to modelling aggregate consumption dynamics and to measuring how much society dislikes fluctuations,...

Following the textbook CCAPM, the consumption risk of an asset is typically measured as the contemporaneous covariance of the marginal utility of consumption and the return on that asset. When measured this way, consumption risk is too small to explain the observed equity premium, is negatively...

Under the Economic Growth and Tax Relief Reconciliation Act of 2001, most U.S. taxpayers received a tax rebate between July and September, 2001. The week in which the rebate was mailed was based on the second-to-last digit of the taxpayer's Social Security number, a digit that is effectively...
