The merits of different types of regulatory tools in eliminating pollution and at the same time inducing innovation have long been an interest of researchers in both environmental economics and industrial organization. Although there is a substantial theoretical literature investigating the potential for various environmental policies to attain these dual goals, this is a challenging empirical problem because every industry has its own inherent characteristics that play an important role in determining the performance of different regulatory tools. The majority of the work to date focuses on pollution abatement while leaving pollution prevention understudied. In most of the literature firms are also assumed to be symmetric. Asymmetries among firms add another degree and level of complexity to their strategic interactions, and affect the performance of different regulatory tools. This paper investigates the performance of two alternative regulatory tools, an emissions performance standard and an emissions tax, in reducing pollution and inducing pollution prevention and abatement R&D in the US pulp and paper industry. We construct a model representing the industry in an asymmetric Cournot duopoly framework, calibrate the model to disaggregated industry data, and run scenarios to replicate the behavior of the firms in an imperfectly competitive output market. Our results suggest that pollution prevention R&D can respond quite differently than abatement R&D to different policy instruments. The results indicate that R&D spillovers among firms play crucial role in technology development and strategies of the firms. Our results also suggest that strategic interactions between firms in an imperfectly competitive industry can have significant impacts of the levels of both types of R&D. [ABSTRACT FROM AUTHOR]

This paper aims at identifying the causal effect of reducing behavioral costs of participation in household waste recycling through curbside collection. Using propensity score matching and differences-in-differences estimation with individual-level panel data we estimate the effect of curbside collection, its variation between types of recyclables and sociodemographic background variables, and its elasticity with regard to the distance to collection containers in the bring scheme condition. We argue that in a quasi-experimental setting DD may be systematically upward biased due to the outcome variable being self-reported while DDD may be systematically downward biased in the presence of spillover effects. Accordingly, both estimators can be combined to derive upper and lower bounds of the true effect. We find that a curbside scheme has no effect on paper recycling but increases recycling participation by between 10 and 25% points for plastic and packaging. Moreover, we find systematic treatment effect heterogeneity with regard to pre-treatment distance to collection sites and individual environmental attitudes, but not by socio-demography. The results of our analysis therefore have important implications for effective and cost-efficient implementation of environmental protection policies in urban areas. [ABSTRACT FROM AUTHOR]

In this paper, we propose a methodology, based on materials accounting and operational research techniques, to assess different industry configurations according to their life cycle environmental impacts. Rather than evaluating a specific technology, our methodology searchesfor the feasible configuration with the minimum impact. This approach allows us to address some basic policy-relevant questions regardingtechnology choice, investment priorities, industrial structures, andinternational trade patterns. We demonstrate the methodology in the context of the European pulp and paper industry. We are able to show that current environmental policy's focus on maximizing recycling is optimal now, but that modest improvements in primary pulping technology may shift the optimal industry configuration away from recycling toward more primary pulping with incineration. We show that this will have significant implications for the amount and type of environmental damage, for the location of different stages in the production chain, and for trade between European member states. We caution policy makers that their single-minded focus on recycling may foreclose investment in technologies that could prove environmentally superior. Finally, we hint that member state governments may be fashioning their environmental policy positions at least in part on some of the trade andindustrial implications we find. [ABSTRACT FROM AUTHOR]

This paper introduces a special issue devoted to the benefits transfer methods used as part of benefit costs analysis for policy analysis. Benefits transfer methods, as they are applied for environmental policy analyses, use economic concepts together with existing empirical estimates to predict the incremental benefits from a change in some feature of an environmental resource. After giving two examples of the decisions that analysts confront in performing these analyses, I discuss the interconnections between the papers in this issue and the research challenges that emerged from discussions of them.

In this paper we propose a consensus group decision making scheme under model uncertainty consisting of an iterative two-stage procedure based on the concept of Fréchet barycenter. Each stage consists of two steps: the agents first update their position in the opinion metric space adopting a local barycenter characterized by the agents' immediate interactions and then a moderator makes a proposal in terms of a global barycenter, checking for consensus at each stage. In cases of large heterogeneous groups, the procedure can be complemented by an auxiliary initial homogenization stage, consisting of a clustering procedure in opinion space, leading to large homogeneous groups for which the aforementioned procedure will be applied. The scheme is illustrated in examples motivated from environmental economics. [ABSTRACT FROM AUTHOR]

This paper analyses, in the context of the Environmental Kuznet Curve, the determinants of export intensity of hazardous industrial waste among Spanish regions, with particular attention to the influence of waste taxes and of environmental policies. This study is carried out for the first time in the literature with a spatial dynamic model, fixed effects and panel data for the 17 regions (Comunidades Autónomas) of Spain during the period 2007–2017. The results suggest there is a spatial-dynamic component to export intensity, and that both regional taxes on waste disposal and environmental policy stringency appear to encourage, albeit modestly, the rate of exported waste to other regions. The model also shows that the more regions recycle, and the greater the economies of scale arising from industrial agglomeration, the lower is the region's waste export intensity, although increasing restrictions on the international trade in hazardous waste have intensified trading inside the country. Finally, the results suggest a non-linear relationship between growth and export intensity, although apparently we are still far from the absolute decoupling of the Environmental Kuznet Curve.

This paper analyzes information exchange in a model of transnational pollution control in which countries use private information in independently determining their domestic environmental policies. We show that countries may not always have an incentive to exchange their private information. However, for a sufficiently high degree of predictability of domestic environmental policy processes, the expected welfare from sharing information is greater than the expected welfare from keeping it private. The minimum degree of policy predictability for which information sharing occurs increases with the level of environmental risk. Intuitively, information exchange can help mitigate the perception of global uncertainty (both political and scientific) that surrounds transnational environmental problems and potentially improve welfare if policymaking processes are sufficiently aligned with evidence-based approaches (predictable).

This paper assesses the effectiveness of the environmental-related commitments contained in preferential trade agreements (PTAs) on climate change mitigation. A novel and detailed database identifying nearly 300 different types of environmental provisions from more than 680 PTAs since 1947 allows us to distinguish the PTAs with climate-related provisions (PTAwCP) from those with provisions related to other environmental issues. Using panel data covering 165 countries over the period 1995 to 2012, controlling for endogeneity issues, our main result shows that PTAwCP statistically reduce the emissions while the effect of PTAs with provisions related to other environmental issues remains negative but does not significantly affect GHG emissions. Our results suggest that it is rather the specific climate-related provisions in PTAwEP that reduce emissions (carbon dioxide, methane and nitrous oxide). Thus, to be effective in terms of mitigating climate change, PTAwEP should contain climate-related commitments. [ABSTRACT FROM AUTHOR]

The main policy addressing the packaging waste issue in the countries of the European Union has been to define recycling objectives along with Extended Producer Responsibility (EPR). With EPR, producers finance the recycling and management of waste generated by their products. Within this framework, they are expected to internalise waste management costs and engage in eco-design of their packaging, i.e., use less packaging and increase packaging recyclability (e.g., through substitution of materials). EPR has been extended worldwide over recent decades and applied to various waste streams. In this paper, by exploiting temporal variation of an original panel dataset of EPR compliance costs from 25 European countries (1998–2015) and four packaging materials, I evaluate for the first time whether these costs have led to packaging waste reduction and substitution of packaging materials. I find that the EPR financial incentive has resulted in very little (though statistically significant) packaging reduction and no systematic substitution effects between packaging materials.

Environmental and natural resource economics is concerned with questions about how environmental and natural resources are and should be developed and managed. Among the main challenges in this research area is the excessive use of the earth's atmosphere as a sink of greenhouse gas emissions. Anil Markandya is one of the internationally outstanding researchers not only addressing theoretical aspects of environmental problems, but also developing appropriate policy approaches. This paper depicts the milestones of his contributions to environmental economics and gives some special attention to his more recent works. [ABSTRACT FROM AUTHOR]

This paper presents an empirical study of how three waste management policies have affected residential waste generation and recycling behavior in Taiwan over the past decade. The three policies are unit-pricing of garbage in Taipei, a mandatory recycling program in Kaohsiung, and a nationwide policy of charging for plastic bags. We estimate policy effects on total waste, total recycling, and recycling of four specific materials, all measured by weight per capita. Unlike prior work, we find that unit-pricing and mandatory recycling policies lead to significant increases in recycling of most materials, as well as increased levels of total recycling and garbage reduction. The “plastic bag” policy is generally found to lower material-specific and total recycling rates, as well as total garbage volumes. [ABSTRACT FROM AUTHOR]

Protecting human health is a primary goal of environmental policy and economic evaluation of health can help policy-makers judge the relative worth of alternative actions. Economists use two distinct approaches in normatively evaluating health. Whereas environmental economists use benefit-cost analysis supported by monetary valuation in terms of willingness-to-pay, health economists evaluate interventions based on cost-effectiveness or cost-utility analysis (CEA), using quality-adjusted life-years (QALY) or similar indexes. This paper provides background on the controversy about the relative merits of these approaches and introduces the remaining papers in the special issue. These papers (with one exception) were presented at a conference sponsored by the Department of Economics at the University of Central Florida with support from the US Environmental Protection Agency. Although CEA might not lead to substantially different implications for environmental policy than benefit-cost analysis, and QALY may provide a benefit transfer tool to fill gaps in the morbidity valuation literature, the papers in this issue raise serious concerns about the suitability of QALY-based CEA for environmental regulatory analysis. QALY does not in general appropriately represent individual preferences for health and CEA is neither independent of income distribution nor adequate to assess efficiency. [ABSTRACT FROM AUTHOR]

In this paper, we study the formation of international climate coalitions in the case players are perfectly heterogeneous and inequality averse. The paper provides an analytical solution for the optimal contribution of an arbitrary coalition member to a linear and pure public good. Based on empirical estimates for the parameters the model is then applied to the problem of climate mitigation policies. We provide a full stability analysis of all coalitions that can be formed by the twelve world regions from Nordhaus' RICE model. As it turns out, only four two-player coalitions are internally stable. For a wealthy country leaving a coalition, its absolute payoff increases more than its disutility from additional advantageous inequality. A poor country improves its welfare by dropping out since its absolute payoff increases and, at the same time, disutility from disadvantageous inequality is reduced. Introducing suitable transfer schemes, however, large coalitions consisting of economically divergent countries turn out to be internally stable. [ABSTRACT FROM AUTHOR]

In this paper we summarise some of our recent work on consumer behaviour, drawing on recent developments in behavioural economics, particularly linked to sociology as much as psychology, in which consumers are embedded in a social context, so their behaviour is shaped by their interactions with other consumers. For the purpose of this paper we also allow consumption to cause environmental damage. Analysing the social context of consumption naturally lends itself to the use of game theoretic tools. We shall be concerned with two ways in which social interactions affect consumer preferences and behaviour: socially-embedded preferences, where the behaviour of other consumers affect an individual's preferences and hence consumption (we consider two examples: conspicuous consumption and consumption norms) and socially-directed preferences where people display altruistic behaviour. Our aim is to show that building links between sociological and behavioural economic approaches to the study of consumer behaviour can lead to significant and surprising implications for conventional economic analysis and policy prescriptions, especially with respect to environmental policy.

This paper identifies the roles of an environmental protection policy and income growth in enhancing environmental quality in China. In 2005, the Central Government of China piloted a policy that linked regional environmental quality to the performance assessment of local government officials in some provinces. After the implementation of the policy, pollution levels reduced substantially. However, many researchers believe that the improvement of China's environmental quality might have been due to an increase in per capita income, i.e., there is the presence of an "environmental Kuznets curve." We use a nonparametric IV model and a synthetic control method to identify the role of income and policy in improving environmental quality. Results show that after controlling for the mutual effects of the two factors, income level had an inverted U-shaped relationship with sulfur dioxide and wastewater emissions. There are differences in the effects of policies on pollution reduction among different cities, and the magnitude is affected by regional economic development. Our findings contribute to the understanding of the effects of income and policy on pollution reduction. [ABSTRACT FROM AUTHOR]

Increasingly serious air pollution poses a great threat to public health and daily life. Based on the Grossman China health production function, this paper examines the effects of the spatial agglomeration of Chinese public health and the spatial effects of air pollution and other factors on public health considering three aspects. This study employed Chinese macro data on public health and air pollution from 2004 to 2013 to conduct an empirical analysis using a spatial econometrics technique. The main conclusions are as follows. Due to extensive and persistent air pollution, there was a significant spatial agglomeration impact on public health, regional public health presented a convergence effect, and effects of air pollution's negative externalities on public health were significant. Compared with the estimation results obtained when spatial dependence was not considered, the negative effect of the concentration of PM2.5 on public health was higher, implying that the traditional approaches tend to create biases when spatial correlation is ignored; from a regional perspective, the regional differences in the effects of air pollution on public health were significant. Adopting differentiated environmental policies for different regions is the future direction towards which China's environmental governance will develop. [ABSTRACT FROM AUTHOR]

We examine conditions under which a new or tighter restriction on emissions from a competitive polluting industry creates price effects in adjacent markets. Price effects may arise when a quantity restriction on emissions causes output to fall and, therefore, output price to rise. They may also arise when the required reduction in output causes the price of a polluting input to fall. We model emissions as a fixed proportion of output, limiting the possibilities for input substitutions. The possibility of price effects exists whenever the set of regulated firms is large relative to its input or output markets, a possibility that is expressly ruled out in Montgomery's (J Econ Theory 5:395-418, 1972) paper. Two potential implications of price effects are explored. One is an efficiency concern: a welfare-maximizing regulator who neglects price effects will require more than the optimal level of abatement. The other is a distributional concern: an emissions restriction might create windfall profits for the polluting industry. [ABSTRACT FROM AUTHOR]

This paper analyzes the effect of emission permit banking on clean technology investment and abatement under conditions where the stringency of the future cap is uncertain. We examine the problem of heterogeneous firms minimizing the cost of intertemporal emission control in the presence of stochastic future pollution standards and emission permits that are tradable across firms and through time. A firm can invest in clean capital (an improved pollution abatement technology) to reduce its abatement cost. We consider two possibilities: that investment is reversible or irreversible. Uncertainty is captured within a two period model: only the current period cap is known. We show that if banking is positive and marginal abatement costs are sufficiently convex, there will be more abatement and investment in clean technology under uncertainty than there would be under certainty and no banking. These results are at odds with the common belief that uncertainty on future environmental policy is a barrier to investment in clean capital. Moreover, under uncertainty and irreversibility, we find that there are cases where banking enables firms to invest more in clean capital. [ABSTRACT FROM AUTHOR]

This article presents an editorial on the contributions of David W. Pearce to environmental economics and policy. Pearce's impact in Europe was formidable as he changed the term "environmental economist" from an oxymoron to a job description increasingly valued by governments. Pearce is known for his ability to take difficult subjects and make them clear and accessible for decision makers. Many of Pearce's accomplishments are outlined.

This paper investigates empirically the determinants of household recycling in Norway and compares the results with a similar, recently published, study of households in the United States. The comparison focuses on the relative importance of user fees on waste disposal, community recycling programs, and socioeconomic factors. Both data sources are nationwide, material-specific, and at the household level. One major finding is that a disposal fee provides a significant economic incentive to Norwegian households, whereas its effectiveness in the United States is still up for debate. Providing households with convenient recycling options, such as curbside and drop-off recycling, appears generally effective, but less so in Norway than in the United States. Socioeconomic characteristics are less important predictors of behavior in Norway than in the United States. Qualifications on the comparison are provided throughout and two extensions for future research are suggested at the end. [ABSTRACT FROM AUTHOR]

This paper examines the effect of environmental regulation on a firm’s incentives to invest in developing cheaper (clean-up) technologies in a model where consumers are willing to pay for environmentally clean technologies. It focuses on two types of policies: a BAT based policy and a commitment policy. In the former policy, the standard is based on the best available technology (BAT) where the regulator re-optimizes environmental regulation in response to new technologies. However, under a commitment policy, the regulator announces a regulation and sticks to it irrespective of the firm’s adopted technology. The paper finds that cleaner technologies are not adopted if the regulator announces a BAT based policy. A commitment policy not only leads to positive investment in research and development but is also welfare improving. [ABSTRACT FROM AUTHOR]

Strict environmental regulation may deter foreign direct investment (FDI). The paper develops the hypothesis that regulation predominantly discourages FDI that is conducted as Greenfield investment rather than mergers and acquisitions (M&A). The hypothesis is tested with German firm-level FDI data. Empirically, stricter regulation reduces new Greenfield projects in polluting industries, but indeed has a much smaller impact on the number of M&As. This significant difference is compatible with the fact that existing operations often benefit from grandfathering rules, which provide softer regulation for pre-exisiting plants, and with the expectation that for M&As part of the regulation is capitalized in the purchase price. The heterogeneous effects help explaining mixed results in previous studies that have neglected the mode of entry. [ABSTRACT FROM AUTHOR]

The paper empirically investigates whether developing countries may use trade policy as an alternative to environmental policies in order to control carbon emission. It measures the effectiveness of the existing 'Most Favored Nations' (MFN) tariff rates applicable to lower-middle income countries and for countries sorted on the basis of manufacturing-to-trade shares, in lowering carbon emission. By applying a fixed effects panel regression method over 16 years, it is found that the MFN tariff rate helps these economies to reduce carbon emission substantially. In addition, the role of foreign direct investment as purveyor of clean products is explored at the cross-country level. The results, at least on the ground of better environmental standards, indicate the need to re-evaluate the choice for protection under the domain of multilateral trade negotiations.

The strategic roles of adaptation and technological investment in international climate politics have been analyzed within various approaches. What makes this paper unique is that we investigate the combined impact of adaptation and investment on global mitigation and we compare the subgame-perfect equilibria for different sequences of decisions. Considering a purely non-cooperative, game-theoretic framework, we find that by investment countries commit to lower national contributions to the global public good of mitigation. Moreover, the order of adaptation before mitigation might reinforce this strategic effect of technological investments. As a consequence, the subgame-perfect equilibrium for symmetric countries yields a globally lower level of mitigation, and higher global costs of climate change when countries engage in advanced adaptation. Besides this theoretical contribution, the paper proposes some strategies to combat the unfortunate 'rush to adaptation' which can be currently observed in climate politics. [ABSTRACT FROM AUTHOR]

Typical convergent validity tests of benefit transfer based on stated preference data assume that willingness to pay (WTP) estimates have been accurately measured, and that differences in WTP arise from differences in observable and unobservable characteristics between the study and the policy sites. In this paper, we conduct a convergent validity test assuming equality of underlying preferences, but allow for the possibility that transfer errors arise from differences in the way that respondents process information in the preference elicitation tasks. Using data from an identical survey instrument applied to the population of two river basins in Spain, we obtain marginal and total WTP estimates for ecological improvements of water bodies and the corresponding transfer errors across sites. Results of equality constrained latent class (ECLC) models that infer attribute non-attendance (AN-A) are compared to results from mixed logit (MXL) models in WTP space. We find large absolute and relative differences in marginal and total WTP between sites for the MXL models, and significantly reduced transfer errors for the ECLC models. This paper therefore provides further evidence that AN-A can significantly affect environmental values derived from attribute-based stated preference methods and is the first to investigate the implications for benefit transfer.

The literature that analyzes the coordination of environmental taxes by governments considers that firms produce a single good at a single plant. However, in practice firms tend to produce several goods at various production plants (multiproduct firms). These firms may organize themselves in a centralized or decentralized fashion for purposes of decision-making: This affects their output and pollution levels. This paper sets out to analyze the coordination of environmental taxes considering multiproduct firms. We find that the organizational structure chosen by the owners of the firms depends on whether or not governments coordinate with one another in setting taxes, and on whether the goods produced are substitutes or complements. Social welfare is greater if a supranational authority sets taxes in all countries. In this case, joint welfare is never lower if the authority is constrained to set the same tax in all countries.

The cost and time required to produce original benefit estimates makes benefit transfers a highly valuable component of the process of assessing the benefits and costs of environmental improvements. Because of the great variety of benefit estimates, conducted at different times with different data sources and different techniques, there is concerted effort to understand the validity of transfers. The research in this paper approaches the validity issue of benefit transfers by asking whether there is indirect evidence of the benefits. The premise of the paper is that policies that give significant benefits should induce expected and unexpected behavioral changes. We look for evidence of potential indirect evidence by by estimating the effect of differences air pollutants on activities such as outdoor recreation and work, as found in the American Time Use Survey.

Analysts often extrapolate estimates of the value of environmental improvements reported in prior studies to evaluate new policy proposals, a practice sometimes referred to as “benefit transfer.” Benefit transfer functions are frequently specified based on statistical considerations alone. However, such a purely statistical approach can lead to willingness-to-pay functions that fail to satisfy some aspects of theoretical consistency that may be especially important for policy evaluations. In this paper, we examine several previous meta-analyses of nonmarket valuation studies in light of the adding-up condition, which is one important aspect of theoretical validity. We then use meta-regression to estimate a new willingness-to-pay function for surface water quality improvements intended to be used for benefit transfers. We estimate the meta-regression model using summary results from 51 previously published stated preference studies. An important feature of our approach is that we develop the meta-regression estimating equation to ensure that the resulting benefit transfer function will necessarily comply with the adding-up condition. This is achieved by first specifying a marginal willingness-to-pay function and then deriving an expression for total willingness-to-pay. This leads to a non-linear estimating equation, so we estimate the parameters of the model using non-linear least squares. We discuss the advantages and disadvantages of our approach relative to other structural approaches, and we compare our empirical results to a more traditional nonstructural meta-regression model. Finally, we examine the quantitative importance of imposing the adding-up condition in our case study by performing some illustrative calculations of willingness-to-pay for hypothetical water quality improvements using both structural and non-structural models.

In this paper, we develop a microeconomic approach to deduce greenhouse gas abatement cost curves of the residential heating sector. Our research is based on a system dynamics microsimulation of private households' investment decisions for heating systems to the year 2030. By accounting for household-specific characteristics, we investigate the welfare costs of different abatement policies in terms of the compensating variation and the excess burden. We investigate two policies: (i) a carbon tax and (ii) subsidies on heating system investments. We deduce abatement cost curves for both policies by simulating welfare costs and greenhouse gas emissions to the year 2030. We find that (i) welfare-based abatement costs are generally higher than pure technical equipment costs; (ii) given utility maximizing households a carbon tax is the most welfare-efficient policy and; (iii) if households are not utility maximizing, a subsidy on investments may have lower marginal greenhouse gas abatement costs than a carbon tax.

Stringent environmental regulations may encourage industrial innovation, as technological advancements lower the cost of pollution abatement (Popp et al. in Handbook of the economics of innovation, vol II. Academic Press, Burlington, pp 873-938, 2010). The pollution-havens hypothesis, on the other hand, indicates that, rather than innovating, dirty industries may relocate to countries with less stringent environmental regulations (Copeland and Taylor in J Econ Lit 42(1):7-71, 2004). Thus, more stringent environmental regulations may increase or decrease innovative activities. This paper examines empirically the impact of environmental regulations on R&D intensities and R&D expenditures in 21 manufacturing industries in 28 OECD countries from 2000 to 2007. I consider pollution intensity and the relative ease of relocation (immobility) as industry characteristics that determine the optimal industry response to increased environmental policy stringency. I find that more pollution intensive industries innovate less as regulatory environments become more restrictive relative to less pollution intensive industries. At the same time, more immobile industries innovate more than more mobile industries as environmental regulations become more stringent, illustrating innovation as an alternative to relocation.

This paper presents a distributional argument for the use of supply-side climate policies whereby carbon emissions are controlled through (i) depletion quotas or (ii) permanent confiscation of a fraction of the in situ carbon stocks. The modeling considers intertemporal competitive equilibria in the Cobb-Douglas version of the Dasgupta-Heal-Solow-Stiglitz model of capital accumulation and costless resource extraction. It is shown how policies (i) and (ii) preserve the functional distribution of income between capital owners and resource owners, compared to the case where no climate policy is needed, while suggested demand-side policies do not. Such observations are of interest as avoiding functional redistribution may facilitate climate change negotiations. The paper discusses policy implications of the analysis outside the simplified setting of the stylized model. [ABSTRACT FROM AUTHOR]

This paper examines how income-induced environmental policy differences and damage heterogeneity interact to determine the comparative advantage in a polluting activity. In a non-cooperative framework, North and South regulate two types of pollution, local pollution (e.g., air and water pollution) and global pollution (e.g., greenhouse gas emissions), each of which induces heterogeneous damages for consumers. I find that (1) North or South can have the comparative advantage in the dirty sector; (2) whatever the region with this comparative advantage, the worldwide level of global pollution can either increase or decrease with trade; (3) local and global emissions evolve symmetrically in each region with trade, even though pollution regulations may be asymmetric.

This paper examines household preferences for community recycling programs, which have both public and private good dimensions. The data come from a survey conducted in Seattle (WA) which elicited stated preference-contingent ratings for different recycling programs relative to status quo, with experimental variation in the overall community recycling rate achieved and expected household cost. The recycling rate is interpreted as capturing the public benefits of recycling programs and constitutes the most common measure used by policy agencies for setting waste management objectives and evaluating policy initiatives. The analysis begins with fixed parameter models that explore different ways of handling rating data and mixed logit estimations that capture household preference heterogeneity both within and across different recycling programs. This analysis yields unique estimates of willingness to pay for an increase in the community recycling rate. Predicted individual-specific utility parameters are then regressed on household background information to explicitly examine the nature of preference heterogeneity. Overall, this paper generates interpretable policy-relevant insights into the public and private good dimensions of community recycling programs. [ABSTRACT FROM AUTHOR]

One of the most pressing policy challenges facing the world today concerns how to mitigate global warming while improving people's well-being. The green paradox argues that increasing taxes on CO emissions exacerbates global warming in the present because firms have the incentive to bring forward the extraction and sale of fossil fuels. This paper shows that whenever technological progress allows the extraction costs of fossil fuels to be reduced over time and a positive R&D subsidy is paid, a growing tax on CO emissions reveals a welfare maximizing policy.

I consider a problem in environmental policy design in which I focus on stock pollutants. In particular, I consider stock pollutants that cause severe damage on the environment and do not depreciate at all once they are released into the atmosphere and the ocean. The purposes of this paper are: (1) to provide an economic foundation for environmental policies based on the precautionary principle and the 1992 Rio Declaration on Environment and Development, and (2) to show that this optimal timing rule has a reservation property. Furthermore, I analyze the effect of an increase in ambiguity on the optimal timing of adopting some environmental policy, and show that an increase in ambiguity decreases the optimal timing of adopting the environmental policy.

This paper reviews some recent research in “behavioural economics” with an application to environmental issues. Empirical results from behavioural economics provide a reminder that human behaviour is context-dependent, implying that policy may go awry if based upon models of behaviour which are inappropriate to the contexts in which decisions are made. Recognizing that agents may, in some contexts, systematically make mistakes raises challenging questions about the role of “paternalism” in government policy. The paper considers the research into hyperbolic discounting, and examines the implications for environmental policy. We develop a model of resource management under hyperbolic discounting, which shows that if a planner is unable to commit to a policy, the temptation to re-evaluate the policy in future could lead to an inadvertent collapse in the stocks of a natural resource.

The European Treaty supports the application of the polluter pays principle in all environmental policies including the Water Framework Directive. This paper assesses the efficiency of water-charging systems in two European regions. The regions examined are the South west region of Ireland and the Navarre region in Spain which were selected because they are similar in terms of economic indicators but different in terms of water pricing structures. The paper describes the development and application of a simple model to analyse data on water-charging systems from these two regions. We present the results of a detailed scenario-based investigation illustrating the differences between experience, composition and basis, impact and constraints on the application of water charges for both regions. The key findings are that existing water charges do not provide incentives for users to use water efficiently and thereby do not contribute effectively to the environmental objectives of the Water Framework Directive.

This paper develops a new estimation model for consistent estimation of mean WTP (willingness to pay) in dichotomous choice CV (contingent valuation). Consistent estimation of mean WTP in parametric models requires the correct specification of the probability distribution of WTP. However, it is not possible to foresee the probability distribution, and thus in practical applications there is always a danger of specification error, making it impossible to guarantee that mean WTP will be consistently estimated. This paper applies linear projection to develop an estimation model that enables consistent estimation of mean WTP without specification of the probability distribution. This linear projection model enables us to estimate mean WTP only by calculating a weighted mean of the indicator function defined as 1 (or 0) when a respondent says “yes” (or “no”) for a certain improvement in environmental quality. Moreover, when bids follow the uniform distribution, calculation is possible by multiplying “maximum bid” and “the rate of answering yes”. Therefore, a distinguishing feature of this model is that estimation can be accomplished very easily. [ABSTRACT FROM AUTHOR]

This paper investigates if narratives varying the cause of the COVID-19 pandemic affects pro-wildlife conservation outcomes. In a pre-registered online experiment (N = 1081), we randomly allocated subjects to either a control group or to one of three narrative treatment groups, each presenting a different likely cause of the COVID-19 outbreak: an animal cause; an animal and human cause (AHC); and an animal, human or lab cause. We found that the AHC narrative elicited significantly greater pro-conservation policy support, especially for bans in the commercial trade of wildlife, when compared to the control group. Possible mechanisms driving this effect are that AHC narratives were less familiar, elicited higher mental and emotional engagement, and induced feelings that firms and governments are responsible for mitigating wildlife extinction.

We analyse the welfare effects of environmental policy arising from the formation of an international environmental agreement on the participating and non-participating countries and thus shed light on the potential incentives for a country to join such an agreement. Within a N-country Q-goods general equilibrium framework under free-trade conditions, we consider unilateral and cooperative policy settings and, within the latter, country-specific and fully harmonized policies within the agreement. A key result of the paper is the emergence of a negative relationship, arising from terms of trade effects, between the welfare changes of the participating and non-participating countries following the formation of the agreement. These however do not result in a zero sum welfare outcome for the world as a whole. [ABSTRACT FROM AUTHOR]

The paper examines the effect of freer North–South trade in goods on pollution, commodity terms-of-trade and national welfare, utilizing a factor endowment framework. North and South are distinguished in terms of the relative endowment of a pollution causing natural resource: South is relatively more resource abundant. Compared to the analysis of Copeland and Taylor (1994)—which is the central work so far on this subject—this paper internalizes the commodity terms-of-trade impact of individual environment policies. It is derived that if countries specialize completely in the free-trade equilibrium, both are induced to reduce their pollution as compared to autarky. It is interesting and paradoxical that the South also reduces its pollution, despite specializing in the pollution-intensive good. Again, contrary to common perception, free trade may entail an overall terms-of-trade loss for the North, while South will always have a positive change in the terms-of-trade. Finally, inspite of better environment, free trade may cause both the countries to gain or lose in terms of aggregate welfare. [ABSTRACT FROM AUTHOR]

The paper analyzes how to comply with an emission constraint, which restricts the use of an established energy technique, given the two options to save energy and to invest in two alternative energy techniques. These techniques differ in their deterioration rates and the investment lags of the corresponding capital stocks. Thus, the paper takes a medium-term perspective on climate change mitigation, where the time horizon is too short for technological change to occur, but long enough for capital stocks to accumulate and deteriorate. It is shown that, in general, only one of the two alternative techniques prevails in the stationary state, although, both techniques might be utilized during the transition phase. Hence, while in a static economy only one technique is efficient, this is not necessarily true in a dynamic economy. [ABSTRACT FROM AUTHOR]

We examine two alternative strategies that an environmental group can embark when interacting with a firm. The first one which is already discussed in the literature is when the group campaigns against the firm. The second one which has not been modelled in the literature is when the group collaborates with the firm (green alliance) to reduce the cost of the cleaner technology. We look at the case of both options being available for the group in a setting with an environmental tax. One of the main results of the paper argues that for higher taxation the conflict scenario is more likely to happen, implying that collaboration and a more stringent environmental policy are substitutes. This identifies a previously unexamined and possibly adverse effect of public policy on environmental quality because it weakens the impact of the pollution tax on emission intensity. We also characterise the optimal tax that maximises social welfare and find that under pure conflict –when conflict is the only option for the environmentalists– optimal tax is higher than when the group can choose to act against or join forces with the firm, indicating that a less stringent environmental policy is needed in the latter scenario.

This paper investigates whether environmental or energy-efficiency regulations induce innovations in relevant technologies through focusing on the tightening of Japanese fuel economy regulations in the 1990s and the early 2000s. Unlike previous studies that analyze patent data, I use vehicle-level specification data for 1985–2004 to estimate whether regulatory pressure accelerated technological progress in fuel efficiency. I compare Japanese automakers with selected American and European automakers in a difference-in-differences framework. The estimation results provide strong evidence for induced technological change: conditional on other vehicle attributes and the production cost, the regulatory tightening induced at least a 3–5% improvement in the average Japanese vehicle's fuel economy relative to a counterfactual case with no regulatory change, an effect which would have taken at least 4–7 years to be realized with no pressure from fuel economy regulations or fuel prices.

The aim of this paper is to analyse potential drivers of land use policy, in the form of building permits issued in Italian provinces. We first derive testable implications on the basis of a standard political agency framework, augmented to account for the impact of past environmental disasters (floods, landslides and earthquakes) and for the relevance of "building permits intensive" sectors in determining voters' support to an incumbent politician. We then perform an empirical analysis that tests theoretical predictions using a unique dataset covering Italy in the period 2001–2012. Our main conclusions show that the occurrence of floods and earthquakes decreases building permits, implying that a bad history in terms of these phenomena strengthens the importance of voters affected by past disasters. No corresponding evidence seems to emerge with reference to landslides. On the other hand, the relevance of the construction sector increases the number of building permits issued. Finally, when elections approach, the number of building permits issued grows, suggesting that incumbent politicians may distort land use policies in order to favour "brown" voters in periods close to elections.

This paper analyses the optimal division of environmental policymaking functions among the different levels of government. Using fiscal federalism theory, we identify the most appropriate level of decentralization in each case. The paper focuses on water resources policies, with an application to Spanish regions during the 1996–2001 period. A simulation allows the implementation of more efficient policies in the context of water resources. The results of the empirical exercise show that a decentralized scenario is preferred under strong differences among preferences. [ABSTRACT FROM AUTHOR]

This paper addresses the following question: To achieve a fixed aggregate emissions target cost-effectively, should emissions trading programs be designed and implemented to achieve full compliance, or does allowing a certain amount of noncompliance reduce the costs of reaching the emissions target? The total costs of achieving the target consist of aggregate abatement costs, monitoring costs, and the expected costs of collecting penalties from noncompliant firms. Under common assumptions, I show that allowing noncompliance is cost-effective only if violations are enforced with an increasing marginal penalty. However, one can design a policy that induces full compliance with a constant marginal penalty that meets the aggregate emissions target with lower expected costs. This last result does not depend on setting an arbitrarily high constant marginal penalty. In fact, the marginal penalty need not be higher than the equilibrium marginal penalty under the policy with the increasing marginal penalty, and can actually be lower. Finally, tying the marginal penalty directly to the permit price allows the policy objective to be achieved without any knowledge of firms’ abatement costs. [ABSTRACT FROM AUTHOR]

A number of recent papers in environmental economics have focused on the process of researching preferences – agents are uncertain about preferences but with effort may narrow their uncertainty. This issue has arisen in formulating bids in contingent valuation (CV) as well as the debate over the divergence between WTP and WTA. In the context of CV, it has been suggested that the hypothetical nature of the preference elicitation process biases responses. This paper provides both a theoretical model and experimental evidence to contribute to this debate. The model is a model of competitive bidding for a private good with two components that are particularly relevant to the debate. The first component is that bidders are unsure of their own value for the private good but may purchase information about their own value (researching preferences). The second component is that there is a probability that the auction is hypothetical – that the winning bidder will not get the private good and will not pay the winning bid. The experiment tests this theoretical model of bidding equilibrium and analyzes the effects of variations in the parameters (hypotheticalness, information costs and number of agents) on the endogenous variables (such as the proportion of bidders who become informed and the winning bid). Experimental results suggest that an increase in the hypotheticalness of an auction tends to decrease the likelihood that bidders pay for information on their valuation with an ambiguous effect on the winning bid.

There are a number of features of climate change which make it one of the most challenging problems confronting policy makers and policy analysts. In this paper we consider three such features: (i) climate change is a global pollutant so there are strategic interactions between governments over climate policy; (ii) cutting greenhouse gas emissions can have significant cost effects across a number of sectors of the economy, raising concerns about the implications of climate change policy on competitive advantage; (iii) the long-time scales on which climate change operates means that an important dimension of climate change policy is policy towards R&D to cut the costs of dealing with climate change. In Ulph and Ulph (1996) [Ulph A, Ulph D (1996) In: Carraro C, Katsoulacos Y, Xepapadeas A (eds) Environmental policy and market structure. Kluwer, Dordrecht, pp 181–208] we presented a model to analyse these issues, but considered only environmental policies. In this paper we extend that analysis to allow for both a richer set of policy instruments (environmental and technology policies) and a richer strategic context. [ABSTRACT FROM AUTHOR]
