Edgworth's taxation paradox states that an excise tax can decrease the market price of a good.  This paper presents a new version of the paradox in which a tax reduces price because it attracts entry of additional firms into the market.  The paper also presents two new applications: (i) an...

Carbon leakage is a major concern for policymakers involved with environmental initiatives such as the European Union's emissions trading scheme and similar cap-and-trade proposals in the United States, Australia, and elsewhere.  This paper provides a framework for understanding the drives...

This paper examines the amount of grandfathering needed for an emissions trading scheme (ETS) to have a neutral impact on firm profits. We provide a simple formula to calculate profit-neutral grandfathering in a Cournot model with firms of different sizes and a general demand function. Using...

We consider an observer who makes a finite number of observations of an industry producing a homogeneous good, where each observation consists of the market price and firm specific production quantities.  We develop a revealed preference test (in the form of a linear program) for the hypothesis...

This paper examines the operation of an emissions trading scheme (ETS) in a Cournot oligopoly.  We study the impact of the ETS on industry output, price, costs, emissions, and profits.  In particular, we develop formulae for the number of emissions permits that have to be freely allocated to...
