Cow-Calf Producer Perceptions Regarding Individual Animal Traceability AgEcon
Schulz, Lee L.; Tonsor, Glynn T..
This study provides valuable insights into cow-calf producer voluntary participation in the National Animal Identification System and producers’ perceptions of several issues critically impacting the success of voluntary traceability systems. Cow-calf producers believe that the most important issues to the U.S. beef industry in designing a national, individual animal traceability system are monitoring/managing disease, maintaining current foreign markets, accessing foreign markets, and increasing consumer confidence. Furthermore, producers are concerned with cost, liability, reliability of technology, failure of system to meet stated goals, and confidentiality of information associated with these systems.

Do Refuge Requirements for Biotechnology Crops Promote Economic Efficiency? Some Evidence for Bt Cotton AgEcon
Livingston, Michael J.; Storer, Nicholas P.; Van Duyn, John W.; Kennedy, George G..
We examine producer behavior, resistance evolution, and returns under alternative refuge requirements in an eastern North Carolina region with multiple corn, cotton, and soybean fields infested by a mobile pest. Returns are highest, pyrethroid sprays occur least frequently, and pyrethroid resistance evolution is delayed most effectively with no refuge requirement. Complying with the current 20% refuge requirement costs the producer $8.67 per cotton acre, or $34.21 per non-transgenic insecticidal (Bt) cotton acre. Returns are highest under each refuge requirement when one-toxin Bt cotton is not phased out; however, removal of the technology at the earliest phase-out date minimizes regional pyrethroid sprays.

ECONOMIC EFFECTS OF A BAN AGAINST ANTIMICROBIAL DRUGS USED IN U.S. BEEF PRODUCTION AgEcon
Mathews, Kenneth H., Jr..
Economic effects for three scenarios of antimicrobial drug use in livestock production -- a no-ban scenario and two levels of bans -- are examined through cost minimization and a partial equilibrium analysis. Results indicate that regulating antimicrobial drug use in livestock production would increase per-unit costs of producers previously using drugs and reduce beef supplies in the short run, reducing consumer surplus. Producers not previously using drugs would benefit from short-run price increases.

ENVIRONMENTAL REGULATION AND THE OPTIMAL LOCATION OF THE FIRM UNDER UNCERTAINTY AgEcon
Isik, Murat.
This paper examines the optimal location of a competitive firm in response to environmental costs imposed by the abatement investment and taxes when the cost of the environmental regulation varies spatially under uncertainty. It contributes to the literature by incorporating the spatial setting into a risk-averse firm's location decisions in the presence of environmental regulation uncertainty. An increase in the cost of the environmental regulation moves a risk-averse firm closer to the output market. An augmented input or emission tax causes the risk-averse firm to locate closer to the output market. Uncertainty about environmental regulations in the form of the abatement investment and taxes also leads a risk-averse firm to locate closer to the output...

Oligopsony/Oligopoly Power and Factor Market Performance: The Case of U.S. Old Newspapers AgEcon
Hervani, Aref A..
This paper derives price-cost margins for the old newspaper (ONP) input market for newsprint manufacture and then examines the effects of two government policies and two variables measuring the market performances of ONP input and newsprint output on the oligopsonist’s ONP price-cost margins. In the wastepaper recycling market in particular, the ONP input market has not been successful in using the ONP generated. The outcomes of the study are that various degrees of price distortions existed in the ONP input markets in four regions of the United States during 1972-1995. Demand-side policy had a positive effect and supply-side policy had a negative effect on ONP price-cost margins in all regions.

Revenue-Recycling and the Efficiency and Spatial Distributional Impacts of Development Taxes AgEcon
Bento, Antonio M.; Franco, Sofia F.; Kaffine, Daniel T..
Recent studies that compare the efficiency and distributional impacts of alternative instruments to curb sprawl typically ignore what to do with the revenues from anti-sprawl policies, such as development taxes. This paper extends first-best analysis of development taxes aimed at preserving land at the urban fringe to account for interactions with other distortions within the urban system. By incorporating urban decline at the city core, which in turn, generates negative neighborhood spillover effects and extra pressure for development at the urban fringe, we provide a more complete framework to evaluate the efficiency and distributional impacts of development taxes. We consider three potential alternative schemes to recycle the revenues: lump sum...

TAX INCENTIVES: AN EFFECTIVE DEVELOPMENT STRATEGY FOR RURAL COMMUNITIES? AgEcon
Rainey, Daniel V.; McNamara, Kevin T..
As national and local economies become more globalized, many rural areas are going to find it more difficult to compete for private capital investments. A traditional tool, modifications to tax policy, of state and local governments will not be as effective (for many communities it has never been effective) in the future. These communities will need to seek other avenues of growth. However, for many rural communities even alternative avenues will not lead to enhanced economic opportunity.

THE ECONOMICS OF LAND-ZONING AgEcon
Goetz, Renan-Ulrich; Zilberman, David.
Land-use restrictions are frequently applied to separate polluting from non-polluting activities. In contrast to the existing literature, we incorporate spatial and intertemporal aspects of the problem simultaneously and determine the border of the zones endogenously. The results, based on a two-stage optimization method, show that non-spatially differentiated Pigouvian taxes on the final emissions are able to establish the socially optimal outcome. Second-best instruments alone, such as a spatially differentiated tax on inputs or outputs are not able to support the socially optimal outcome and need to be complemented by land-zoning or land-use taxes. We compare the efficiency of different spatial environmental policies such as land-use taxes or land...
