Students are introduced to the concept of the externality, the Coase theorem and the importance of property rights as a determinant of market failure. Alternative revelation methods for determining the value of public goods are presented. The optimality of the Pigouvian tax based solution is derived and contrasted to other regulatory methods of pollution control including tradable permits, environmental subsidies and command and control. The proper implementation of these measures is explored within the context of imperfect competition, imperfect mixing, imperfect monitoring ability, uncertainty and tax interaction effects. The final part of course also deals with the monitoring and enforcement of environmental regulations; and the ex-post regulation of environmental hazards using strict and negligence based liability versus ex-ante standards. The module will demonstrate how economic growth and an expansion of international trade affect the quality of the environment and the scale of pollution.
Students are also introduced to a variety of revealed preference methods of valuation including: hedonic pricing; travel cost methods; and the household production function approach. Students are also taught stated preference methods of benefits determination including contingent valuation and choice experiments. The teaching includes both familiarising students with the microeconomic foundations for the alternative techniques and with the empirical implementation of the techniques using real-world data and appropriate parametric and non-parametric statistical techniques. Students are made aware of the methodological controversies surrounding the use of these techniques including the discrepancy between Willingness to Pay and Willingness to Accept; as well as the debate about existence values.
Learning Outcomes
By the end of the module students should be able to:
Understand the role of property rights as determinants of environmental degradation and apprehend the economic arguments in favour of particular forms of environmental regulations and how these are modified by problems relating to market structure, uncertainty and non-observability of polluting activities
Understand the economic issues underlying monitoring and enforcement, the relative advantages of ex-ante regulations and legal liability for dealing with environmental hazards and be able to comment critically on contemporaneous environmental issues from an economics perspective
Appreciate the strengths and weaknesses of alternative non-market valuation techniques and understand fully the microeconomic foundations of these techniques
critically comment on studies employing valuation techniques and be aware of the methodological controversies surrounding their use and be capable of conducting a valuation experiment and econometrically analysing the results
