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.

Michigan Business School Professor and Erb Institute Faculty Director,Tom Gladwin, pioneered the field of business sustainability with his concept of a "science of sustainable enterprise." It was one of the first scholarly frameworks to bring together the social, environmental, economic, and organizational aspects of competitive companies that likewise are managed to explicitly create value for society. With groundbreaking publications like "Shifting Paradigms for Sustainable Development: Implications for Management Theory and Research" and "Beyond Eco-Efficiency: Towards Socially Sustainable Business" in the 1990s, Gladwin dramatically expanded the scope of traditional management education and business leadership. Throughout his career, and his long-time partnership with the Prince of Wales's Business & the Environment Programme, Gladwin influenced hundreds of CEOs and other top corporate leaders to think deeply about, and take action on, the threat and the opportunity of sustainable business. 

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.

The Carson Scholars Program at Michigan Ross is a signature feature of the Ross BBA Program and a result of the vision and generosity of David Carson, BBA '55. Carson, the former president of People's Savings Bank in Connecticut, was recognized by Forbes as one of the 500 most powerful people in the corporate United States. Based on his experiences throughout his career, Carson realized that future business leaders should understand how government works to develop effective corporate strategies for participating in the public policy arena. As a result, CSP enables Ross undergraduates to augment their on-campus learning with study in Washington, D.C., where they meet with elected officials, government experts, industry leaders, issue advocates, and lobbyists. Since its foundation in 2005, the program has enabled more than 1,000 alumni to learn about the public policy process from these experts.

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 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.

From 1990-1993, Michigan Ross housed the Minority Summer Institute with support from the Association to Advance Collegiate Schools of Business and the Graduate Management Admission Council. MSI was designed to increase the number of minority faculty in business and management education. 

Each year, 30 Black, Hispanic, and Native American college students were selected to participate in MSI's six-week program. While at Ross, the students were involved in a series of classes, informational sessions, and presentations that provided a first-hand introduction to doctoral studies and the life and work of business professors. 

According to Dave Wilson, former president of GMAC, "When one thinks about changing the world, the MSI initiative must be seen as a resounding success." Following the last offering of MSI, the KPMG Foundation initiated the PhD Project, which has continued the mission of MSI. The PhD Project reports that the number of underrepresented business professors in the United States has risen from 294 in 1994 to more than 1,700 today.

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.

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 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."

The fields of social movements and organizations had very little overlap until Professors Jerry Davis and Mayer Zald convened a pair of conferences at Michigan Ross in 2001 and 2002 that brought together top scholars from both domains and forged research collaborations that yielded a 2005 Cambridge University Press volume and a 2008 special issue of Administrative Science Quarterly. Zald had previously published a piece on the topic in 1977, as had Davis in 1994. Today, this is a widely recognized and fruitful research domain that arose just in time to explain the increasingly prevalent interplay between corporations and social movements, including boycotts, corporate political activism, and employee social movements.

Since an article she published in the Iowa Law Review in 1995, Professor Dana Muir has worked in the field of fiduciary obligation, particularly as it relates to the investment of the almost $37 trillion in U.S. retirement assets, but also as it relates to a variety of other employee benefit plans. In her 1995 article, Muir explained that the courts' attempts to define fiduciary obligation using concepts from fourteenth-century trust law were misguided. Muir has subsequently addressed fiduciary concepts in the context of investment advice, the extent to which employers serve as fiduciaries of the plans the sponsor, and, most recently, in their application to the consideration of environmental, societal, and governance factors in the investment of retirement fund assets.

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.

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.

In 2002, Professor Ravi Anupindi and his co-authors published the influential paper "Coordination and Flexibility in Supply Contracts with Options" in Manufacturing & Service Operations Management. This work introduced an innovative model that integrated options into supply contracts, offering enhanced management of demand uncertainties in supply chains. The research highlighted the important potential role of options in attaining contractual flexibility to coordinate supply chain participants and improve overall efficiency. The paper influenced subsequent research on supply contract design and demand management, one of the major areas of supply chain management research in the past two decades.
