Schumpeterian Competition and Diseconomies of Scope: Illustrations from the Histories of Microsoft and IBM

by Timothy F. Bresnahan, Shane Greenstein and Rebecca M. Henderson

Abstract

We address a longstanding question about the causes of creative destruction. Dominant incumbent firms, long successful in an existing technology, are often much less successful in new technological eras. This is puzzling, since a cursory analysis would suggest that incumbent firms have the potential to take advantage of economies of scope across new and old lines of business and, if economies of scope are unavailable, to simply reproduce entrant behavior by creating a "firm within a firm." There are two broad streams of explanation for incumbent failure in these circumstances. One posits that incumbents fear cannibalization in the marketplace and so under-invest in the new technology. The second suggests that incumbent firms develop organizational capabilities and cognitive frames that make them slow to "see" new opportunities and that make it difficult to respond effectively once the new opportunity is identified. In this paper we draw on two of the most important historical episodes in the history of the computing industry, the introduction of the PC and of the browser, to develop a third hypothesis. Both IBM and Microsoft, having been extremely successful in an old technology, came to have grave difficulties competing in the new, despite some dramatic early success. We suggest that these difficulties do not arise from cannibalization concerns or from inherited cognitive frames. Instead they reflect diseconomies of scope rooted in assets that are necessarily shared across both businesses. We show that both Microsoft and IBM were initially very successful in creating freestanding business units that could compete with entrants on their own terms, but that as the new businesses grew, the need to share key firm-level assets imposed significant costs on both businesses and created severe organizational conflict. In IBM and Microsoft's case this conflict eventually led to control over the new business being given to the old and that in both cases effectively crippled the new business.

In the fall of 2018, Hiro Mizuno, the Chief Investment Officer (CIO) of GPIF, the Japanese Government Pension Fund, was reflecting on his efforts to integrate Environmental, Social and Governance (ESG) issues into every aspect of GPIF’s portfolio. His efforts ranged from constructing new stock market indices based on ESG data, changing the compensation and incentives of active investment managers and passive funds, pushing for more corporate sustainability reporting and integrated reporting, and establishing collaborations with other asset owners to drive systems level change. He was convinced that the only way to meet his responsibilities to his beneficiaries was to improve the performance of the entire economy through a focus on improving corporate governance, increasing inclusion in the workplace and gender diversity and reducing environmental damage and progress towards tackling climate change. The early results from his efforts were promising, but was there more he could do?

Note on Economic Inequality (2018)

Rebecca Henderson, Clayton S. Rose, Jessica A. Gover and Aldo Sesia

For over half a century, most of the world's economies have enjoyed steady growth and prosperity. While this economic growth has reduced the number of people living in poverty, it has come with an increase in economic inequality. The gap between the "haves" and the "have-nots" in developed countries has widened, with a small proportion of the population reaping an increasingly larger share of a country's economic rewards. This growing economic inequality has been particularly pronounced in the United States, but the phenomenon has also occurred in many nations. This note provides background on aspects of economic inequality. It begins by describing both income inequality and wealth inequality, providing an explanation of two widely used metrics and data that show increasing inequalities over time. It then moves to the factors that might contribute to this inequality, as well to propositions of economic and social consequences that might result from the widening gap. Finally, it addresses the issue of "equality of opportunity" or social mobility. This is an update to the Note on Economic Inequality (2015). It provides additional information on economic inequality, including union membership and inequality and political polarization.

An Israeli startup founded in 2014, Zebra Medical Vision developed algorithms that produced diagnoses from X-rays, mammograms, and CT-scans. The algorithms used deep learning and digitized radiology scans to create software that could assist doctors in making diagnoses. By July 2018, Zebra had developed seven algorithms to analyze scans for emphysema, liver density, compression fractures, bone density, brain bleeds, breast cancer, and a calcium score used to detect calcified plaque in coronary arteries. For each scan analyzed, Zebra charged hospitals $1. By 2018 Zebra found itself in a race with its competitors to perfect these algorithms, create software tools, distribute the tools to physician partners, and create a market. Zebra already had several partners in the U.S. and Europe who gave feedback on its development. Management had to answer the following questions: What should they do next at Zebra? Should they work on the accuracy of the already developed algorithms or continue to develop many new tools? If they chose to develop new products, which applications should they address? And how should they go to market?
