Perspectives on Productivity and Potential Output Growth: A Summary of the Joint Banque de France/Bank of Canada Workshop, 24-25 April 2006

A nation's productivity is the prime determinant of its real incomes and standard of living, as well as being a major determinant of its potential output. In the short run, deviations of actual output from potential output are a useful indicator of inflationary pressures. This article is a short summary of the proceedings of the workshop, which focus on productivity and potential output growth among industrialized countries. The research is organized under three main themes: estimating potential growth; productivity and growth; and institutions, policies, and growth.

Environmental Controls, Scarcity Rents, and Pre-Existing Distortions

Debate about the Double Dividend Hypothesis has focused on whether an environmental policy raises revenue that can be used to cut other distorting taxes. In this paper, we show that this focus is misplaced. We derive welfare results for alternative policies in a series of analytical general equilibrium models with clean and dirty goods that might be produced using emissions as well as other resources, in the presence of other pre-existing distortions such as labor taxes or even monopoly pricing. We show that the same welfare effects of environmental protection can be achieved, without exacerbating the labor distortion, by taxes that raise revenue, certain command and control regulations that raise no revenue, and even subsidies that cost revenue. Instead, the pre-existing labor tax distortion is exacerbated by policies that generate privately-retained scarcity rents. These rents raise the cost of production, raise equilibrium output prices, and thus reduce the real net wage. Such policies include both quantity-restricting command and control policies and certain marketable permit policies.

Tax Incidence

This chapter reviews the concepts, methods, and results of studies that analyze the incidence of taxes. The purpose of such studies is to determine how the burden of a particular tax is allocated among consumers through higher product prices, workers through a lower wage rate, or other factors of production through lower rates of return to those factors. The methods might involve simple partial equilibrium models, analytical general equilibrium models, or computable general equilibrium models. We review partial equilibrium models, where the burden of a tax is shown to depend on the elasticity of supply relative to the elasticity of demand. In particular, we consider partial equilibrium models with imperfect competition. Turning to a general equilibrium setting, we review the classic model of Harberger (1962) and illustrate its generality by applying it to a number of different contexts. We also use this model to demonstrate the practicality of analytical general equilibrium modeling through the use of log linearization techniques. We then turn to dynamic models to show how a tax on capital affects capital accumulation, future wage rates, and overall burdens. Such models might also provide analytical results or computational results. We also focus on relatively recent models that calculate the lifetime incidence of taxes, with both intratemporal and intertemporal redistribution. Finally, the chapter reviews the use of incidence methods and results in the policy process.

The Distribution of Tax Burdens: An Introduction

This paper summarizes important developments in tax incidence analysis over the past forty years. We mark the date of the beginning of modern tax incidence analysis with the publication of Harberger (1962) and discuss the relation of subsequent work to this seminal paper.

A Tax on Output of the Polluting Industry is Not a Tax on Pollution: The Importance of Hitting the Target

We explore the effects of environmental taxes that imprecisely target pollution. A review of actual policies indicates few (if any) examples of a true tax on pollution. More typically, environmental taxes target an input or output that is correlated with pollution. We construct a simple analytical general equilibrium model to calculate the optimum tax rate on the input of the polluting industry, in terms of key behavioral parameters, and we compare this imprecisely-targeted tax to an ideal tax on pollution. Finally, we consider incremental tax reforms such as a change in either tax from some pre-existing level. Using a utility-based money-metric measure of welfare, we examine the losses that arise from not taxing pollution directly. With no existing tax, under our plausible parameters, the welfare gain from an output tax is less that half the gain from an emissions tax.
