Richard S. Ruback's research and course development focus on applied corporate finance-in particular, corporate control transactions and valuation. His research on corporate control has yielded case studies on major transactions, such as the RJR Nabisco
leveraged buyout, and their consequences (examined in a three-case series on Southland Corporation,
owner of the 7-Eleven convenience-store chain). It includes a study (with Paul Healy and Krishna G. Palepu) that examines the postmerger performance and determinants of the long-term financial success of large merged firms. Ruback's work on valuation has produced a series of cases that highlight effective valuation tools and the consequences of their use. It includes a study (with Steven Kaplan) of how cash flow forecasts are valued in capital markets.
