Cost savings in unit-based pricing of household waste: The case of The Netherlands

We estimate the effects of four unit-based pricing systems on waste collected in Dutch municipalities. Unit-based pricing is shown to be effective in reducing unsorted and compostable waste and in stimulating recyclable waste. If the estimations are corrected for differences in environmental activism between municipalities the effects are still large but significantly lower. The bag- and weight-based systems perform equally and far better compared with the frequency- and volume-based systems. This is interesting, as administrative costs are significantly lower for the bag-based system. Finally, unit-based pricing has no effect on the amounts of waste collected in surrounding municipalities.     

Effects of Unit-Based Garbage Pricing: A Differences-in-Differences Approach

Using a unique 10-year dataset of all 458 Dutch municipalities, we apply a differences-in-differences approach to estimate the effect of unit-based pricing on household waste quantities and recycling. Community-level studies of unit-based pricing typically do not include fixed effects at the local level. We find that failure to do so may substantially inflate the estimated price effect. We also find that unit-based pricing may be endogenous, and use instrumental variables to account for this. Our analysis shows that user fees depend on user fees in neighboring jurisdictions (policy interaction). Our estimate of the garbage reduction per $1 user fee is lower than any previous estimate bar one. The price effect depends on the pricing system: weight-based systems reduce garbage quantities more than volume-based systems. User fees increase recycling, especially of paper, but not nearly as much as they reduce garbage quantities. We find no evidence for waste tourism or illegal dumping.     

An EU Recycling Target: What Does the Dutch Evidence Tell Us?

The European Union (EU) advocates a household waste recycling rate of more than 65 %. Although the Netherlands has already invested heavily in recycling policies, this is still a big challenge as nowadays this rate is approximately 50 % on average and very few no municipalities have a rate above 65 %. Given this practice, it is possible to learn from the Dutch experience which policies are effective in increasing recycling rates. Based on a large panel data set for the Netherlands, we show that unit-based pricing, avoiding a duo-bin for unsorted and compostable waste, and reducing the frequency of collecting unsorted and compostable waste at the curbside are effective in raising the recycling rate. However, only a bag-based pricing system has a substantial effect, but this policy can have some adverse effects. Other unit-based pricing systems have effects of less than 10 % points. In nearly all cases, changing the frequency of collection of recyclables has no or very small effects. Moreover, the complementarity between unit-based pricing and curbside service is low. Overall, it seems very difficult to reach the EU goal of 65 % with the policies applied.     

Does garbage pricing increase the immoral disposal of household waste?

Some empirical studies have attempted to clarify the mechanism of illegal dumping by examining the degree to which per-bag pricing plays a role. However, previous research on the behaviour of avoiding paying a charge for waste collection has tended to neglect so-called ‘immoral disposal,’ which is less risky than illegal dumping because there is no legal penalty. In this study, we define immoral disposal as the dumping of waste in a manner that is immoral but not illegal. To detect the existence of immoral disposal, we apply a spatial econometric approach, namely an extended panel spatial Durbin model, to identify the actual spillover effect of garbage pricing in neighbouring municipalities on immoral disposal from the total waste. A major finding of this study is that immoral disposal exists in unit-based pricing, two-tiered pricing, and fixed pricing.     

Evaluating Unit-Based Pricing of Residential Solid Waste: A Panel Data Analysis

Municipalities introduced unit-based pricing (UBP) with the aim of achieving a decrease in household waste generation and for the replacement of unsorted waste with recycling. Although many studies have shown that UBP has a short-run effect on recycling, few works have tackled the long-run effect on waste generation and recycling. By using panel data for 665 Japanese cities over 8 years, we examine the long-run effect of UBP on waste generation and recycling. The estimation results in waste generation suggest that there is a rebound effect, though a small one. We confirm that the effect of UBP on recycling sustains for the long run. We also find that the short- and long-run responses to an economic incentive for recycling activities differ with income groups. Recycling among the high-income group has not been promoted by implementation of UBP, but people in that group are willing to participate in recycling without an economic incentive. In contrast, recycling activity within the low-income group is strongly motivated by UBP for many years.     

Financing a competitive recycling initiative in Switzerland

The purpose of the paper is to enhance the understanding of different pricing systems within the real world of solid waste management: first the effect on recycling behaviour of citizens, and second the effect on the budget goals, and third the operational logic of different economic measures will be analyzed. Hence it helps practitioners understand and cope with the challenge of meeting the zero profit budget goal in public solid waste management while inducing behaviour change in the regional solid waste system. The question “How can robust recycling strategies be financed?” is addressed.The analysis draws on a system dynamics model for solid waste management that is based on a model framework on human behaviour and public policy that embraces an evolutionary feedback perspective. The model structure was deduced from an ex-post analysis of observed phenomena in solid waste management such as recurring budget deficits at the local level in Switzerland. The paper illustrates how the model was used as a policy lab in which various pricing and incentive strategies were tested that allowed addressing “what-if-questions” under controlled conditions. The various policy-experiments illustrated crucial trade offs between zero profit budget goals at the local level and the administration of a successful recycling initiative. Different scenario-experiments show that under worst-case conditions economic instrument are not sufficient in order to yield a robust policy outcome.     

ASSESSING INCENTIVE-BASED ENVIRONMENTAL POLICIES FOR REDUCING HOUSEHOLD WASTE DISPOSAL

In residential solid waste management, the United States has a great deal of experience in applying incentive-based environmental policy in the form of unit pricing. This study examines the two most common forms of unit pricing practiced in the United States. It offers intuition and empirical evidence suggesting divergence of theoretical expectations and actual outcomes regarding the effects of switching to unit pricing. Data collected from households in Marietta, Ga. during a solid waste pricing experiment serve as the basis for the analysis.     

Adopting a Unit Pricing System for Municipal Solid Waste: Policy and Socio-Economic Determinants

Concerns about the environmental and aesthetic damages of municipal solid waste pollution have triggered policy reform at all levels of government. As part of this effort, public officials are integrating market-based policy instruments such as unit pricing into their solid waste plans. Despite the economic advantages of unit pricing, constituency response has been mixed and hence adoption rates have been below expectations. If the associated gains are to be realized, public officials must identify the key factors that influence this decision. To that end, this research empirically estimates the determinants of unit pricing adoption at the community level of analysis. Based on data for all cities and towns in Massachusetts, the results indicate that demographics, socio-economic attributes, fiscal capacity, and policy instruments influence this decision.     

The effect of regulatory scrutiny: Asymmetric cost pass-through in power wholesale and its end

We find an asymmetric pass-through of European emission allowance (EUA) prices to wholesale electricity prices in Germany and show that this asymmetry disappeared in response to a report on investigations by the competition authority. The asymmetric pricing pattern, however, was not detected at the time of the report, nor had it been part of the investigations. Our results therefore provide evidence for the deterring effect of regulatory monitoring on firms which exhibit non-competitive pricing behavior. We do not find any asymmetric pass-through of EUA prices in recent years. Several robustness checks support our results.     

Analysing the evolution of industrial ecosystems: concepts and application

Industrial ecology and the industrial ecosystem approach (IE) are emerging concepts in ecological economics, environmental policy and corporate environmental management. The natural ecosystem model of diverse recycling and cascading material and energy flow systems has been used in industrial systems that are contrasting to this, operating with linear flows and unsustainable. Understanding the evolution of industrial systems over time toward sustainable or unsustainable ways of operating is important for learning about environmental performance analyses as well as for future planning of policy and management. The evolution over time of the Uimaharju forest industry park in Eastern Finland is studied. First, the system development is described by identifying the number of IE-type ‘roundput’ material and energy flows denoting waste utilisation and sustainable use of renewables. Second, development of the system over time is shown in terms of the number of the actors involved. This structural characteristic is termed system ‘diversity’. Third, the relation of the two is considered. Fourth, the drivers of the case system development are discussed. Fifth, an initial effort is made to calculate some of the environmental effects of the system during its development. An increase in roundput and diversity over time is observed. Diversity is affecting roundput. The park tends to enlarge its activities outside the industrial park boundary over time. While the system illustrates high roundput and high diversity, we can only speculate if these characteristics contribute to sustainability, because of difficulties in system boundary definition.     

Average-cost pricing: Some evidence and implications

We present new survey evidence on pricing behavior for more than 14,000 European firms, and study its macroeconomic implications. Among firms that are price setters, roughly 75% respond that their prices are set as a markup on total costs, a business practice termed “full cost pricing”. Only 25% set prices as markups over variable or marginal costs. Moreover, using industry data for the U.S., we find that the correlation between changes in output prices and changes in variable input prices is significantly lower when fixed costs are likely to be more important.Since our results are similar to the findings in the classic and controversial paper of Hall and Hitch (1939) and subsequent survey evidence, we believe it worth studying the implications of full cost pricing for macroeconomics. We first propose a problem for the firm where full cost pricing can arise as optimizing behavior. We embed this problem, featuring an occasionally binding constraint, into a simple general equilibrium model. We show that when the model is hit by a shock that makes the constraint binding, the response of endogenous variables is amplified significantly more than it would be under the unconstrained regime.     

Environmental productivity and Kuznets curve in India

As a result of India's extremely rapid economic growth, the scale and seriousness of environmental problems are no longer in doubt. Whether pollution abatement technologies are utilized more efficiently is crucial in the analysis of environmental management because it influences the cost of alternative production and pollution abatement technologies. In this study, we use state-level industry data of sulfur dioxide, nitrogen dioxide, and suspended particular matter over the period 1991-2003. Employing recently developed productivity measurement technique, we show that overall environmental productivities decrease over time in India. Furthermore, we analyze the determinants of environmental productivities and find environmental Kuznets curve type relationship existences between environmental productivity and income. Panel analysis results show that the scale effect dominates over the technique effect. Therefore, a combined effect of income on environmental productivity is negative.     

Campaigning for retirement: State teacher union campaign contributions and pension generosity

Since Tullock (1972) first asked why there is so little money in U.S. politics, several studies have found evidence that political activism has the potential to yield significant returns. This study is the first to directly investigate the returns to public sector union activism by leveraging a transactions-level dataset from the National Institute on Money in Politics to estimate the relationship between teachers' union campaign contributions and the generosity of teacher pension systems. Our results show that more politically engaged teachers’ unions, as evidenced by their aggregate campaign contributions, are successful at both securing a higher level of retirement benefits and at shifting a greater burden of the financing of those benefits to the sponsoring government. Our estimates are in line with recent related studies and imply an investment return on campaign contributions of nearly 1500%.     

Waste disclosure and corporate cash holdings

ABSTRACT

In this paper, we address an important and emerging question: Can firms’ voluntary waste disclosure affect corporate cash holdings? Using a sample of S&P 500 firms, we find strong evidence for a positive relationship between waste disclosure and the cash holding policy of firms. Furthermore, we find that waste disclosure significantly increases cash holdings only for firms with strong corporate governance quality. We also find that the significant relationship between waste disclosure and cash holdings remains unchanged only for firms that operate in environmentally sensitive industries. Our paper provides novel evidence on the role of voluntary waste disclosure as an environmental dimension that influences the cash policy of firms and highlights the little-known issue of waste disclosure as a significant research topic.     

Wasting Time? Recycling Incentives in Urban Taiwan and Japan

What makes recycling work? We study the factors driving household waste disposal and recycling in 18 cities in Taiwan and Japan in order to understand the impact of alternative waste management incentives. We show that this depends on the effect of distinct policies on the relative costs of the main alternative disposal methods: recycling, disposal to landfill and illegal dumping. The willingness both to recycle and to dispose to landfill depends on the relative costs of the waste collection regime, and these are dominated by the time cost of alternative disposal methods. The higher the frequency of waste collection, the less recycling and the more disposal to landfill there will be. This is because frequent collection reduces the marginal time-cost of disposal to landfill. Curbside collection of recyclable material, and the frequency of that collection, has a similar effect on the recycling rate. Although direct incentives, such as unit pricing are important in the waste disposal decision, recycling depends primarily on management of the time-costs it involves.     

Volunteer Labour Supply: the role of workers' motivations

Abstract In this paper we study the determinants of volunteering. We depart from previous literature that considers only economic incentives and investigate the role that extrinsic and intrinsic motivations play in shaping the supply of voluntary labour. We build on previous theoretical research and derive a framework for interpreting results from our econometric analysis. We consider a sample of Italian workers of which we can observe proxies of motivations and volunteering choices in three different sectors: social services, political activism and union activism. We make due allowance for the endogeneity of motivations and show that both types of motivations have an effect on volunteering. Consistently with theoretical models, we find extrinsic motivations to lower voluntary labour supply, whereas the opposite holds for intrinsic motivations .     

Resource and Waste Taxation in the Theory of the Firm with Recycling Activities

The management of solid waste has become an urgent problem in nations with a great population density. Accordingly, waste reduction through source reduction and recycling has become increasingly important. Our purpose is to show how prevention, recycling and disposal of waste could be part of a theory of the firm. We first derive efficient production functions from production processes with waste as a by-product. Waste obtained as new scrap can partially be recycled by using additional inputs in order to cut back the purchase of virgin material. Waste not completely recyclable will leave the firm as disposal which also entails cost to the firm. We use the dual cost function approach to develop a theory of the firm under solid residual management.Since the producer does not bear the full cost of disposal, there will be a bias toward virgin materials and away from recycling. The goal of the government is to stimulate the firms to recycle with respect to the preservation of exhaustible resources. An incentive to recycle is a tax on resources or on waste. In order to determine the tax levels the government maximizes welfare subject to the dynamic constraint for decumulation of land fill for waste deposits. This gives the user cost and its time profile for taxing waste disposal or virgin material.In a comparative statics analysis we compare the effect of taxes on waste vs. virgin material on effort to produce in a resource saving manner, on the quantity of recycled material, on output, and on the reduction of waste. Since the impact of environmental regulation on employment is important, our model detects seven effects on labor demand as part of resource conservation policy. We finally carry out a comparative statics analysis of waste intensive firms operating in different market structures. Of interest is the impact of a resource or waste taxation on market volume, on the number of firms, on resource saving effort, and on profit.     

Regulating an Externality-Generating Utility Environmental Taxes Under Limited Information

Global warming is currently an important item on most nationalenvironmental agendas. In many countries, coal-fired electricity generatingstations represent an important source of greenhouse gases. We examinehow regulations to curb emissions affect public utility pricing regulationwhen regulators act non-cooperatively. We show that, when there is limitedinformation on fixed abatement costs, an environmental regulator prefersan emission tax over an output tax or a lump sum environmental tax. Thepublic utility regulator prefers the lump sum tax regime.     

Can consumers enforce environmental regulations? The role of the market in hazardous waste compliance

We examine the U.S. hazardous waste management industry to assess the role that consumers play in encouraging environmental compliance. We first examine whether environmental performance affects consumer demand and find that noncompliance does decrease demand, at least in the short term. Next we consider whether market characteristics affect compliance behavior. While we do not find evidence that market size affects behavior, local competition does appear to increase compliance. However, as competition becomes less localized, it has a smaller effect. Finally, regardless of the pressures exerted by consumers to comply, commercial managers are less likely to be in compliance than on-site managers. For example, President Bush’s 2006 budget request for EPA significantly cut funding to the states who are responsible for over 95% of environmental inspections (ECOS, 2005). At the federal level, the number of positions for compliance monitoring decreased by over 17% from FY 2001 to FY 2003 (U.S. GAO, 2002).     

An environmental assessment of future production-related technological change: 1970–2000 (An input-output approach)

This paper develops a technique, or model, to systematically assess the environmental impact of specific technological changes forecast to occur over this and the next two decades. The core of the model is a dynamic technical coefficient matrix of a large input-output model. The technological change considered is that which affects the coefficients of this matrix and thus the distribution of material inputs over time into the various sectors of the U.S. economy. An environmental assessment of this production-related technological change is achieved through a submodel that registers production residuals on an industry basis for 14 waste categories.
