Última Environmental Policy, Spatial Spillovers and the Emergence of Economic Agglomerations AgEcon Kyriakopoulou, Efthymia; Xepapadeas, Anastasios. We explain the spatial concentration of economic activity, in a model of economic geography, when the cost of environmental policy - which is increasing in the concentration of emissions - and an immobile production factor act as centrifugal forces, while positive knowledge spillovers and iceberg transportation costs act as centripetal forces. We study the agglomeration effects caused by trade-offs between centripetal and centrifugal forces. The above effects govern firms’ location decisions and as a result, they define the distribution of economic activity across space. We derive the rational expectations equilibrium and the social optimum, compare the outcomes and characterize the optimal spatial policies.

Ano: 2009 URL: http://purl.umn.edu/54289 Economics of Sourcing Cellulosic Feedstock for Energy Production AgEcon Gustafson, Cole R.; Maung, Thein A.; Saxowsky, David M.; Nowatzki, John; Miljkovic, Tatjana. This study investigates the economics of supplying wheat straw and corn stover within 100 mile radius of a potential new biorefinery in southeast North Dakota. In particular, straw and stover total delivery costs, potential straw and stover supply sites and least cost transportation routes are identified using a linear programming transport model and a GIS (Geographic Information Systems) mapping system. We show that USDA/NRCS (Natural Resources Conservation Service) future crop residue removal rate policies will be important for determining whether it is economically viable to harvest crop residues as potential feedstock for energy generation. Increase in residue removal rates narrow the size of residue supply areas and consequently result in lowering...
