Stephen T. Ziliak is Professor of Economics at Roosevelt University, Chicago, where as a faculty member he served on the Board of Trustees (from 2010 to 2013); he is also a Faculty Member of The Angiogenesis Foundation (Cambridge, MA). His previous appointments include Emory University and the Georgia Institute of Technology, where he was voted Faculty Member of the Year  (in 2002) and Most Intellectual Professor (in 2003).  At the University of Iowa he earned (in 1996) the Ph.D. in Economics and, at the same time, the Ph.D. Certificate in the Rhetoric of the Human Sciences.  He has been a Visiting Professor of Economics, Statistics, Rhetoric, Justice, Social Welfare, and Methodology at leading universities of the United States, Belgium, Denmark, England, France, Turkey, and the Netherlands.

Ziliak’s early work was on econometric methodology and quantitative economic history, where he established himself as a leading economic historian of welfare and charity in the United States.  He, at the same time, published a seminal article of econometrics, “The Standard Error of Regressions” (1996, with Deirdre N. McCloskey), prior to tackling the history, philosophy, and practice of all the testing sciences.

His pioneering contributions to the seemingly disparate fields of economic statistics and poetry include Guinnessometrics, the cult of statistical significance, haiku economics, renganomics, and economics rap. His research has appeared in many leading journals, such as The Lancet, Journal of Economic Literature, Journal of Economic Perspectives, Poetry, Biological Theory, International Journal of Forecasting, Journal of Economic History, and Journal of Wine Economics.

He is the lead author of The Cult of Statistical Significance: How the Standard Error Costs Us Jobs, Justice, and Lives (2008) a best-selling and critically-acclaimed book at the University of Michigan Press, with Deirdre N. McCloskey; with McCloskey and Arjo Klamer he is co-author of The Economic Conversation, an evolving textbook and blog, emphasizing dialogue and openness; and he edited and contributed to Measurement and Meaning in Economics: The Essential Deirdre McCloskey (Edward Elgar, 2001). An Associate Editor of Historical Statistics of the United States (Cambridge, 2006), Ziliak’s work has been featured in Science, Nature, The Economist, Poetry, Wall Street Journal, BBC, NPR, Inside Higher Ed, Chronicle of Higher Education, National Review, Slate, Salon, Washington Post, Financial Times, New York Times, and the Supreme Court of the United States.
