Karen Smith is a senior fellow in the Income and Benefits Policy Center at the Urban Institute, where she is an internationally recognized expert in microsimulation. Over the past 30 years, she has developed microsimulation models for evaluating Social Security, pensions, taxation, wealth and savings, labor supply, charitable giving, health expenditure, student aid, and welfare reform. Smith has played a lead role in the development of the Social Security Administration's Modeling Income in the Near Term microsimulation model, Urban’s Dynamic Simulation of Income microsimulation model, and the Social Security Administration’s Policy Simulation Model. Her recent work includes estimating the impact of the Great Recession on retirement well-being; analyzing income and asset accumulation patterns of the adult population; analyzing the retirement decision; evaluating the effect of disability on earnings and mortality; and using statistical matching to impute earnings, taxes, and spouse characteristics.
