Following the decision of Dobbs v. Jackson Women's Health Organization by the U.S. Supreme Court, abortion restrictions within the United States have proliferated, and it is reasonable to expect that access to abortion services will be even further reduced in the future. The work of Associate Professor Sarah Miller investigates the impact of abortion denial using new linkages between data from the Turnaway Study and administrative records in credit reports. The Turnaway Study was a path-breaking study from the University of California San Francisco that recruited women seeking abortions, some of whom had pregnancies that just exceeded the gestational age limit of the clinic they attended and were denied abortions, others who fell just below this limit and were able to receive the abortion they sought. Miller and her co-authors found that women denied an abortion and those who received an abortion were on similar trajectories before the denial, but those denied an abortion experienced a large spike in financial problems such as unpaid bills and public records (such as bankruptcies and liens). This spike in financial problems persisted for the full six-year follow-up period that the authors had access to. The results provide evidence counter to the narrative that abortion is exclusively harmful to women who receive one (because of, for example, the regret they may feel after receiving an abortion). Instead, it suggests that giving women control over the timing of their reproduction allows them greater financial stability and self-sufficiency.
The paper "Quantity Flexibility Contracts and Supply Chain Performance" by Professor Bill Lovejoy and his colleague, Andy Tsay from Santa Clara University, was published in Manufacturing & Service Operations Management in 1999. The paper delves into the concept of quantity flexibility in supply chain contracts and its potential to deal with demand uncertainties. This influential work formally captured the practice of “funneling” variability over time, whereby more variability is tolerated in earlier planning phases and less tolerated over time as the delivery date approaches. This paper has specifically led to further studies on the optimal design and effectiveness of supply chain contracts, enhancing the field’s understanding of tactical and strategic issues in supply chain management. Researchers have built on Tsay and Lovejoy's model to study the application of QF contracts in different industrial contexts and their interactions with various supply chain configurations. The concept and modeling presented in this paper have become a prominent part of the academic discourse on supply chain coordination, influencing subsequent studies in inventory management, order variability, and supply chain profitability. Thus, the paper's impact is significant and broad, inspiring much-needed research on flexible, cooperative strategies for supply chain optimization.
From 2000 to 2005, Professors C.K. Prahalad and M.S. Krishnan co-authored several papers on concepts related to how the emergence of digital technologies was transforming business models. From 2005 to 2008, they co-authored the book New Age of Innovation, which introduced the concept of N=1;R=G business model framework. The basic argument was that given the new capabilities emerging from digital technologies, the structure of business models was in the midst of a transformation across industries. They claimed that business models will shift from mass production of products or services to businesses co-creating personalized experiences for one customer at a time. They called this N=1 business model, i.e., businesses will operate on a sample size (N) of one. They argued that to orchestrate this personalized experience for one customer at a time, businesses will not own all resources but will connect with resource partners across the globe (Resources=Global or R=G), and these partners could be big organizations, small businesses, entrepreneurs, or even individuals. They called this business model N=1;R=G. They argued that digital technology was at the center of enabling these capabilities, and no industry will be immune to this change. They presented more than 80 examples in the book. The rest of the book was on the capabilities companies needed to build inside their organizations to compete as an N=1 business. Their primary thesis identified the significant role of software in orchestrating the personalized N=1 experience in an ecosystem of partners and the criticality of the right capabilities in the information architecture and social architecture of companies to thrive in this competition of N=1;R=G ecosystem business models.
Established by Samuel Zell and Ann Lurie in 1999 as the first entrepreneurial studies program at the University of Michigan, the Zell Lurie Institute for Entrepreneurial Studies plays a vital role in developing the next generation of entrepreneurs and venture investors. The Institute offers various programs, competitions, and academic courses that give students the knowledge, skills, and motivation to develop a growth mindset and succeed as entrepreneurs.
Since its inception, the Institute has supported more than 9,100 entrepreneurs. It provides students with hands-on experience in entrepreneurial environments where they create, lead, and shape innovative ventures.
The Institute also supports venture investing and plays a key role in connecting entrepreneurs with venture capital and grant funding. This access to funding is crucial for entrepreneurs looking to start or scale their businesses and allows Ross students to act as real venture capitalists.
In the 1990s, a research team at Michigan Ross, led by Emeritus Professor Claes Fornell, created the American Customer Satisfaction Index. This groundbreaking project included Professors Eugene Anderson and Michael Johnson, as well as Research Scientist Jaesumg Cha and Barbara Everitt, former director of the U.S. Census Bureau.
ACSI represents a paradigm shift in measuring market performance, offering a more complete view of firms, industries, and economies and treats customer satisfaction as a latent construct connecting expectations, perceived quality and perceived value, through customer satisfaction, to customer voice and loyalty. For the past three decades, ACSI has catalyzed a wealth of peer-reviewed research in marketing and business. Empirical studies consistently find ACSI positively associated with profitability, cash flows, stock returns, credit ratings, positive earnings surprises, revenue, gross margins, return on investment, cash flow stability, and operating margins. Greater ACSI is also associated with lower cost of capital, cost of debt, and selling costs. At a macro level, ACSI is found to be predictive of gross domestic product.
Published research by the ACSI team enjoys wide recognition, garnering more than 100,000 citations. Additionally, ACSI-related research has played an outsized role in establishing customer satisfaction as an essential metric within firms' management information systems, priority setting, and key performance indicators.
In 2021, Assistant Professor Andreas Hagemann developed a new econometric methodology that addresses the complexities of clustered data to enhance the accuracy and reliability of empirical work in economics and related fields. Typical examples of clusters are firms, cities, or states. The central challenge is that units within clusters may influence one another or may be influenced by similar environmental factors in ways that cannot be observed. Empirical researchers know that neglecting to account for clusters can yield results where non-existent effects erroneously appear as highly significant. Hagemann's research agenda developed new tools to address this issue in challenging and empirically relevant scenarios. His work has had a substantial impact on econometric theory and empirical practice. For instance, the methodology he developed is now the standard option for clustering in the canonical implementation of quantile regression in the statistical programming language R.
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.
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 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 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.
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.
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 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.
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.
As the worlds of trade and culture were globalized in the 1980s, consumers worldwide saw standardized global brands enter and grow in their local markets, displacing local brands that had been dominant for decades. But what were consumers seeing in these global brands, and why were consumers switching to them? How could local brands fight back? These timely and important questions were addressed in a series of research papers by Michigan Ross Professor Rajeev Batra and his co-authors from 1999 through 2019. They showed that if consumers perceived brands as being global, they assumed these brands were of higher quality, capable of bestowing more prestige and status to their buyers, and would bring these buyers closer to the imagined lifestyles of consumers in the home countries of these brands. These papers have been cited over 6,000 times, have been nominated for and won multiple best-paper awards in journals and societies of international marketing, and have been included in lists of the 10 papers in the last 30 years that have made the most contribution to the international marketing literature. Today, as the lure of globalization seems to be receding and local brands seem to be winning again, this work highlights the tensions and trade-offs at play.
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.
