Using a stacked differences-in-differences approach, we study the effects of Low Emission Zones (LEZs) in Germany. The implementation of stage 1 and 2 LEZs, which banned the most pollution-intensive vehicles from city centers, significantly reduced PM10 concentrations. The most restrictive third...

A two-region model is presented in which an imperfectly competitive firm produces a good with increasing returns at the plant level, and in which shipping costs exist between the two markets. Production of the good causes local pollution, and regional governments can levy pollution taxes or...

This paper is an introductory chapter to a book that brings together 22 of my papers written between 1965 and 1981. The chapter provides a summary of each paper and a more general discussion of the role of taxation in influencing the process of capita1 accumulation. The four sections of the book...

This chapter examines government policy alternatives for protecting the environment. We compare environmentally motivated taxes and various non-tax environmental policy instruments in terms of their efficiency and distributional impacts. Much of the analysis is performed in a second-best setting...

This paper uses analytical and numerical general equilibrium models to study the costs of achieving pollution reductions under a range of environmental policy instruments in a second-best setting with pre-existing factor taxes. We compare the costs and efficiency impacts of emissions taxes,...

We study the incidence of pollution taxes and their impact on unemployment in an analytical general equilibrium efficiency wage model. We find closed-form solutions for the effect of a pollution tax on unemployment, factor prices, and output prices, and we identify and isolate different channels...

This paper develops a simple model of a polluting industry and an innovating firm. The polluting industry is faced with regulation and costly abatement. Regulation may be taxes or marketable permits. The innovating firm invests in R&D and develops technologies which reduce the cost of pollution...

In recent years, cases in which state governments chose to override federal environmental regulation with tighter regulations of their own have become increasingly common, even for pollutants that have substantial spillovers across states. This paper argues that this change arose at least in...

This paper investigates whether an emissions tax (equivalent to an emissions cap) maximizes social welfare (defined as the sum of consumer and producer surplus) in the presence of incomplete regulation (leakage) or market power by analyzing an intensity standard regulating emissions per unit of...
