In this paper we develop a simple procedure which delivers tests for the pres-ence of a broken trend in a univariate time series which do not require knowledgeof the form of serial correlation in the data and are robust as to whether theshocks are generated by an I(0) or an I(1) process. Two...

This paper compares emissions trading based on a cap on total emissions (permit trading)and on relative standards per unit of output (credit trading). Two types of market structureare considered: perfect competition and Cournot oligopoly. The effect of combining the twoschemes is also...

We suggest an alternative way of analyzing the canonical Bergstrom-Blume-Varian model of non-cooperative voluntary contributions to a public goodthat avoids the proliferation of dimensions as the number of players is in-creased. We exploit this approach to analyze models in which the...

We present a rigorous, yet elementary, demonstration of the existence of a uniqueLindahl equilibrium under the assumptions that characterize the standard n-player public goodmodel. Indeed, our approach, which exploits the aggregative structure of the public goodmodel, lends itself to a...

Fundamentals may determine the range of real exchange rate fluctuation, through signalsof misalignment, even if they are not a major influence on the level within that range.This can explain the puzzle that more open economies experience lower real exchangerate volatility...
