Cox has conducted research on integration of portfolio choice and consumer demand theories, public expenditure theory, credit rationing, energy policy, economics and political economics of minimum wage legislation, auction markets, job search models, decentralized mechanisms for control of monopoly. Also, the utility hypothesis, the preference reversal phenomenon, procurement contracting, the lottery payoff experimental procedure, topics in social epistemology and legal theory, and group vs. individual behavior in strategic market games and fairness games, and e-commerce with combinatorial demands. His research includes work on theoretical modeling and laboratory experiments with: trust, reciprocity and altruism; small- and large-stakes risk aversion; public goods and common pool resources; and centipede games vs. Dutch auctions.
Collaborative research with surgeons is in progress on improving hospital discharge decision-making and analysis of decision-making for human organ rejections or acceptances for transplantation. Cox’s work has been funded by the National Science Foundation, National Institutes of Health and other research support institutions.
Sadiraj is involved in research programs in public choice, public economics, individual social preferences and decision theory. She is interested in theoretical modeling and experimental testing of the theory. Her projects include emergence and role of interests groups in spatial models of electoral competition, effects of rotation schemes on committee performance, effects of benefit taxation and ability to pay on excess burden, theoretical modeling of social preferences, conditional and unconditional altruism, individual risk aversion in small and large stakes.
Swarthout’s research interests involve experimental economics, game theory, and auctions. Recent projects have focused on: alternative forms of procurement auctions, public goods mechanisms and using human interaction with computerized algorithms to better understand strategic behavior in games. He is also involved in developing software technology for instructional games and activities in economic education.
Harrison is involved research work using experimental economics to study the behavior of bidding in auctions, market contestability and regulation, bargaining behavior and the elicitation of risk and time preferences. Most recently he has examined the complementarity of laboratory and field experiments. His work in law and economics has centered on the calculation of compensatory damages in tobacco litigation, including testifying for plaintiffs in the Medicaid litigation that resulted in a settlement worth more than $200 billion.
Laury uses experimental methods to address a wide range of economic issues. Her research includes investigating individual attitudes toward risks involving gains and losses as well as how the presence of insurance markets and the types of insurance policies offered affect decisions in risky environments. She is also interested in exploring how other-regarding behavior affects decision-making. She uses experiments in the classroom and has co-authored papers that describe classroom games. Her research has been published in journals such as American Economic Review, Journal of Public Economics and Public Choice.
Carattini studies energy and environmental policy, behavioral economics, public economics and political economy. His research combines policy evaluation, to examine how policies work, with empirical analyses of their political economy. He has also been working on cooperative (pro-social) behavior and the diffusion of green behaviors, practices and technologies.
