    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 Affairs
    This 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.

    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 Affairs
    Energy-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.

    Effects of providing total cost of ownership information on consumers’ intent to purchase a hybrid or plug-in electric vehicle

    Exploring the Relationship between Hazard Adjustments and Risk Managers in Organizations
    (Wiley, 2016-12) Sadiq, Abdul-Akeem; Graham, John D.; School of Public and Environmental Affairs
    There is little empirical evidence on the relationship between organizational risk managers and the adoption of hazard adjustments (measures taken to reduce risks from extreme events). Similarly, the risk perception literature is mixed on the relationship between risk perception and the adoption of hazard adjustments in organizations. This study empirically addresses these two gaps using data collected from 227 public, private and non-profit organizations in the Memphis/Shelby County area, Tennessee, in 2006. This study finds a significant positive relationship between risk managers and the adoption of hazard adjustments. The results also indicate that organizational risk perception has a small positive influence on the adoption of hazard adjustments.

    FEMA versus local governments: Influence and reliance in disaster preparedness
    (Springer, 2016) Sadiq, Abdul-Akeem; Tharp, Kevin; Graham, John D.; School of Public and Environmental Affairs, IUPUI
    This study uses an experimental approach to examine whether disaster information sourced to the Federal Emergency Management Agency (FEMA) influences intentions to adopt hazard adjustments. Survey questions are also used to determine whether individuals rely more on FEMA or local governments when preparing for disasters. Using an online sample of 2008 US employees, the results indicate that information sourced to FEMA is no more influential than information sourced to local governments and that individuals rely less on FEMA than on local agencies during disaster preparedness. These results have significant implications for practice and future research on natural hazard preparedness.

    Organizational Risk Perception of Disasters: Do Risk Managers Matter?
    (Harvard Center for Risk Analysis, 2014-03-20) Sadiq, Abdul-Akeem; Graham, John D.
    Previous research on risk perception suggests that individual neglect of disasters is likely due to an inability to process information about low-probability, high-consequence threats and moral hazard. As a result, it is important to study the quality of organizational responses to disasters, since they may be crucial to compensating for the frailty of individual choice. Preliminary evidence suggests that an organizational risk manager is important in disaster planning, but there is no empirical evidence (to our knowledge) that having a designated risk manager leads to the adoption of risk-reducing measures in organizations. Additionally, there is limited research on the relationship between risk perception and the adoption of risk-reducing measures at the organizational level. The goal of this study is to empirically answer two questions. (1) “Does having a risk manager in an organization predict the adoption of risk-reducing measures?” (2) “What is the relationship between risk perception and the adoption of risk-reducing measures at the organizational level?” Using data collected from a sample of public, private, and non-profit organizations in the Memphis/Shelby County area, Tennessee in 2006, we find that organizations with risk managers adopted more risk-reducing measures than organizations without risk managers and that risk perception is a significant predictor of risk-reducing measures. This study builds on a small, but growing literature on how organizations perceive risks and respond to them.
