Explore the faculty research, thought leadership, and groundbreaking philosophies that established Michigan Ross as one of the world’s top business schools.
In 2007, Professor Maxim Sytch published a paper titled "Joint Dependence and Embeddedness: Reshaping Interorganizational Relationships and Exchange Dynamics." In this work, Sytch and his coauthor identify how joint dependence can shape relational embeddedness in inter-organizational relationships. Joint dependence stimulates relational closeness, collaborative action, and fine-grained information exchange between partners. These dynamics improve the performance of inter-organizational exchanges and reduce uncertainty within the relationship. Additionally, they reshape the exchange logic associated with interdependence, moving from an emphasis on power and leverage to a focus on relational embeddedness and mutual collaboration. This work has served as a potent counter to previous organizational and economic theories that associated interdependence with power, leverage, and mutual holdup. However, Sytch demonstrated that joint dependence can foster stronger bonds between exchange partners, leading to more effective exchanges without the looming threat of retaliation. Furthermore, the concept of joint dependence underscores that reducing relational uncertainty does not necessarily require less dependence on that partner. On the contrary, a mutual increase in dependence can foster relational closeness within the exchange, reducing opportunism, enhancing collaboration, and improving the performance of exchange relationships.
Originally launched by Michigan Ross Professor David Brophy and now organized and run by the Zell Lurie Institute for Entrepreneurial Studies, the Midwest Growth Capital Symposium began as an opportunity to showcase innovative Michigan ventures seeking funding and connect them with venture capitalists, angel investors, industry stakeholders, and leaders from across the nation.
Today, the Symposium provides a platform for pre-selected Midwest companies to present their business ideas and investment opportunities. These companies span various sectors, such as life sciences, healthcare, technology, food and agriculture, and energy. First held in 1980, the Symposium is the longest-running university-based venture fair of its kind, has gained recognition, and attracts attendees from across the country.
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.
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.
Professor Jim Walsh played a significant role in the development of work on individual, group, and collective cognition in organizations. Interested in managerial mistakes, Walsh wanted to know if executives’ worldviews could blind them to their decision environments. He was also interested in learning how the cognitive capabilities of both leadership teams and the organization itself could be harnessed for the good of organizations. In a 1988 Academy of Management Journal article, Walsh traced how these belief structures might or might not blind executives to their decision environments. He also considered how these belief structures may or may not combine to shape team decision-making. Therefore, he wrote a theoretical paper about these possibilities, which was published in the Journal of Management in 1986. He followed up that article with an empirical effort to measure and trace the impact of “negotiated belief structures” on decision-making (Organizational Behavior and Human Decision Processes published his findings in 1988). His thoughts then turned to the organization as a whole. He wrote a seminal paper on organizational memory, one that identified the nature of information selection, retention, and retrieval processes in organizations – for the good or ill of those organizations. That work was published in the Academy of Management Review in 1991. When interest in cognition in organizations started to grow, Walsh became a founding officer of the Academy of Management’s Managerial and Organizational Cognition Interest Group in 1990 and helped to lead that pioneering group of scholars for the first three years of its existence. Tying all of the insights and experiences together, he wrote what became something of a field-defining scholarly paper in 1995. Titled “Managerial Organizational Cognition: Notes from a Trip Down Memory Lane,” it was published in Organization Science. Today the Managerial and Organizational Cognition Division of the Academy of Management is home to more than 1,200 scholars worldwide. Citing his foundational scholarship and early leadership, the Division honored Jim with its Distinguished Scholar Award in 2020.
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.
While concerns regarding corporate financial misreporting have persisted since the early 1900s, there were no rigorous methods that academics, market participants, and regulators could use to assess the accounting quality or the potential for financial misreporting when looking at a set of financial statements. Faculty members Patricia Dechow, Ilia Dichev, and several of their co-authors in the Michigan Accounting group developed several widely used models that allow users to assess the financial reporting quality of a set of financial statements and, more importantly, allow users to detect potential earnings management. These models and adaptations of these models continue to be used today, both in research and in accounting courses.
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.
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.
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.
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.
Expanding on his dissertation thesis, completed in 2003, Professor Paolo Pasquariello's powerful insight (published in 2007) demonstrates that financial contagion (the spread of a shock from one financial market to many) could occur due to the simple, and highly plausible, heterogeneous private information of speculators about fundamentals. Financial contagion is an increasingly common phenomenon of global concern, especially during financial crises. Importantly, Pasquariello's theoretical multi-market setting rules out all the more complicated explanations of contagion --- usual suspects such as correlated information and/or liquidity and portfolio rebalancing --- while linking it to some of the main features of globalization, the expansion of and access to international financial markets.
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."
In 1998, Professor David Hirshleifer of the Michigan Business School, and two co-authors, published a paper titled "Investor Psychology and Security Market Under- and Overreactions." This paper has been widely recognized as the first explanation of the seemingly contradictory behavior in asset prices (under- and overreactions to different news) based on two well documented behavioral biases. The biases outlined in the paper are overconfidence (regarding the precision of one's private information) and biased self-attribution. The former leads to well documented evidence of long-term overreaction (price reversals), while the latter causes underreaction (momentum) in the medium term. This paper was the first widely recognized paper in finance based on departures from rational behavior and provided a compelling explanation for seemingly anomalous behavior in asset prices.
Professor Charles Laselle Jamison, a pioneering figure in the sphere of business management, spent most of his career at the Michigan Business School. Recognizing the importance of the evolving field of management education in 1936, Jamison proposed an organization dedicated to the support of high-quality research, teaching, and practice in the field. His vision led to the official launch of the Academy of Management in 1941. For this instrumental role, he became known as the "Father of the Academy of Management." With the onset of World War II, the Academy's operations were put on hold. However, they were revived in 1947 thanks to Jamison's tireless commitment. Since then, the Academy of Management has become an internationally recognized association for management and organization scholars.
Later in his career, Jamison would cement his legacy as a pioneer in the field of strategic management by publishing his 1953 textbook on business policy. The textbook was one of the first on the subject and showcased his invaluable contribution to the field.
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.
