Professional Bio

Professor Siebert joined the Krannert School of Management at Purdue University in January 2004. He is also an Adjunct Visiting Associate Professor at the  University of Chicago (Booth School of Business).

Professor Siebert is working in the areas of industrial organization, applied microeconometrics, urban economics, health economics, and experimental economics. Most of his research is grounded in the interface between applied theory and empirical testing, i.e., structural modeling, while other studies relate to reduced-form regressions and applied theory. The large majority of his empirical work builds on theory that provides insights into counterfactuals, as well as underlying effects that drive the results.

Professor Siebert's research studies investigate the competitiveness of firms and market performance accounting for dynamic strategic interactions between firms. His work frequently focuses on policy-relevant topics to provide insights for antitrust and competition policy. One of the main methodological characteristics of his research is that it often goes beyond a static evaluation approach and emphasizes firm and industry dynamics. He devotes special attention to the interlink between technology and product market competition. His areas of expertise include various markets within the semiconductor industry, such as SRAM, DRAM, and flash memories, as well as the pharmaceutical industry, the housing market, and the health market.

Professor Siebert's studies primarily focus on the following topics: strategic alliances (mergers, joint ventures, licensing) multi-product competition and product differentiation, innovation, industry and firm dynamics (evolution of industries, learning by doing) and obesity. 

Professor Siebert has various publications in top economics and general interest journals. 

Professor Siebert was a (Visiting) Associate Professor at the University of Chicago, Harvard University, Yale University, University of Toronto, Ludwig Maximilians University (Munich, Germany), Center for Economic Studies (Munich, Germany), Social Science Research Institute (WZB, Germany), European School of Management and Technology (Berlin, Germany), and Humboldt-University (Berlin, Germany).

In 2011, Professor Siebert received the Young Scholar Award from Purdue University (Krannert School of Management). He also received awards as a distinguished teacher every year from 2005 onwards. He won the European Young Economist Award in two consecutive years, i.e., 2000 and 2001.
