Offsetting with Salinity Credits: An Alternative to Irrigation Zoning 31
Spencer, Thomas; Ancev, Tihomir.
Irrigation induced salinity is a serious problem in many countries around the world. In Australia, this type of salinity is most pronounced in the valley of the River Murray in South Australia. Location of irrigation enterprises has been identified as a key factor that needs to be taken into account by policies aimed at mitigating salinity. This article compares and contrasts two such policies: an irrigation zoning policy, where new irrigation enterprises are only allowed in low salinity impact zones, and an offsetting with salinity credits policy, where new irrigation enterprises can locate in high salinity impact zones, provided they offset their salinity impact with salinity credits. Key findings are that the offsetting policy will be both less costly...

Determinants of Romanian Farmers' Participation in Agri-Environmental Programmes 31
Toma, Luiza; Mathijs, Erik.
The paper aims to identify the factors underlying farmers' propensity to participate in agri-environmental programmes in a Romanian rural region that confronts non-point source pollution. For this, we employ structural equation modelling with latent variables using data collected through an agri-environmental farm survey in 2001. The model includes one 'behavioural intention' latent variable ('propensity to participate in agri-environmental programmes') and five 'attitude' and 'socioeconomic' latent variables ('demo-social characteristics', 'economic characteristics', 'agri-environmental information access', 'environmental risk perception' and 'general environmental concern'). The results indicate 'environmental risk perception' as the strongest...

Reformulating Competition? Gasoline Content Regulation and Wholesale Gasoline Prices 31
Brown, Jennifer; Mansur, Erin T.; Hastings, Justine; Villas-Boas, Sofia Berto.
The 1990 Clean Air Act Amendments stipulated gasoline content requirements for metropolitan areas with air pollution levels above predetermined federal thresholds. The legislation led to exogenous changes in the type of gasoline required for sale across U.S. metropolitan areas. This paper uses a panel of detailed wholesale gasoline price data to estimate the effect of gasoline content regulation on wholesale prices and price volatility. In addition, we investigate the extent to which the estimated price effects are driven by changes in the number of suppliers versus geographic segmentation resulting from regulation. We find that prices in regulated metropolitan areas increase significantly, relative to a control group, by an average of 3.6 cents per...

A Spatiotemporal Fixed Effects Estimation of U.S. State-Level Carbon Dioxide Emissions 31
Burnett, J. Wesley; Bergstrom, John C..
One of the major shortcommings of past environmental Kuznets curve (EKC) studies is that the spatiotemporal aspects within the data have largely been ignored. By ignoring the spatial aspect of pollution emissions past estimates of the EKC implicitly assume that a region’s emissions are unaffected by events in neighboring regions (i.e., assume there are no transboundary pollution emissions between neighbors). By ignoring the spatial aspects within the data several past estimates of the EKC could have generated biased or inconsistent regression results. By ignoring the temporal aspect within the data several past estimates of the EKC could have generated spurious regression results or misspecified t and F statistics. To address this potential...

Residential Water Consumption: A Cross Country Analysis 31
Grafton, R. Quentin; Kompas, Tom; To, Hang; Ward, Michael B..
Survey data from over 1,600 households in ten countries were used to analyse the determinants of residential water demand. Results show that in every country the price elasticity is negative and statistically significant. Households that do not have to pay for the water they use (volumetric water charges) consume about a third more water than similar households that do have to pay such charges. Consumers’ attitudes do not have a statistically significant effect on total water use, although they do increase the probability of households using some water saving behaviours. Volumetric water charges also have an impact on the adoption of water saving actions. Full-cost water pricing appears to be a highly effective instrument to manage residential water...

Technology Diffusion, Abatement Cost, and Transboundary Pollution 31
Heal, Geoffrey; Tarui, Nori.
This paper studies countries’ incentives to develop advanced pollution abatement technology when technology may spillover across countries and pollution abatement is a global public good. We are motivated in part by the problem of global warming: a solution to this involves providing a global public good, and will surely require the development and implementation of new technologies. We show that at the Nash equilibrium of a simultaneous-move game with R&D investment and emission abatement, whether the free rider effect prevails and under-investment and excess emissions occur depends on the degree of technology spillovers and the effect of R&D on the marginal abatement costs. There are cases in which, contrary to conventional wisdom, Nash...

The Impact of Protest Responses in Choice Experiments 31
Barrio, Melina; Loureiro, Maria L..
Not much attention has been given to protest responses in choice experiments (CE). Using follow-up statements, we are able to identify protest responses and compute welfare estimates with and without the inclusion of such protest responses. We conclude that protest responses are fairly common in CE, and their analysis affects the statistical performance of the empirical models. In particular, when the sample is corrected by protests, our results come from utility consistent models. Thus, future choice experiments should consider the role of protest responses as contingent valuation studies have done.

Distributing pollution rights in cap-and-trade programs: are outcomes independent of allocation? 31
Fowlie, Meredith; Perloff, Jeffrey M..
According to the Coase theorem, if property rights to pollute are clearly established and emissions permit markets nearly eliminate transaction costs, the permit market equilibrium will be independent of how the permits are initially distributed among …firms. Testing the independence of …firms' permit allocations and emissions is difficult because of endogeneity and omitted variable bias. We exploit the random assignment of …firms to different permit allocation cycles in Southern California's RECLAIM Program to test for a causal relationship between facility-level emissions and initial permit allocations. Our primary …finding is that a null hypothesis of zero effect cannot be rejected.

The Potential for Wind Energy Meeting Electricity Needs on Vancouver Island 31
Prescott, Ryan; van Kooten, G. Cornelis; Zhu, Hui.
In this paper, an in-depth analysis of power supply and demand on Vancouver Island is used to provide information about the optimal allocation of power across ‘generating’ sources and to investigate the economics of wind generation and penetrability into the Island grid. The methodology developed can be extended to a region much larger than Vancouver Island. Results from the model indicate that Vancouver Island could experience blackouts in the near future unless greater name-plate capacity is developed. While wind-generated energy has the ability to contribute to the Island’s power needs, the problem with wind power is its intermittency. The results indicate that wind power may not be able to prevent shortfalls, regardless of the overall name-plate...

Consumption and Precautionary Saving: An Empirical Analysis under Both Financial and Environmental Risks 31
Baiardi, Donatella; Manera, Matteo; Menegatti, Mario.
This paper studies the empirical relationship between consumption and saving under two different sources of uncertainty: financial risk and environmental risk. The analysis is carried out using time series data for six advanced economies in the period 1965-2007. The results support the theoretical conclusions that both financial risk alone and the interaction between financial and environmental risks affect consumption. Moreover, we suggest a solution to some shortcomings which concern the empirical analysis performed with one-argument utility functions. Finally, we provide new estimates of indexes of relative risk aversion and relative prudence, and relative preference of environmental quality.

A Multifunctional Comparison of Conventional versus Alternative Olive Systems in Spain by Using AHP 31
Parra-Lopez, Carlos; Calatrava-Requena, Javier.
Sustainability of agriculture is strongly related to the multifunctional role implicitly or explicitly recognized to it in the framework of the European Union CAP. This multifunctional role entails a multicriteria approach when assessing the performance and value for society of farming systems. Multicriteria assessment of agricultural systems is characterized by the existence of many criteria often conflicting among then, many stakeholders and decision-makers with competing interests, and lack of information. Analytic Hierarchy Process (AHP) is a multicriteria methodology that allows dealing with these problems, in a relatively easy, flexible and economical manner, and therefore it is a potentially useful tool in this field, although its application with...

In or Out: Efficient inclusion of installations in an Emissions Trading Scheme? 31
Betz, Regina; Sanderson, Todd; Ancev, Tihomir.
Regulators around the world are currently considering national emissions trading systems (ETS) as a cost-effective way to reduce greenhouse gas emissions. ETS installations coverage is one of the numerous design issues confronting them. ‘Blanket coverage’ that includes all an economy’s industrial emitters of greenhouse gases has some intuitive appeal. Although it seems equitable it does not, however, take into full account all the costs related to the extent of coverage. This report shows how an alternative approach of ‘efficient coverage’ can achieve the same emission reduction outcome at lower social cost. The approach is based on maximising the benefits of including installations in an ETS, while at the same time taking into account all relevant...

Influencia social y sostenibilidad en el uso de recursos renovables 31
Almudi, Isabel; Choliz, Julio Sanchez.
En este trabajo presentamos un modelo en el que las actividades extractivas referidas a un recurso natural renovable, si son abusivas, generan algún tipo de reacción social que modifica las preferencias sociales. Esta modificación es tenida en cuenta por el planificador a la hora de decidir cual es la asignación intertemporal óptima entre consumo y stock del recurso. Bajo estas nuevas condiciones, nos preguntamos cómo cambia el stock del recurso natural en el estado estacionario y qué puede decirse acerca de la posibilidad de sobreexplotación en comparación con los modelos tradicionales en los que no se considera reacción social. Los resultados obtenidos muestran que bajo estas nuevas condiciones el stock del estado estacionario aumenta y el comportamiento...

Environmental Amenities and Optimal Agricultural Land Use: The Case of Israel 31
Kan, Iddo; Haim, David; Rapaport-Rom, Mickey; Shechter, Mordechai.
This paper evaluates the effectiveness of changing land allocation among crops as a mechanism for increasing social welfare, where production profits and amenity benefits are augmented. A positive mathematical programming model is calibrated and applied to the northern part of Israel, using a crop-discriminating amenity-benefits function. Changes in land allocation increase social welfare by 2.4% nationwide, and by up to 15% on the regional level. Regional scale farming-profit losses amount to up to 6%. Due to the decreasing-return-to-scale nature of the amenity-benefits function, the inter-regional variability appears sensitive to the manner in which the country is divided into regions.

Changing the direction of environmental investment in Australia: Learnings from implementing INFFER 31
Marsh, Sally P.; Curatolo, April; Pannell, David J.; Park, Geoff; Roberts, Anna M.; Alexander, Jennifer.
Investment in natural resource management (NRM) by regional organisations in Australia has been widely criticised for failing to achieve substantial environmental outcomes. The Investment Framework for Environmental Resources (INFFER) is a tool for developing and prioritising projects to address environmental issues such as water quality, biodiversity decline, environmental pest impacts and land degradation. INFFER is an asset-based, targeted, and outcome-focussed approach to environmental investment, and as such is a very different and more rigorous approach to prioritising possible environmental projects than used previously by most catchment management organisations (CMOs) in Australia. From 2008 to 2010 INFFER has been trialled with CMOs. Evaluation...

The Economics of Wind Power with Energy Storage 31
Benitez, Pablo C.; Dragulescu, Lilianna; van Kooten, G. Cornelis.
We develop a nonlinear mathematical optimization program for investigating the economic and environmental implications of wind penetration in electrical grids and evaluating how hydropower storage could be used to offset wind power intermittence. When wind power is added to an electrical grid consisting of thermal and hydropower plants, it increases system variability and results in a need for additional peak-load, gas-fired generators. Our empirical application using load data for Alberta’s electrical grid shows that 32% wind penetration (normalized to peak demand) results in a net cost increase of $C5.20/ MWh, while 64% wind penetration could result in an increase of $12.50/MWh. Costs of reducing CO2 emissions are estimated to be $41-$56 per t CO2 . When...

Environmental Kuznets Curves for Carbon Emissions: A Critical Survey 31
Aslanidis, Nektarios.
The empirical finding of an inverse U-shaped relationship between per capita income and pollution, the so-called Environmental Kuznets Curve (EKC), suggests that as countries experience economic growth, environmental deterioration decelerates and thus becomes less of an issue. Focusing on the prime example of carbon emissions, the present article provides a critical review of the new econometric techniques that have questioned the baseline polynomial specification in the EKC literature. We discuss issues related to the functional form, heterogeneity, “spurious” regressions and spatial dependence to address whether and to what extent the EKC can be observed. Despite these new approaches, there is still no clear-cut evidence supporting the existence of the...

Testing Porter's Hypothesis: A Stochastic Frontier Panel Data Analysis of Dutch Horticulture 31
van der Vlist, Arno; Withagen, Cees; Folmer, Henk.
We propose a test of the Porter hypothesis for the Dutch horticulture sector, using a stochastic production frontier analysis allowing for an inclusion of policy variables to account for the effect of environmental policy of firm performance. We find considerable heterogeneity in the way firms react to environmental policy measures. Our estimation results indicate, for example, that a 1997 voluntary agreement covering energy, nutrient and pesticides use enhances technical efficiency of vegetable and plants growers, contrary to specialised flower growers. Specialised flower growers, however, did react to the 1993 multi-year agreement on energy reduction, contrary to vegetable and plant growers. Summarising, our findings are mixed but do not seem to reject...
