农业保险的经济学属性分析

本文从经济学的角度，分析了农业保险的性质，指出农业保险具有风险系统性、信息不对称性以及外部性的特殊属性。针对这三大属性，作者认为再保险、相互组织和政府干预是解决农业保险市场失灵的主要措施。     

森林生态效益外部性会计计量的能值分析模式

能值分析理论与方法应用于森林生态效益外部性计量的基本思路是,通过对森林生态系统的能流分析,将森林生态效益生态因子量经由能值转换率转化为同一标准的太阳能值,再结合本地区的能值/货币比得到森林生态效益及外部性价值。对江苏连云港墟沟林场的案例研究显示,该林场2003年的森林生态效益能值主要体现在保土、涵养水源和防风效益。     

Industrial structure and innovation - evidence from European regions

Whether the composition of industrial activity influences innovation is the key question of this paper. The analysis is based on a model that integrates different kinds of diversity measures aiming at capturing Jacobs externalities, a production specialisation measure aiming at capturing Marshall-Arrow-Romer (MAR) externalities and regions as well as sector specific variables. Tested with an extended sample of 153 European regions and 16 manufacturing sectors, the estimates suggest that both kinds of externalities significantly influence innovation, although the influence of Jacobs externalities is more important in the context of high density regions as well as for high tech sectors.JEL Classification: R00, O18, O31Lydia Greunz: The author wishes to thank Henri Capron and two anonymous referees for their useful comments and suggestions.

Consistent solutions for cooperative games with externalities

In order to calculate the worth of a coalition of players, the coalition needs to predict the actions of outsiders. We propose that, for a given solution concept, such predictions should be made by applying the solution concept to the “reduced society” consisting of the non-members. We illustrate by computing the r-core for the case of Bertrand competition with differentiated commodities.     

The relative decline of a Musgrave ‘Merit Good:’ the case of public support of flagship public universities

Fifty years ago, Richard Musgrave put forward the notion of a “merit good”—one that despite its virtue would be undersupplied and under consumed in a free market economy driven by traditional notions of consumer sovereignty. Higher education is considered by many to be a merit good because they believe it generates highly desirable spin-off effects. If higher education has been a merit good, then that status appears to be disappearing. Declining state funding for higher education, increasing tuition rates and highly successful fund-raising by independent institutions have diminished public flagship universities, at least relatively. Consequently, their rankings have declined.

Weak complementarity and production

This paper describes how weak complementarity, a common assumption to characterize consumer preferences for recovering measures of willingness to pay for nonmarketed environmental resources, can be used to evaluate the effects of pollution that may affect profits or costs. In such cases, pollution serves as an externality imposed by third parties on production activities.     

环境规制、政府研发资助对绿色技术创新的影响——基于中国内地省级层面数据的实证分析

绿色技术创新是突破“经济-环境”压力的关键所在。政府行为能够有效弥补绿色技术创新在市场经济体制下存在的天然不足。为进一步探究政府政策对绿色技术创新的影响，基于绿色技术创新的“双重外部性”特征，以我国内地31个省（市、区）2009-2017年面板数据为样本，探究环境规制、政府研发资助对绿色技术创新的直接影响效应及交互效应。结果发现，环境规制与政府研发资助均对绿色技术创新有显著正向影响，政府研发资助影响效应更大；两者互补耦合更有利于促进绿色技术创新。     

Too hot to handle?: Benefits and costs of stimulating the use of biofuels in the Swedish heating sector

This paper evaluates the impact of changes in current Swedish energy taxation by analyzing a panel of approximately 150 district heating plants in Sweden. We estimate plant-specific production functions and derive the economic repercussions of changing the energy tax system. We also estimate the resulting changes of emissions of Sulfur, NO_x, particulates and CO₂. Our results raise the issue of whether or not the Swedish tax system needs to be complemented with additional environmental taxes, covering, say, emissions of particulates. Because the geographical variation of damages is likely to be substantial, an overall re-assessment of current regulatory schemes seems preferable.     

Modeling production externalities in the maquila industry

In the past decade, the maquiladora export industry surpassed both tourism and petroleum products to become the number one source of earned foreign exchange for Mexico. The continued growth of the maquila industry suggests that there may be significant production spillovers into the local environments. Dynamic modeling, using STELLA, provides a framework for quantifying the environmental impacts emanating from the growth of the maquila industry, focusing on wastewater treatment consequences and resulting infrastructural policy considerations. Such detailed modeling of industrial, infrastructural, and ecological linkages has not yet been a feature of research on this region, despite the potential for significant human health ramifications. An environmental model is therefore developed for two focal urban communities, Nogales and Mexicali, facing potential wastewater treatment concerns due to the growth of nearby maquila factories. In the former case, the analysis revealed the inadequacy of the capacity planning for the treatment of effluent; in the latter case, conservative projections reveal that the system upgrades should be able to handle demands through 2020.     

Changes in the firms behavior after the opening of markets of allowances

This paper focuses on the influence on the general equilibrium of an economy of the opening of markets of allowances, such as the European Union Emission Trading Scheme. Assuming there existed an equilibrium before the opening of allowances’ markets, we describe the changes in the firms behavior which guarantee that an equilibrium can be reached in the enlarged economy. Hence we describe under which conditions the economy can undergo the opening of markets of allowances. This paper is a substantial improvement of previous work in collaboration with Alexandrine Jamin (Jamin and Mandel 2006).The author is grateful to Professor Jean-Marc Bonnisseau for his guidance and to an anonymous referee whose comments led to substantial improvements of the paper.
