Item All plug-in electric vehicles are not the same: Predictors of preference for a plug-in hybrid versus a battery-electric vehicle(Elsevier, 2018-12) Lane, Bradley W.; Dumortier, Jerome; Carley, Sanya; Siddiki, Saba; Clark-Sutton, Kyle; Graham, John D.; School of Public and Environmental AffairsThis study analyzes data from a survey of drivers (n = 1080) administered in late 2013 to assess factors that influence potential car buyers to consider two different types of plug-in electric vehicles (PEVs) in the United States: plug-in hybrid electric vehicles (PHEVs) and battery electric vehicles (BEVs). The results indicate distinct profiles of respondents preferring PHEVs, which have a gasoline backup engine, versus battery BEVs, which rely solely on a battery for power. Respondents interested in selecting a PHEV consider it more for its economic benefits, such as reduced gasoline and maintenance expenditures. Respondents preferring a BEV are drawn to its environmental and technological appeal. The absence of range anxiety for PHEV is a major factor influencing potential PEV buyers.Item Changes in Fuel Tax Policy and the Impact on State and Federal Revenue(2014-03) Dumortier, Jerome; Marron, John; Zhang, FengxiuItem China-U.S. trade dispute and its impact on global agricultural markets, the U.S. economy, and greenhouse gas emissions(Wiley, 2021) Elobeid, Amani; Carriquiry, Miguel; Dumortier, Jerome; Swenson, David; Hayes, Dermot J.; School of Public and Environmental AffairsChina is a major importer of agricultural products and we examine retaliatory tariffs imposed by China on U.S. pork, soybeans, corn, and wheat. We use an agricultural trade model to determine the impacts on agricultural commodity markets and combine our results with an input-output model to measure economic effects in the United States. In addition, we calculate global greenhouse gas (GHG) emissions from land-use change. The consequences of retaliatory tariffs are both trade destruction (lower overall trade) and trade diversion (trade diverted away from the U.S. and to other exporting countries). By the end of the projection period, total U.S. pork exports decline by 4.7%. Total soybean and wheat exports decrease by 31.2% and 0.5%, respectively whereas corn exports increases by 4.0%. Domestic U.S. retail pork prices decline by 0.8% and commodity farm prices decrease by 4.2%, 5.1%, and 15.8% for corn, wheat, and soybeans, respectively. The decline in foreign demand reduces U.S. production and welfare. Key among these impacts are a loss of nearly 15,400 jobs and a fall in labor income by $1.35 billion due to a $3.70 billion decline in national output at the beginning of the projection period. By the last year of the projection, the impacts grow to almost 30,000 fewer jobs and $2.31 billion less labor income. The U.S. economy experiences a loss of slightly under $6.80 billion in national output. Changes in trade due to the tariffs result in a reduction of GHG emissions from land-use change of up to 83.7 teragram (Tg) of CO2-equivalent.Item Co-firing in coal power plants and its impact on biomass feedstock availability(2014-03) Dumortier, JeromeItem Co-firing in coal power plants and its impact on biomass feedstock availability(2014-03) Dumortier, JeromeItem Co-firing in Coal Power Plants and its Impact on Biomass Feedstock Availability(Elsevier, 2013-09) Dumortier, Jerome; School of Public and Environmental AffairsSeveral states have a renewable portfolio standard (RPS) and allow for biomass co-firing to meet the RPS requirements. In addition, a federal renewable fuel standard (RFS) mandates an increase in cellulosic ethanol production over the next decade. This paper quantifies the effects on local biomass supply and demand of different co-firing policies imposed on 398 existing coal-fired power plants. Our model indicates which counties are most likely to be able to sustain cellulosic ethanol plants in addition to co-firing electric utilities. The simulation incorporates the county-level biomass market of corn stover, wheat straw, switchgrass, and forest residues as well as endogenous crop prices. Our scenarios indicate that there is sufficient feedstock availability in Southern Minnesota, Iowa, and Central Illinois. Significant supply shortages are observed in Eastern Ohio, Western Pennsylvania, and the tri-state area of Illinois, Indiana, and Kentucky which are characterized by a high density of coal-fired power plants with high energy output.Item Effects of Life Cycle Cost Information Disclosure on the Purchase Decision of Hybrid and Plug-In Vehicles(2014-06) Dumortier, Jerome; Siddiki, Saba; Carley, Sanya; Cisney, Joshua; Krause, Rachel M.; Lane, Bradley W.; Rupp, John A.; Graham, John D.Item Effects of Life Cycle Cost Information Disclosure on the Purchase Decision of Hybrid and Plug-In Vehicles(Elsevier, 2015-02) Dumortier, Jerome; Siddiki, Saba; Carley, Sanya; Cisney, Joshua; Krause, Rachel M.; Lane, Bradley W.; Rupp, John A.; Graham, John D.; School of Public and Environmental AffairsEnergy-saving technologies have a difficult time being widely accepted in the marketplace when they have a high initial purchase price and deferred financial benefits. Consumers might not realize that, in the long-run, the financial benefits from reduced energy consumption offset much or all of the initial price premium. One strategy to address consumer misconception of this advantage is to supply information on the “total cost of ownership”, a metric which accounts for the purchase price, the cost of the fuel, and other costs over the ownership period. In this article, we investigate how providing information on five-year fuel cost savings and total cost of ownership affects the stated preferences of consumers to purchase a gasoline, conventional hybrid, plug-in hybrid, or battery electric vehicle. Through an online survey with an embedded experimental design using distinct labels, we find that respondent rankings of vehicles are unaffected by information on five-year fuel cost savings. However, adding information about total cost of ownership increases the probability that small/mid-sized car consumers express a preference to acquire a conventional hybrid, plug-in hybrid, or a battery-electric vehicle. No such effect is found for consumers of small sport utility vehicles. Our results are consistent with other findings in the behavioral economics literature and suggest that further evaluation of the effects of providing consumers with information on the total cost of vehicle ownership is warranted.Item The effects of potential changes in United States beef production on global grazing systems and greenhouse gas emissions(Office of the Vice Chancellor for Research, 2013-04-05) Dumortier, Jerome; Hayes, Dermot J.; Carriquiry, Miguel; Dong, Fengzia; Du, Xiaodong; Elobeid, Amani; Fabiosa, Jacinto F.; Martin, Pamela A.; Mulik, KrantiWith climate change becoming an increasingly pressing issue together with a world population of 7 billion people in 2011, significant pressure is put on global agriculture and forestry. Although treated separately in national GHG inventories, there is little doubt that both categories are closely linked and climate policies targeting agriculture will have spillover effects on forestry and vice versa. Hence, the implementation of large-scale agricultural policies is prone to unintended consequences. For this poster, we analyze the hypothesis that a reduction of cattle in the U.S. causes a net increase in GHG emissions on a global scale. We couple a global agricultural production and trade model with a greenhouse gas model to assess leakage associated with modified beef production in the United States. The effects on emissions from agricultural production (i.e., methane and nitrous oxide emissions from livestock and crop management) as well as from land-use change, especially grazing system, are assessed. We find that a reduction of U.S. beef production induces net carbon emissions from global land-use change ranging from 37 to 85 kg CO2-equivalent per kg of beef annualized over 20 years. The increase in emissions is caused by an inelastic domestic demand as well as more land-intensive cattle production systems internationally. Changes in livestock production systems such as increasing stocking rate could partially offset emission increases from pasture expansion. In addition, net emissions from enteric fermentation increase because methane emissions per kilogram of beef tend to be higher globally.Item Effects of providing total cost of ownership information on consumers’ intent to purchase a hybrid or plug-in electric vehicle(Elsevier, 2015-02) Dumortier, Jerome; Siddiki, Saba; Carley, Sanya; Cisney, Joshua; Krause, Rachel M.; Lane, Bradley W.; Rupp, John A.; Graham, John D.; School of Public and Environmental AffairsEnergy-saving technologies have a difficult time being widely accepted in the marketplace when they have a high initial purchase price and deferred financial benefits.
