A Choice Modelling Approach for Assessment of Use and Quasi-Option Values in Urban Planning for Areas of Environmental Interest AgEcon
Strazzera, Elisabetta; Cherchi, Elisabetta; Ferrini, Silvia.
This study adopts a discrete choice modelling methodology to evaluate individuals’ preferences over planning alternatives for an urban site of environmental interest. Since such projects involve some uncertainty and irreversibility, a special attention is devoted to the estimation of the quasi-option values which are associated to project development. Two distinct measures for the quasi-option value are estimated, and both coefficients indicate that the public places a significant value on reduction of the possibility of adverse irreversible effects: a more prudent development strategy is valued about four times more than a procedure that provides a lesser hedge against undesired outcomes. Furthermore, the study involved elicitation of intertemporal...

A comparison of the economic and environmental performances of conventional and organic farming: evidence from financial statements AgEcon
Argiles, Josep M.; Brown, Nestor Duch.
While conventional farming systems face serious problems of sustainability, organic agriculture is seen as a more environmentally friendly system since it favours renewable resources, recycles nutrients, uses the environment’s own systems for controlling pests and diseases, sustains ecosystems, protects soils, and reduces pollution. At the same time organic farming promotes animal welfare, the use of natural foodstuffs, product diversity and the avoidance of waste, among other practices. However, the future of organic agriculture will depend on its economic viability and on the determination shown by governments to protect these practices. This paper performs panel regressions with a sample of Catalan farms (Spain) to test the influence of organic farming...

A Joint Estimation Method to Combine Dichotomous Choice CVM Models with Count Data TCM Models Corrected for Truncation and Endogenous Stratification AgEcon
Gonzalez, Juan Marcos; Loomis, John B.; Gonzalez-Caban, Armando.
We update the joint estimation of revealed and stated preference data of previously published research to allow for joint estimation of the Travel Cost Method (TCM) portion using count data models. The TCM estimation also corrects for truncation and endogenous stratification as well as overdispersion. The joint estimation allows for testing consistency of behavior between revealed and stated preference data rather than imposing it. We find little gain in estimation efficiency, but our joint estimation might make a significant improvement in estimation efficiency when the contingent valuation scenarios involve major changes in site quality not reflected in the TCM data.

A Multifunctional Comparison of Conventional versus Alternative Olive Systems in Spain by Using AHP AgEcon
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...

Addressing the wicked problem of water resource management: An ecosystem services approach AgEcon
Hearnshaw, Edward J.S.; Tompkins, Jean-Marie; Cullen, Ross.
This paper develops a systematic assessment of the sustainability of ecosystem services provided by rivers impacted by water storage projects. Given the conflicting preferences amongst stakeholders and the incomplete, uncertain and contradictory understanding about river ecology it is recognized that managing water resources sustainably is a wicked problem. In order to address this wicked problem, the methods of multi-criteria analysis and graph analysis are applied, in accordance with integrated water resource management, to assess the potential of investing in water storage projects and explore for sustainable solutions through the construction of an ecosystem services index.

An Application of Mixed Logit Estimation in the Analysis of Producers’ Stated Preferences AgEcon
Kipperberg, Gorm; Bond, Craig A.; Hoag, Dana L..
This paper analyzes Colorado Corn producers’ preferences over both private- and environmental public-good production system attributes. Current production practices are characterized by intensive water and chemical use, resulting in non-point source pollution to water bodies as well as soil erosion problems. Data from a stated preference survey are employed to analyze key attributes of experimentally configured irrigation systems, proposed as alternatives to current practices. Panel mixed logit estimations find positive preferences for profit, risk reduction, and, importantly, systems with less environmental impact in terms of nitrate leaching and soil erosion. The results also find presence of significant preference heterogeneity and a complementary...

An Economic Analysis of Bushfires Management Programs AgEcon
Ganewatta, Gaminda; Grahlmann, Linda; Handmer, John.
Allocating scare resources for fire management strategies requires information on the extent of economic losses from bushfires and the efficiency of alternatives. Despite the severity of bushfires, there is no agreed approach in Australia for estimating economic losses from fires nor for evaluating the economic efficiency of alternative suppression strategies. The poster proposes approaches to assess the economic effects of bushfires on local and state economies and sets out models to evaluate the economic efficiency of two key bushfire management strategies: presuppression and suppression. The first model arises from questions concerning the value of pre-suppression (before the fire) fuel reduction activities, and the estimation of an economically optimal...

An Economic Assessment of the Amenity Benefits Associated with Alternative Coastal Protection Options AgEcon
Christie, Mike; Colman, Oliver.
Current government guidelines for the appraisal of coastal defence projects in the UK do not require that non-market amenity benefits to be considered . However, a new option in coastal defence, namely multi-purpose reefs, provides an opportunity to integrate coastal defence with significant amenity provision. This paper reports the findings of a choice experiment study that evaluated the amenity benefits of four alternative coastal defence systems currently being considered for Borth in west Wales. The results indicate that traditional coastal defence options such as timber and rock groynes do not generate amenity benefits, while a multipurpose reef would generate significant benefits in terms of improvements in the visual appeal of the beach, safer...

An Economic Assessment of the Impacts of the MOSE Barriers on Venice Port Activities AgEcon
Vergano, Lucia; Umgiesser, Georg; Nunes, Paulo A.L.D..
Due to its hydro-geological features, the lagoon of Venice is especially vulnerable to climate change. In particular, it is strongly affected by gradual global warming that brings about the so-called ‘acqua alta’ (high water) phenomenon with greater frequency and intensity. In order to protect the city of Venice from the more and more frequent phenomenon of flooding, some protective measures have been adopted. Among them, the system of mobile barriers commonly known as MOSE: however, by separating the lagoon from the Adriatic Sea, it interferes with ship traffic and has negative impacts on port activities. Against this background, the aim of the present work is to provide an estimate of the direct costs of ship traffic interruption due to the functioning...

An Improved Method for Calibrating Purchase Intentions in Stated Preference Demand Models AgEcon
Davies, Stephen P.; Loomis, John B..
The Orbit demand model allows the magnitude of the calibration to stated purchase intentions to vary based on the magnitude of the stated quantities. Using an empirical example of stated trips, we find that the extent of calibration varies substantially with less correction needed at small stated trips (–25%) but larger corrections at higher quantities of stated visits (–48%). We extend the Orbit model to calculate consumer surplus per stated trip of $26. Combining the calibrations in stated trips and value per trip, the Orbit model provides estimates of annual benefits from 60% to 111% less than the count data model.

Análisis de intensidades energéticas y emisiones de CO2 a partir de la matriz de contabilidad social de Andalucía del año 2000 AgEcon
Cardenete, Manuel Alejandro; Fuentes Saguar, Patricia D.; Polo, Clemente.
RESUMEN: En este artículo se estiman las intensidades energéticas y emisiones de CO2 para la economía andaluza en el año 2000. Las intensidades energéticas de las ramas productivas se calculan en varios escenarios empleando un modelo SAM especificado con la matriz de contabilidad social elaborada por los autores. Las emisiones se estiman con el modelo input-output, distinguiendo la polución intermedia de la originada por la demanda final. Los resultados muestran la existencia de importantes variaciones en intensidades entre ramas y también las sustanciales variaciones que acaecen al endogeneizar el consumo y la inversión. La estimación de las emisiones en el año base resulta bastante satisfactoria y las simulaciones realizadas muestran el sustancial...

Análisis del impacto medioambiental derivado de las actividades económicas. Aplicación a una economía regional AgEcon
Flores, Monica; Mainar, Alfredo J..
The goal of this paper is to analyse the households’ environmental impact in a regional economy, including the household direct impact as well as the impact associated with the production of goods and services of the household demand. Moreover, per capita ecological impacts for each household category according to income level are obtained. We focus on water consumption, and water and atmospheric pollution. The framework is based on a regional SAMEA (Social Accounting Matrix and Environmental Accounts), and vertically integrated environmental indicators using the Leontief model. An application is carried out for the Aragon case.

Aportaciones desde la economía de la adaptación a la toma de decisiones sobre cambio climático: un ejemplo para la Comunidad Autónoma del País Vasco AgEcon
Galarraga, Ibon; Oses, Nuria; Markandya, Anil; Chiabai, Aline; Khantun, Kaysara.
As a consequence of Climate Change sea level rise as well as a change in the intensity and propensity of rain are expected in the Basque Country. Valuing the costs and benefits of adapting to these changes becomes an important piece of information for the planning process. This paper develops two methodological frameworks. The first one devoted to estimating the economic impacts to urban areas of an increase in the risk of flooding. The values estimated for the Nervión river in the city of Amurrio (Álava) indicate that the average expected damage will increase in 15 per cent as a consequence of CC (from €56,097 to €64,451). For an extreme episode the total loss could increase to €20 million. The second framework is oriented towards the valuation of the...

Are Consumers Willing to Pay for Organic When the Food is Already Local? AgEcon
Connolly, Cristina; Klaiber, H. Allen.
The emergence of community supported agriculture (CSA) farms has provided a new way for small farms to remain competitive while engaging their local community through direct marketing. In this study, we report on some of the first revealed preference valuation of CSA attributes, including the willingness to pay for competing organic certification programs. Using data on the prices and attributes of 188 CSA farms spanning Ohio and Pennsylvania we estimate willingness to pay measures from both hedonic and nearest-neighbor matching methods. Results from a semi-log hedonic reveal a willingness to pay of approximately 9% for organic branding compared to natural, which translates into an additional $48 per summer season share. We also find a statistically...

Assessing community values for reducing agricultural emissions to improve water quality and protect coral health in the Great Barrier Reef AgEcon
Rolfe, John; Windle, Jill.
Key policy issues relating to protection of the Great Barrier Reef from pollutants generated by agriculture are to identify when measures to improve water quality generate benefits to society that outweigh the costs of reducing pollutants. The research reported in this paper makes a key contribution in several key ways. First, it uses the improved science understanding about the links between management changes and reef health to bring together the analysis of costs and benefits of marginal changes, helping to demonstrate the appropriate way of addressing policy questions relating to reef protection. Second, it uses the scientific relationships to frame a choice experiment to value the benefits of improved reef health, and links improvements explicitly to...

Assessing farm sustainability. An application with the Italian FADN sample. AgEcon
Povellato, Andrea; Bodini, Antonella; Longhitano, Davide; Scardera, Alfonso.
As policy makers, taxpayers and consumers are willing to know the actual contribution of farming to natural and social environment, sustainability and sustainable development arose as key issues in public debates. Sustainability is a multifaceted concept that includes environmental, economic and social objectives and policy makers need information to take effective decisions. Analysts should rank decisional units according to sustainability criteria and should offer to policy makers more and more insights on the different points of view behind the three dimensions of sustainability. Within the current FADN database sustainability indicators have been identified. In some cases estimations have been necessary and in some other cases thanks to allocation of...

Assessing national values to protect the health of the Great Barrier Reef AgEcon
Rolfe, John; Windle, Jill.
The aim of this study was to estimate the values to protect the health of the Great Barrier Reef (GBR) at the national level and to examine the effects of distance decay on valuation estimates. A split-sample choice-modelling experiment was conducted in six locations: a regional town within the GBR catchment area (Townsville); Brisbane, the state capital approximately 450 km from the southern limit of the GBR; and four other capital cities (Sydney, Melbourne, Adelaide and Perth) ranging from nearly 1,000 km to over 4,000 km from Brisbane. The results suggest that the average WTP across Australian households is $21.68 per household per annum for five years. There was some evidence of distance decay in values. Most decline occurred once outside the home...

Assessing the Economic Impacts of Climate Change. An Updated CGE Point of View AgEcon
Bosello, Francesco; Eboli, Fabio; Pierfederici, Roberta.
The present research describes a climate change integrated impact assessment exercise, whose economic evaluation is based on a CGE approach and modeling effort. Input to the CGE model comes from a wide although still partial set of up-to-date bottom-up impact studies. Estimates indicate that a temperature increase of 1.92°C compared to pre-industrial levels in 2050 could lead to global GDP losses of approximately 0.5% compared to a hypothetical scenario where no climate change is assumed to occur. Northern Europe is expected to benefit from the evaluated temperature increase (+0.18%), while Southern and Eastern Europe are expected to suffer from the climate change scenario under analysis (-0.15% and -0.21% respectively). Most vulnerable countries are the...

Assessing the impact of the EU Common Agricultural Policy pillar II support using micro-economic data AgEcon
Buysse, Jeroen; Verspecht, Ann; Van Huylenbroeck, Guido.
The paper uses the case of Flemish investment support to make a quantitative analysis of pillar II support based on micro-economic data from the FADN and the administrative dataset of the investment support fund. A dynamic panel estimation quantifies the effect of support for settingup young farmers, structural investment support and support for investments on farm diversification, animal welfare or environmental investments.. The results show that investment support for farm diversification and structural support increase the total output and the income. Environmental investment support increase costs and decrease the farm income without a significant impact on output. The conclusion for the national debate is that the structural and the diversification...
