Explore the faculty research, thought leadership, and groundbreaking philosophies that established Michigan Ross as one of the world’s top business schools.
In 1985, Professor M.P. Narayanan published a paper on managers' proclivity to focus on the short- rather than the long-term. His paper is a rigorous and theoretical explanation that requires the manager to have private information. Narayanan shows that the manager's proclivity to focus on the short-term is more evident in a less experienced manager but is attenuated if the business's riskiness and the contract's length increase. While singling out the importance of the short- and long-term conflict as the basis for the myopic behavior of firms may be a challenge, this phenomenon is ever-present.
The Affordable Care Act represented arguably the largest change in federal health policy since the creation of the Medicare and Medicaid programs in the 1960s, expanding coverage to approximately 40 million people who were previously uninsured. In a series of papers published in the Quarterly Journal of Economics, New England Journal of Medicine, AEJ: Applied Economics, Journal of Public Economics, and other outlets, Associate Professor Sarah Miller and her co-author Dr. Lara R. Wherry quantify the impact of this policy on the predominantly low-income population who gained coverage as a result of the reform's resultant changes in Medicaid eligibility. Their work has shown that 1) low-income adults who gained coverage through the ACA Medicaid expansions experienced reduced mortality rates and that the failure of some states to adopt these expansions cost approximately 4,800 deaths per year in those states; 2) low-income adults who gained coverage through these expansions experienced improved access to medical care and improved financial outcomes; 3) the expansion of coverage to these individuals did not crowd out care provided to population who were unaffected, such as those in Medicare. This work has garnered over 1,800 citations and has been discussed in numerous high-profile media outlets and policy documents.
Michigan Ross is known for being one of the first places to promote and provide rigorous evidence contrary to the efficient market hypothesis. The work of Professor Victor Bernard, a faculty member from 1982-1995, played a huge role in the beginnings of literature on market inefficiency. His work in valuation and fundamental analysis was the first to provide evidence that investors could not fully process information in earnings releases. The inefficient markets argument was further supported by the work of Professor Richard Sloan, a faculty member from 1997-2007. Bernard demonstrated that market participants treat the two basic components of accounting — cash and accruals — in an irrational way when making their valuation of corporate securities. This behavior became known as the "accrual anomaly." Bernard's work twice won the Notable Contribution to the Accounting Literature Award.
Michigan Business School Professor and Erb Institute Faculty Director,Tom Gladwin, pioneered the field of business sustainability with his concept of a "science of sustainable enterprise." It was one of the first scholarly frameworks to bring together the social, environmental, economic, and organizational aspects of competitive companies that likewise are managed to explicitly create value for society. With groundbreaking publications like "Shifting Paradigms for Sustainable Development: Implications for Management Theory and Research" and "Beyond Eco-Efficiency: Towards Socially Sustainable Business" in the 1990s, Gladwin dramatically expanded the scope of traditional management education and business leadership. Throughout his career, and his long-time partnership with the Prince of Wales's Business & the Environment Programme, Gladwin influenced hundreds of CEOs and other top corporate leaders to think deeply about, and take action on, the threat and the opportunity of sustainable business.
In 2006, Professor Sue Ashford, associate dean for leadership programming, founded the Ross Leadership Initiative, which was the precursor to the Sanger Leadership Center and one of the first organized leadership programs among business schools worldwide. The initiative was influenced by Ashford's research on learning leadership via experience and Professor Noel Tichy's action-based learning concepts. Suddenly students were not just learning about leadership but were actually engaged in doing it. Prominent among these efforts was the highly influential Leadership Crisis Challenge, which puts students in the hot seat needing to resolve a crisis in the moment. This program was recognized with the Provost's Teaching Innovation Prize in 2011 and remains a prominent and popular program in the school to this day. Later, under the leadership of Professors Scott DeRue and Gretchen Spreitzer, RLI grew and launched new programs that persist today, including Story Lab, the Ross Leaders Academy, and more. In 2015, alum Stephen W. Sanger, MBA '70, and Karen Sanger made a defining gift of $20 million to establish the Sanger Leadership Center. With the Sangers' gift, the Sanger Leadership Center, now under the leadership of Professor Lindy Greer, has created an array of custom programs and workshops and now offers leadership development programs for students across the university.
Professor David Hess is a thought leader in using new governance regulatory theory to advance the effective and efficient use of corporate monitors in U.S. and international settings. Hess and his co-authors published their first research on the topic in 2008 in the Cornell International Law Journal.
Since then, David has become a recognized thought leader with multiple published articles and book chapters on using monitors in settlement agreements to battle corruption and cultivate ethical behavior.
Based on his expertise, in 2013, the American Bar Association's Task Force on Standards for Monitors asked Hess to serve as its reporter. In 2020, the ABA published the 77-page Criminal Justice Monitors and Monitoring Standards. Hess' role as a reporter required that he draft and revise the standards before each meeting to reflect task force input.
This required legal research and drafting of explanatory memoranda as well as responding to comments and concerns of task force members and ABA officials. The Standards are used by companies, prosecutors, and judges when considering the use of corporate monitors with Deferred Prosecution Agreements or other settlement agreements resulting from concerns about fraud or other misconduct. The Standards may be used by other countries when establishing monitoring programs.
Professor Emerita Valerie Suslow and Adjunct Professor Margaret Levenstein have pursued a collaborative research agenda on the economics of cooperative behavior among firms, with a specific focus on cartels. Agreements between competing firms to reduce the intensity of competition can include actions such as price fixing, allocating geographic markets, allocating customers, and bid-rigging at auctions. Historically, such cooperative behavior was legal throughout the world but illegal in the United States under the Sherman Act of 1890.
The U.S. National Industrial Recovery Act of the early 1930s suspended price-fixing antitrust laws in certain circumstances. In the mid-1990s, after many decades of inattention, it became clear to competition policy enforcers that cartel activity was rampant and was likely causing substantial consumer harm. This spurred new leniency and amnesty policy tools to become available to firms. In their highly cited article "What Determines Cartel Success?" Levenstein and Suslow make the case that while cartels may break up due to cheating on the agreement, the more insurmountable problems are entry and adjustments in the face of changing economic conditions. "Breaking Up Is Hard to Do: Determinants of Cartel Duration" shows that cartels that turn to price wars to punish cheaters are not stable. Highly stable cartels draw upon a vast toolkit of mechanisms to enhance their stability and, therefore, their duration and economic harm.
Levenstein and Suslow's work has been cited in policy reports by organizations around the world, such as the Organization for Economic Cooperation and Development, the United Nations, and the World Trade Organization. They continue to explore hidden or overlooked sources of harm to consumers that may result from cartel activity, most recently turning their attention to the role played by vertical relationships between firms engaged in horizontal collusion, as well as how collusion may be facilitated by the use of a price index in long-term contracts.
Franchised chains have an outsize influence on the economy: firms involved in a variety of business activities are organized as franchised chains and they employed over 9.6 million workers in the United States in 2017 according to the Census Bureau. Professor Francine Lafontaine's pioneering work on franchising shows that the success of this organizational form across various sectors results from the franchisor and franchisee specializing in the activities they are best suited to. Specifically, the franchisor specializes in creating and supporting the business format and brand, where scale is especially beneficial, and the franchisee optimizes operations locally, where their knowledge and efforts are particularly valuable. Lafontaine's work in this area has informed the choices that franchisors make and the nature of the contracts they use, and also the debate over legislation that aims to address the alleged shortcomings of the franchising organizational form.
Her work suggests caution in developing potential public policy changes as consumers, existing and potential franchisees, as well as their employees stand to lose in the long term if franchising becomes less competitive as a form of organization. More broadly, Lafontaine's research has made seminal contributions to our understanding of how firms interact with each other in the process of procuring inputs or distributing their products, and prompted her appointment as Director of the Bureau of Economics at the FTC in 2014-15. In particular, her research has shown that factors driving vertical integration and vertical contracting can be very different from those motivating horizontal mergers, so analyses of vertical mergers should start from a different premise compared to analyses of horizontal mergers. Her detailed analyses of franchise contract terms, as described in her book The Economics of Franchising, provide further reasons why, in her view, the rule of reason continues to be the right approach in antitrust cases involving vertical restraints.
Changes in health care structure following World War II brought the need for increased legislation, regulations, and court oversight to the industry. Professor Arthur Southwick of the Michigan Business School was a leader in developing these diverse sources into a coherent framework that enabled academics, healthcare leaders, and students to understand this emerging area of law.
According to Wharton Professor Arnold Rosoff, Southwick's book, The Law of Hospital and Health Care Administration, first published in 1978, "was a central fixture in the field's literature and the means by which countless numbers of hospital administrators learned about the laws that so significantly defined their field of practice." In this way, Southwick was a thought leader in developing healthcare law. In addition to his intellectual leadership in the healthcare field, Southwick served on the State Health Planning Advisory Council in Michigan and played a key role in founding what has become the 12,500-member American Health Law Association.
Michigan Ross has long been a pioneer in entrepreneurial education, introducing the nation's first course on entrepreneurship in 1927. However, in the early 1970s, Professor LaRue Hosmer played a pivotal role in championing entrepreneurship education at Ross. He developed and taught courses in small business management and a seminar on small business formation. He is considered the founder of the Michigan Entrepreneur Track and has also inspired present-day entrepreneurship faculty at Michigan Ross, including Professor Andy Lawlor. Lawlor was a student in Hosmer's entrepreneurial management course in 1973, and Hosmer has been an important mentor to Lawlor, helping to bridge the gap between business and teaching. Lawlor began guest lecturing under Hosmer's guidance in 1975 and assumed the teaching responsibilities for the entrepreneurship classes in 1981. Over the years, many successful companies have been born from Hosmer and Lawlor's teaching.
In 2002, Professor C.K. Prahalad of the Michigan Ross Business School and professor Stuart L. Hart of the University of North Carolina Kenan-Flagler Business School published the iconic article "The Fortune at the Bottom of the Pyramid" in Strategy+Business. The article suggested that "low-income markets present a prodigious opportunity for the world's wealthiest companies - to seek their fortunes and bring prosperity to the aspiring poor." Prahalad published a book with the same title five years before he passed in 2010. The article and book, with additional research and publications by Prahalad, Hart, Michigan Ross Professor Ted London, and others spawned a new business strategy for human development that has transformed into a social movement around the world known as Base of the Pyramid. The movement now includes transnationals, non-profits, social entrepreneurs, grassroots development organizations, international aid agencies, and many consulting firms dedicated to BoP strategy and implementation.
In a paper published as a lead article in the Journal of Finance in 1990, Professor Nejat Seyhun investigated whether informed investors stabilize and correct mistakes in security prices by buying undervalued assets and selling overvalued assets or destabilize security prices by jumping into already overpriced securities to create bigger bubbles and mis-valuations first, only to exploit them later. Seyhun's investigation centered on the stock market crash of Oct. 19, 1987, when the stock market crashed by 22% in one day. He found that top corporate insiders bought undervalued stocks and sold overvalued stocks in record quantities immediately following the crash. Hence, informed insiders were stabilizing security prices and not destabilizing them further. This finding provides comfort that the stock market will be self-policing and self-correcting and justifies the current regulatory system, which assumes that more information is beneficial by requiring timely, accurate, and full dissemination of information from all parties involved. Seyhun was among the first to explore various aspects of reported insider trading and its effects on share prices and shareholder wealth.
Professor Kenneth Lieberthal was a pioneer in the practice of business school professors contributing their knowledge in public service to society. Lieberthal served as the senior director for Asia for the U.S. National Security Council during the years 1998-2000.
During that same time, Lieberthal was also special assistant to President Clinton for National Security Affairs. His core academic research findings included a seminal analysis of China's bureaucratic system, which featured a nuanced and careful delineation of the fragmented nature of China's political system in the late 20th century.
Lieberthal's research was able to explain why China, during that era, had weak policy implementation at times because of the fragmentation in its bureaucratic system. He was known for introducing U.S. policymakers to a nuanced and careful understanding of the Chinese governmental system and how it functions.
William Davidson (1922-2009) was a successful global business leader and alum of the University of Michigan. He understood the value of the private sector to empower people around the world.
After the fall of the Berlin Wall, Davidson recognized the value of educating and empowering economic decision-makers in formerly centralized economies with the tools of commercial success. Davidson partnered with U-M to create a unique institute providing consulting and training services to nonprofits, corporations and small businesses in emerging markets with the goals of economic growth and social progress. Since 1992, the William Davidson Institute (WDI) has served as a platform to introduce students to the challenges and opportunities facing firms in low- and middle-income countries.
Over its history, the Institute has supported U-M student teams, totaling more than 1,800 students, who collaborate with business and nonprofit partners to provide analysis and develop solutions built upon the foundation of basic business principles. To ensure ongoing access to current and relevant business education, WDI Publishing also produces and distributes high-quality, cutting-edge business cases and other teaching materials, with more than 700 cases in its collection, reaching approximately 800 universities and institutions globally.
The Institute is also home to NextBillion.net, an online platform for discussing business models and innovations that address development challenges in low- and middle-income countries. The platform reaches more than 25,000 readers a month.
Previously, it was commonly believed that the media had little role to play in capital markets -- that they neither produced information nor disseminated information in a meaningful manner. Professor Greg Miller questioned this logic and set out to see if there was empirical evidence that would support such an assumption.
Miller found that the business press acted as a corporate watchdog that was instrumental in uncovering financial misconduct. As such, the business press was no longer viewed as talking heads, but as investigative journalism which brought value to the market through the governance role it played. With the more recent introduction of social media, many believed that social media had no role to play in capital markets. A team of researchers from U-M, including Beth Blankespor, Miller, and Hal White, decided to take a novel approach and see if social media could improve capital market outcomes.
Their work was the first to show that social media played an important role in disseminating corporate financial information. Their foundation of research was instrumental in corporate investor relation groups adopting social media to disseminate information to market participants.
In the early 2000s, Professors Tim Fort and Cindy Schipani held the first conference on the role of business in promoting peace. The conference was attended by former Secretary of State Madeline Albright and brought together individuals from academia, business, and government to discuss efforts that could be made to reduce violence in the world. It was concluded that there is a role of business, especially in serving as an unofficial ambassador or role model when conducting business internationally. This event set in motion the beginnings of a new research paradigm on "Peace Through Commerce."
