Meta-Functional Benefit Transfer for Wetland Valuation: Making the Most of Small Samples

This study applies functional Benefit Transfer via Meta-Regression Modeling to derive valuation estimates for wetlands in an actual policy setting of proposed groundwater transfers in Eastern Nevada. We illustrate how Bayesian estimation techniques can be used to overcome small sample problems notoriously present in Meta-functional Benefit Transfer. The highlights of our methodology are: (i) The hierarchical modeling of heteroskedasticity; (ii) The ability to incorporate additional information via refined priors; and (ii) The derivation of measures of model performance with the corresponding option of model-averaged Benefit Transfer predictions. Our results indicate that economic losses associated with the disappearance of these wetlands can be substantial and that primary valuation studies are warranted.

The effects of EU agricultural policy changes on farmers' risk attitudes

This analysis utilises a model of production under risk estimatedon Finnish farm-level data to measure farmers' risk attitudesin a changing policy environment. We find evidence of heterogeneousrisk preferences among farmers, as well as notable changes overtime in farmers' degree of risk aversion. This result is dueto the increase in the non-random part of farm income generatedby the policy change after Finland's European Union accession.The analysis confirms the assertion that agricultural policiesthat are decoupled from production do affect input use and cropmix through their effect on farmers' risk attitudes.     

产业转移的新经济地理学解释

不同于传统的产业转移理论,新经济地理学(NEG)在规模报酬和垄断竞争框架下解释产业转移现象,认为产业转移的基础不必然是第一自然的差异,在完全相同的均质空间下,产业转移也能出现,并且对产业转移的相关原理给予了独特的解释。以现有文献为基础,本文从产业转移机制、产业转移的特征与规律、产业转移的福利效应以及促进产业转移的政策效应四个方面总结了产业转移的NEG相关解释。     

An assessment of market-based approaches to providing ecosystem services on agricultural lands

Market-based approaches are increasingly being advocated as tools for achieving the conservation of ecosystem services. We examine the reasons why markets so far appear to have failed to provide an efficient allocation of many ecosystem services, and identify the conditions under which markets deliver efficient resource allocation. We discuss different forms of market-based approaches to ecosystem services and identify the characteristics of services that make them better suited to one or another of these approaches. We find that lack of low-cost measurability and valuation currently precludes efficient allocation of many ecosystem services through market-based approaches. Still, some forms of market-based approaches hold promise for cost-effectively managing some ecosystem services provided by and to agricultural lands. In many cases some form of well-designed government involvement will be required to seek outcomes that protect the public interest.

The Link Between Gasoline Prices and Vehicle Sales

This paper examines the link between fuel prices and sales of cars and trucks. U.S. automakers have long denied that such a link exists. One source of this false belief is an obsession with the crude count of units sold, equating Hummers with Minis. Another source is the conventional “wisdom” that Americans are unwilling to pay for fuel economy. The paper presents theoretical reasons and market evidence that refute Detroit’s conventional wisdom. American manufacturers’ reaction to rising fuel prices over the last few years revealed the shortcomings of the U.S. automakers’ recent product and powertrain strategies. The effect of rising fuel prices has, in effect, been offset by reducing prices of vehicles in inverse proportion to fuel economy. Thus, unit sales of large SUVs could be maintained, but their revenue (and profit) fell because vehicle prices were cut, directly or indirectly. The paper concludes with a few practical guidelines that business economists should use to prevent their companies from experiencing the recent massive losses experienced by the U.S. automobile industry.
