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.

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 Dudley Maynard Phelps, who was part of the Michigan Business School faculty from 1924-67, studied and wrote about the distinct marketing environments and challenges in markets as diverse as Latin America, Western Europe, and the former Soviet Union, including work for the U.S. State Department. He received recognition for this work from the International Marketing Institute and was president of the American Marketing Association. In the 1980s, Professor Vern Terpstra continued this work and authored the most widely used text on international marketing and other books on the cultural environment of international business, and also published highly impactful research on country-of-origin effects with his PhD student C. Min Han. Terpstra was president of the Academy of International Business in 1970 and was invited to teach at several universities.

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.

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.

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.

In their paper, “Crowdfunding the Front Lines: An Empirical Study of Teacher-Driven School Improvement,” Professors Samantha Keppler, Jun Li, and Andrew Wu conducted the first large-scale empirical test of the frontline improvement theory in K-12 schools. The theory, originating in automotive manufacturing, states that empowering front-line employees to identify organizational and process problems and implement solutions improves organizational performance and customer satisfaction. In this case, the team of Michigan Ross professors was interested in how teacher-identified problems in the classroom and crowd-funded solutions improved learning outcomes for K-12 students.

The team analyzed data on thousands of K-12 teacher projects on the largest teacher crowdfunding site, DonorsChoose. They found that one funded project (about $400 in value), on average, achieves a significant increase in the percentage of students scoring basic and above on all tested subjects in high school, as well as science and language arts in primary and middle schools. This effect translates to two-nine additional students moving up to at least a basic level of proficiency in the correlating subject. The effect of these projects is greatest in low-income schools, where funded projects, on average, move four-10 additional students to at least a basic level of proficiency in tested subjects.

From the textual analyses of the teacher's written statements about the impact of the projects in their schools, Keppler, Li, and Wu additionally learned that student academic performance is significantly better when teachers use crowd-funded money to improve knowledge retention, as a repeated learning tool, and to differentiate or personalize learning.

Due to the demonstrated impact of teacher-driven crowdfunded projects, DonorsChoose has partnered with eight states to spend COVID-19 education relief funding on teacher crowdfunding projects. To date, these partnerships have funded over $100 million of teacher projects from over 100,000 teachers, impacting over 10 million students.

The 1996 book Competing for the Future by the late Professor C.K. Prahalad and his colleague, Gary Hamel from the London Business School, was unique in that it tied together several of Hamel and Prahalad's leading ideas into book format. The book introduces the concept of "core competencies," which emphasizes that organizations should focus on leveraging their inherent strengths and unique capabilities, and "strategic intent," which focuses on setting an ambitious, long-run vision for a firm's future. This emphasis on future thinking was a particularly notable aspect of the book. In general, the book advocated for a proactive approach to strategy where businesses actively envision and shape the trajectory of their respective industries instead of merely reacting to existing competitors and market dynamics in the short run. This emphasis on dynamics -- in particular, envisioning the future and then mobilizing strategy to compete in shaping it -- had important managerial implications for business thinking in the 1990s.  It suggested that companies needed to transition from a short-term, reactive mindset to a more forward-thinking, visionary stance; this would allow companies not just to survive but dominate in future market landscapes. Overall, this book had a notable impact on business practice; Time Magazine named it one of "The 25 Most Influential Business Management Books."

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.

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 the early 1990s, Professor Garry Brewer became dean of the U-M School of Natural Resources and the Environment. He approached Dean Joe White of the Michigan Business School with the concept of a dual-degree program to prepare future business leaders with an integrated education in both earth and management sciences. The concept took shape first in 1993 in the form of a graduate dual-degree program (originally called the Corporate Environmental Management Program) under the leadership of Professor Stuart Hart and then the Erb Institute after a generous grant from Fred and Barbara Erb in 1996 and a series of additional donations from other visionary donors. The dual-degree program was then incorporated into the Erb Institute and bolstered by the scholarly research of three newly endowed professorships. Nearly 30 years later, the Erb Institute has expanded dramatically to become a full-fledged, endowed institute with three chaired professors, an undergraduate Erb Fellows Program, more than 200 graduate and undergraduate students, and more than 750 alumni across 17 countries. In addition, the institute has an active agenda of scholarly and applied research and works to facilitate business engagement through business roundtables and global conference partnerships. Today, the Erb Institute is generally recognized as the leading business sustainability institute for research, teaching, and business engagement.

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.

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.

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.

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.

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."
