His pioneering research on organizational theory, started at Rochester, has left an enduring mark on the academic and business worlds.
ItÌÇÐÄ´«Ã½™s hard to overstate the effect economist , the former LaClare Professor of Finance and Business Administration at the , has had on his field and beyond. His pioneering research not only revolutionized the understanding of corporate finance and organizational theory, but also changed the way companies are run.
Jensen, who taught at the UniversityÌÇÐÄ´«Ã½™s for two decades from 1967 to 1988, died this month. He was 84.
During his tenure at Rochester, Jensen cofounded one of the most prominent peer-reviewed academic journals, the . He also established the UniversityÌÇÐÄ´«Ã½™s Managerial Economics Research Center in 1977, serving as its director before leaving for Harvard University in 1988, where he was eventually named a professor emeritus.
In the world of academia, a high number of citationsÌÇÐÄ´«Ã½”when other academics cite your researchÌÇÐÄ´«Ã½”is a quantifiable measure of success. Having an invention or idea named after you, and seeing it widely used, is another. Jensen had both.
His total body of work, spanning a handful of books and more than 100 academic papers, racked up more than (as of April 2024), making him one of the most influential financial economists of all time. In the late 1960s, he developed what came to be known as , a method for calculating the performance of mutual fund managers.
Jensen had fans and detractors. In , a columnist for Bloomberg Opinion,Ìýhis critics deemed him ÌÇÐÄ´«Ã½œthe high priest of the greed-is-good era who justified exorbitant executive pay and vulture capitalism,ÌÇÐÄ´«Ã½� while his admirers saw ÌÇÐÄ´«Ã½œthe surgeon who gave Anglo-Saxon capitalism a new lease of life by slicing off the fat, removing the malignant tumors and prescribing a strict exercise regime.ÌÇÐÄ´«Ã½�
Shooting to economic stardom with the ÌÇÐÄ´«Ã½œtheory of the firmÌÇÐÄ´«Ã½�
In 1976, Jensen published a seminal paper coauthored with the late , then-dean of the Simon School. Neither could have foreseen that the publication, titled ÌÇÐÄ´«Ã½œ,ÌÇÐÄ´«Ã½� would become the single in business academia.
In the paper, Jensen and Meckling describe a model in which the owners of a company (the ÌÇÐÄ´«Ã½œprincipalsÌÇÐÄ´«Ã½�) hire executives (the ÌÇÐÄ´«Ã½œagentsÌÇÐÄ´«Ã½�) to steer the company on their behalf. They argued that conflict, especially over costs, was baked into the system, unless the incentives were such that the agents wouldnÌÇÐÄ´«Ã½™t try to take advantage of the principals.

Their solution? Make top executives hold an equity stake in the company they helm so that they, too, had a vested interest in the corporationÌÇÐÄ´«Ã½™s financial success, trimming away managerial excessesÌÇÐÄ´«Ã½”and sometimes parts of the workforce.
Or as Wooldridge noted plainly: ÌÇÐÄ´«Ã½œThe more you turn ÌÇÐÄ´«Ã½˜agentsÌÇÐÄ´«Ã½™ into ÌÇÐÄ´«Ã½˜principals,ÌÇÐÄ´«Ã½™ the more you will give them an incentive to squeeze the maximum value out of the companies that they were hired to run.ÌÇÐÄ´«Ã½�
Jensen and Meckling posited that as the top managersÌÇÐÄ´«Ã½™ ownership stakes increased, their interests became more aligned with the interests of the shareholders. It was this central argument, developed further with JensenÌÇÐÄ´«Ã½™s long-time colleague and collaborator , that laid the foundation for the widespread use of stock options as executive compensation tools (which has since become a standard component of top managersÌÇÐÄ´«Ã½™ pay packages).
ÌÇÐÄ´«Ã½œHis old classmates at Chicago just thought he was nuts,ÌÇÐÄ´«Ã½� says Murphy, now a professor of finance and business economics at the University of Southern CaliforniaÌÇÐÄ´«Ã½™s Marshall School of Business, about the business school where Jensen received an MBA and a PhD. ÌÇÐÄ´«Ã½œThe Chicago way of thinking was that the market should solve everything, and that weÌÇÐÄ´«Ã½™ll get to efficiency, as long as the markets are working well. But Mike and Bill disagreed.ÌÇÐÄ´«Ã½�
Nearly fifty years later, the paper remains ÌÇÐÄ´«Ã½œfundamental to understanding the dynamics of modern corporations,ÌÇÐÄ´«Ã½� notes , SimonÌÇÐÄ´«Ã½™s current dean and a professor of business and economics. ÌÇÐÄ´«Ã½œMike will be remembered not only for his intellectual brilliance but also for his unwavering commitment to advancing knowledge that transformed the way we perceive and practice economics and finance.ÌÇÐÄ´«Ã½�
Described by those who knew him as ÌÇÐÄ´«Ã½œa force of natureÌÇÐÄ´«Ã½� who brought an ÌÇÐÄ´«Ã½œamazing energyÌÇÐÄ´«Ã½� to whatever he undertook, Jensen slept little and rose early. Starting his workday at 4 or 5 a.m., he was known to take short afternoon power naps in his office.
Work was his passion. So were the outdoors. Another one was collecting fine wine.
The proud owner of two large wine cellars in Vermont, one in his main house and another in the guest house, Jensen also had several large wine cabinets installed at his Florida residence. According to friends, even while sipping exquisite wines, his notion of good conversation invariably returned to ideas and economics.
A 40-year collaboration, originating at Rochester
MurphyÌÇÐÄ´«Ã½™s and JensenÌÇÐÄ´«Ã½™s four decades-long professional collaboration started at Rochester, when MurphyÌÇÐÄ´«Ã½”a young assistant professor on his first jobÌÇÐÄ´«Ã½”cowrote an op-ed for the New York Times with Jensen, who by then was already the Simon SchoolÌÇÐÄ´«Ã½™s undisputed superstar.

Other coauthored papers followed, including ÌÇÐÄ´«Ã½œÌÇÐÄ´«Ã½� in 1990. ÌÇÐÄ´«Ã½œWe felt that following the stock price was the right thing to do,ÌÇÐÄ´«Ã½� says Murphy, explaining their underlying idea that managers needed to be paid, at least partially, in equity or stock options to maximize shareholder value.
But there was a flipside when CEO pay reached stratospheric heights. Jensen and Murphy had advocated for an increase in stock options for the top brass in return for a reduction in other types of compensation. ÌÇÐÄ´«Ã½œWhat actually happened, to our chagrin, was that companies would layer stock options on top of existing competitive pay packages.ÌÇÐÄ´«Ã½�
Frequently fellow academics, labor unions, or the public at large disagreed with Jensen, who considered takeovers (and hostile takeovers) a fundamentally efficient way to unleash value. He also saw the positives of golden-parachute arrangements that would effectively bribe executives not to resist such takeovers.
At one point, Murphy and Jensen embarked on a hot-button book project with Eric Wruck, who earned an MBA at Rochester, titled CEO Pay and What to Do About It. Due to be published by Harvard Business School Press, the work-in-progress attracted early media interest in 2007, including from the .
°Â°ù³Ü³¦°ìÌÇÐÄ´«Ã½™s stalled progress on the project, although Jensen and Murphy continued to work on it until 2018. Ultimately, the book failed to come to pass, its chapters appearing instead as a series of academic articles.
In what would have been the last chapter, they warned Congress, in so many words, to butt out: ÌÇÐÄ´«Ã½œ is that the best way the government can fix executive compensation is to stop trying to fix it, and by undoing the damage already caused through existing regulations that have, in aggregate, imposed enormous costs on organizations, their shareholders, and social welfare.ÌÇÐÄ´«Ã½�
Putting integrity back into finance
Later in life, Jensen added another dimension to his researchÌÇÐÄ´«Ã½”the idea of integrity through the lens of corporate accountability.
In the wake of the infamous corporate fraud cases and subsequent implosions of Enron and WorldCom in the early 2000s, followed by the global financial crisis of 2008, Jensen began advocating for a change in corporate behavior. In 2012, together with Werner Erhard, he that integrity was ÌÇÐÄ´«Ã½œas important as labor, capital, and technology. Without a clear, concise, and most importantly, an actionable definition of integrity, economics is far less powerful than it can be.ÌÇÐÄ´«Ã½� The same, the duo wrote, applied to finance and management.
Aware that this position could be perceived as a departure from JensenÌÇÐÄ´«Ã½™s earlier research, the coauthors cautioned readers that because their intention was to ÌÇÐÄ´«Ã½œcall attention to aspects of life and aspects of finance that are not commonly discussed, or certainly not discussed in the way we will do so here, you are likely to find it strange and even wrong.ÌÇÐÄ´«Ã½�
An enduring legacy, including as a colleague, mentor, and teacher

JensenÌÇÐÄ´«Ã½™s influence on the academic and business worlds is undisputed.
Several faculty members at Simon, including ,Ìý,Ìý,Ìý,Ìý, and , were close colleagues of JensenÌÇÐÄ´«Ã½™s. All of them have become influential in their own right, carrying forward his legacy of groundbreaking research and innovative thinking.
Jensen also left a lasting impression as an educator. Throughout his career, JensenÌÇÐÄ´«Ã½™s teaching and mentorship inspired countless students and colleagues, many of whom went on to build their own successful careers in academia.
One of them is , now a professor of finance at Ohio State UniversityÌÇÐÄ´«Ã½™s Fisher College of Business (and Eric °Â°ù³Ü³¦°ìÌÇÐÄ´«Ã½™s widow). Wruck, who received a PhD at Rochester and initially had followed Jensen to Harvard, describes him as ÌÇÐÄ´«Ã½œthe most intellectually curious and creative personÌÇÐÄ´«Ã½� she has ever worked with. She credits Jensen with teaching her how to ÌÇÐÄ´«Ã½œthink critically without being closed-minded, and to never give up.ÌÇÐÄ´«Ã½�
Wruck adds, ÌÇÐÄ´«Ã½œNot a day goes by that I do not use some idea, concept, or way of thinking that I learned from him.ÌÇÐÄ´«Ã½�
