Economic evaluation of green or renewable power should compare the cost of renewable power with the cost savings from displaced fossil generation plus the avoided harm from reduced emissions of air pollution and greenhouse gases. We use existing estimates of the values of the harm and we...

We study mechanism design in a setting where agents know their types but are uncertain about the utility from any alternative. The final realized utility of each agent is observed by the principal and can be contracted upon. In such environments, the principal is not restricted to using only...

We develop a financial market trading model in the tradition of Glosten and Milgrom (1985) that allows us to incorporate non-trivial volume. We observe that in this model price volatility is positively related to the trading volume and to the absolute value of the net order flow, i.e. the order...

Existing economic theories of the family suggest that public transfer programs in which funds are targeted to women, by improving women’s bargaining position in the household, may decrease the incidence of spousal abuse. We study this prediction empirically using data from a unique survey in...

Investors frequently hold equity in tax-exempt savings vehicles such as pension plans, despite the prediction of the standard model that they hold only bonds. We provide a new explanation for this empirical puzzle based on differences between pensions and taxable assets in the tax treatment of...

We develop an endogenous growth model in which new technology and new skills are bounded complements they complement each other up to a point, but beyond this the impact of each factor is constrained by the level of the other. As a result, both technological progress and human capital...

This paper considers the design of individual quota programs for fisheries where more than one market class of fish is harvested and where a manager is uncertain about the fishing technology, prices, stock levels, and compliance. In particular, the paper considers three problems that follow from...

We derive necessary and sufficient conditions on preferences for uniform taxation to be Pareto efficient in a many-consumer economy. We argue that uniformity is desirable only under conditions far more restrictive than suggested in previous literature, most of which is based on analysis of a...

The incremental innovations that underly much of modern economic growth typically involve changes to one or more components of a complex product. This creates a tension. On the one hand, a principal would like an agent to contribute innovative components. On the other hand, ironing out...
