    Dealing with Missing Data: A Comparative Exploration of Approaches Using the Integrated City Sustainability Database
    (Sage, 2017) Curley, Cali; Krause, Rachel M.; Feiock, Richard; Hawkins, Christopher V.; School of Public and Environmental Affairs
    Studies of governments and local organizations using survey data have played a critical role in the development of urban studies and related disciplines. However, missing data pose a daunting challenge for this research. This article seeks to raise awareness about the treatment of missing data in urban studies research by comparing and evaluating three commonly used approaches to deal with missing data—listwise deletion, single imputation, and multiple imputation. Comparative analyses illustrate the relative performance of these approaches using the second-generation Integrated City Sustainability Database (ICSD). The results demonstrate the benefit of using an approach to missing data based on multiple imputation, using a theoretically informed and statistically supported set of predictor variables to develop a more complete sample that is free of issues raised by nonresponse in survey data. The results confirm the usefulness of the ICSD in the study of environmental and sustainability and other policy in U.S. cities. We conclude with a discussion of results and provide a set of recommendations for urban researcher scholars.

    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
