The Emergence and Sustainability of Abnormal Profits

by Michael E. Porter and Anita M. McGahan

Abstract

In this paper, we examine the emergence and the sustainability of abnormal profits among businesses that were part of U.S. public corporations between 1981 and 1994 and that reported financial results for at least six years. Our results reveal strong asymmetries between high and low performers. Overall, high performance is more stable than low performance. High performers show profits above the average a decade earlier. In contrast, low performers show profits that are slightly above average a decade earlier. Industry and corporate-parent effects influence high performance to a far greater degree than low performance. Low performance is dominated by business-specific effects.

Since its establishment in 2005, Hamburg’s Martini Klinik had single-mindedly focused on prostate cancer care with a commitment to measure long term health outcomes for every patient. A wholly owned subsidiary of the University Hospital Hamburg, Martini Klinik was a “hospital in a hospital” in close proximity to other medical departments and services. By 2019, Martini Klinik had become the largest prostate cancer treatment program in the world with 8,000 outpatient cases and more than 2,500 surgical cases annually. Patients came from all over Germany and from around the world. A new and expanded facility was under construction to have the capacity to manage more patients with prostate cancer.

Cleveland Clinic: Transformation and Growth 2015

Michael E. Porter and Elizabeth O. Teisberg

The Cleveland Clinic's health care services are internationally renowned for quality. In 2008, The Clinic began to restructure the organization into teams defined around patient needs, rather than traditional medical specialties. "Patients First!" takes shape as the teams measure and report outcomes, coordinate care, and develop to support improving value for patients. In addition to restructuring care delivery in the hospitals and throughout northeastern Ohio, The Clinic has investments, facilities, and staff in several other states in the U.S. as well as in Canada and Abu Dhabi. Now in 2015, as the Clinic's domestic and international footprint continues to expand, its leadership is also focused in maintaining the Cleveland Clinic brand and providing optimal clinical care. Students can explore strategy transformation, geographic expansion, the process of introducing new measurement approaches, alignment of activities with strategic goals, and issues in leading change both within a company and across an economic sector.
