Explore the faculty research, thought leadership, and groundbreaking philosophies that established Michigan Ross as one of the world’s top business schools.
The public corporation in America is vanishing, and more people, from low-income earners to professionals, are doing their work in the so-called “gig economy.” The work of Professors Jerry Davis and Sue Ashford put these two issues on the research agenda of scholarly colleagues. Davis documents the first idea in his book, The Vanishing American Corporation (2016). Although some scholars have suggested that over-regulation might account for this surprising trend, he argues that a more fundamental shift in the economy, enabled by information and communication technologies, was ultimately responsible. By making it cheaper to "buy" rather than "make" inputs (from capital and labor to supplies, manufacturing, and distribution), information and communication technologies have made the parts of an enterprise like a pile of Legos, ready to assemble into a business, scale, and disassemble. This idea explains Nikefication, Uberization, Amazon, and other recent trends in the organization of the U.S. economy, as well as why the same technologies are used differently in different countries, resulting in very different corporate structures. If what Davis says is true, then fewer people will be working in large public corporation settings going forward. This shift may account for the growth in people working independently, some using technologically mediated apps to find and conduct work. Ashford puts the gig economy and gig workers on the agenda of people wanting to understand individuals at work. Her qualitative and quantitative studies identify the challenges faced by those working independently and what they can do to survive and thrive. Challenges include maintaining one’s identity, keeping sufficient income flowing in, staying organized, finding and maintaining work connections, and figuring out how to make working in this manner work over the long run. This research tests a variety of interventions and solicits ideas from individuals working in this manner regarding strategies that make this kind of work-life viable and enlivening.
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.
Under the leadership of Marian Krzyzowski, Michigan Ross launched the Domestic Corps in 1992 with financial support from the United States Department of Education Fund for the Improvement of Post-Secondary Education. The Domestic Corps provided leadership development and action-based learning opportunities for Ross students while providing critical business assistance to the non-profit community in the United States. For 15 years, the Domestic Corps placed hundreds of students in more than 100 non-profit organizations nationwide, where they worked on projects in economically distressed and culturally diverse communities. That included Native American communities, inner city community-based organizations, and rural non-profits. The Domestic Corps also partnered with the University of Michigan's Neighborhood AmeriCorps Program to place MBA interns in 20 more than Detroit community-based organizations. The Domestic Corps projects helped raise millions of dollars, won national awards for community and economic development, and transformed numerous organizations while simultaneously providing students with management experience in challenging contexts and instilling a sense of corporate responsibility and social justice.
Professor Gretchen Spreitzer received her PhD from Michigan Ross in 1992. Her work on empowerment, stemming from her Michigan Ross dissertation, has set the foundation for a new understanding of the employee experience. Instead of capital that organizations needed to control, empowerment brought forth the idea that employees thrive when they are given the freedom and autonomy to do their work autonomously. This pioneering work ushered in a new era of research and a fundamental shift in how organizations view their relationship with employees.
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 George Siedel was a pioneer in developing the concept of law as a source of competitive advantage. This concept originated in his 2002 book: Using the Law for Competitive Advantage. In an article in the Academy of Management Executive, Robert Thomas (past president of the Academy of Legal Studies in Business), concluded that the book "is trailblazing in its assertion that legal issues are critical strategic variables in business planning." Siedel later emphasized an international dimension to his work in his 2010 book: Proactive Law for Managers: A Hidden Source of Competitive Advantage. This work has served as a foundation for academic and practitioner interest in the design and simplification of contracts and other legal documents.
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.
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.
The marketing faculty at the University of Michigan has, over the decades, made several foundational contributions to the area of consumer behavior. Professor Joseph W. Newman, who was a marketing faculty member at the Michigan Business School from 1949-51 and again from 1965-73, helped greatly through his books and research publications to deepen the impact on the marketing discipline of concepts including economics and decision theory, psychology, sociology, and anthropology, especially through the qualitative research techniques of motivational research. Along with his doctoral students, he published highly impactful research on how consumers gather and use pre-purchase information. He also published research on customer satisfaction and dissatisfaction. For these and other contributions, he was named a fellow of the Association of Consumer Research in 1990, its highest honor. In the decades since, the marketing faculty at Michigan Ross has continued to make many more notable contributions to our understanding of consumer behavior.
If people don’t pay much attention to the ads when they watch TV, they can’t possibly think a lot about what the ads are saying. How, then, does advertising have the effects on consumer buying that it does? Showing that emotional responses evoked by the ad play an important role was a major research contribution by Rajeev Batra, Michigan Ross marketing professor. Batra came to U-M in 1989 from Columbia University, where he began this research stream. Over 10 years at MichiganRoss, he grew this research stream to show more clearly how these ad-evoked emotions interacted with the ads’ more rational content, what the different types of ad-evoked emotions were and how they could be measured accurately, and how they shaped consumers’ liking for and perceptions about brands. His co-authored papers on these topics have been cited more than 8,000 times, and he has twice been listed among the most influential scholars in the study of advertising. The methods he developed for measuring the types and effectiveness of emotional ads have also been incorporated into copy-testing systems at multiple ad agencies.
In 2008, an article by Michigan Ross Professor Scott Rick changed how academics, practitioners, and the general public thought about consumers’ spending habits. The key insight was that many people who spend very little are frustrated with their behavior. They consistently spend less than they think they should, often with negative consequences for themselves and those around them. Under-spenders (“tightwads”) and over-spenders (“spendthrifts”) are two sides of the same coin: both experience conflict and distress around their spending habits. The scale Rick and colleagues developed to measure these tendencies has become widely used by marketing and psychology researchers. The tightwad-spendthrift construct attracted even more attention when Rick and colleagues demonstrated that tightwads and spendthrifts are more likely to marry one another than they are to marry someone like themselves. This “opposites attract” pattern is initially enjoyable, but eventually, as partners begin to confront a never-ending series of joint spending and saving decisions, tightwad-spendthrift differences harm relationship quality.
This research has attracted broad attention beyond the boundaries of marketing academia. It has been the topic of webinars, podcasts, and other features produced by the National Science Foundation, the American Psychological Association, the National Academy of Sciences, and the World Economic Forum. It has received years of sustained coverage from media outlets such as NPR, the New York Times, and the Wall Street Journal. Financial organizations like the CFP Board, ING, Charles Schwab, and Equifax have informed their clients and customers about the implications of this research. Most notably, in 2024, St. Martin’s Press published a mass-market book about this research, titled Tightwads and Spendthrifts: Navigating the Money Minefield in Real Relationships.
Associate Professor Anant Nyshadham co-founded and co-directs the Good Business Lab, a labor research and innovation lab whose work to identify workplace tools and interventions to deliver both impact to workers and returns to employers has quickly expanded across four continents over the last decade. Designed and tested through rigorous randomized controlled trials in real-world workplaces, GBL has developed several tools for rapid and broad scale. GBL's worker voice tool, Inache, has been proven to improve worker retention, reduce absenteeism, and increase worker productivity in manufacturing settings. Similarly, the tool Pratibha is a tablet-based screening and training tool for frontline supervisors that measures and addresses soft skill deficiencies and has been proven to improve the retention of supervisors and dramatically and sustainably raise the productivity of workers in factories. The Bill and Melinda Gates Foundation recently awarded GBL a multi-million dollar grant to scale these tools to more than a million workers in the next two years.
The paper "Quantity Flexibility Contracts and Supply Chain Performance" by Professor Bill Lovejoy and his colleague, Andy Tsay from Santa Clara University, was published in Manufacturing & Service Operations Management in 1999. The paper delves into the concept of quantity flexibility in supply chain contracts and its potential to deal with demand uncertainties. This influential work formally captured the practice of “funneling” variability over time, whereby more variability is tolerated in earlier planning phases and less tolerated over time as the delivery date approaches. This paper has specifically led to further studies on the optimal design and effectiveness of supply chain contracts, enhancing the field’s understanding of tactical and strategic issues in supply chain management. Researchers have built on Tsay and Lovejoy's model to study the application of QF contracts in different industrial contexts and their interactions with various supply chain configurations. The concept and modeling presented in this paper have become a prominent part of the academic discourse on supply chain coordination, influencing subsequent studies in inventory management, order variability, and supply chain profitability. Thus, the paper's impact is significant and broad, inspiring much-needed research on flexible, cooperative strategies for supply chain optimization.
Every innovation or new product development team faces a fundamental tension: When does one transition from the ideation to the execution phase? Too early a transition risks missing a great yet unrealized idea, and too late a transition risks being unable to bring the product to market on time. This significant and ubiquitous tension poses a challenge for researchers because of the nuanced nature of imagination and creativity and the need to combine that with creating an actual item based on one’s designs. In “Ideation-Execution Transition in Product Development: An Experimental Analysis” (Management Science, 2018) by Michigan Ross Professors Stephen Leider and William Lovejoy, as well as their colleague Evgeny Kagan from the Johns Hopkins Carey Business School, the authors use a novel experimental design to reveal some expected outcomes (later transitions do not change mean performance but increase variance and risk significantly) and some unexpected ones (it is not so much the timing of the transition that drives mean performance, but rather who has decision rights). Specifically, designers should not make the transition decision; the timing should be an exogenously imposed constraint. This external requirement significantly changes designers’ behaviors and results.
The Dare to Dream grant program is an initiative by the Zell Lurie Institute for Entrepreneurial Studies. It provides funding to U-M students interested in exploring and pursuing entrepreneurial ventures.
The student grant program offers three different tracks targeted toward early-stage students looking to develop a business concept to integrate entrepreneurship into their academic studies, students who have already developed a business concept and are seeking to validate and assess the feasibility of their idea, and students who are ready to launch their ventures.
In 1993, former Michigan Ross finance faculty member Victor Ng, co-authored a paper that is among the top 50 most cited papers in finance. Ng's paper defines the news impact curve, which measures how new information is incorporated into volatility estimates. His paper compares and estimates various new and existing autoregressive conditional heteroskedasticity models, including a partially nonparametric one, with daily Japanese stock return data. New diagnostic tests are presented which emphasize the asymmetry of the volatility response to news. Ng's results suggest that the Glosten, Jagannathan, and Runkle Model is the best parametric model. This path-breaking paper demonstrates the use of a new methodology to show the impact of news on stock prices, probably the most important function of financial markets.
