Professor Sims’ areas of expertise include the taxation of capital income (including timing issues and the taxation of financial instruments), wealth transfer taxation, federal tax policy (including structural aspects of the tax system), and the effects of tax policy on inequality. He has taught federal income taxation, taxation of financial instruments, taxation of corporations and shareholders, tax policy, law and economics, social scientific methods, and trusts and estates. His current research interests include the taxation of cancellation of indebtedness income, the income taxation of risk, aspects of the taxation of financial instruments, and the treatment of deferral in general. His past work includes studies of the structure of wealth transfer taxation and structural aspects of tax shelters, as well as theoretical and econometric work on the relationship between tax-motivated trading and stock market returns.

Professor Sims has taught courses in discounting and the taxation of debt in the NYU/IRS continuing legal education program, in connection with which he developed materials on discounting that integrate the study of the present value fundamentals with the implementation of present value in computer spreadsheets, and apply those methods to understanding the taxation of debt instruments. He has served as a consultant to the U.S. Treasury, has been a member of the American Law and Economics Association and is a member of the American Law Institute.
