AN AGENDA FOR THE STUDY OF LAND USE, WILDERNESS DESIGNATION, AND RESOURCE REGULATION IN THE AMERICAN WEST AgEcon
Batabyal, Amitrajeet A..
Atemporal and intertemporal use of public lands, the determination of optimal levels of wilderness designation and habitat preservation, and the appropriate regulation of natural resources have all been "hot button" issues in the American West for quite some time now. In this paper, I propose and describe a research agenda which promises to yield interesting and useful new policy insights into these fractious resource issues.

Cairo Evaluation Clinic: Thoughts on Randomized Trials for Evaluation of Development AgEcon
Karlan, Dean S..
We were asked to discuss specific methodological approaches to evaluating three hypothetical interventions. This article uses this forum to discuss three misperceptions about randomized trials. First, nobody argues that randomized trials are appropriate in all settings, and for all questions. Everyone agrees that asking the right question is the highest priority. Second, the decision about what to measure and how to measure it, i.e., through qualitative or participatory methods versus quantitative survey or administrative data methods, is independent of the decision about whether to conduct a randomized trial. Third, randomized trials can be used to evaluate complex and dynamic processes, not just simple and static interventions. Evaluators should aim...

CAN ECONOMETRIC ANALYSIS MAKE (AGRICULTURAL) ECONOMICS A HARD SCIENCE? CRITICAL REMARKS AND IMPLICATIONS FOR ECONOMIC METHODOLOGY AgEcon
Petrick, Martin.
This paper argues that mainstream economics does not follow the positivist research tradition it (often implicitly) claims to follow and expresses some serious doubt that econometrics in particular can make economics a hard science. Mathematical rigour and sophisticated statistical techniques may be regarded as persuasive analytical tools in economics, but their mere application does not guarantee good research practice. The paper outlines an alternative methodological view of pragmatic instrumentalism in which the well known tools of economic analysis can find a new place. Instead of relying on a narrow rule that purports to produce universal truth, this view encourages to increase the target area for questioning and probing. Much more attention is paid...

Effectiveness of Nitrate Policy in Flanders (1990-2003): Modular Modelling and Response Analysis AgEcon
Veraet, Mieke; Lauwers, Ludwig H.; Lenders, Sonia; Overloop, Stijn.
The impact of current nitrate policy measures in Flanders is estimated. A modular modelling system has been developed for comparing response and pressure indicators and for decomposing the response impact of policy measures. Compared to 1990, the internalised manure surplus is reduced to zero, whereas the distance to target of the soil surface balance to the water quality standard dropped only with 58%. Source-linked and sink-related measures each account for about the half of the manure surplus reduction. The impact of abatement technologies is minor. The modular approach helps to unravel the discrepancy between pressure and response and to propose policy alternatives.

El valor de la flexibilidad en la valoracion de inversiones acuícolas AgEcon
Sempere, Loreto Pardo; Alcaide, Jose Javier Rodriguez.
Las fuertes inversiones iniciales que son necesarias para comenzar una actividad acuícola, unidas al período tan dilatado del ciclo de explotación y al riesgo que esta actividad comporta, son situaciones que comprometen el futuro de la actividad cuya continuidad pasa necesariamente por la consecución de la viabilidad económica. Por ello, es importante prestar atención a los estudios que justifiquen esta viabilidad económica considerando aspectos tales como la propia flexibilidad operativa o el valor estratégico que tiene cada proyecto de inversión, a menudo considerados factores críticos para la supervivencia. Desde esta perspectiva, se pone de manifiesto la necesidad y la oportunidad de la investigación, basado en la aplicación del método de Opciones...

Impacts of Sample Size and Quality-Adjusted Imputed Prices on Own-Price Elasticities Estimated Using Cross-Sectional Data AgEcon
Stockton, Matthew C..
Cross-sectional data sets containing expenditure and quantity information are typically used to calculate quality-adjusted imputed prices. Do sample size and quality adjustment of price statistically alter estimates for own-price elasticities? This paper employs a data set pertaining to three food categories-pork, cheese, and food away from home-with four sample sizes for each food category. Twelve sample sizes were used for both adjusted and unadjusted prices to derive elasticities. No statistical differences were found between own-price elasticities among sample sizes. However, elasticities that were based on adjusted price imputations were significantly different from those that were based on unadjusted prices.

Labor Risk Attributes in the Green Industry: Business Owners' and Managers' Perspectives AgEcon
Bitsch, Vera; Harsh, Stephen B..
Managers of greenhouses, nurseries, and landscape contractors participated in five focus group discussions on labor-related risks. Managers conceptualize labor risks along the human resource management process: (1) recruitment and selection, (2) training and development, (3) performance evaluation and discipline, (4) careers and relationships, and (5) compensation packages. In addition, they identified (6) immigrant employees and (7) labor laws and regulations as sources of risk. They recognized a large number of risk-increasing attributes, but also a number of mediating strategies to reduce these risks.

Mapping the Evolution of "Clusters": A Meta-analysis AgEcon
Maggioni, Mario A.; Gambarotto, Francesca; Uberti, Teodora Erika.
This paper presents a meta-analysis of the “cluster literature” contained in scientific journals from 1969 to 2007. Thanks to an original database we study the evolution of a stream of literature which focuses on a research object which is both a theoretical puzzle and an empirical widespread evidence. We identify different growth stages, from take-off to development and maturity. We test the existence of a life-cycle within the authorships and we discover the existence of a substitutability relation between different collaborative behaviours. We study the relationships between a “spatial” and an “industrial” approach within the textual corpus of cluster literature and we show the existence of a “predatory” interaction. We detect the relevance of...

Multiregional Invasive Species Management: Theory and an Application to Florida's Exotic Plants AgEcon
Kim, C.S.; Lee, Donna J.; Schaible, Glenn D.; Vasavada, Utpal.
This research develops a multiregional optimal control model that incorporates regional allocation of a public budget for controlling invasive plants when regionally differential recreation demand functions and species control costs are present. Our equimarginal condition for optimal budget allocation equates the relative marginal economic benefits per dollar spent across regions. The model was applied to Florida Public Conservation Land regions, and results indicate that the magnitude of an annual management budget affects its distribution among species management regions, but the size of the intrinsic growth rate does not affect the pattern of budget allocation among regions.

Properties of Flexible Functional Forms for Modeling Bilateral Export Supply and Import Demand in Multi-Country Agri-Food Models AgEcon
Winter, Etti Maria; Frohberg, Klaus.
This paper illustrates the opportunities of incorporating more advanced functional forms into multi-country trade policy models. It suggests the use of flexible forms such as the Symmetric Generalized McFadden Function (SGMF) or the Normalized Quadratic-Quadratic Expenditure System (NQQES). Particularly if issues namely trade in differentiated products, preferential trade and effects of standards and traceability on bilateral trade are considered the NQQES offers attractive properties since it allows estimating variety specific expenditure elasticities which might compensate for example increased certification costs. A second aim of the paper refers to the critique on the handling of model parameters in calibrated policy models. In general, employed...

Sustainable Decision-making: The State of the Art from an Economics Perspective AgEcon
Toman, Michael.
Government, corporate and other decision makers are more and more often being urged to 'act sustainably' and to pursue policy paths toward 'sustainable development.' However, application of these concepts is hampered by serious interdisciplinary disagreements about the interactions of humans with their environment. Moreover, reducing disagreements about sustainability cannot be achieved solely through an improvement in scientific knowledge. These observations lead me to express skepticism about the capacity of any more or less mechanistic rule, economic, scientific or otherwise, to provide definitive and reliable answers about sustainable policies or conduct. However, there are processes and procedures that can help guide decision-making. I underscore the...
