This paper derives intuitive and empirically useful formulas for the optimal pricing of passenger transit and for the welfare effects of adjusting current fare subsidies, for peak and off-peak urban rail and bus systems. The formulas are implemented based on a detailed estimation of parameter...

We review the burgeoning literature on the employment effects of minimum wages—in the United States and other countries—that was spurred by the "new minimum wage research" beginning in the early 1990's. The wide range of existing estimates makes it difficult for us to draw broad...

We consider a policymaker who must choose between the status quo and proposals made by lobbyists. Each lobbyist aims to maximize the tariff accorded his industry, but realizes that if he proposes too high a tariff, the policymaker may choose the proposal offered by another lobbyist which...

The U.S. Patent and Trademark Office resolves patent priority disputes in patent interference cases. Using a random sample of cases declared between 1988 and 1994, we establish a connection between patent interferences and patent races, and then use the data to consider some key issues in...

How strong is the interdependence between the macroeconomy and the stock market? This paper estimates a New Keynesian general equilibrium model, which includes a wealth effect from asset price fluctuations to consumption, to assess the quantitative importance of interactions among the stock...

The recent literature on congestion pricing with large agents contains a remarkable inconsistency: though agents are large enough to recognize self-imposed congestion and exert market power over prices, they do not take into account the impact of their own actions on the magnitude of congestion...

Housing rents may be influenced by characteristics of nearby properties, an effect captured by spatial autoregression in a hedonic rent equation. We investigate the implications of spatial autoregression for measuring the marginal welfare effects due to a change in a residential amenity such as...

What generates persistence in inflation? Is inflation persistence structural? This paper investigates learning as a potential source of persistence in inflation. The paper focuses on the price-setting problem of firms and presents a model that nests structural sources of persistence (indexation)...

This paper develops a theory of consumer boycotts. Some consumers care not only about the products they buy but also about whether the firm behaves ethically. Other consumers do not care about the behavior of the firm but yet may like to give the impression of being ethical consumers....
