Energy Efficiency Economics and Policy

Abstract: Energy efficiency and conservation are considered key means for reducing greenhouse gas emissions and achieving other energy policy goals, but associated market behavior and policy responses have engendered debates in the economic literature. We review economic concepts underlying consumer decision making in energy efficiency and conservation and examine related empirical literature. In particular, we provide an economic perspective on the range of market barriers, market failures, and behavioral failures that have been cited in the energy efficiency context. We assess the extent to which these conditions provide a motivation for policy intervention in energy-using product markets, including an examination of the evidence on policy effectiveness and cost. Although theory and empirical evidence suggests there is potential for welfare-enhancing energy efficiency policies, many open questions remain, particularly relating to the extent of some key market and behavioral failures.

The Economics of Genetically Modified Crops

Abstract: Genetically modified (GM) crops have been used commercially for more than 10 years. Available impact studies of insect-resistant and herbicide-tolerant crops show that these technologies are beneficial to farmers and consumers, producing large aggregate welfare gains as well as positive effects for the environment and human health. The advantages of future applications could even be much bigger. Given a conducive institutional framework, GM crops can contribute significantly to global food security and poverty reduction. Nonetheless, widespread public reservations have led to a complex system of regulations. Overregulation has become a real threat for the further development and use of GM crops. The costs in terms of foregone benefits may be large, especially for developing countries. Economics research has an important role to play in designing efficient regulatory mechanisms and agricultural innovation systems.

Agriculture for Development: Toward a New Paradigm

Abstract: The fundamental role that agriculture plays in development has long been recognized. In the seminal work on the subject, agriculture was seen as a source of contributions that helped induce industrial growth and a structural transformation of the economy. However, globalization, integrated value chains, rapid technological and institutional innovations, and environmental constraints have deeply changed the context for agriculture's role. We argue that a new paradigm is needed that recognizes agriculture's multiple functions for development in that emerging context: triggering economic growth, reducing poverty, narrowing income disparities, providing food security, and delivering environmental services. Yet, governments and donors have neglected these functions of agriculture with the result that agriculture growth has been reduced, 75% of world poverty is rural, sectoral income disparities have exploded, food insecurity has returned, and environmental degradation is widespread, compromising sustainability...

Integrating Ecology and Economics in the Study of Ecosystem Services: Some Lessons Learned

Abstract: This paper discusses both the opportunities for and the challenges associated with integrating economics and ecology in the study of ecosystem services. We distinguish between integration in positive versus normative analysis. There is rapid growth in positive research that combines the two disciplines to provide insight and better understanding of the bidirectional linkage between economic and ecological systems. This research is a crucial part of addressing growing large-scale environmental challenges. This integration is equally important, but potentially much more difficult, in normative analysis, especially when interdisciplinary groups include individuals with different views regarding appropriate normative criteria. In such cases, reaching consensus can be difficult and slow, even when the practical implications of the different perspectives (i.e., the general policy prescriptions they imply) are the same. We suggest an approach for increasing the scope for collaboration among economists and ecologists in normative analysis.

Behavior, Environment, and Health in Developing Countries: Evaluation and Valuation

Abstract: We consider health and environmental quality in developing countries, where limited resources constrain behaviors that combat enormously burdensome health challenges. We focus on four huge challenges that are preventable (i.e., are resolved in rich countries). We distinguish them as special cases in a general model of household behavior, which is critical and depends on risk information. Simply informing households may achieve a lot in the simplest challenge (groundwater arsenic); yet, for the three infectious situations discussed (respiratory, diarrhea, and malaria), community coordination and public provision may also be necessary. More generally, social interactions may justify additional policies. For each situation, we discuss the valuation of private spillovers (i.e., externalities) and evaluation of public policies to reduce environmental risks and spillovers. Finally, we reflect on open questions in our model and knowledge gaps in the empirical literature including the challenges of scaling up and...

The Economics of Urban-Rural Space

Abstract: The emergence of urban-rural space, as evidenced by the expansion of low-density exurban areas and growth of amenity-based rural areas, is characterized by the merging of a rural landscape form with urban economic function. Changing economic conditions, including waning transportation and communication costs, technological change and economic restructuring, rising real incomes, and changing tastes for natural amenities, have led to this new form of urban-rural interdependence. We review the recent research on the causes and consequences of this growth at regional and metropolitan scales, discuss advances in empirical and theoretical economic models of urban land-use patterns at spatially disaggregate scales, and highlight research on environmental impacts and the efficacy of growth controls and land conservation programs that seek to manage this growth. The paper concludes with future research questions and needs. These include spatially disaggregate and accurate data, improved causal inference and struct...

Whither Hotelling: Tests of the Theory of Exhaustible Resources

Abstract: We review the empirical literature that extends and tests the Hotelling model of the optimal depletion of an exhaustible resource. The theory is briefly described to set the stage for the review of empirical tests and applications. Those tests can be roughly divided into two broad categories—descriptive and structural—and we discuss the strengths and weaknesses of each before presenting the empirical studies of optimal extraction under conditions of exhaustibility. We also discuss some econometric pitfalls that applied researchers face when attempting to test the model.

Fuel Versus Food

Abstract: Many countries have actively encouraged the production of biofuels as a low-carbon alternative to the use of fossil fuels in transportation. To what extent do these trends imply a reallocation of scarce land away from food to fuel production? This paper critically reviews the small but growing literature in this area. We find that an increase in biofuel production may have a significant effect on food prices and, in certain parts of the world, in speeding up deforestation through land conversion. However, more research needs to be done to examine the effect of newer generation biofuel technologies that are less land intensive as well as the effect of environmental regulation and trade policies on land-use patterns.

Supply and Demand of Electricity in the Developing World

Abstract: This paper reviews the literature that has sought to quantify the determinants of electricity demand and supply efficiency in developing countries. We examine the causal relationship between electricity consumption and economic growth, price and income elasticities of demand, and the barriers to adoption of energy-efficient equipment. We also examine the performance outcomes of economic policies affecting the electricity sector, including institutional reforms such as privatization and regulation. We find that electricity demand is driven by GDP, prices, income, the level and characteristics of economic activity/urbanization, and seasonal factors. The magnitude of their effects differs across countries, time periods, and studies even for the same country. These demand studies suffer from a number of limitations, including data availability and price distortions that limit responsiveness of demand to price signals. The literature is inconclusive on whether reforms, particularly privatization, improved supp...

The Curse of Natural Resources

Abstract: A large literature has developed that documents a negative association between the presence of natural resources and economic development. In this paper we explore the empirics and theories of the so-called resource curse and try to assess its robustness. We conclude that there are many open questions and that the case of the curse needs revision and nuance.

The Economics of Agricultural R&D

Abstract: Agricultural research has transformed agriculture and in doing so contributed to the transformation of economies. Economic issues arise because agricultural research is subject to various market failures, because the resulting innovations and technological changes have important economic consequences for net income and its distribution, and because the consequences are difficult to discern and attribute. Economists have developed models and measures of the economic consequences of agricultural R&D and related policies in contributions that relate to a very broad literature ranging across production economics, development economics, industrial organization, economic history, welfare economics, political economy, econometrics, and so on. A key general finding is that the social rate of return to investments in agricultural R&D has been generally high. Specific findings differ depending on methods and modeling assumptions, particularly assumptions concerning the research lag distribution, the nature of the r...

Reduced-Form Versus Structural Modeling in Environmental and Resource Economics

Abstract: We contrast structural and reduced form empirical studies in environmental and resource economics. Both methodologies have their own context-specific advantages and disadvantages, and should be viewed as complements, not substitutes. Structural models typically require a theoretical model and explicit assumptions about structural errors in order to recover the parameters of behavioral functions. These estimates may be required to measure general equilibrium welfare effects or to simulate intricate feedback loops between natural and economic processes. However, many of the assumptions used to recover structural estimates are untestable. The goal of reduced form studies is, conversely, to recover key parameters of interest using exogenous within-sample variation with as few structural assumptions as possible—reducing reliance on these assumptions assists in establishing causality in the relationship of interest. Reduced-form studies do, however, require assumptions of their own, e.g., the (quasi) randomness...

Integrated Ecological-Economic Models

Abstract: Scientific evidence suggests that economic activity is threatening global biodiversity in ways that could severely degrade nature's flow of ecosystem services. Yet, there is relatively little work in economics that addresses biodiversity loss. Some economists have called for better integration of economic and ecological models to address biodiversity and the attendant ecosystem services. Current integrated approaches in economics are discussed, and they take in ecosystem services, ecosystem externalities, and substantial ecological modeling. Much of the modeling uses Lotka-Volterra equations, which are standard in ecology, although there is concern that the equations lack the microfoundations of plant and animal behavior. An alternative approach is to admit microbehavior using economic optimization techniques that build adaptive ecological systems. However, much more effort is needed to assess whether admitting more ecological detail into economic models will be fruitful.

Land Use and Climate Change Interactions

Abstract: Land use and land-use change can result in the emissions of greenhouse gases that cause climate change. Climate change also affects the productivity of land, which in turn leads to further land-use change. This paper explores the growing research on both topics. The land-use emission literature has focused on deforestation (harvests) and ignored the fact that harvests have led to a much younger and therefore growing global forest. Taking this into account, mankind’s current and future influence over land use will have a small positive effect on reducing greenhouse gas emissions. Although the literature initially focused on climate impacts alone, when adaptation is taken into account we find that climate change is likely to have benign net global impacts on market sectors related to land use. Climate impacts on nonmarket sectors, however, are much more poorly understood or measured. Furthermore, it is not yet clear whether governments will adapt or maladapt to climate change.

Environmental Regulations and Economic Activity: Influence on Market Structure

Abstract: We survey recent developments in the theoretical and empirical literature on the economic effects of environmental regulation on various aspects of market structure including entry, exit, and size distribution of firms and market concentration.

Recent Developments in the Intertemporal Modeling of Uncertainty

Abstract: Time and uncertainty constitute essential ingredients to many of the most challenging resource problems. With respect to the time dimension, agents are generally assumed to have a pure time preference as well as a preference for smoothing consumption over time. With respect to risk, agents are generally assumed to be Arrow-Pratt risk averse. The discounted expected utility model assumes that aversion to risk and aversion to intertemporal fluctuations coincide. This review discusses models and concepts that aim at disentangling time and risk attitude and briefly sketches a generalization of risk attitude to situations where uncertainty is not captured by unique probability measures. This paper reviews resource economic applications and relates the concepts to the debate on the social discount rate.

Experiments in Environment and Development

Abstract: Many of the main scientific challenges in the fields of development, environment, and resource economics have a microeconomic foundation wherein behavioral elements play a significant role. Preferences with respect to risk, time, societal others, and the environment shape the decision-making processes of individuals. Economic experiments have been extensively carried out in the lab and in the field to test the predictions of behavioral theories; some have had a particular focus on development and environmental issues. Random interventions have also proven to be an important source of information with respect to experimentation in development and policy design. This article identifies the contributions of experiments and random interventions and reflects on the value of having a productive dialogue—in connection with said experiments—with the main stakeholders regarding the problems being studied.

Recent Developments in Renewable Technologies: R&D Investment in Advanced Biofuels

Abstract: Investment in renewable energy, both in research and development and in commercial production, has risen significantly during the current decade. Although a variety of different renewable sources have been targeted for expansion, biomass technologies, especially those for converting biomass to liquid biofuels for transportation, have cornered a large share of the new investments. Cutting-edge knowledge in genomics and biotechnology, process chemistry, and engineering is being applied to produce new types of energy feedstock and process them into novel biofuels. If these investments bear fruit, liquid biofuels have the potential to displace a substantial amount of oil over the next few decades, with limited negative impact on food supply and the natural habitat. Energy-security and food-security constraints and environmental considerations will determine which technologies emerge as winners. The search for new transportation fuels is also giving rise to the development of new paradigms in innovation, commercialization, and regulation.

The Economics of Endangered Species

Abstract: Because habitat conversion is the greatest threat to species, this article focuses on economic incentives for private land users to protect habitat. Habitat protection policies that fail to account for private incentives often have unintended negative consequences. Private incentives for habitat protection depend on many factors: whether landowners are compensated for the costs of habitat protection, the design of compensation mechanisms, underlying property rights and security of tenure, the structure of conservation contracts, and whether markets can be created that internalize external benefits of habitat protection. In developing countries, agricultural price, credit, tax, and land tenure policies have important effects on the demand for habitat conversion. Private landowners often can provide crucial information about costs of habitat protection and species or habitat values on their property. Policies that encourage self-reporting of this information can greatly improve the cost effectiveness of pol...

Irreversibility in Economics

Abstract: Three independent literatures have contributed to the understanding of irreversibility in economics. The first focuses on the future opportunities forgone by investments with irreversible consequences. The second considers irreversibility (and hysteresis) in the context of the dynamics of systems characterized by multiple equilibria. The third, with roots in complex systems theory, focuses on entrainment—a phenomenon recognized in economics as lock-in or lock-out. This paper disentangles the different strands in the economic analysis of irreversibility in order to identify the core ideas involved and to connect them to arguments in the parallel literatures on sustainability and uncertainty.

The Development of New Catastrophe Risk Markets

Abstract: The large-scale disasters that have occurred since 2001 suggest that we have entered a new era of catastrophes. We are more vulnerable to extreme events as a result of the increasing concentration of population and activities in exposed areas of the country. The question is not whether large-scale catastrophe will occur, but when and how frequently they will strike. One key question is, Who will pay for the economic losses future disasters will inflict? This paper discusses how new catastrophe risk markets can be developed to provide the necessary financial coverage to make our country more resilient. We look specifically at insurance-linked financial instruments to complement traditional insurance and reinsurance. We also propose the development of long-term insurance and long-term loans to overcome behavioral biases such as myopia and misperception of risks. The paper concludes by proposing risk management strategies that apply to other extreme events such as the financial crisis of 2008–2009.

On the economics of water allocation and pricing.

Abstract: I present the economic principles of water allocation and pricing in a schematic water economy representing a wide range of real-world situations. The water policy has inter- and intratemporal components. The former determines extractions from the naturally replenished sources, given the stochastic nature of recharge processes. The latter is concerned mainly with the allocation of the extracted and produced water among the end users. The optimal water prices associated with the intratemporal allocation task are derived. Implementation of the optimal policy is discussed.

Pricing Urban Congestion

Abstract: This paper reviews literature on the optimal design of pricing policies to reduce urban automobile congestion. The implications of a range of complicating factors are considered; these include traffic bottlenecks, constraints on which roads and freeway lanes in the road network can be priced, driver heterogeneity, private toll operators, other externalities besides congestion, and interactions between congestion taxes and the broader fiscal system. I also briefly discuss the incidence of congestion taxes and experience with this policy in the United States and elsewhere. Although the economics literature on congestion pricing has advanced considerably over the past 20 years, research is still needed on the empirical measurement of second-best efficient tolls for urban centers and whether alternative design features have substantial implications for efficiency. More research is also needed on the design of schemes to promote feasibility by compensating adversely affected groups with minimal loss in economi...

Public-Private Partnerships: Goods and the Structure of Contracts

Abstract: This paper presents a framework for analyzing the structure of contracts for public-private partnerships (PPP) that produce products and services that generally include mixtures of both public and private goods. A three-stage framework, sourced with the incomplete contracting and control rights literature, is advanced to evaluate the successes and failures of a variety of PPP in the natural resources. These case studies provide unique insights into the contract structures that are typically designed for the management and provision of impure public goods. We demonstrate the desired contract structure of a PPP depends on the type of good or service produced, and it is this pivotal point that generally results in shared authority in the extraction or production and consumptive distribution of natural resources.

Governance Structures and Resource Policy Reform: Insights from Agricultural Transition

Abstract: New research on the political economy of policy-induced distortions to incentives for optimal resource use in agriculture and insights from the study of the dramatic reforms in former state-controlled economy has led to enhanced insights on the role of governance structures on policy making in agricultural and natural resources. This paper reviews these research developments and key new insights.

Distortions to Agricultural Versus Nonagricultural Producer Incentives

Abstract: For more than a century, government policies have grossly distorted resource use in agriculture, both within and between countries. Earnings from farming in many developing countries have been depressed by a prourban bias in own-country policies as well as by governments of richer countries favoring their farmers with import barriers and subsidies. Both sets of policies reduce national and global economic welfare and inhibit economic growth; they also add to inequality and poverty in developing countries. Since the 1980s, however, numerous developing and some high-income country governments have reduced their sectoral and trade policy distortions. This paper draws on new empirical studies to show the changing extent of policy distortions to prices faced by the world's farmers since the 1950s. Modeling results provide an indication of how far those reforms proceeded between the early 1980s and 2004 and of how much scope remains for removing continuing inefficiencies in global agricultural resource use.

Rent Taxation for Nonrenewable Resources

Abstract: The literature on taxation of rents from nonrenewable resources uses different theoretical assumptions and methods and a variety of empirical observations to arrive at widely diverging conclusions. Many studies use models and methods that disregard uncertainty, investigating distortionary effects of different taxes on whether, when, and how to explore for, develop, and operate resource deposits. Introducing uncertainty into the analysis opens a range of challenges and leads to results that cast doubt on the relevance of studies that neglect uncertainty. There are, however, several ways to analyze uncertainty regarding companies' behavior, resource price processes, and diversification opportunities, all with different implications for taxation. Methods developed in financial economics since the 1980s, though promising, are still not in widespread use. Additional topics covered in this review are optimal risk sharing between companies and governments, time consistency and fiscal stability, the relationship ...

An Amateur Among Professionals

Abstract: This brief retrospective note describes the author’s occasional contributions to the economics of natural resources. It emphasizes the role and interpretation of the Hotelling condition and discusses the reasons why that result plays so small a role empirically. The concept of sustainability is introduced in the simplest possible content, that of directly consuming a finite stock over infinite time. When the resources flow is an input into production along with capital that can be accumulated, the nature of sustainability changes and becomes more interesting. It is suggested, however, that to consider instead the eventual availability of a resource-free backstop technology may be just as interesting and more relevant. That concept is illustrated in the direct-consumption context but awaits further development in production economies.
