Frederick Solt is Professor in the Department of Political Science at the University of Iowa. He is author and maintainer of the DCPOtools
package and the founder of the DCPO Lab. His other interests include comparative political behavior and political economy from a cross-national perspective. Much of his work focuses on understanding how—and why—the extent of economic inequality in a country shapes the attitudes and behavior of the people who live there. He also created and maintains the Standardized World Income Inequality Database (SWIID), which provides the most-comparable data available on income inequality for broadly cross-national research.
