Poverty and pollution abatement: Evidence from lead phase-out

An extensive literature suggests that poverty prevents nations from abating many forms of pollution. Considerable research also proposes a competing claim, that poverty delays but does not prevent pollution abatement. Neither position enjoys persuasive empirical support. Data describing the phase-out of leaded gasoline allow for empirical investigation and they support the latter claim—that poverty delays but does not prevent pollution abatement. Many poor nations have solved the problem of vehicular lead pollution and they have tended to follow rich nations in doing so. The phase-out achievements of richer nations have generated much of the ability and will that has enabled poor countries to solve the problem. The pattern of abatement sequencing and its root causes present important implications for environmental policy and research.     

Changes in the Distribution of Air Pollution Exposure in the Los Angeles Basin from 1990 to 1999

This research assesses changes in the patterns of ozone and particulate concentrations and the associations of these pollutants with socioeconomic factors from 1990 to 1999 in the South Coast Air Basin of California. The results are somewhat different in 1999 than in 1990 and suggest that demographic changes, in concert with changes in emissions and resulting air pollution patterns, determine the pattern of air pollution exposure and how exposure changes over time.

It's an ill wind: The effect of fine particulate air pollution on respiratory hospitalizations

While a growing literature in economics has established the harmful health effects of longstanding criteria air pollutants such as ozone and carbon monoxide, fine particulate air pollution is relatively understudied. This paper provides evidence on the harmful effects of fine particulate pollution for Ontario, where municipalities enjoy particulate levels well below US Environmental Protection Agency (EPA) standards and predominantly below Canada‐wide standards. Results provide strong evidence for the detrimental effect of fine particulate pollution for the respiratory health of children, with a one standard deviation change in particulate pollution, leading to a 4% increase in respiratory admissions. While these results inform the stringency of current pollution standards, they also highlight the importance of an international approach to air quality. For instance, the paper also shows that particulate levels in Ontario municipalities are strongly influenced by southerly winds from US jurisdictions, which adhere to more lenient EPA standards.     

Technical Synergies and Trade-Offs Between Abatement of Global and Local Air Pollution

In this paper, we explore the synergies and tradeoffs between abatement of global and local pollution. We build a unique dataset of Swedish combined heat and power plants with detailed boiler-level data 2001–2009 on not only production and inputs but also on emissions of \(\hbox {CO}_{2}\) and \(\hbox {NO}_{\mathrm{x}}\). Both pollutants are regulated by strict policies in Sweden. \(\hbox {CO}_{2}\) is subject to the European Union Emission Trading Scheme and Swedish carbon taxes; \(\hbox {NO}_{\mathrm{x}}\)—as a precursor of acid rain and eutrophication—is regulated by a heavy fee. Using a quadratic directional output distance function, we characterize changes in technical efficiency as well as patterns of substitutability in response to the policies mentioned. The fact that generating units face a trade-off between the pollutants indicates the need for policy coordination.     

The effects of the external debts of Mexico,Brazil, Argentina,Venezuela, and the Philippines on the United States

The external debts of developing countries have become a major issue recently, prompting debate among both academicians and policy markers. In this paper, the author describes the origins and history of debt problem, summarizes proposals for policies for creditor nations, and estimates the effects of debt-related austerity in five major debtor nations on US imports, exports, net exports, and output in 1985. He concludes that debt-related austerity was responsible for 11.0% of the US merchandise trade deficit in that year, caused decreases in US net trade in 40 to 61 non-service industries studied and decreases in output in 46 industries, and caused a decrease of 0.5% in GNP.

Dose response functions and the harvesting effect

Much of the existing literature on air pollution and mortality deals only with the short-term effects of air pollution. Policy on the other hand needs to know when, whether and to what extent pollution-induced increases in mortality counts are reversed. This involves modelling the entire infinite distributed-lag effect of air pollution on mortality counts.Using an ARMAX modelling strategy this paper illustrates how distributed lag effects can be parsimoniously but plausibly estimated in the context of a time-series study into the relationship between ambient levels of air pollution and daily mortality counts for Manchester. The analysis reveals that maximum 1-h ozone levels are strongly associated with daily mortality counts and that a significant harvesting effect is present. The mortality cost of peak 1-h ozone concentrations for Greater Manchester with a population of 2.6 million is estimated to be £572 million annually. This accounts for the fact that some of the deaths associated with maximum 1-h O₃ concentrations have been advanced only by a short period of time.     

VALUING HEALTH EFFECTS: THE CASE OF OZONE AND FINE PARTICLES IN SOUTHERN CALIFORNIA

This study presents a conservative estimate of the health benefits that would result from attainment of the federal ozone and fine particle (PM_2.5) standards in the South Coast Air Basin of southern California. A three‐stage approach is used that links pollution exposures to adverse health outcomes to economic values. The annual value of the aggregate health benefits approaches $500 million (with a range of $295–$646 million) for ozone and exceeds $21 billion (with a range of $12.85–$34.22 billion) for fine particles. Such results are useful to regulatory agencies and other policy makers when evaluating the merits of various air pollution reduction strategies. (JEL Q51, Q53)     

Technology at the beginning of the 21st century1

We are science and technology heading in the decades ahead? All leading industrial nations have been looking for plausible answers to this question. Government agencies and industry—particularly in Japan and the US—have been carrying out technological studies in recentyears to gather facts and arguments for their research planning. An interdisciplinary working group commissioned by the German Federal Research Minister brought together several R&D programme managing agencies under the auspices of the Karlsruhe-based Fraunhofer Institute for Systas and Innovation Research (ISI) to prepare a futures study of science and technology in the German context.     

Environmental impact of household activity in Spain

The objective of this paper is to analyse the environmental impacts of the Spanish economy by way of water and atmospheric pollution on the basis of a Spanish Accounting Matrix for 1999. Only households were taken as an exogenous account. The pollution measures are estimated for seven categories of pollution: three atmospheric pollutants (CO₂, NO_x and SO_x) and four indicators for water (waste water, nitrogen, metals and biological oxygen demand (BOD)). The environmental data base was obtained from the Spanish Statistical Institute.The analysis reveals that pollution in Spain is closely linked to food production, energy, extractive industries and paper manufacturing. We show that services, taken as a whole, are major polluters, though this is due to the volume of household expenditure they represent rather than their pollution potential as such. We also show that the Spanish economy avoids a great deal of pollution by importing inputs, which pollute where they are produced. Finally, the study also provides per capita pollution values for the aforementioned seven pollutants.     

The effects of air quality regulations on the location decisions of pollution-intensive manufacturing plants

This research examines the effects of the 1977 Clean Air Act Amendments (CAAA) on the location decisions of pollution-intensive manufacturing plants. We develop a panel data set to analyze plant births of polluting manufacturers over time as a function county-level attainment status of the federal standard for ozone pollution. We find that more stringent county-level environmental regulations impact pollution-intensive capital flows through deterring new plant births. We also find that the impact of stricter regulations varies by pollution-intensity of manufacturers, with results suggesting that federal guidelines have a greater impact on high pollution intensive manufacturers than more moderate polluters.      

Tradeable permits,missing markets,and technology

This paper examines the effects of missing markets, heterogeneous pollutants, and the pollution technology of firms on the efficacy of transferable pollution permits. Under the assumption of perfect competition in all markets, we show that if firms can substitute among pollutants, then setting the optimal number of permits for only one pollutant will not, in general, lead to an efficient outcome. The degree of the inefficiency will depend on the information set available to the regulator and the substitutability among pollutants by firms. When establishing transferable pollution rights regulators should, therefore, consider the technology of firms. If firms discharge pollutants in the same fixed proportions, then the regulator need only set a market for one of the pollutants to ensure an efficient outcome. Where firms can substitute among pollutants, however, establishing a market for only one pollutant provides an incentive for firms to substitute to unregulated ones. This is an important policy issue as substitutability among pollutants within and across production processes may dampen the dynamic advantages of a tradeable permit policy.     

Are short‐term effects of pollution important for growth and optimal fiscal policy?

We study optimal fiscal policy in a stock‐flow model of the environment within an endogenous growth framework, where some pollutants have a lasting impact on environmental quality which is restored through abatement expenditure, while others dissipate and hence, have a short‐term effect on the environment. All pollutants, however, affect the productivity of a public good negatively. Given that short‐term pollution, although it dissipates, is irreversible in this sense, a government cannot ignore its negative effects since this type of pollution lowers the productivity of all inputs. We find that a larger negative effect of short‐term pollutants as well as a higher congestion effect of private capital leads to corrective fiscal policies with higher optimal income tax and abatement expenditure rates, which have favorable growth consequences. Interestingly, we find that the rate of short‐term pollution does not affect optimal fiscal policy while that of the long‐term pollution does.     

Using Non Market Valuation to Inform the Choice Between Permits and Fees in Environmental Regulation

The purpose of this short note is to open an exploration regarding the use of non market valuation to help guide the selection of economically efficient pollution control instruments. As long as non market valuation techniques can correctly estimate the slope of the marginal benefit of abatement curve, this information along with engineering cost estimates of the unit costs or slope of the marginal abatement cost will provide useful information to policy makers in choosing between fees and permits. An illustrative review of the literature suggests that both stated and revealed preference methods have estimated slopes of marginal benefit functions for reducing several pollutants. To investigate the efficiency of permits versus fees, an illustrative review of corresponding marginal abatement costs is also made. For air pollutants affecting visibility, the slope of the marginal benefit curve is far greater than the slope of the marginal abatement costs, suggesting permits as the efficient instrument. For nitrates in groundwater used for drinking, the marginal benefit curve is flatter than the rather steep marginal abatement cost, suggesting fees/taxes would be a more efficient economic instrument. We hope this note stimulates more emphasis in non market valuation on estimating the slope of the marginal benefit function to enhance environmental economists ability to make policy recommendations regarding the choice of pollution instruments for specific pollutants.      

Air pollution and the housing market: A neural network approach

Using the neural network method, this research explores the impact of total suspended particulate (TSP) and sulfur dioxide (SO₂), two major air pollutants, and of air pollution controls on the median real price of housing in Jacksonville, Florida. The results of this case study confirm the adverse effect of air pollution on the price of housing. The simulation of the model further suggests that pollution control measures improve property values. The findings imply that, in addition to other measures influencing the price of housing, property owners and buyers take air pollution and pollution controls into account.     

Pollution Control and Foreign Direct Investment in Mexico: An Industry-Level Analysis

Foreign direct investment (FDI) flows into developing countries have been increasing dramatically over the past decade. At the same time, there has been widespread concern that lax environmental standards are in part responsible for this surge. This paper revisits the question of the existence of a pollution haven effect by examining the extent to which the pollution intensity of production helps explain FDI in Mexico. We focus on pollution intensities, which are directly related to emission regulations, rather than unobservable pollution taxes and allow for substitution between capital and pollution. Examining several different pollutants, we find a positive correlation between FDI and pollution that is statistically and economically significant in the case of the highly regulated sulfur dioxide emissions. Industries for which the estimated relationship between FDI and pollution is positive receive up to 30% of total FDI and 30% of manufacturing output. Although we confirm the importance of Mexico’s comparative advantage in labor-intensive production processes, consistent with the previous literature, our results suggest that environmental considerations may matter as well for firms’ investment decisions.      

辽河流域社会经济活动的环境污染压力研究——以氮污染为研究对象

水体中氮含量过高会造成水体富营养化,使水质恶化,破坏水体生态平衡。氮污染已引起人们的普遍关注,国家已将氨氮和氮氧化物列为"十二五"期间环境治理的重要污染指标。辽河流域大部分河段氨氮仍超过V类水质标准,支流水体污染依然十分严重。文章以辽河流域氮污染为研究对象,从农田化肥流失、畜禽养殖、工业生产、居民生活和城市径流五个方面估算了流域氮排放情况。结果表明:辽河流域2010年总氮排放量约13.6万吨,氨氮排放量约6.78万吨,居民生活和畜禽养殖排放合计分别占总氮和氨氮排放量的87%和90%,是流域氮污染的主要贡献方面;工业生产虽产生大量含氮废水,但工业废水和污染物的排放率较低,对环境污染的贡献有限,并不是流域氮污染的主要贡献者;短期内流域氮排放的削减幅度有限,未来一段时期内辽河流域氮污染的压力依然突出;对污染排放环节的技术改造和方式创新是削减流域氮污染高效可行的措施。     

Dynamics of the North-South welfare gap and global sustainability

The vast heterogeneity among nations in terms of economic and demographic characteristics is evident, despite being overlooked in some global studies. In this heterogeneity, it is possible to identify some distinct aggregate classes differing at some very fundamental level: developing (South) nations and developed (North) nations may have very different, asymmetric problems, goals and structures. This study investigates these two distinct groups of socio-economic systems, as they interact in a context of global sustainability. We identify population, economic growth, welfare gap, energy supply and pollution as key issues and analyze them using a systems perspective. A dynamic feedback model, which discriminates the two groups of nations, is constructed to study the dynamics of variables related to the above key issues. The model is tested using extensive data between the years 1980-2005. According to the reference behavior covering the period 1980-2050, it is not viable to close the welfare gap between North and South, given the current prevailing non-renewable-resource-based growth system. A non-renewable-resource-based system adopted by the economic system of growing South would take the global system even closer to its limits. It is observed that indicators like reserve-to-demand ratio fail to provide reliable signals for a timely transition to alternative resources, and a very serious economic recession due to resource scarcity is likely to develop in the next couple of decades. By coupling the demographic and economic dynamics, it is shown that an economic slowdown due to a resource scarcity may have a dramatic widening effect on the already existing welfare gap. Scenario and policy experiments verify the widely accepted importance of stabilizing the population growth in South, transition to alternative energy resources, and investment support to the South in this transition simultaneously in order to reduce the welfare gap between the two blocks. It is observed that enthusiastic targets for an energy transition may have a serious negative impact on the welfare level experienced in South, whereas an energy transition in South supported by North seems to have the most desirable outcome regarding the welfare gap.     

Air Pollution and Sick-leaves

During the last decade an increasing amount of studies have investigatedthe relationship between air pollution and human health effects. In thisstudy we investigate how these effects in turn induce reduced labourproductivity in terms of sick-leaves, which is an important factor inassessment of air pollution costs in urban areas. For this purpose weemploy a logit model along with data on sick-leaves from a large office inOslo and different air pollutants. Our results indicate that sick-leaves aresignificantly associated with particulate matter (PM₁₀), while theassociations with SO₂ and NO₂, are more ambiguous. We also tryto estimate the induced social costs in terms of lost labour productivity andincreased governmental expenditures, although these estimates are moreuncertain.     

Leader of the pack? German monetary dominance in Europe prior to EMU

In this paper, the monetary policy independence of European nations in the years before European Economic and Monetary Union (EMU) is investigated using cointegration techniques. Daily data is used to assess pairwise relationships between individual EMU nations and ‘lead’ nation Germany, to assess the hypothesis that Germany was the dominant European nation prior to EMU. By and large our econometric investigations support this hypothesis, and lead us to conclude that the only European nation to lose monetary policy independence in the light of monetary union was Germany. Our results have important policy implications. Given that the loss of monetary policy independence is generally viewed as the main cost of monetary unification, our findings suggest a reconsideration of the costs and benefits of monetary integration. A country can only lose what it has, and in Europe the countries that joined EMU — spare Germany — apparently did not have much to lose, at least not in terms of monetary independence. Instead, they actually gained monetary policy influence by getting a seat in the ECB's governing council which is responsible for setting interest policy in the euro area.     

POLLUTION PREVENTION AS PUBLIC POLICY: AN ASSESSMENT

In recent years, both the public and private sectors have become increasingly interested in pollution prevention—avoiding creation of pollution—as an alternative to treatment or disposal. Observers cite a number of advantages for this approach, such as eliminating the problem of switching pollution from one medium to another and reducing environmental problems by avoiding pollutants in the first place. This paper assesses the advantages of pollution prevention and contrasts them with a performance standard that restricts pollution but gives businesses maximum discretion in how to meet the restriction. In most situations, a performance standard can be less costly and equally effective. However, pollution prevention may be more desirable in the case of nonpoint source pollution or when a pollutant affects a number of media .
