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. 

The article "Social Distancing as a Control Mechanism" by Professor James Westphal, is part of a larger stream of research that developed a more sociological perspective on corporate leadership and governance, an area of scholarship that had been largely dominated by economic perspectives into the 1990s. In a series of studies, Westphal and colleagues revealed a collection of social and psychological mechanisms by which governance policies, structures, and practices that were assumed to promote the economic interests of shareholders and other stakeholders were frequently subverted in ways that served the interests of powerful corporate elites. One such mechanism was "social distancing," a social sanction in which corporate directors who participated in governance reforms that threatened to increase board control over top management at one firm were socially isolated and even ostracized at other firms where they served on the board. They were less likely to be invited to informal meetings, and other directors were less likely to build on their comments and suggestions or solicit their opinions on strategic issues in formal board meetings. Directors who experienced social distancing, witnessed it firsthand, or were socially connected to a director who experienced it, were less likely to participate subsequently in elite-threatening actions. In that sense, the social distancing that Westphal identified parallels and anticipates the social distancing that we all learned about and practiced during the COVID-19 pandemic. But unlike social distancing during a pandemic, social distancing in corporate leadership, like the other social and psychological mechanisms that the authors uncovered, helped maintain a system that serves the interests of a powerful few rather than the many who depend on it for employment, goods and services, and wealth creation.

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 inception of the Journal of Public Policy and Marketing dates back to 1982 when it was founded by Tom Kinnear, a prominent faculty member from the Michigan Business School. Its initial name was Journal of Marketing and Public Policy. However, due to concerns raised by the American Marketing Association about potential confusion with the Journal of Marketing, it officially adopted its current name in 1983. The primary motivation behind the journal's creation was the growing interest among marketing academics in public policy during that era. During the 1970s and early 1980s, there was a growing interest in issues concerning the intersection of public policy and marketing. This interest encompassed various aspects, including advocacy for children's rights, as well as concerns related to other vulnerable groups such as the elderly, ethnic communities, and those with low income; the environmental impact of consumption and the emergence of what is now termed the "green consumer"; the adoption of energy-efficient practices by consumers following significant increases in gasoline, electric, and natural gas prices; evolving product liability doctrines that were becoming more lenient in terms of protective measures; food labeling and nutritional aspects; new consumer protection laws and measures. It is noteworthy that many of these trends are still relevant today, albeit with some shifts in emphasis, such as the increased focus on climate change.

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.

Since the COVID-19 pandemic, the public K-12 education system has faced significantly high teacher turnover and poor retention rates. Teachers have faced increasing pressure to achieve academic success while challenged with growing class sizes, reduced funding, and learning loss from the pandemic. This problem has been incredibly difficult to correct, and public school districts across the country have not been able to address it cost effectively.

In their paper, “Stopping the Revolving Door: An Empirical and Textual Study of Crowdfunding and Teacher Turnover,” Professors Samantha Keppler, Jun Li, and Andrew Wu conducted a study of data from the largest teacher crowdfunding site, DonorsChoose, to study the effect of crowdfunded projects on teacher retention. The team found that teachers are less likely to leave their schools and the state public school system when their projects are funded. Assessing teachers’ project request essays, they identified that teachers who received funding for unique projects or requested resources to improve their classroom environment had higher retention rates.

Their paper is the first to identify the effect of crowdfunding on teacher retention. It provides initial, strong evidence that the effect is positive, showing that teachers funded on DonorsChoose are 1.6 percentage points (pp) less likely to leave their schools and 1.9 pp less likely to leave the teaching profession — a 14% and 41% reduction versus baseline turnover and attrition rates, respectively.

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.

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.
 

Four student-run venture funds are currently operating at Michigan Ross, more than any other business school. Collectively, these funds manage a portfolio worth more than $10 million. These funds help students learn about investing early-stage capital by making real deals with real companies and real money. The concept of student-run venture funds has been adopted by universities around the world. 

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.

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.

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.

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 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.

William Davidson (1922-2009) was a successful global business leader and alum of the University of Michigan. He understood the value of the private sector to empower people around the world. 

After the fall of the Berlin Wall, Davidson recognized the value of educating and empowering economic decision-makers in formerly centralized economies with the tools of commercial success. Davidson partnered with U-M to create a unique institute providing consulting and training services to nonprofits, corporations and small businesses in emerging markets with the goals of economic growth and social progress. Since 1992, the William Davidson Institute (WDI) has served as a platform to introduce students to the challenges and opportunities facing firms in low- and middle-income countries. 

Over its history, the Institute has supported U-M student teams, totaling more than 1,800 students, who collaborate with business and nonprofit partners to provide analysis and develop solutions built upon the foundation of basic business principles. To ensure ongoing access to current and relevant business education, WDI Publishing also produces and distributes high-quality, cutting-edge business cases and other teaching materials, with more than 700 cases in its collection, reaching approximately 800 universities and institutions globally. 

The Institute is also home to NextBillion.net, an online platform for discussing business models and innovations that address development challenges in low- and middle-income countries. The platform reaches more than 25,000 readers a month.

The Preparation Initiative was created by Professor Emeritus Frank Yates in 2005. Yates was a champion of diversity in higher education and believed all students should have access to Michigan Ross, regardless of their preparation. The Preparation Initiative is a thriving community designed to foster the excellence and success of undergraduate business students from economically distressed backgrounds or from racial or ethnic groups historically underrepresented in business leadership. Since its inception, the Preparation Initiative has supported hundreds of students in their pursuit of a business education and now also offers mentoring opportunities for alums of the program.

"Co-creation as a revolutionary paradigm was introduced by Professors C. K. Prahalad and Venkat Ramaswamy in a series of articles published between 2000 and 2004 and an award-winning book, The Future of Competition. Their work provided a new frame of reference for jointly creating value through networked environments of increasingly digitalized experiences, going beyond goods and services, and called for a process of co-creation -- the practice of developing offerings, experiences, and unique value through ongoing interactions with customers, employees, managers, financiers, suppliers, partners, and other stakeholders. Through their work, they envisioned an individual and experience-centric view of interactive value creation and innovation.

Starting in 2005, the explosion of digital and social media, the convergence of technologies and industries, embedded intelligence, and information technology-enabled services enabled enterprises to build platforms for large-scale, ongoing interactions among the firm, its customers, and its extended network. Ramaswamy's work argued that success lies in connecting with people's experiences to generate insights and change the nature and quality of interactions. He also called for co-creation from the inside out of enterprises and their networks, as much as co-creation from the outside in, and for leaders to co-create transformative pathways.

In 2014, Ramaswamy published "The Co-Creation Paradigm", which combined the core ideas of co-creation with a call to see, think, and act differently in an interconnected world of possibilities and complex challenges to co-create a better future as individuals."
