Explore the faculty research, thought leadership, and groundbreaking philosophies that established Michigan Ross as one of the world’s top business schools.
Sensory marketing is a relatively new and growing field of marketing that Professor Aradhna Krishna pioneered in the early 2000s. Krishna saw that there were disparate fields of study on senses, but there was no cohesion between these fields. She brought all these sub-fields together under the umbrella of sensory marketing and organized the first conference on it in 2008. She then wrote two books and dozens of scholarly articles on the subject to make the field grow. And the field did grow both in academia and in practice -- enough for Harvard Business Review to do a lead Ideawatch article on it featuring Krishna as the world's foremost expert on the topic. Krishna has defined "sensory marketing" as marketing that engages the consumers' senses and affects their perception, judgment, and behavior. Krishna continues to publish important, scholarly articles on the topic. She also started the Sensory Marketing Lab at Michigan Ross, which attracts PhD students and post-docs from around the world.
In her research published in the American Economic Review, the Review of Economics and Statistics, the Journal of Human Resources, Health Affairs, and other outlets, Professor Sarah Miller has used quasi-experimental methods to evaluate whether receiving improved access to health care in utero, in early childhood, and throughout childhood improves outcomes in adulthood. Miller and her co-authors have found that children who have received eligibility for health insurance through the Medicaid program have improved outcomes on a number of dimensions, both in terms of health and economic outcomes. Additionally, they found that the children of those children who had better access to healthcare in childhood were healthier at birth. This suggests a cycle in which investing in children's health today can have multigenerational benefits that allow the government to fully recoup the cost of its initial investment in the form of higher tax payments and lower spending on welfare programs. Miller's research has been discussed in numerous high-profile news outlets and has strongly impacted how academics and policymakers view investments in children. Furthermore, her papers have been cited nearly 500 times.
Professor Gautam Kaul and two former PhD students, in their seminal 1994 study titled, "Transactions, Volume, and Volatility" convincingly argued and verified empirically that it is the occurrence of a trade in a certain direction rather than its dollar value (or volume) that has the greatest effect on prices, hence the greatest relevance when assessing the liquidity of the market where that trade took place. A trade sign is determined by the buyer or seller's information, while market conditions determine trade amount and price. This is a simple yet extremely powerful notion that was originally predicated in theory but had no empirical support before their 1994 study. The publication of this study opened the door to the accurate measurement and needed assessment of market liquidity. These days, the approach they recommended is widespread in its use.
In the book Build, Borrow, or Buy: Solving the Growth Dilemma the late Professor Will Mitchell and his co-author Laurence Capron developed a groundbreaking framework showing how firms can dynamically manage their resource portfolios and choose an appropriate growth strategy in turbulent market environments fraught with institutional, technological, and economic challenges. This comprehensive framework integrates the capability-based perspective with the principles of transaction cost economics. The intellectual origins of the capability-based perspective are deeply rooted in the foundational work in the strategy field carried out at the University of Michigan around 1980. Mitchell's foundational framework has not only shaped the research agendas of scholars interested in central questions in corporate strategy but also influenced practitioners who are faced with the perpetual strategic conundrum of how best to grow their firms.
Professor C.K. Prahalad was the major pioneer and advocate of the 'bottom of the pyramid' proposition that selling to the poor can simultaneously be profitable and help eradicate poverty. While appealing, the BOP proposition is also controversial. Professor Aneel Karnani was an early and prominent critic of the BOP proposition. In his 2007 article "The Mirage of Marketing to the Bottom of the Pyramid" and his 2011 book Fighting Poverty Together: Rethinking Strategies for Business, Governments, and Civil Society to Reduce Poverty, he argues for an alternative perspective. Rather than viewing the poor primarily as consumers, it is better to focus on the poor as producers and to emphasize buying from the poor. Both the private sector and government have a critical role to play in alleviating poverty. The best way to alleviate poverty is to raise the real income of the poor by providing them appropriate employment opportunities. The private sector is the best engine of job creation. The government should facilitate the creation and growth of private enterprises in labor-intensive sectors of the economy. The government should also fulfill its traditional, accepted functions of providing adequate access to public services, such as education, public health, drinkable water, sanitation, security, and infrastructure.
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.
With generous support from the Mitsui Life Insurance Company, Professor E. Han Kim helped to establish the Mitsui Life Financial Research Center in 1990. The center supports research in finance in a myriad of ways and functions as an active community of faculty, students, and visiting research scholars. Since its inception, the center has rapidly expanded its influence and reputation in supporting and disseminating academic research in financial economics. In 1994, a gift from Nippon Telegraph and Telephone allowed the center to offer even greater research support to Michigan Ross faculty. The center holds annual symposiums in Ann Arbor, Michigan, as well as in Tokyo, Japan, and provides research support for faculty and doctoral students through sponsoring weekly Mitsui Finance Seminars, NTT Fellowships, the Mitsui Distinguished Visiting Scholar program, weekly finance reading groups, and data acquisitions.
In the article "The Core Competence of the Corporation," Professor C. K. Prahalad and his collaborator Gary Hamel introduced a groundbreaking idea about how companies succeed.
They presented the idea that rather than just looking at the products they sell, companies should identify and nurture their core competencies -- the unique abilities and strengths that make them stand out. Those competencies are born from collective experience and knowledge in the company and combine different skills and technologies. Additionally, core competencies are not easy for competitors to copy, therefore giving companies a lasting edge in the market.
In their article, Prahalad and Hamel cautioned companies not to get overly wrapped up in their current products, which might change with time. They advised that instead, companies should focus on understanding and enhancing their deep-rooted strengths as they pave the way for future innovations and market leadership. By recognizing and harnessing core competencies, companies can venture into new markets, innovate, and stay ahead of the competition. In simple terms, companies should know and recognize what they are genuinely good at and use that to shape their future.
From 2000 to 2005, Professors C.K. Prahalad and M.S. Krishnan co-authored several papers on concepts related to how the emergence of digital technologies was transforming business models. From 2005 to 2008, they co-authored the book New Age of Innovation, which introduced the concept of N=1;R=G business model framework. The basic argument was that given the new capabilities emerging from digital technologies, the structure of business models was in the midst of a transformation across industries. They claimed that business models will shift from mass production of products or services to businesses co-creating personalized experiences for one customer at a time. They called this N=1 business model, i.e., businesses will operate on a sample size (N) of one. They argued that to orchestrate this personalized experience for one customer at a time, businesses will not own all resources but will connect with resource partners across the globe (Resources=Global or R=G), and these partners could be big organizations, small businesses, entrepreneurs, or even individuals. They called this business model N=1;R=G. They argued that digital technology was at the center of enabling these capabilities, and no industry will be immune to this change. They presented more than 80 examples in the book. The rest of the book was on the capabilities companies needed to build inside their organizations to compete as an N=1 business. Their primary thesis identified the significant role of software in orchestrating the personalized N=1 experience in an ecosystem of partners and the criticality of the right capabilities in the information architecture and social architecture of companies to thrive in this competition of N=1;R=G ecosystem business models.
Professor Jim Walsh was elected as the 65th president of the Academy of Management in 2006, making him only the second Michigan faculty member to lead the Academy. Walsh took stock of the approximately 16,000 members who lived in more than 100 countries at the time and noted that very few of them resided on the continent of Africa. Knowing that Africa, the cradle of civilization, is home to over a billion people and more than 1,000 universities and that the continent was poised for enormous population and economic growth, he wanted to bridge the gap and reach out to the teacher-scholars on the continent. Fully aware of the terrible history of colonization, he decided to simply create space for colleagues in Africa to meet their colleagues from the rest of the world. The first step in the process was to work with others to co-found the African Academy of Management. His continued work culminated in a 2013 AOM Africa Conference, in which approximately 300 colleagues from the world over journeyed to Johannesburg to share and imagine new research and teaching ideas. Since that time, the Africa Academy of Management has hosted a number of faculty development workshops, launched the Africa Journal of Management, and held conferences across the continent. In short, Africa-centered scholarship has burgeoned. Beyond that, the Ross School was just granted affiliate member status in the Association of African Business Schools. Professor Walsh wanted to be sure that we too are a part of the emerging scholarly conversations and evolving business practices on the continent.
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.
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.
Professors Norman Bishara and Jagadeesh Sivadasan have made significant contributions to influential literature examining the variation in the enforceability of non-compete clauses and their consequences. Their work is an important part of broader literature documenting monopsony power (i.e., the power of employees to set wages leading to a redistribution of surpluses away from workers), worker mobility, and knowledge transfers. In a pioneering paper published in 2010, Bishara created a detailed rating of the non-compete enforceability in all 50 states, building on painstaking work parsing the regulations and case law at the state level. The enforceability index from Bishara's 2010 paper, combined with worker-quarter-level U.S. Census data, was used in a paper by Sivadasan and co-authors to show that higher enforceability is correlated with lower wages and mobility for tech workers.
Bishara and his U-M coauthors also undertook a broad survey of U.S. workers, documenting for the first time the surprising prevalence of the use of non-compete clauses across a range of industries, including for low-wage workers, as well as work showing the chilling effect of noncompetes on employee behavior, even when they are unenforceable. This portfolio of work helped spark a major policy debate about the use and abuse of noncompetes that inspired action from the White House and the research conclusions being cited in the 2023 State of the Union Address, and spurred a report from U.S. Treasury Department, legislative changes from numerous states, and research from a range of think tanks that eventually led to the 2024 final rule from the Federal Trade Commission attempting to ban noncompetes in employment contracts across the country.
Professor David Brophy brought the study of small businesses and private financial markets (now known as alternative, in contrast to publicly traded markets) to Michigan Ross and the state of Michigan before it was recognized as a legitimate area of study at top research universities. This process started in the mid-to-late seventies, and Brophy relentlessly created awareness in Michigan and educated students interested in this space. For over fifty decades, until his recent retirement, Brophy designed and taught all Michigan Ross venture capital and private equity courses.
The original trading floor at the Michigan Business School was established in 1999. At the time, it was the 12th academic trading lab to be developed in the United States and one of the first in a large public university.
Later, with a generous donation by John and Georgene Tozzi, a new lab was built. Over the years, thousands of students have come through the lab.
Today, there are approximately a dozen investment clubs, seven of which meet weekly in the lab. When the lab was first getting started, the student-managed fund was at $95,000, which has since grown to $700,000.
Professor Joel Slemrod has worked on an agenda to broaden the scope of tax analysis to address several issues that standard economics models of taxation ignore. He has written several articles analyzing and addressing the blind spots of standard economics models and has co-authored a book titled Tax Systems, which outlines the implications of these blind spots. The influence of his work is demonstrated by the recent policy attention given to tax enforcement in the United States and other countries, such as an increase in funding appropriated to the IRS to reduce evasion of high-income individuals and corporations, as well as innovative administrative policy developments through the U.S. Foreign Account Tax Compliance Act and the OECD Pillars One and Two, which subjects a group of large multinational companies to a global minimum corporate tax of 15%. Slemrod's work has received over 35,000 citations, numerous awards and accolades, and a No. 1 ranking among public finance economists per the Research Papers In Economics site.
