Contracting for Canola in the Great Plains States

Canola has become an important crop in the last decade in the United States. Production of canola is risky and competes with other crops that have varying risk reduction mechanisms. Processors develop and offer contracts with varying specifications that allow growers to reduce risk and attract canola production. In this study, preplant contracting strategies were evaluated in terms of risk and return for growers and processors. Alternative contracts include fixed‐price‐variety‐specific with and without act‐of‐God provisions, and an oil‐premium contract. Grower returns and processor gross margins were simulated and resulting distributions were evaluated using stochastic efficiency with respect to a function. In the dominant growing region, growers would prefer fixed‐price‐variety‐specific contracts versus contracts with oil premiums. The latter would only be preferred by crushers that are highly risk averse. The results vary regionally suggesting that contract types should vary by region to be acceptable to a broader range of growers and processors.     

A Growth Accounting Analysis of Cost Efficiency in Milk Production for Six Northern States in the United States

This paper reports on the use of a growth accounting approach to calculate and decompose cost efficiency indices into technical change, regional competitive advantage stemming from spatial effects, and economies of size. Dairy farm data for Connecticut, Maine, Vermont, Michigan, New York and Pennsylvania for the years 1968, 1970, 1977, 1980 and 1988 are utilized in the analysis. The results show that technological change yielded a 1.8% average annual rate of cost reduction over the period studied. In addition, medium and large farms were, on average, 12% to 20% more efficient than small farms. Pennsylvania had a distinct competitive advantage (13.8%), while Maine exhibited a clear competitive disadvantage (−18.2%) in producing milk relative to New York.     

Environmental Stewardship and Technical Efficiency in Canadian Prairie Canola Production

This study examines beneficial management practice (BMP) adoption and technical efficiency for canola producers in the Canadian Prairie Provinces. A Just‐Pope stochastic frontier production function is estimated using data from a survey of canola producers. Yield is modeled as a function of nutrients and precipitation. A linear inefficiency function includes farm specific variables and a set of binary variables representing BMP adoption. BMP variables for nutrient management planning and precision farming are positively related to technical efficiency while results for the other BMP indicators are mixed. Model estimates appear to be significantly influenced by moisture problems that occurred through the Prairie region during the 2011 cropping year. The study results suggest that for Western Canadian canola producers, there is potential complementarity for some BMPs in terms of improving technical efficiency while simultaneously advancing environmental stewardship.     

World Health Organization Dietary Norms: A Quantitative Evaluation of Potential Consumption Impacts in the United States, United Kingdom, and France

The member countries of the World Health Organization have endorsed its Global Strategy on Diet, Physical Activity, and Health. We assess the potential consumption impacts of these norms in the United States, France, and the United Kingdom using a mathematical programming approach. We find that adherence would involve large reductions in the consumption of fats and oils accompanying large rises in the consumption of fruits, vegetables, and cereal. Further, in the United Kingdom and the United States, but not France, sugar intakes would have to shrink considerably. Focusing on sub-populations within each country, we find that the least educated, not necessarily the poorest, would have to bear the highest burden of adjustment.     

The Potential for Increased Trade in Milk and Dairy Products between Canada and the United States under Trade Liberalization

Controversy surrounds the effect of free trade in milk and dairy products between Canada and the United States. A static, nonspatial, synthetic, partial equilibrium model is used to explore this issue. The results show that under any reasonable set of parameter estimates, net trade between Canada and the United States would be small, or zero. Free trade would be accompanied by large welfare losses for the current owners of Canadian milk production quota, but new entrants to the industry would earn more producer surplus under free trade than if they paid the full rental value for production quota under the current supply management policy.     

Away-from-Home and At-Home Beef Consumption in the United States

Logit models are developed to measure the effect of socioeconomic and demographic factors on the probability of consuming beef in the United States. The analyses are done in both the away from home and at home markets using the 1987-88 National Food Consumption Survey of the U.S. Department of Agriculture. Factors that significantly affect the likelihood of eating beef include: race, seasonality, urbanization, ethnicity, household size, sex, age, and income.     

Economics and Prescribed Fire Law in the United States

Prescribed burning is increasingly recognized as a useful but risky land management and conservation tool. Common law relating to prescribed fire is generally predicated on negligence rules. However, virtually all states also have statutory law specifying liability rules or criminal penalties for prescribed burning, and the laws in many states have been changing substantially in recent years. We develop an economic model of the incentive and welfare effects of prescribed burning, where both the burner and potential victims of escaped fires can reduce expected damage with precautionary effort. The model provides implications regarding the comparative advantages of strict liability versus negligence rules. We then examine the characteristics and geographic distribution of prescribed fire liability law in the United States in the context of the model. Specifically, we discuss possible economic underpinnings of the recent emergence of statutes in southeastern states that are more supportive of prescribed fire use, despite its associated risks.     

Consumer Welfare and the Livestock Economy in the United States

This paper analyzes the responsiveness of the U.S. meal and poultry economy to government policies and other exogenous shocks. In particular, it focuses on the measurement of changes to consumer welfare. An explicit econometric model represents the supply of fed beef, non-fed beef, pork, and poultry. The interaction between the livestock and feed grain markets is captured by an econometric model of the supply and demand for corn. Consumers are represented by a complete system of consumer demand equations. The model is used for a partial analysis of the welfare effects of an actual agricultural policy decision – the sale of large quantities of grains to the Soviet Union in the third quarter of 1972. The loss to consumers that is attributable to the increased grain exports did not reach its maximum until the second quarter of 1975. It is estimated that from 1973 to 1975 consumers suffered a reduction of meat consumption that they valued at $4.5 billion (U.S.). Furthermore, the effects of grain exports proved far larger than the losses due to the poor harvests of 1973 and 1974. Finally, attempts to shelter consumers from the effects of the increased corn exports, either by increased beef imports or increased grain price supports, would have had little success in compensating for the welfare loss actually suffered.

Employing resilience in the United States Forest Service

The concept of resilience has permeated the discourse of many land use and environmental agencies in an attempt to articulate how to develop and implement policies concerned with the social and ecological dimensions of natural disturbances. Several distinct definitions of resilience exist, each with its own concepts, focus and contexts related to land use policy and management. This often makes understanding the inherent objectives of policies and related principles challenging. The United States Forest Service (USFS) is one example where ambiguity and uncertainty surrounding the use of resilience permeates the content of documents in various areas of the agency. The objective of this paper is to investigate how the USFS employs the term resilience as a means to communicate strategies for managing forest lands. We perform a content analysis of 121 USFS documents including budgetary justification reports, research findings (i.e., journal articles, book chapters and technical reports), public releases, and newsletters to analyze both the rise and specific use of the term resilience in the USFS. Our analysis, which is guided by definitions of resilience in the social-ecological systems literature, reveals that the ambiguity surrounding the use of resilience in the academic literature is reflected in the content of USFS documents. However, we also find that often criticized versions of resilience (namely engineering resilience) are minimally employed by the USFS, and instead the agency focuses on the notion of ecological resilience in which natural disturbances are seen as an important component of the landscape. In some cases, the USFS employs notions of social-ecological resilience, however, the extent to which specific components of social-ecological resilience are integrated into management strategies appears minimal. The findings from this study suggest that clarity regarding the type and function of resilience needs to improve in USFS documents, and that the agency should evaluate the existing question in the SES literature of resilience of what to what?     

Assessing the Contribution of Genetic Enhancements and Fertilizer Application Regimes on Canola Yield and Production Risk in Manitoba

The number of canola varieties released, since the enactment of Plant Breeders' Rights (PBR) legislation in Canada in 1990, has increased substantively. The effect of genetic enhancements, including PBR, on canola yield and its variance is estimated for canola production regions of Manitoba using the Just‐Pope production function. Diagnostic tests reveal the presence of heteroscedasticity in the data. The percentage of varieties seeded with PBR has a negligible effect on canola yield. Hybrid and herbicide tolerant varieties (HY/HT) seeded on over 90% of canola production area increases average yield by about 6.8%. Increased spatial diversity (more varieties planted on fewer acres) has reduced canola yield by up to 1.7%. Temporal diversity (turnover of varieties) has no significant impact on yield. Nitrogen and sulphur fertilizers are yield increasing. The variance of yield is not impacted by PBR, HY/HT, other technology measures, or by fertilizer other than potassium. Canola breeding programs have not compromised canola yield stability. Depuis l'adoption de la Loi sur la protection des obtentions végétales (LPOV) au Canada en 1990, le nombre de variétés de canola mises au point a augmenté considérablement. L'effet des améliorations génétiques, y compris l'effet de la LPOV, sur le rendement du canola et sa variance a été estimé dans les régions du Manitoba productrices de canola à l'aide de la fonction de production Just‐Pope. Des tests de diagnostic ont révélé la présence d'hétéroscédasticité dans les données. Le pourcentage de variétés ensemencées depuis la LPOV a un effet négligeable sur le rendement de canola. Les variétés hybrides et les variétés tolérantes aux herbicides (HY‐HT) ensemencées sur plus de 90% des superficies cultivées en canola ont augmenté le rendement moyen d'environ 6.8%. L'accroissement de la diversité spatiale (plus de variétés sur moins de superficies) a diminué le rendement du canola jusqu'à 1.7%. La diversité temporelle (rotation des variétés) n'a aucun impact significatif sur le rendement. Les engrais azotés et soufrés augmentent les rendements. La variance du rendement n'est pas influencée par la LPOV, ni les HY‐HT, ni les autres mesures technologiques ni les engrais autres que le potassium. Les programmes de sélection du canola n'ont pas compromis la stabilité du rendement du canola.     

Effective Costs and Chemical Use in United States Agricultural Production: Using the Environment as a "Free" Input

A cost–function–based production model is used to represent patterns of input use and output production in U.S. agriculture, and the implied costs of induced reductions in risk from agricultural chemicals ("bad outputs"). We estimate and evaluate shadow values for these harmful outputs, and the implied input– and output–specific substitution patterns, with a focus on the impacts on pesticide demand and its quality and quantity components. Using state–level data we find these measures to be statistically significant, vary substantively by region, and imply increased demand for effective pesticides associated with improvements in quality from embodied technology.     

Demand Elasticities for Fresh Vegetables in the United States

Abstract

Demand elasticities at retail level for eight major fresh vegetables in the United States were estimated with the Almost Ideal Demand System using annual data over the period 1960-1993. Results show that the demand for fresh vegetables was generally inelastic with respect to changes in own prices, and cross-price effects for most fresh vegetables were negligible. Furthermore, the study suggests demands for carrots, cucumbers, lettuce, peppers, and onions were highly elastic with respect to changes in expenditures on fresh vegetables. However, expenditure elasticities for celery and tomatoes were found to be inelastic, while the expenditure elasticity for cabbages was negative but statistically insignificant.

Food Label Regulations in the United States and European Community:

Growing interdependence among the world's food markets presents increased trade and investment opportunities for food firms. Although international trade agreements have recently been negotiated which will likely lead to increased food trade, especially among Western nations, revised product standards and technical regulations used in the course of implementing these agreements have potential to create trade barriers that are less obvious. This paper assesses recent developments in food quality and labeling regulations in the European Community (EC) and United States. The regulatory changes taking place in these large trading partners have the potential to result in trade barriers based on meeting technical standards, especially since the reforms are being pursued independently in each country.
