Designing Policy for Reducing the Off‐farm Effects of Soil Erosion Using Choice Experiments

Soil erosion produces both on‐site private costs and off‐site social costs, such as desertification, rural depopulation, siltation of waterways and reductions in biodiversity. To design efficient policies, land use planners and decision makers need information on the relative weights of changes in these consequences, since policy alternatives, such as different management restrictions, will have varying impacts on these consequences of erosion. The research presented here uses the choice experiment method to evaluate these relative weights, using a case study in the Alto Genil and Guadajoz watersheds in southern Spain. We find that reductions in desertification, protection of water quality, protection of biodiversity, the area covered by the scheme, and the number of rural jobs safeguarded are all significant determinants of preferences over alternative policy designs.     

Testing Choice Experiment for Benefit Transfer with Preference Heterogeneity

Benefit transfer is a cost-effective method for estimating the value of environmental goods that relies on information obtained in previous studies. The multiattribute approach of choice experiments should provide advantages in terms of benefit transfer, allowing differences in environmental improvements between sites as well as differences in socioeconomic and attitude characteristics between respondent populations. This article investigates the capability of choice experiment method to be used in environmental benefit transfer when a random parameters approach is used to allow for preference heterogeneity: we find that the inclusion of respondents' taste heterogeneity reduces the magnitude of the transfer error.     

How Green are Exporters?

There is a well‐established theoretical and empirical literature that shows that exporters are more innovative than otherwise equivalent non‐exporters. In this article, we ask whether this is also true when it comes to the effects of adopting greener production techniques. Using an instrumental variables strategy based on UK firm level data, we find robust evidence that exporters are more likely to report their innovation as having a ‘high/very high’ environmental effect.     

Augmenting the Input–Output Framework for ‘Common Pool’ Resources: Operationalising the Full Leontief Environmental Model

In its initial formulation, the full Leontief (1970) Leontief, W. 1970. Environmental repercussions and the economic structure: an input–output approach. Review of Economics and Statistics, 52: 262–277. [Crossref], [Web of Science ®] [Google Scholar] environmental model augments the conventional Input–Output (IO) table by introducing pollution generation and separately identified pollution elimination sectors. Essentially it extends IO analysis to incorporate the use of a ‘common pool’ resource. Subsequent literature has either been analytical in nature or has concentrated on pollution generation but not cleaning activity. In this paper we generate an empirical full Leontief environmental IO system, based on augmenting the existing Scottish IO tables through endogenising waste generation and waste disposal activity. Due to weaknesses in data, our empirical results need to be treated with some caution. However, the construction of the extended IO system and the interpretation of the output and price multiplier results raise a number of interesting practical and conceptual issues. The analysis undertaken here can be extended to other ‘common pool’ resources such as the use of highways and irrigation systems.     

Professional Development Barriers and Benefits in a Tourism Knowledge Economy

This study investigates small to medium tourism enterprise (SMTE) owner–managers' intentions to seek professional development. SMTEs in a regional tourism destination were surveyed, and an exploratory factor analysis identified barriers to, and benefits of, professional development factors. Logistic regression analysis was used to predict SMTE owner–manager's intention to pursue professional development based on perceived benefits of and barriers to training factors, education level and business size. ‘Staff performance benefits’ and ‘time/cost barriers’ of owner–manager's intention to seek professional development opportunities for staff. ‘Business performance benefits’ predicted owner–manager's intentions to seek professional develop for themselves. Implications of the findings are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Rural versus urban preferences for renewable energy developments

Development of renewable energy resources, such as wind farms and hydro-electric schemes, are being promoted as a new method of expanding and diversifying employment in rural areas. However, such energy projects are associated with a range of environmental impacts which might be detrimental to other economic activities, such as those based on nature tourism. The authors use a Choice Experiment to quantify peoples' preferences over environmental and employment impacts that may result from the deployment of renewable energy projects in rural areas of Scotland, focussing in particular on any differences between the preferences of urban and rural dwellers, and on heterogeneity within these groups. Rural and urban households are shown to have different welfare gains which are dependent on the type of renewable energy technology and on the scale of project under consideration.     

Using Choice Experiments to Value the Environment

This paper we outline the “choice experiment” approach to environmental valuation. This approach has its roots in Lancaster's characteristics theory of value, in random utility theory and in experimental design. We show how marginal values for the attributes of environmental assets, such as forests and rivers, can be estimated from pair-wise choices, as well as the value of the environmental asset as a whole. These choice pairs are designed so as to allow efficient statistical estimation of the underlying utility function, and to minimise required sample size. Choice experiments have important advantages over other environmental valuation methods, such as contingent valuation and travel cost-type models, although many design issues remain unresolved. Applications to environmental issues have so far been relatively limited. We illustrate the use of choice experiments with reference to a recent UK study on public preferences for alternative forest landscapes. This study allows us to perform a convergent validity test on the choice experiment estimates of willingness to pay.     

The Role of Private Knowledge in Reducing the Information Wedge: A Research Note

Abstract:   In this first ever study to examine the marginal importance of collateral level vis‐à‐vis reputation in reducing information asymmetry, we find using unique data for UK business credit, that pre‐existing reputation is the single‐most important determinant in inducing a bank to extend a loan. Moreover, a bank responds positively to higher levels of collateral and negatively to higher credit requests. Similar to Cole (1998) , but controlling for collateral level, we find that it helps to have banked with the lender before. Non‐trivial information search costs imply an important role for reputation in extending credits.     

Macroeconomic Measures of 'Sustainability'

This paper reviews the policy need for indicators of 'sustainable development', and the impetus behind recent moves to establish official indicators. The range of indicators available from current economic theory is then examined. These measures may be divided into those based on flows and those based on stocks. Flow-based measures are essentially attempts to adjust Net National Product to transform it into an indicator of sustainability. Stock-based measures revolve around the concept of the natural and man-made capital stocks. We also consider the idea of Safe Minimum Standards as a sustainability indicator. The paper concludes that no currently-available single measure of sustainability is likely to be adequate.     

How accountability pressure on failing schools affects student achievement

Although an emerging body of evidence has shown that the threat of sanctions on low-performing schools can raise student test scores in the short run, the extent to which these test score improvements are due to schools' manipulation of the accountability system has remained uncertain. In this paper, I provide two new strands of evidence to evaluate the relative importance of educational reforms and gaming behavior in generating test score gains by threatened schools. First, using a regression discontinuity design that exploits Florida's system of imposing sanction threats on the basis of a cutoff level of performance, I estimate medium-run effects on student test scores from having attended a threatened elementary school. Threat-induced math improvements from elementary school largely persist at least through the first 1 to 2 years of middle school, while evidence for persistence of reading improvements is less consistent. Second, I analyze the effects of sanction threats on various features of educational production, and I find that sanction threats raise school spending on instructional technology, curricular development, and teacher training. Both strands of evidence are consistent with a predominant role for educational reforms in generating test score gains by threatened schools.
