We analyze optimal policy when consumers of energy-using durables undervalue energy costs relative to their private optima. First, there is an Internality Dividend from Externality Taxes: aside from reducing externalities, they also offset distortions from underinvestment in energy efficiency....

A central justification for social insurance and for other policies aimed at retirement savings is that individuals may fail to make adequate provision during their working years. Much research has focused on myopia and other behavioral limitations. Yet little attention has been devoted to how...

Myopia is increasingly believed to be a significant determinant of behavior and also plays a central role in justifications for social security and policies toward the taxation of capital. It is important, however, to account for labor supply effects, particularly in light of the preexisting...

We describe a regulatory framework that helps consumers who have difficulty sticking to their own long-run plans. Early Decision regulations help long-run preferences prevail by allowing consumers to partially commit to their long-run goals, making it harder for a momentary impulse to reverse...

Many analysts have argued that energy efficiency investments offer an enormous "win-win" opportunity to both reduce negative externalities and save money. This overview paper presents a simple model of investment in energy-using capital stock with two types of market failures: first,...

In a field experiment in Uganda, we find that demand after a free distribution of three health products is lower than after a sale distribution. This contrasts with work on insecticide-treated bed nets, highlighting the importance of product characteristics in determining pricing policy. We put...

This paper incorporates two empirically-grounded insights into a dynamic life cycle portfolio choice model: the fact that investors forego the opportunity to accumulate job-specific skills when they spend time managing their own money, and the observation that efficiency in financial decision...

We document the fact that servicers have been reluctant to renegotiate mortgages since the foreclosure crisis started in 2007, having performed payment reducing modifications on only about 3 percent of seriously delinquent loans. We show that this reluctance does not result from securization:...

In this paper, we examine the effect of observed and unobserved heterogeneity in the desire to die with positive net worth. Using a structural life-cycle model nested in a switching regression with unknown sample separation, we find that roughly three-fourths of the elderly single population has...

We explore household consumption surrounding federal tax returns filings and refunds receipt to test various theories of consumption. Because uncertainty regarding the refund is resolved at filing, precautionary savings theory predicts an increase in consumption at this date. Contrary to this...
