Kim Krawiec is the Charles O. Gregory Professor of Law, University of Virginia School of Law. Her current research analyzes “taboo trades” — exchanges that are contested by society and, in some cases, forbidden altogether. She has written on organ donation, commercial surrogacy, egg and sperm markets, and sex work. At the moment, much of her work is on incentives for organ donation. Although financial incentives are part of the menu, she is most interested in nonfinancial incentives, such as kidney swaps, NEAD chains, and priority systems that provide an incentive to donate.
