報告	Clifford Winston (The Brookings Institution) Competition and Welfare in the US Airline Industry
Abstract	We develop a structural econometric model of competition in U.S. domestic airline markets to assess how traveler welfare may be　affected by the exit of an industry competitor. We find that Southwest provides the greatest welfare to travelers while other low-cost carriers also contribute significant benefits to the flying public. Of the legacy carriers, only United and Delta substantially raise traveler welfare while American, US Airways, and Continental actually reduce traveler welfare. We conclude that the market is efficiently determining which airlines remain in the industry and that financial assistance to carriers that may otherwise be liquidated is unwarranted.

報告	John Weymark (Vanderbilt University) Public Good Provision and the Comparative Statics of Optimal Nonlinear Income Taxation (with Craig Brett) [PDF]
Abstract	Comparative static properties of the solution to an optimal nonlinear income tax problem are provided for a model in which the government both designs an income tax schedule for redistributive purposes and provides a public good optimally. There are two types of individuals, distinguished by their skill levels, who have the same quasilinear preferences for labour supply and the consumption of a private and a public good. The parameters for which comparative statics are obtained are the weights in a weighted utilitarian social welfare function, the prices of the private and public goods, a taste parameter that measures the onerousness of working, and the individual skill levels.

Airplanes and Comparative Advantage

Abstract: Airplanes are a fast but expensive means of shipping goods. This fact has implications for comparative advantage. The model of the paper shows that countries that are far from their export markets will specialize in high value/weight products, which will be shipped on airplanes. Less remote exporters will specialize in low value/weight products which will be sent by ship, train, or truck. These implications are confirmed using detailed data on U.S. imports from 1990 to 2003. Distance from the US and air shipment are associated with much higher import unit values.

Parry) Abstract: This paper derives formulas for optimal peak and off-peak urban rail and bus fares, and applies them to Washington DC, Los Angeles and London. The model accounts for congestion, pollution, and accident externalities on all modes; scale economies in transit supply; costs of accessing and waiting for transit service as well as service crowding costs; pre-existing fuel taxes; and agency adjustment of transit frequency, vehicle size, and route network to changes in demand for passenger miles. We find that optimal fare subsidies can be quite substantial, but their major determinants differ greatly according to time period, mode, adjustment of service frequency, and city.
