Analysis of Factors Affecting Farmers’ Willingness to Adopt Switchgrass Production AgEcon
Qualls, D. Joshua; Jensen, Kimberly L.; English, Burton C.; Larson, James A.; Clark, Christopher D..
In the United States, biomass is the largest source of renewable energy accounting for over 3 percent of the energy consumed domestically and is currently the only source for liquid, renewable, transportation fuels. Continued development of biomass as a renewable energy source is being driven in large part by the Energy Independence and Security Act of 2007, which mandates that by 2022 at least 36 billion gallons of fuel ethanol be produced, with at least 16 billion gallons being derived from cellulose, hemi-cellulose, or lignin. However, the market for cellulosic biofuels is still under development. As such, little is known about producer response to feedstock prices paid for dedicated energy crops. While there have been some studies done on factors that...

Consumer Preferences for Refrigerators Manufactured by “Climate Leaders” AgEcon
Li, Xiaogu; Clark, Christopher D.; Jensen, Kimberly L.; Yen, Steven T..
In 2002, EPA established a voluntary program called the Climate Leaders Program (CL Program) designed for organizations to complete a corporate greenhouse gas (GHG) inventory, set a goal for reducing GHG emissions, and achieve that goal. The program was never implemented as a product labeling program. In 2010, EPA announced the program’s phase out. This study examines whether the CL Program could have been effectively used as a consumer product labeling program to assist consumers in choosing products manufactured by firms that have voluntarily set and achieved targeted GHG emission reductions.

Distance Education in Agricultural Economics: Perceptions of Department Heads AgEcon
Jensen, Kimberly L.; English, Burton C.; Clark, Christopher D..
Heads of agricultural economics and agribusiness departments across the United States are surveyed to develop an inventory of distance education (DE) offerings by their departments. Perceived challenges, strategies for use, and future plans for DE are assessed. While the majority of the responding departments offer DE, the department heads believed that faculty time costs to develop/deliver DE are high relative to traditional delivery and that both strategic plans for implementing DE and financial incentives for faculty to adopt DE are lacking. The department heads did, however, have positive views about the technological ability of students to use distance courses.

Dynamic Optimization of Fertilizer Application with Carryover and Runoff AgEcon
Zhou, Xia (Vivian); Clark, Christopher D.; Lambert, Dayton M..
The Economics of fertilizer application has been an interesting issue in regard to crop production (Kennedy et al., 1973). Understanding the temporal dynamics complicates the issue along two dimensions: fertilizer carryover and fertilizer runoff. Fertilizer carryover measures the amount of fertilizer applied in the previous period that is available for crops in current growing period (Kennedy et al., 1973). Fertilizer runoff refers to fertilizer leaving the ground and flowing into water bodies. Thus, the optimal quantity of fertilizer to be applied in the current period depends on the amount of previous application, runoff, and carryover. Because fertilizer carryover and runoff makes optimization of application a complicated intertemporal problem, static...

ECOLABELS AND ECONOMIC EFFICIENCY: SOME PRELIMINARY RESULTS AgEcon
Clark, Christopher D.; Russell, Clifford S..
The public provision of information about the environmental performance of firms and products has generated considerable enthusiasm and become a common instrument of environmental regulation, even though the economic analysis of the social welfare properties of these policies is quite limited. This paper proposes a model for examining these properties.

Factors Affecting Producer Participation in State-Sponsored Marketing Programs By Fruit and Vegetable Growers in Tennessee AgEcon
Davis, James A.; Velandia, Margarita M.; Clark, Christopher D.; Lambert, Dayton M.; Jensen, Kimberly L.; Wilcox, Michael D.; Wszelaki, Annette.
State programs promoting agricultural products have proliferated in response to increased consumer interest in locally grown foods. Tennessee, for example, currently has two state-sponsored programs promoting Tennessee agricultural products. This study examines the factors associated with fruit and vegetable farmer participation in these programs using mean comparisons and bivariate probit regression. Results suggest that farmer participation in these programs was associated with operation size, percentage of income from farming, percentage of annual sales from fresh produce, and attendance to University Extension educational events. These results should interest individuals attempting to increase producer participation in these types of programs.

Factors Influencing Consumer Likelihood of Purchasing a Flexible-Fuel or Hybrid Automobile AgEcon
Li, Xiaogu; Clark, Christopher D.; Jensen, Kimberly L.; English, Burton C.; Yen, Steven T..
Developing fuels and vehicles that reduce our reliance on fossil fuels has become a priority due to the threat of global climate change and desire for reduced dependence on oil imports. Flexible-fuel vehicles that can run on ethanol/gasoline blends of up to 85% ethanol and hybrid electric vehicles present two such opportunities. While production of both flexible-fuel and hybrid vehicles is increasing, there is still a great deal of uncertainty about how consumers will respond to these products. To address this uncertainty, data was collected through an online survey of automobile owners that asked respondents how likely they were to choose either a flexible-fuel or hybrid vehicle as their next vehicle. A bivariate probit model was used to jointly analyze...

Factors Influencing Willingness-to-Pay for the Energy Star Label AgEcon
Ward, David O.; Clark, Christopher D.; Jensen, Kimberly L.; Russell, Clifford S.; Yen, Steven T..
In the United States, nearly 17 percent of greenhouse gas emissions come from residential energy use. Increases in energy efficiency for the residential sector can generate significant energy savings and emissions reductions. Consumer labels, such as USEPA’s Energy Star, promote conservation by providing consumers with information on energy usage for household appliances. This study examines how the Energy Star label affects consumer preferences for refrigerators. An online survey of a national sample of adults suggest that consumers are, on average, willing to pay an extra $249.82 to $349.30 for a refrigerator that has been awarded the Energy Star label. Furthermore, the results provide evidence that willingness to pay was motivated by both private...

Farmer Willingness to Grow Switchgrass for Energy Production AgEcon
Jensen, Kimberly L.; Clark, Christopher D.; Ellis, Pamela; English, Burton C.; Menard, R. Jamey; Walsh, Marie E..
Increasing demand for the production of energy from renewable sources has fueled a search for alternatives to supplement those currently in production. One such alternative is switchgrass, a perennial grass native to North America that appears to have considerable potential as a biomass feedstock for energy production. While the properties of switchgrass as a biomass feedstock have been intensively studied, the potential market for switchgrass has received much less attention. A survey of Tennessee farmers was conducted to improve our understanding of those who might be willing to supply switchgrass to an emerging energy market. The results of this survey provide information on the willingness of Tennessee's agricultural producers to grow switchgrass as...

Projecting Spatial Pattern of Housing Growth in Tennessee AgEcon
Cho, Seong-Hoon; Clark, Christopher D.; Park, William M..
Housing growth in Tennessee that incorporates spatial spillover and spatial heterogeneity at the level of census-block group is projected. A deterministic interpolation technique is adopted to create alternative neighborhood variables that captures spatial spillover of neighborhood effects on housing growth without multicollinearity. The maps drawn using the geographically weighted regression parameter estimates revealed that the local marginal effect of the housing price increases on housing growth gradually increases as one moves eastward. The population growth in the adjacent neighborhood-block group has about 10% of marginal effect of population growth in its own block group. The marginal effect of population growth is relatively higher in the...

Spatial Analysis of Rural Economic Development Using a Locally Weighted Regression Model AgEcon
Cho, Seong-Hoon; Kim, Seung Gyu; Clark, Christopher D.; Park, William M..
This study uses locally weighted regression to identify county-level characteristics that serve as drivers of creative employment throughout the southern United States. We found that higher per capita income, greater infrastructure investments, and the rural nature of a county tended to promote creative employment density, while higher scores on a natural amenity index had the opposite effect. We were also able to identify and map clusters of rural counties where the marginal effects of these variables on creative employment density were greatest. These findings should help rural communities to promote creative employment growth as a means of furthering rural economic development.

Two Dimensions of the Spatial Distribution of Housing: Dependency and Heterogeneity across Tennessee’s Six Metropolitan Statistical Areas AgEcon
Cho, Seong-Hoon; Clark, Christopher D.; Park, William M..
A two-stage multinomial logit selection model is used to model the relationship between demographic characteristics and housing density across Tennessee’s six metropolitan statistical areas. The study finds that there is both spatial correlation and heterogeneity in the most densely populated area, has the least amount of spatial correlation among housing density at the neighborhood level, while Johnson City, which has the lowest overall housing density, has the highest degree of spatial correlation.

Willingness to Pay for Emission Reductions with E85 AgEcon
Jensen, Kimberly L.; Marra, Adrienne; Clark, Christopher D.; English, Burton C..
This study examines consumers' WTP for reductions in greenhouse gas emissions from E85 as opposed to gasoline. Data were collected via a contingent choice exercise in a 2009 national online survey. As part of the fuel choice exercise, several fuel attributes were allowed to vary including emission reductions, import level, proximity of fuel availability, price, and fuel blend (E85 or regular gasoline). A random parameters model with demographics and attitudes interacted with emission reductions was estimated. The resulting estimates suggest that, overall the WTP for an emission reduction is not statistically significant. However, for some demographic and attitudinal profiles, the WTP is significant. An example profile includes younger age, female,...
