| The robustness of dynamic dual models examined by Howard and Shumway is reevaluated with the proper specification for the modified generalized Leontief (GL) and normalized quadratic (NQ) functional forms. In an application to the Northeastern and U.S. dairy industries, the theoretical properties, adjustment rates, and predictive ability were similar under both functional forms. However, elasticity measures differed significantly. |

| Inducing farmers to adopt alternative, more environmentally friendly production practices has been attempted in a variety of ways ranging from moral suasion to direct regulation to economic instruments. Among the most common instruments are voluntary cost-share programs that involve taxpayers sharing in the cost of production practices that generate fewer pollutants. These programs increase the attractiveness of alternative practices to farmers because they either compensate the farmer for any loss in profits or they offset the capital costs of adopting the new technology. Voluntary cost-share programs are a common policy tool because of their political viability, but their effectiveness has been limited largely due to the blanket approach used to... |

| The economic efficiency of cropping options to mitigate GHG emissions with agriculture in Eastern Canada was analyzed. Data on yield response to tillage (moldboard plow and chisel plow) and six corn based rotations were obtained from a 20-year field experiment in Ontario. Budgets were constructed for each cropping system while GHG emissions were measured for soil carbon and were estimated for nitrous oxide according to IPCC methodology. Complex crop rotations with legumes, such as corn-corn-soybeans-wheat with red clover underseeded, have higher net returns and substantially (more than 1 Mg ha1 year1) lower GHG emissions than continuous corn. Reduced tillage reduces GHG emissions due to lower input use but no sequestration effect could be found in the... |

| The objective of the 1997 Kyoto agreement was to limit greenhouse gas (GHG) emissions among signatory countries and thereby slow global warming. Under the agreement, Canada has committed itself to reduce GHGs over the next decade by 6 percent from estimated 1990 levels. Debate has now begun on the appropriate government policies that will induce the desired GHG reductions. Regulations could be in the form of direct controls or economic incentives, such as a subsidy/tax system or an emission trading system. The success of the U.S. emission market for SO2 (Schmalenseeet al., 1998) has generated growing interest in the use of a similar market mechanism for carbon (Holmes and Friedman, 2000). The existence of a carbon credit market presents the agricultural... |

| This study examines the extent to which farming practices have adjusted to the presence of urbanization in Canada. In particular, we compare the adoption rates for environmental management systems (EMSs) by farmers close to urbanized areas versus those in more rural, isolated regions. Using information from a national survey of 16,053 farmers, eight EMSs are considered. We find that farmers operating close to the urban milieu demonstrate strategic behavior by selecting more environmentally-friendly farm management practices to overcome social and regulatory pressures from such communities compared to those farmers that operate in rural communities. |

| Fundamental to the assertion that environmental regulatory standards are strategically set by decentralized authorities and consequently firms respond to spatial differences in regulatory standards is the underline causal relationship. Establishing the cause-effect association between regulatory standard setting and industry response is essential to justify the existence of the pollution haven and the potential for a race to the bottom. In this paper using 25 years data of the livestock production intensities for hog, dairy and fed cattle sectors and environmental regulatory stringency measure from 1975 to 2000 for 48 contiguous states we explore whether the direction of causality as suggested by race to the bottom hypothesis is in fact supported by the... |

| This report is an investigation of the financial feasibility of farm based anaerobic digestion investments under Ontario's Standard Offer Contract electricity prices. Using Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) Agricultural Anaerobic Digestion Calculation Spreadsheet (AADCS) anaerobic digestion inputs, outputs, cost and revenues were estimated and used to conduct a financial analysis on the feasibility of four sized farm base anaerobic digestion investments. The results suggest investment in an anaerobic digestion system smaller than 300 kilo-watts is not financially feasible under the chosen base model assumptions and Ontario's Standard Offer Contract. The efficiency of the anaerobic digestion systems,discussed in the report as... |

| Although differences in environmental stringency have been given as a reason for the growth of the livestock sectors, particularly hogs, in non-traditional production regions, there is little empirical evidence to support the existence of pollution havens. This paper uses the number of large farm as the dependent variable instead of state-level inventory data and also develops an environmental regulatory stringency measure for each state over approximately a decade and carries out a rigorous panel data analysis. After controlling for all other important location determinants, we find that stringent environmental regulations are one of the most important repellents of large hog farms in the United States. |

| The paper addresses the relationship between agricultural spills and environmental complaints filed by citizens against agriculture. It also determines the influence of other factors on the likelihood of both farm spills and complaints within a region. The relationships have been estimated using a unique data set containing the number of spills and complaints along with regional data such as the stringency of environmental regulations and socio-economic variables. Different environmental regulations do appear to have an effect on the spills and complaints. By-laws on the size of manure storage facility in relation to the number of livestock housed influence the likelihood of spills within a region. Larger storages decrease the number of annual manure... |

| Best management practices (BMPs) for cropping systems that involve conservation tillage and nutrient management are proposed as potential win-win solutions for both farmers and the environment. While originally targeted as a means for improving soil and water quality, these BMPs may also contribute to the mitigation of greenhouse gases (GHGs). Mitigation efforts have focused primarily on the ability of BMPs to sequester carbon and the subsequent potential revenue source carbon sequestration may represent to farmers. Increasingly, evidence from experimental stations calls into question the potential for C-sequestration with reduced tillage in soils in Eastern Canada. However, there are other ways in which BMPs can reduce GHG emissions: lowering fuel and... |

| A stochastic dynamic programming model is developed to determine optimal replacement intervals and depreciation schedules for a combine on a cash grain farm in north central Montana, where the optimal decision is based on the stochastic nature of winter wheat prices. Empirical results indicate that the decision varies widely depending on the states describing the conditions facing the farm firm. Under normal profitable conditions and ERTA81 tax legislation, suggested replacement is after five years of service, the new asset being depreciated under the accelerated cost recovery system and the investment credit option. Changes to the tax law would tend to smooth out and increase this replacement interval. |
