Matthew Ringgenberg is a fourth year PhD student in Finance. His research focuses on equity lending, short selling, commodity markets, and information economics.
His research on equity lending and short selling examines the causes and results of short selling constraints in opaque markets in order to understand how and when short selling constraints arise. In addition, he has examined whether or not idiosyncratic risk matters when short-sale constraints are present.
Prior to entering the PhD program, Mr. Ringgenberg worked as a consultant for Charles River Associates in Chicago.
