So let me turn to that part of the moral bedrock. Health is the capacity of the land for self-renewal. Why? Some states in the United States, as well as some developing countries, also use deposit-refund systems to assure that pesticide containers are returned after use. In Figure 5.2, because of discounting, the efficient allocation allocates somewhat more to Period 1 than to Period 2. Or maximize the equal distribution of welfare. What criteria might be proposed for evaluating predictions? Another quite different approach to promoting the use of renewable resources in the generation of electric power is known as a feed-in tariff. Economics of Water Resources: From Regulation to Privatization (Hingham, MA: Kluwer Academic Publishers, 1993). At those consumption rates, the aquifers supplying Tucson would have been exhausted in less than 100 years. In the absence of those steps, decisions that depend on private, not social, costs will inefficiently favor polluting sources. 119 Chapter 6 Depletable Resource Allocation FIGURE 6.1 A Categorization of Resources Total Resources Identified Undiscovered Demonstrated Inferred Economic Measured Hypothetical Speculative Indicated Reserves Submarginal Paramarginal Subeconomic 120 Terms Identified resources: specific bodies of mineral-bearing material whose location, quality, and quantity are known from geological evidence, supported by engineering measurements. What motivated the construction of inefficient projects? An efficient allocation would give Q0B to use B and Q 0A to use A. In your hometown what system is used to price the publicly supplied water? In fact, this study did not attempt to calculate the maximum net benefits outcome and if it had, it would have almost certainly discovered that the policy during this period was not optimal.

Holmes and Wiktor L. Adamowicz, “Attribute-Based Methods.” A PRIMER ON NONMARKET VALUATION, Ian Bateman, ed. 241 242 Chapter 10 A Locationally Fixed, Multipurpose Resource: Land Incompatible Land Uses As mentioned earlier in this chapter, the value of a parcel of land will be affected not only by its location, but also by how the nearby land is used. We should not, in other words, chop down all the trees and use up all the oil, leaving future generations to fend for themselves. Senator John Kerry, on the other hand, sought to promote a much larger role for energy efficiency and energy conservation. Many of the significant effects do not appear for a long time. 117 6 Depletable Resource Allocation: The Role of Longer Time Horizons, Substitutes, and Extraction Cost The whole machinery of our intelligence, our general ideas and laws, fixed and external objects, principles, persons, and gods, are so many symbolic, algebraic expressions. While most scientists now agree on the potential impacts of climate change, such as sea level rise and species losses, the timing and extent of those losses are not certain. Shares in the project are transferable and the Northern Colorado Water Conservancy District (NCWCD) facilitates the transfer of these C-BT shares among agricultural, industrial, and municipal users. (2008) found that colored photographs, as opposed to black-and-white photographs, influence respondent willingness to pay for the Philippine Eagle. How useful is that calculation? Because price controls would cause prices to be lower than efficient, the resource would be depleted too fast. So at this point I’m raising a question rather than offering an answer: is an outcome with a flourishing environment intrinsically better, ceteris paribus, than one without, and if so what exactly does a flourishing environment mean here? The premise that societies can germinate the seeds of their own destruction has long fascinated scholars. However, in order to price water efficiently, user volume must be measured. The answers may surprise you. Both the level of prices and the rate structure are at fault. TABLE 8.3 Electronics Recycling Rates 2006–2007. This restraint results in lower costs in the form of less time and effort expended to produce a given yield of bison. p. cm. Now, the intuition may be wrong, but at a minimum anyone grappling with the foundations of environmental law needs to grapple with the possibility that ecosystems, species, and other aspects of the environment might have intrinsic moral significance—within consequentialism, no less. I don’t say this out of a general moral skepticism, since I think that some moral norms or criteria really exist. This approach is appropriate if society is risk-neutral. In some circumstances they are, but certainly not in all, or even most, circumstances. Only if the user cost of that water is imposed on current users will the proper incentive for conservation be created and the interests of future generations of water users be preserved. We might expect the answer for the problem of nuclear accidents to be no, because this seems to be such a clear case of externalities. first-come, first-served basis and the occupiers, called “squatters,” do not actually hold title to the land. Used batteries supply about 90 percent of that old scrap. In particular, it considers the role that economics might play in environmental issues and how economics … As Example 9.4 demonstrates, reserving water for instream uses has created controversy on more than one occasion. By 1955, only eight years later, U.S. News and World Report concluded that worry over the scarcity of iron ore could be forgotten. Market Power Special Problems in Developing Countries DEBATE 10.2 What Is a “Public Purpose”? With formal enforceable property rights, current users could legally defend their interests. GIS technology enhanced this study by facilitating the calculation of the distance from each home to both the river and the nearby dams. Many areas have attempted to increase the amount of recycled waste lubricating oil by requiring service stations to serve as collection centers or by instituting deposit-refund systems. In this text, we tackle some of the complex issues that face our globe and explore problems and potential solutions. While some of these may also plague developing countries, we follow with a section that looks specifically at some special problems developing countries face. Knowledge of how the value of each site varies with respect to its characteristics allows the analyst to value how degradation of those characteristics (e.g., from pollution) would lower the value of the site. Specific circumstances that could lead to inefficient allocations include externalities; improperly defined property rights systems (such as open-access resources and public goods); and imperfect markets for trading the property rights to the resources (monopoly). Not all price controls are permanent; they can change unpredictably at the whim of the political process. Using these, we obtain 8 - 0.4q1 - 2 - l = 0, (1) 8 - 0.4q2 - 2 (2) 1.10 - l = 0 q1 + q2 = 20. Figure 9.2 shows how surface- and groundwater withdrawals for the United States vary by state. I’m not going to speak to them here. Suppose we have two versions of the two-period model, discussed in this chapter, that are identical except for the fact that the second version involves a higher demand for the resource in the second period (the demand curve shifts to the right due to population growth) than the first version. In this example, prices do not adjust to reflect the increasing waste load. Other economists, such as William Nordhaus of Yale University, who prefer a discount rate around 6 percent, believe that optimal economic policies to slow climate change involve only modest rates of emissions reductions in the near term, followed by sharp reductions in the medium and long term. To answer this question, a national contingent valuation survey (this technique is outlined in the next section) was conducted to estimate the nonuse value of preservation in this case. One could have a pluralist view, incorporating overall welfare, distributive concerns, deontological rights, and environmental or aesthetic values detached from welfare. In the United States, damage estimates are not only used in the design of policies, but, as indicated in the opening paragraphs of this chapter, they have also become important in the courts. In applying property rules, the court merely decides which right is preeminent and places an injunction against violating that right. Meaning of Externality 2. 223 224 Chapter 9 Replenishable but Depletable Resources: Water EXAMPLE 9.4 Reserving Instream Rights for Endangered Species The Rio Grande River, which has its headwaters in Colorado, forms the border between Texas and Mexico. 101, No. Crafting Institutions for Self-Governing Irrigation Systems (San Francisco: ICS Press, 1992). Does that seem the right choice? Geothermal heat pumps are similar to ordinary heat pumps, but they use the geothermal water resource instead of outside air as the input source for the pump.) Additionally, many of the published studies do not provide enough information on the attributes to allow an assessment of how they might have affected the derived value. We will return to this example later. 68, No. New scrap is composed of the residual materials generated during production. In Canada, the practice is not common either (see Example 9.5). How would the market allocation, based on only the former cost, differ from the efficient allocation, which is based on both costs? Or alternatively, the VSL can be calculated using the change in WTP divided by the change in risk. Title: Environmental and natural resource economics. Those in the second period would be better off by accepting the dynamic efficient allocation with sharing than they would if they demanded that resources be allocated equally between the two periods. Over time, population pressure and the infusion of outsiders raised demand and undermined the collective cohesion sufficiently that the traditional rules became unenforceable, producing overexploitation of the resource and lower incomes for all the participants. Resource use by previous generations should not exceed a level that would prevent subsequent generations from achieving a level of well-being at least as great. The possibilities are presented in Table 4.1. For example, draining, dredging, filling, and flooding are frequently prohibited in shoreland wetlands. On the other hand, when the social opportunity cost of capital differs from this administratively determined level, the benefit–cost analysis will not, in general, define the efficient allocation. Armed with this information, we can estimate the expected present value of net benefits. A rather different context for normative economics can arise when the possibilities are more open-ended. Global Water Intelligence, Vol. The dynamically efficient allocation of this resource has to satisfy the condition that the present value of the marginal net benefit from the last unit in Period 1 equals the present value of the marginal net benefit in Period 2 (see appendix at the end of this chapter). One fascinating public policy area where these various approaches have been applied is in the valuation of human life. Such a system is already employed in Sweden and Norway to counter the problem of abandoned automobiles. This contrasts sharply with changes in which the gains to the gainers are smaller than the losses to the losers. The act also allows water transfers to new uses. To be sure, this override power needs to be exercised cautiously, since people are often the best judges of their own welfare. 4 (1995), pp. And, as we have already seen, the discount rate is a major determinant of the allocation of resources among generations as well. For example, the U.S. EPA provides guidelines on distributional issues in its “Guidelines for Preparing Economic Analysis.” According to the EPA, distributional analysis “assesses changes in social welfare by examining the effects of a regulation across different sub-populations and entities.” Distributional analysis can take two forms: economic impact analysis and equity analysis. The bottom line is that both the type of fuel produced and the type of biomass used to produce it matter. 22, No. Another challenge in this model is how to incorporate the opportunity cost of time. The effect of this external cost on the steel industry is illustrated in Figure 2.5, which shows the market for steel. Jenkins, Robin R. The Economics of Solid Waste Reduction: The Impact of User Fees (Cheltenham, UK: Edward Elgar, 1993). Examples include fish harvested from the sea, timber harvested from the forest, water extracted from 79 80 Chapter 4 Valuing the Environment: Methods a stream for irrigation, even the scenic beauty conferred by a natural vista. Easter, K. William, M. W. Rosegrant, and Ariel Dinar, eds. Negotiation is also difficult to apply when the number of people affected by the pollution is large. Suppose, for example, that the extraction of the depletable resource caused some damage to the environment that was not adequately reflected in the costs faced by the extracting firms. The market would be using less of the resource—due to higher price—while recycling more. 16 (2000): 239–251. of at least the same order [of magnitude] as major competing land uses, and infinitely greater than that recognized by most governments (i.e., zero). ZERO! Second we will attempt to discern the extent to which our institutions produce optimal outcomes and, where divergences occur between actual and optimal outcomes, to attempt to uncover the behavioral sources of the problems. By early in the sixth century, however, the carrying capacity of the most productive local lands was exceeded, and farmers began to depend upon more fragile parts of the ecosystem. Since their last survey in 2007–2008, the number of increasing or inverted block rates has risen. (Why?) If the present value is greater than zero, the action should be supported. The public sector could simply buy the land from its current owner of course and that approach has much to recommend it. The nature of the information that is available and its reliability make a difference. Suppose, however, as is commonly the case, that the extensions of these services are financed by metropolitan-wide taxes. To provide some context for those numbers, gains from trade in Chile are estimated to be between 8 and 32 percent of agricultural contribution to GDP. Topography matters, of course, but so does its location, especially since in contrast to many other resources, land’s location is fixed. Perhaps the public should be willing to share some of the preservation costs by allocating tax dollars to this area to facilitate the transition and to reduce the hardship. Using the higher income elasticity number is merited since willingness to pay for mortality risk reduction as a percentage of income drops at very low incomes; what limited income is available in poorer households is reserved for basic needs. The sources of scrap may be concentrated around cities where most of the products are used, while for historical reasons the processing facilities are near the sources of the virgin ores. The similarity of this case to the increasing-cost, depletable-resource model discussed in Chapter 6 allows us to exploit that similarity to learn something about the efficient allocation of groundwater over time. The fee was $3 or $4 per can (depending upon the number). The general conclusion, which holds for all models we consider, is that higher discount rates tend to skew resource extraction toward the present because they give the future less weight in balancing the relative value of present and future resource use. Hausman, Jerry A., ed. Tsur et al. Source: The Alaska Permanent Fund Web site: http://www.pfd.state.ak.us/ Applying the Sustainability Criterion One of the difficulties in assessing the fairness of intertemporal allocations using this version of the sustainability criterion is that it is so difficult to apply. E-Waste Recognizing the dangers from improperly disposed electronic equipment (e-waste), some states have enlisted economic incentives to promote recycling. That’s Martha Nussbaum’s list, which I find fairly plausible.9 Objective goods, more formally, are not things that people actually prefer. The first involves the incentives for polluting that result when the property right is assigned to the polluter. Since precipitation, runoff, and evaporation all change from year to year, in some years less water will be available for allocation than in others. Electricity Forcing generators to compete for customers, it was believed, would produce lower electricity bills for customers. 3. At the end of the second year, 90 percent of the remaining 90 units could once again be recovered, leaving 81 units for the third year, and so on. Over the course of a century, first colonizers and then, after independence, the Nauruans decided to extract massive amounts of this rock. The traditional means of determining when that test has been satisfied is to require that the current owners be sufficiently compensated that they would voluntarily give up their land. This way, all points along the horizontal axis yields a total of 20 units The height of the triangle is $6 [$8–$2] and the base is 15 units. For other materials, recycling rates are on the rise. 5 6 Chapter 1 Visions of the Future How Will Societies Respond? Utilitarianism is a limiting case of prioritarianism, where the welfare weights are equal across persons. For the increasing marginal-extraction-cost model of the allocation of a depletable resource, how would the ultimate cumulative amount taken out of the ground be affected by (a) an increase in the discount rate, (b) the extraction by a monopolistic, rather than a competitive, industry, and (c) a per-unit subsidy paid by the government for each unit of the abundant substitute used? A close examination of the total-marginal-cost path reveals two interesting characteristics worthy of our attention. (Washington, DC: Resources for the Future, Inc., 2003). Decision makers at that time had to decide whether it should be mined or preserved. Without a good measure of benefits, making an efficient choice is no longer possible. When the property right is assigned to the steel company, the cost is borne by the resort (part of the cost is the damage and part is the bribe to reduce the level of damage). Applying the Concepts This approach has the substantial virtue that it weighs higher probability outcomes more heavily. If you used one of your senses to experience the resource—sight, sound, touch, taste, or smell—then you have used the resource. If minerals are discovered in a claim area and at least $500 has been invested in development or extraction, the land could actually be bought for $5 an acre on lode claims or $2.50 an acre on placer claims. Nonwelfarist consequentialisms, which might sometimes require regulators or other actors to make everyone worse off, are, I think, perfectly thinkable moral views. Are you planning to go to Yellowstone National Park next summer? Unique circumstances may cause the costs of that firm to be higher, or lower, than estimated; the firm, in short, may not be typical. This notion gives rise to three alternative definitions of sustainable allocations: Weak Sustainability. 35, No. Typically, peaking units are cheaper to build than baseload plants, but they have higher operating costs. An Efficient Allocation of Recyclable Resources Extraction and Disposal Cost How would an efficient market, one devoid of any imperfections, allocate a recyclable depletable resource? The study of economics can assist in identifying circumstances that give rise to environmental problems, in discovering causes of these problems, and in searching for solutions. Many employers provide free employee parking even though providing that parking is certainly not free to the employer. (Note the contrast between commonpool resources and public goods, the subject of the next section.) Why? In Figure 2.10, we showed that if the steel company has the property right, it is in the resort’s interest to offer a bribe that results in the desired level of output. Many states are now imposing severance taxes on resources being extracted within their borders. Why? Suppose it could pollute only if it compensated the resort for all damages. Debate 9.1 illustrates the inconsistencies in both agricultural and municipal pricing. We recognize that these assumptions introduce significant uncertainty into the cost results; however, the degree of uncertainty or bias associated with many of the key factors cannot be reliably quantified. (2002). 2 The monetary worth of the net benefit is the sum of two right triangles, and it equals (1/2)($5)(5) + (1/2)($2.50)(5) or $18.75. Why or why not? xxviii Preface Finally, Tom would like to express publicly his deep appreciation to his wife Gretchen, his daughter Heidi, and his son Eric for their love and support. Bribes are, of course, not the only means victims have at their disposal for lowering pollution. As the natural gas is extracted and stored, unless the helium is simultaneously captured and stored, it diffuses into the atmosphere. The State of Maine was 10 Several examples of the use of meta-analysis and benefit transfer are given in Florax et al. Perhaps those same cities averaged older populations, which would tend to lead to higher death rates. Assume that the amount of some input Y (a depletable resource) is reduced from Y1 to Y2. The private marginal cost curve shifts down and to the right causing a further increase in production, lower prices, and even more pollution produced. VSL rises with age, peaks, and then declines. They find that the higher transactions costs in the Arkansas River Basin result in fewer, but larger, transactions than for the South Platte and NCWCD. One policy approach for dealing with these concerns involves renewable energy credits (RECs). Title. What would be the global cost of losing or reducing this valuable ecosystem service? He examined the benefits and costs of constructing the Big Thompson Project in northeastern Colorado. Using economic analysis, figure out what the effects of the Bush and Kerry strategies would be on (1) oil prices in the short run and the long run, (2) emissions affecting climate change, and (3) U.S. imports in the short run and the long run. Does their analysis mean that benefit–cost analysis is fatally flawed? The market works inefficiently because the product users do not bear the full marginal social costs of disposing of their product. Suppose your city provides trash pickup for which you pay $150 a year in taxes. Why or why not? Attempts to solve environmental problems that ignore these forces run a high risk of failure. The problem with this approach is that water suppliers in many areas can act as a monopoly, using their power to raise rates beyond competitive levels, even if those rates are, in principle, subject to regulation. 2 The condition that marginal user cost rises at rate r is true only when the marginal cost of extraction is constant. One journal, Ecological Economics, is dedicated to bringing economists and ecologists closer together in a common search for appropriate solutions for environmental challenges.

These conflicts become intensified if unemployment rates in the area are high and the local ecology is rather unique. 9780415, This page intentionally left blank “Discounting and Environmental Management,” in T. Tietenberg and H. Folmer, eds. 5 Note that the aesthetic value from open space is a public good. Perhaps the most significant role for conservation is its ability to defer capacity expansion. A one billion barrel stockpile would replace three million barrels a day for slightly less than one year or a larger number of barrels per day for a shorter period of time. The manner in which scholars in various disciplines view problems and potential solutions depends on how they organize the available facts, how they interpret those facts, and what kinds of values they apply in translating these interpretations into policy. Thus, the useful stock of helium depends crucially on how much we decide to store. Attempts to protect instream water uses must confront two problems. Tangible versus Intangible Benefits. It is far from clear what the ultimate mix will turn out to be, but it is very clear that government policy is a necessary ingredient in any smooth transition to a sustainable-energy future. In 1997 the USGS estimated subsidence amounts of 6 feet in Las Vegas, 9 feet in Houston, and approximately 18 feet near Phoenix. But of course the claim that the welfare benefits of environmental regulation will always justify the welfare costs isn’t true at the margin, and invoking costs to future generations raises other puzzles—for example, discounting puzzles and nonidentity puzzles (whether a policy that changes who exists in the future should be seen as having costs or benefits beyond the present generation). Accounting Stance. One unconventional source of both oil and natural gas is shale. They also illustrate the point that, in this case, marginal user cost rises over time. Why would we want any imports at all when national security is at stake? Raising the Real Cost of Fishing Taxes Individual Transferable Quotas (ITQs) and Catch Shares EXAMPLE 13.3 The Relative Effectiveness of Transferable Quotas and Traditional Size and Effort Restrictions in the Atlantic Sea Scallop Fishery Subsidies and Buybacks Marine-Protected Areas and Marine Reserves The 200-Mile Limit The Economics of Enforcement Preventing Poaching DEBATE 13.2 Bluefin Tuna: Is Its High Price Part of the Problem or Part of the Solution? Every year, several states either have proposed new legislation or proposed expansions of existing legislation. While these processes have already begun, they will intensify slowly throughout the century. This distinction implies that when a land-intensive activity, such as farming, is located in an area under significant development pressure, the tax assessment may reflect the development potential of the land, not its value in farming. Water scarcity is not merely a problem to be faced at some time in the distant future. Privatization of water supplies creates the possibility of monopoly power and excessive rates, but privatization of access rights (such as discussed in Example 9.1 and Debate 9.2) does not. Tackles the tricky question of how one can tell whether development is sustainable or not. It provides a means for maximizing the wealth derived from all the possible sustainable allocations. “A Review of the Stern Review on the Economics of Climate Change,” Journal of Economic Literature Vol. This demonstrates the proposition shown graphically in Figure 5.2. This supply-side effect tends to hasten the time when a switch to the renewable resource is made, all other things being equal. To minimize this cost, more of the burden of the shortfall is allocated to B than A. Assume that in the second version the constant marginal extraction cost is lower in the second period than the first (perhaps due to the anticipated arrival of a new, superior extraction technology). In the presence of close substitutes, WTP and WTA should not be that different, but the divergence between the two measures should increase as the degree of substitution decreases (Hanemann, 1991; Shogren et al., 1994). Strategic bias arises when the respondent provides a biased answer in order to influence a particular outcome. The EIA’s own estimates of the timing range from 2031 to 2068 (Caruso, 2005). What was the effect of this regulation? No. There was a significant Market Allocations of Depletable Resources percentage of taconite ore available containing less than 30 percent iron in crude form, but no one knew how to produce it at reasonable cost. The net benefit curve intersects the vertical axis at $6; demand would be zero at $8 and the marginal cost is $2, so the difference (marginal net benefit) is $6. In the long run when all costs are variable, producer’s surplus is equal to profits plus rent, the return to scarce inputs owned by the producer. As mentioned earlier in this chapter, the Colorado-Big Thompson (C-BT) Project moves water from the Colorado River to the eastern slope of Colorado. But the fact that these are powerful and useful tools in the quest for a sense of harmony between the economy and the environment does not imply that they are the only criteria in which we should be interested.
