Environmental economics

Environmental economics is a sub-field of economics concerned with environmental issues.[1] It has become a widely studied subject due to growing environmental concerns in the twenty-first century. Environmental economics "undertakes theoretical or empirical studies of the economic effects of national or local environmental policies around the world. ... Particular issues include the costs and benefits of alternative environmental policies to deal with air pollution, water quality, toxic substances, solid waste, and global warming."[2]

Not to be confused with Ecological economics.

Environmental economics is distinguished from ecological economics in that ecological economics emphasizes the economy as a subsystem of the ecosystem with its focus upon preserving natural capital.[3] One survey of German economists found that ecological and environmental economics are different schools of economic thought, with ecological economists emphasizing "strong" sustainability and rejecting the proposition that human-made ("physical") capital can substitute for natural capital.[4]

History[edit]

The modern field of environmental economics has been traced to the 1960s[5] with significant contribution from Post-Keynesian economist Paul Davidson, who had just completed a management position with the Continental Oil Company.[6]

. Under this plan, the economic impact has to be estimated by the regulator. Usually, this is done using cost–benefit analysis. There is a growing realization that regulations (also known as "command and control" instruments) are not so distinct from economic instruments as is commonly asserted by proponents of environmental economics. E.g.1 regulations are enforced by fines, which operate as a form of tax if pollution rises above the threshold prescribed. E.g.2 pollution must be monitored and laws enforced, whether under a pollution tax regime or a regulatory regime. The main difference an environmental economist would argue exists between the two methods, however, is the total cost of the regulation. "Command and control" regulation often applies uniform emissions limits on polluters, even though each firm has different costs for emissions reductions, i.e., some firms, in this system, can abate pollution inexpensively, while others can only abate it at high cost. Because of this, the total abatement in the system comprises some expensive and some inexpensive efforts. Consequently, modern "Command and control" regulations are oftentimes designed in a way that addresses these issues by incorporating utility parameters. For instance, CO2 emission standards for specific manufacturers in the automotive industry are either linked to the average vehicle footprint (US system) or average vehicle weight (EU system) of their entire vehicle fleet. Environmental economic regulations find the cheapest emission abatement efforts first, and then move on to the more expensive methods. E.g. as said earlier, trading, in the quota system, means a firm only abates pollution if doing so would cost less than paying someone else to make the same reduction. This leads to a lower cost for the total abatement effort as a whole.

Environmental regulations

. Often it is advocated that pollution reductions should be achieved by way of tradeable emissions permits, which if freely traded may ensure that reductions in pollution are achieved at least cost. In theory, if such tradeable quotas are allowed, then a firm would reduce its own pollution load only if doing so would cost less than paying someone else to make the same reduction, i.e., only if buying tradeable permits from another firm(s) is costlier. In practice, tradeable permits approaches have had some success, such as the U.S.'s sulphur dioxide trading program or the EU Emissions Trading Scheme, and interest in its application is spreading to other environmental problems.

Quotas on pollution

. Increasing the costs of polluting will discourage polluting, and will provide a "dynamic incentive", that is, the disincentive continues to operate even as pollution levels fall. A pollution tax that reduces pollution to the socially "optimal" level would be set at such a level that pollution occurs only if the benefits to society (for example, in form of greater production) exceeds the costs. This concept was introduced by Arthur Pigou, a British economist active in the late nineteenth through the mid-twentieth century. He showed that these externalities occur when markets fail, meaning they do not naturally produce the socially optimal amount of a good or service. He argued that “a tax on the production of paint would encourage the [polluting] factory to reduce production to the amount best for society as a whole.”[16] These taxes are known amongst economists as Pigouvian Taxes, and they regularly implemented where negative externalities are present. Some advocate a major shift from taxation from income and sales taxes to tax on pollution - the so-called "green tax shift".

Taxes and tariffs on pollution

Better defined . The Coase Theorem states that assigning property rights will lead to an optimal solution, regardless of who receives them, if transaction costs are trivial and the number of parties negotiating is limited. For example, if people living near a factory had a right to clean air and water, or the factory had the right to pollute, then either the factory could pay those affected by the pollution or the people could pay the factory not to pollute. Or, citizens could take action themselves as they would if other property rights were violated. The US River Keepers Law of the 1880s was an early example, giving citizens downstream the right to end pollution upstream themselves if the government itself did not act (an early example of bioregional democracy). Many markets for "pollution rights" have been created in the late twentieth century—see emissions trading. According to the Coase Theorem, the involved parties will bargain with each other, which results in an efficient solution. However, modern economic theory has shown that the presence of asymmetric information may lead to inefficient bargaining outcomes.[17] Specifically, Rob (1989) has shown that pollution claim settlements will not lead to the socially optimal outcome when the individuals that will be affected by pollution have learned private information about their disutility already before the negotiations take place.[18] Goldlücke and Schmitz (2018) have shown that inefficiencies may also result if the parties learn their private information only after the negotiations, provided that the feasible transfer payments are bounded.[19] Using cooperative game theory, Gonzalez, Marciano and Solal (2019) have shown that in social cost problems involving more than three agents, the Coase theorem suffers from many counterexamples and that only two types of property rights lead to an optimal solution.[20]

Accounting for environmental externalities in the final price. In fact, the world's largest industries burn about $7.3 trillion of free natural capital per year. Thus, the world's largest industries would hardly be profitable if they had to pay for this destruction of natural capital. Trucost has assessed over 100 direct environmental impacts and condensed them into 6 key environmental performance indicators (EKPIs).[22] The assessment of environmental impacts is derived from different sources (academic journals, governments, studies, etc.) due to the lack of market prices. The table below gives an overview of the 5 regional sectors per EKPI with the highest impact on the overall EKPI:

[21]

Solutions advocated to correct such externalities include:


If companies are allowed to include some of these externalities in their final prices, this could undermine the Jevons paradox and provide enough revenue to help companies innovate.

Professional bodies[edit]

The main academic and professional organizations for the discipline of Environmental Economics are the Association of Environmental and Resource Economists (AERE) and the European Association for Environmental and Resource Economics (EAERE). The main academic and professional organization for the discipline of Ecological Economics is the International Society for Ecological Economics (ISEE). The main organization for Green Economics is the Green Economics Institute.
