Information frictions imply it is reasonable to expect the same commodity, in a given location, to sell for different prices at the same time. Aguiar and Hurst (AH) [2007] demonstrate how the search behavior implied by these price differences can be used estimate the opportunity cost of time....

Most economic models for time allocation ignore constraints on what people can actually do with their time. Economists recently have emphasized the importance of considering prior consumption commitments that constrain behavior. This research develops a new model for time valuation that uses...

With the American Time Use Survey of 2003 and 2004 we first examine whether additional market work has neutral impacts on the mix of non-market activities. The estimates indicate that fixed time costs of market work alter patterns of non-market activities, reducing leisure time and mostly...

Why do individuals volunteer their time even when recipients receive far less value than the donor's opportunity cost? Previous models of altruism that focus on the overall impact of a gift cannot rationalize this behavior, despite its prevalence. We develop a model that relaxes this assumption,...

This paper addresses the issue of the optimal stock of international reserves in terms of a statistical model in which reserves affect both the probability of a Sudden Stop-as well as associated output costs-by reducing the balance-sheet effects of liability dollarization. Optimal reserves are...

The flow opportunity cost of moving from unemployment to employment consists of foregone public benefits and the foregone value of non-working time in units of consumption. We construct a time series of the opportunity cost of employment using detailed microdata and administrative or national...

Medical care at the end of life, which is often is estimated to contribute up to a quarter of US health care spending, often encounters skepticism from payers and policy makers who question its high cost and often minimal health benefits. It seems generally agreed upon that medical resources are...

This paper measures the risk-adjusted performance of US buyouts. It draws on a unique and proprietary set of data on 133 US buyouts between 1984 and 2004. For each of them we determine a public market equivalent that matches it with respect to its timing and its systematic risk. After a...
