The goal of this paper is to bring some unity to the theoretical side of the debate on internalization of airport congestion by showing that all the literature's theoretical results can be derived within one simple and unified framework. The analysis starts by replicating the results of...

We show that, even with flexible domestic wages, international outsourcing may worsen the welfare of the home country and reduce the profits of all firms. If wages are rigid, outsourcing is welfare-improving if and only if the sum of the "trade creation" effect and the "exploitation effect"...

We propose an overlapping generations economy where households care about relative consumption, the difference between their consumption and the consumption of their reference group. An individual's consumption is driven by the comparison of his lifetime income and the lifetime income of his...

A finite number of sellers (n) compete in schedules to supply an elastic demand. The costs of the sellers have uncertain common and private value components and there is no exogenous noise in the system. A Bayesian supply function equilibrium is characterized; the equilibrium is privately...

The Green Paradox states that, in the absence of a tax on CO2 emissions, subsidizing a renewable backstop such as solar or wind energy brings forward the date at which fossil fuels become exhausted and consequently global warming is aggravated. We shed light on this issue by solving a model of...

We consider a dynamic auction problem motivated by the traditional single-leg, multi-period revenue management problem. A seller with C units to sell faces potential buyers with unit demand who arrive and depart over the course of T time periods. The time at which a buyer arrives, her value for...

We consider an environment where potential buyers of an indivisible good have liquidity constraints, in that they cannot pay more than their `budget' regardless of their valuation. A buyer's valuation for the good as well as her budget are her private information. We derive constrained-e±cient...

This paper builds a macroeconomic model of equilibrium unemployment in which firms persistently face difficulties in selling their production and this affects their decisions to create jobs. Due to search-frictions on the product market, equilibrium unemployment is a U-shaped function of the...

This paper characterizes the optimal redistributive taxation when individuals are heterogeneous in two exogenous dimensions: their skills and their values of non-market activities. Search-matching frictions on the labor markets create unemployment. Wages, labor demand and participation are...
