Última The Problem of the Commons: Still Unsettled after 100 Years AgEcon Stavins, Robert N.. The problem of the commons is more important to our lives and thus more central to economics than a century ago when Katharine Coman led off the first issue of the American Economic Review. As the U.S. and other economies have grown, the carrying-capacity of the planet - in regard to natural resources and environmental quality — has become a greater concern, particularly for common-property and open-access resources. The focus of this article is on some important, unsettled problems of the commons. Within the realm of natural resources, there are special challenges associated with renewable resources, which are frequently characterized by open access. An important example is the degradation of open-access fisheries. Critical commons problems are also...

Ano: 2010 URL: http://purl.umn.edu/98048 Agricultural Sustainability and the Introduction of Genetically Modified Organisms (GMOs) AgEcon Tisdell, Clement A.. In order to cater for the predicted growth in global population and aspirations for increased living standards, the world needs to increase substantially its level of agricultural production and sustain agriculture’s increased productivity. New technologies may enable this to occur but they also bring with them increased sustainability problems. There are many complex dimensions to achieving agricultural sustainability such as deciding on what agricultural attributes are worth sustaining and considering what trade-offs in objectives are required. These issues are discussed from a conceptual point of view. It is also shown using economic theory that market-based agriculture limits the opportunity for individual farmers to adopt sustainable agricultural...

Ano: 2009 URL: http://purl.umn.edu/55335 Modeling Demand for Outdoor Recreation Settings with Choice Based Data Accounting for Exogenous and Endogenous Stratification AgEcon Sardana, Kavita; Bowker, James Michael; Bergstrom, John C.. Estimating regional demand models by pooling different samples without correcting for such differences causes model misspecification as each sample belongs to a different population. Weighted regression using Pseudolikelihood to account for differences in sample population with adjustment for heteroskedasticity improves efficiency but the estimates are biased. We estimate regional demand for National Forest settings types in the southeastern states of U.S using weighted and unweighted regression. Using estimation of demand for National Forests as a case study, we resolve problems relating to inference about the data generating process when different samples are pooled together. We show that though efficiency of weighted estimates improves after correcting...

Ano: 2010 URL: http://purl.umn.edu/61046 Linkage of Tradable Permit Systems in International Climate Policy Architecture AgEcon Jaffe, Judson; Stavins, Robert N.. Cap-and-trade systems have emerged as the preferred national and regional instrument for reducing emissions of greenhouse gases throughout the industrialized world, and the Clean Development Mechanism — an international emission-reduction-credit system — has developed a substantial constituency, despite some concerns about its performance. Because linkage between tradable permit systems can reduce compliance costs and improve market liquidity, there is great interest in linking cap-and-trade systems to each other, as well as to the CDM and other credit systems. We examine the benefits and concerns associated with various types of linkages, and analyze the near-term and long-term role that linkage may play in a future international climate policy...
