This paper analyzes the impact of consumption externalities on the ``Pigouvian ranking,'' according to which the second-best level of public good provision is \emph{smaller} than the first-best level. Consumption externalities introduce exceptions to the Pigouvian ranking. Two necessary and...

This work examines the influence of Coasian thought on the analysis of externalities as used by economists and legal economists. Ronald Coase, a Chicago scholar, advanced a series of critiques of the Pigovian tax system; the theorem that bears his name is merely the best known. In his 1960 work,...

This article critically evaluates the current state of research on education externalities. It occurs that much of the confusion regarding their magnitude results from conceptual misunderstandings pertaining to their nature. The essay distinguishes the concepts education, teaching, and...

The impact of the investment in absorptive capacity on transboundary pollution is studied by considering two countries each of them regulating a firm. Firms can invest in original research and in absorptive research to lower their pollution intensity. The absorptive research enables a firm to...

We consider in this paper a duopoly competing in quantities and where�firms can invest in R&D to control their emissions. We distinguish between effort carried out to acquire first-hand knowledge (original R&D)and effort to develop an absorptive capacity to be able to capture part of the...

This paper demonstrates that a pollution tax with a fixed cost component may lead, by itself, to segregation between clean and dirty firms without heterogeneous preferences or increasing returns. We construct a simple model with two locations and two industries (clean and dirty) where pollution...

The Australian Government has produced a CO2-equivalent tax proposal with a difference, it is a short prelude to an emission trading scheme that will allow the increasing rate of emissions to continue, while being a net cost to the Treasury. That cost extends to allowing major emitters to make...

Optimal tax theory has difficulty rationalizing high marginal tax rates at the upper end of the income distribution. In this paper, I construct a model of optimal income taxation in which agents' preferences are interdependent. I derive a simple expression for optimal taxes that accommodates...

Many countries are implementing or at least considering policies to counter increasingly certain negative impacts from climate change. An increasing amount of research has been devoted to the analysis of the costs of climate change and its mitigation, as well as to the design of policies, such...

Most studies of the optimal provision of public goods or the excess burden from taxation assume that individual utility is independent of other individuals' consumption. This paper investigates public good provision and excess burden in a model that allows for interdependence in consumption in...
