Can Faculty Change Initial Impressions on Student Evaluations of Teaching? AgEcon
Pruitt, J. Ross; Dicks, Michael R.; Tilley, Daniel S..
Expectations of a course and instructor are formed prior to engagement in the course which affect learning. By understanding the factors that are involved in setting these expectations, instruction and student learning may be improved. This paper seeks to determine if student expectations set the basis for course and instructor appraisal and what factors affect these expectations or changes from expectations. Results indicate that while instructor appraisal does not change over the course of the semester, variables related to instructor appraisal do change. How worthwhile students view the course can also positively or negatively impact overall course appraisal.

Impact of United States Corn-Based Ethanol Production on Land Use AgEcon
Sobowale, Flakkeh; Dicks, Michael R.; Adam, Brian D.; Campiche, Jody L..
This study measures the impact of corn-based ethanol production in the United States on land use in other countries, or indirect land use. Indirect land use is a change from non-cropland to cropland (e.g. deforestation) that may occur in response to increasing scarcity of cropland. As farmers worldwide respond to higher crop prices in order to maintain the global food supply and demand balance, pristine lands are cleared and converted to new cropland to replace the crops for feed and food that were diverted elsewhere to biofuel production. The results show that increasing ethanol production in the US has a positive and significant relation to U.S corn price. However, U.S. corn price does not have a significant impact on changes in corn acreage in Brazil...

Impact of United States Corn-based Ethanol Production on Land Use AgEcon
Sobowale, Folakemi; Dicks, Michael R.; Campiche, Jody L..
The purpose of this research was to determine whether indirect land use occurs and if so to what extent. Indirect land use is a change from non-cropland to cropland (e.g. deforestation) that may occur in response to increasing scarcity of cropland. As farmers worldwide respond to higher crop prices in order to maintain the global food supply and demand balance, pristine lands are cleared and converted to new cropland to replace the crops for feed and food that were diverted elsewhere to biofuels production. We examine the impact of corn-based ethanol production in the United States on land use in other countries.

What is the Difference in Profit per Acre between Organic and Conventional Coffee? AgEcon
Jensen, Jennifer; Dicks, Michael R..
The research addresses the economic problem of deforestation. A contributing factor to deforestation is coffee production. Coffee is an indigenous plant that is naturally occurring in the native tropical forests. However, conventional coffee is grown on cleared forest soil. In the native forest there is the potential for additional fruits (bananas, mangoes, avocados) and wood products while in the conventional coffee production system the only product is coffee. Conventional coffee production often causes deforestation and soil erosion while the organic coffee production system does not. In addition, the price risk associated with the coffee monoculture is high and has proven disastrous to the sustainability of coffee production in past years. Thus,...

Fertilizer Demand for Biofuel and Cereal crop Production in the United States AgEcon
Acheampong, Kwame; Dicks, Michael R..
The emergence of biofuel production has impacted almost all sectors of the agricultural industry and the general economy and has produced a large body of research into how increased production of biofuels will impact the agricultural sector and the general economy. All research is in agreement that total biomass production will be required to increase to meet food and fuel demands. The increase in biomass will, of necessity, require increased use of fertilizers. Research on fertilizer demand has been scarce over the last decade. Because of the recent increase in the demand for grain crops and livestock in an era with little excess capacity in commodity production, the pressure to increase output will fall to increased use of fertilizers. In addition,...

Spatial Differences of Land Use Change within Oklahoma's Wheat Belt AgEcon
Leonard, J. Mark; Dicks, Michael R.; Richter, Francisca G.-C..
Farm Service Agency acreage data for the nine Oklahoma Agricultural Statistics Service districts is analyzed to determine the degree of price response in wheat acreage allocation decisions. Some critics have stated that land use after Freedom to Farm would change little, however these findings show acreage shifted greatly after the policy throughout the state.

Potential Economic Impacts of the Managed Haying and Grazing Provision of CRP AgEcon
Dickson, Amanda; Dicks, Michael R..
According to the Executive Order 12866, a qualitative and quantitative assessment for any Federal mandate resulting in annual expenditures of $100 million or more is required. This study determines how many of the approximately 34.5 million acres of CRP land is brought back in economic use, how that use is allocated between grazing and haying, and the economic impact.

Land Use Implications of Expanding Biofuel Demand AgEcon
Dicks, Michael R.; Campiche, Jody L.; Torre Ugarte, Daniel de la; Hellwinckel, Chad M.; Bryant, Henry L.; Richardson, James W..
The Renewable Fuel Standard mandates in the Energy Independence and Security Act of 2007 will require 36 billion gallons of ethanol to be produced in 2022. The mandates require that 16 of the 36 billion gallons must be produced from cellulosic feedstocks. The potential land use implications resulting from these mandates were examined using two methods, the POLYSYS model and a general equilibrium model. Results of the POLYSYS analysis indicated that 72.1 million tons of corn stover, 23.5 million tons of wheat straw, and 24.7 million acres would be used to produce 109 million tons of switchgrass in 2025 to meet the mandate. Results of the CGE analysis indicated that 10.9 billion bushels of corn grain, 71 million tons of corn stover, and 56,200 tons of...

Recent Developments in Unit Root Tests and Historical Crop Yields AgEcon
Zapata, Hector O.; Maradiaga, David Isaias; Pujula, Aude Liliana; Dicks, Michael R..
This study conducts an investigation on the application of classical unit-root tests using parametric tests (the augmented Dickey-Fuller, 1979 – ADF), and nonparametric tests (Phillips and Perron, 1988—PP) to corn and soybean yields in the Delta states using county-level data from 1961 to 2009. The main concern of the paper is to assess what would be drawn about nonstationarity in crop yields using these tests versus using modified versions of these tests (Ng and Perron, 2001) that are assumed to solve size and power problems associated with the ADF and PP tests. The investigation focuses on methodological aspects of the classical tests, uncovers the nature of filtered yields often needed prior to density estimation, sheds light on the effect of lag...

THE EFFECTS OF COMMODITY PROGRAM PARTICIPATION ON BIDDING N THE CONSERVATION RESERVE PROGRAM AgEcon
Riely, Patricia L.; Dicks, Michael R.; Shagam, Shayle D..
An analysis of Conservation Reserve Program contracts obtained during the 1986 sign-up periods indicates commodity program participants enrolled more acreage at higher costs than farmers not participating in other commodity programs. Significant differences also occurred between the various commodity program crops, reflecting the difference in benefits available for these crops.

The Impact of Biofuel Mandates and Switchgrass Production on Hay Markets AgEcon
Acheampong, Kwame; Dicks, Michael R.; Adam, Brian D..
The Renewable Fuel Standard mandate in the Energy Independence and Security Act of 2007 requires 16 billion gallons out of 36 billion gallons of ethanol be produced from cellulosic feedstocks in 2022, but the mandate was apparently enacted without critical assessments of the agricultural impacts of attempting to achieve energy independence. The feedstock production will likely compete with lands currently used for producing other traditional crops of which hay is likely to be affected the most since it has comparatively lower net returns. Thus ruminant production will consequently be affected greatly. This study uses ordinary least squares (OLS) to estimate and predict Oklahoma hay price which is used as objective value in linear programming (LP) model...

REGIONAL ADJUSTMENT COSTS: A FAILURE OF NATIONAL ANALYSIS AgEcon
Dicks, Michael R..
The use of national aggregate measures for the purpose of analyzing the impacts of agricultural policies hides the impact of national policies on the distribution of benefits and costs between and within regions, size, and types of businesses. While economists can use national aggregate measures to indicate changes in overall efficiency due to policies, the tradeoff between efficiency and equity should be measured and the results provided to policymakers. These tradeoffs were not presented during the 1995-96 Farm Bill debate.

Potential Economic Impacts of the Managed Haying and Grazing Provision of the Conservation Reserve Program AgEcon
Campiche, Jody L.; Dicks, Michael R.; Shideler, David W.; Dickson, Amanda.
The Food Security and Rural Investment Act of 2002 included a new provision that allowed managed haying and grazing (including the harvest of biomass), if consistent with the conservation of soil, water quality, and wildlife habitat, in return for partial reductions in the annual CRP payments. The legislation provided for managed (or limited use) haying and grazing on the CRP acreage rather than prohibiting all use. This research analyzed whether or not the alternative grazing and haying scenarios would dramatically impact the price of beef or hay, and we estimated the impact such changes would have on state economies.

ESTIMATING THE IMPACT OF CONSERVATION RESERVE PROGRAM CONTRACT EXPIRATION ON CORN AND WHEAT PRICES AgEcon
Garrison, Carl O.; Dicks, Michael R.; Adam, Brian D..
The Conservation Reserve Program reduced available cropland in the United States by 34 million acres under the first nine signup periods (1986-1990). Among these are ten million acres with wheat base and four million acres with corn base, which could potentially produce 288 million bushels of wheat and 340 million bushels of corn per year upon contract expiration. The impacts of expiring CRP contacts on the production and prices of wheat and corn in the United States are estimated. Based on past production practices and post-CRP land-use intentions of contract holders, 48.2% of base acres enrolled in CRP will return to production. Under this scenario, wheat prices will decline by more than 7% and corn prices by more than 2% by 2000, unless ARP levels,...
