Eliciting public preferences for managing the public rights of way AgEcon
Morris, Joe; Colombo, Sergio; Angus, Andrew J.; Stacey, K.; Parsons, D.; Brawn, M.; Hanley, Nick.
Public Rights of Way (PROW) in England and Wales, provides a wide range of social and economic benefits to those other than owners of land. The protection and extension of PROW are an important way of encouraging people to engage in informal enjoyment of urban and rural areas, with beneficial consequences for health and welfare. In urban areas they provide networks of mobility and interaction for people at the community level, helping to reduce reliance on motorised transport. In the rural context they define access to the countryside, critically linked to recreation and tourism, as well as providing mobility networks for local residents. This study describes the use of a Choice Experiment (CE) to derive monetary estimates the social benefits of PROW in an...

The impacts of knowledge of the past on preferences for future landscape change AgEcon
Colombo, Sergio; Hanley, Nick; Ready, Richard C..
In this paper, we investigate whether people’s knowledge of the past influences their preferences and values towards future landscape change. “Knowledge of the past” is one aspect of the information set held by individuals, and a well-established finding in stated preference work is that changes in information can change preferences and values. The case studies used here relate to prospective changes in woodland cover in a UK national park the Lock Lomond and Trossachs. We find that people who are made aware that the landscape has changed over time are more likely to favour changes to the current landscape. Knowledge of the past therefore seems to have an impact on preferences for future landscapes.

What Determines Prediction Errors In “Benefits Transfer” Models? AgEcon
Colombo, Sergio; Hanley, Nick.
The aim of BT techniques is to provide decision makers with a monetary valuation of environmental goods and service in a cost-effective and timely manner, since original valuation studies are both expensive and time-consuming. Demands for environmental valuation estimates are rising in the policy community in both Europe and the US. In the UK, widespread use of benefits transfer has already occurred within policy making and regulatory bodies, for instance in the setting of water quality targets for private water companies and in the design of agrienvironmental policy. An important question is how big the errors are resulting from this practice, and how sensitive transfer errors are to how the benefits transfer is conducted. In this study we employ a choice...

Analisis economico de la erosion del suelo: valoracion de los efectos externos en la cuenca del Alto Genil AgEcon
Colombo, Sergio; Calatrava-Requena, Javier.
El presente trabajo trata de evaluar los efectos externos de la erosión del suelo mediante el uso del método del Experimento de Elección (EE). Tras una breve revisión de la literatura socioeconómica sobre el problema de la erosión y de los métodos empleados para evaluar sus efectos, se describe una aplicación a la evaluación de los efectos externos de la erosión del suelo en la cuenca del Alto Genil (Granada). El empleo del método del EE permite el cálculo de los valores asociados a los impactos más importantes de la erosión, así como proporcionar al administrador público información útil para la determinación de prioridades de gestión en el contexto de la planificación territorial. También se estima la variación de bienestar que la aplicación de políticas...

Análisis de la metodología de los puntos de corte para la identificación de las respuestas “inconsistentes” en los modelos de elección discreta AgEcon
Colombo, Sergio; Hanley, Nick; Bush, Glenn.
En el método del experimento de elección se supone que el entrevistado es perfectamente racional, está informado y maximiza su utilidad siguiendo una regla de elección perfectamente compensatoria. Sin embargo, es posible que los individuos empleen otras reglas de decisión en sus elecciones para simplificar el esfuerzo cognitivo del ejercicio propuesto. En este trabajo se emplea la metodología de los valores de corte para incorporar en el experimento de elección reglas de decisión no compensatorias, y se amplia esta metodología para identificar respuestas inconsistentes. Los resultados indican que el empleo de los valores de corte mejora la capacidad descriptiva de los modelos de elección, y puede ser muy útil para la identificación de inconsistencias en la...

Transferring the Benefits of Water Quality Enhancements in Small Catchments AgEcon
Black, Andrew; Colombo, Sergio; Hanley, Nick; Tinch, Dugald; Aftab, Ashar; Bergmann, E. Ariel.
The Water Framework Directive (WFD) sets targets of "Good Ecological Status" for water bodies across the EU. Environmental regulatory authorities must undertake economic analysis of all water bodies as part of the process of drawing up catchment management plans. In this paper, we test the transferability of benefit estimates across the kinds of smaller catchments where original benefits estimation is unlikely to be undertaken on grounds of costs. This is done in a context where agricultural-source nonpoint pollution and irrigation water abstraction are the main threats to ecological status.

Testing Choice Experiment for Benefit Transfer AgEcon
Colombo, Sergio; Calatrava-Requena, Javier; Conzalex-Roa, M.C..
Benefit transfer is a cost-effective method for estimating the value of environmental goods that relies on information obtained in previous studies. The multi-attribute approach of choice experiment should provide advantages in terms of benefit transfer allowing differences in environmental improvements between sites as well as differences in socio-economic and attitude characteristics between respondent populations. Furthermore, choice experiment allows the estimation of implicit prices and the welfare change for many scenarios. If the transferability of these values is confirmed, that would be good news for benefit transfer practitioners. This paper investigates the capability of choice experiment method to be used in environmental benefit transfer.

The Social-Environmental Impacts Of Renewable Energy Expansion In Scotland AgEcon
Bergmann, E. Ariel; Colombo, Sergio; Hanley, Nick.
Investments in renewable energy, such as new wind farms and hydro schemes, are being promoted as a new means of diversifying rural employment in Scotland*. However, such investments are associated with a range of environmental impacts which might be detrimental to other economic activities, such as those based on nature tourism. When designing policy instruments for more sustainable energy futures, therefore, the main goal is to generate the lowest possible adverse socio-economic and environmental impacts ensuring a certain degree of economic efficiency. We use a Choice Experiment to quantify peoples’ preferences over these multiple impacts of renewable energy in Scotland. We find that landscape, wildlife and air pollution impacts are all significant for...

Testing Different Types of Benefit Transfer in Valuation of Ecosystem Services: New Zealand Winegrowing Case Studies AgEcon
Baskaran, Ramesh; Cullen, Ross; Colombo, Sergio.
Most ecosystem services (ES) are neither priced nor marketed. Resource managers may fail to take into account degradation of unpriced services in their resource management decisions. Being able to estimate values for ES is fundamental to designing policies to induce resource users to provide (or improve) ES at levels that are acceptable to society. Conducting ecosystem valuation via non-market methods is costly and time consuming. Benefit Transfer (BT) using choice modeling (CM) is a potentially cost-effective method for valuing ES by transferring information from existing valuation studies (and study sites) to a target area of interest (policy sites). The prime objective of this paper is to examine the validity of BT and hence whether it is feasible to...

Análisis econométrico de la heterogeneidad de las preferencias de los individuos: aplicación a la valoración económica de la conservación del paisaje agrícola de montaña AgEcon
Colombo, Sergio; Hanley, Nick.
The need to account for respondents’ preference heterogeneity in stated choice models has motivated researchers to apply random parameter logit and latent class models. In this paper we compare these three alternative ways of incorporating preference heterogeneity in stated choice models and evaluate how the choice of model affects welfare estimates in a given empirical application. Finally, we discuss what criteria to follow to decide which approach is most appropriate. RESUMEN: La necesidad de incorporar la heterogeneidad en las preferencias de los individuos en los modelos de elección discreta ha llevado a los investigadores a emplear siempre más frecuentemente modelos de parámetros aleatorios o de clases latentes. En este artículo se comparan tres...
