Explore the faculty research, thought leadership, and groundbreaking philosophies that established Michigan Ross as one of the world’s top business schools.
The paper "CONWIP: a pull alternative to kanban" by Professor Wally Hopp and coauthors, published in The International Journal of Production Research in 1990, presents an innovative production control method known as Constant Work-In-Process. CONWIP represents a notable advance over the well-known Kanban approach of the Toyota Production System that outperforms Kanban under a wide range of settings, is more adaptable to variability, and, unlike Kanban, is suited to environments with a large number of products. The path-breaking analysis of this paper spurred a significant stream of research into the performance of pull production systems that continues to this day. CONWIP has also become a standard part of the operations lexicon and has seen widespread application in industrial settings. Finally, CONWIP was an essential building block of the science of manufacturing that Wally and others introduced as Factory Physics in subsequent work.
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.
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.
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 root of the Great Financial Crisis of 2008-2009 lay in poor-quality residential mortgage loans made by financial institutions. A set of academic research papers established that lenders made poorer quality loans when they anticipated selling the loans to investors rather than continuing to own the loans until they matured. When loans were sold, a complex securitization process led to a large distance between the originator of a mortgage and the final investor in the loans. Amit Seru, PhD '07, and co-authors established in an important series of papers that focused on 1) keeping most characteristics of loans the same, loans that were only marginally easier to securitize had significantly higher default rates than those that were marginally more difficult to securitize, 2) (in work with Professor Uday Rajan) securitized loans, the interest rate (which represents the compensation to investors for bearing the risk of default by the borrower) became an increasingly worse predictor of default in the build-up to the GFC, and 3) information passed on to investors by mortgage securitizers was limited and sometimes outright fraudulent. In another crucial strand of work, Professor Amiyatosh Purnanandam demonstrated that 1) loans held by banks on their own balance sheets had lower default rates than otherwise identical loans sold by banks to investors and 2) (in work with Taylor Begley, PhD '14, and Kuncheng Zheng, PhD '15) even with securitized loans, default rates were lower when the riskiest tranche was held by the lender rather than sold to investors. Collectively, the work done by Ross faculty and PhD alums showed that the ability to securitize mortgage loans undermined the incentives of lenders to the point that low-quality mortgage loans were made, essentially providing the dry timber that fueled the GFC.
Building on his experience as an attorney at the Federal Reserve, the 2020-22 research of Assistant Professor Jeremy Kress has identified critical weaknesses in bank merger oversight and proposed strategies to reinvigorate bank merger enforcement. Kress' work has shown that lax bank merger oversight has harmed consumers, businesses, and the broader financial system. His research has demonstrated that the prevailing approach to bank merger regulation has increased the cost and reduced the availability of consumer credit, inflated the fees that banks charge for basic financial services, limited small business credit availability, and threatened financial stability. Kress' research has pushed bank merger reform onto the policy agenda in Washington, D.C. by serving as a blueprint for legislation introduced by Senator Elizabeth Warren and inspiring an executive order on bank mergers by President Joe Biden. The Department of Justice also invited Kress to lead a joint initiative with the federal banking agencies to rewrite their bank merger policies.
Beginning from seminal efforts by Brian Talbot at the Michigan Business School in the early 1990s, the Tauber Institute for Global Operations was designed to bring business and engineering students together for a world-class education in operations. Students would take classes in both business and engineering and complete team projects with companies. The projects were scoped to incorporate both business and engineering content, addressing important problems that had a VP-level champion at the sponsoring company. The institute was innovative by offering additional training to students beyond operations: leadership training, communications training, and providing students the opportunity to organize conferences, etc. In addition to its impact on students and companies, the Institute has for years served as an important mechanism fueling the technology and operations faculty's relevant, problem-driven research by putting them in touch with practitioners at leading companies around the world. Since its foundation, more than 1,500 graduates have completed the program as Tauber Fellows, there have been 720 summer projects executed at 145 companies, and the Institute was honored in 2012 with the prestigious UPS George D. Smith Prize from INFORMS.
The Integrated Product Development course is a unique cross-disciplinary experiential course delivered jointly by Michigan Ross, the College of Engineering, and the Stamps School of Art and Design. The course requires teams of business, engineering, and art students to execute the full range of the product development and launch process, from early-stage ideation through design and fabrication to launch stage promotion, pricing, and inventory decisions.
It has been continuously offered for more than 30 years and has been featured on CNN and in BusinessWeek, the New York Times, and the Wall Street Journal. Professor William Lovejoy originally designed this course, but it was subsequently taught by a series of dedicated professors drawn from the three units. It remains a course students remember and refer back to throughout their professional careers.
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.
Former Michigan Ross Professor Gautam Ahuja's "Collaboration Networks, Structural Holes, and Innovation: A Longitudinal Study" marked a significant turn in the way scholars view the impact of inter-organizational networks on innovation. Until this point, the common perception was more or less linear: the more connections a firm has, the better it is for innovation. However, Ahuja's research added a layer of complexity by considering indirect ties and structural holes in a firm's network. The results of Ahuja's study challenged existing theories at the time and opened up an entirely new area of research. Now, scholars must consider not only the quantity of a firm's connections but also their quality and structure and how these elements influence innovation. This nuanced understanding helped expand the study of inter-organizational networks, underlining how the firms' positions within such networks can dictate their innovation output. This paper is credited with kickstarting a whole new area of research -- inter-organizational networks and innovation -- which focuses not just on the number of connections a firm has but the whole structure of its network and how it impacts its ability to innovate.
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.
Currently organized by the Sanger Leadership Center, the Leadership Crisis Challenge partly came about based on Sue Ashford’s vision as the then head of the Ross Leadership Initiative and the enthusiasm of students wanting to create more venues to discuss complex and problematic business issues, such as the role of business in addressing society's most difficult problems and how businesses and other leaders might think about tensions between financial and environmental goals. Additionally, there was an interest in understanding how students, as future leaders, might best think about issues of corporate social responsibility. The LCC was intended to address those student interests by putting students in groups of four and asking them to exercise their courage, judgment, and integrity in response to a complex crisis situation and under strict time pressure. In the crisis challenge, students are confronted with a complex case for which there is no right answer or winning position – there are just tradeoffs. Built into the case are some of the most vexing questions of the day, including: What does a company “owe” the community in which it does business? Should the natural environment be sacrificed for shareholder wealth? Can companies admit wrongs in today’s aggressive legal climate? With the input of previous participants, the Net Impact club, and members of the faculty, a new case is prepared every year and overseen and judged by Michigan Ross community members, business leaders, and alums.
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.

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.
