Fiscal policy in the U.S. and other countries renders intertemporal budgets non-differentiable, nonconvex, and discontinuous. Consequently, assessing work and saving responses to policy requires global optimization. This paper develops the Global Life-Cycle Optimizer (GLO), a stochastic...

In 1992, the United States Centers for Medicare and Medicaid Services (CMS) introduced new insurance coverage for two preventive services influenza vaccinations and mammograms. Economists typically assume transactions occur with perfect information and foresight. As a test of the value of...

Imperfect information and inattention to energy costs are important potential justifications for energy efficiency standards and subsidies. We evaluate these policies in the lightbulb market using a theoretical model and two randomized experiments. We derive welfare effects as functions of...

Consumer search is not only costly but also tiring. We characterize the intertemporal effects that search fatigue has on oligopoly prices, product proliferation, and the provision of consumer assistance (i.e., advice). These effects vary based on whether search is all-or-nothing or sequential in...

This paper investigates how concern for the environment translates into predictable patterns of consumer behavior. Two types of behavior are considered. First, individuals who care about environmental quality may voluntarily restrain their consumption of goods and services that generate a...

In the absence of a national carbon tax, household driving and electricity consumption impose social costs. Suburbanites drive more and consume more electricity than center city residents. If more suburbanites purchase electric vehicles (EV) and install solar panels, then their greenhouse gas...

We estimate the degree of 'stickiness' in aggregate consumption growth (sometimes interpreted as reflecting consumption habits) for thirteen advanced economies. We find that, after controlling for measurement error, consumption growth has a high degree of autocorrelation, with a stickiness...
