Philip Hallen Dybvig, known simply as Philip Dybvig, is an American economist and Nobel Laureate.
He is one of the sharpest minds when it comes to modern economics and most recently won the 2022 Nobel Memorial Prize in Economic Sciences.
He is also the Boatmen's Bancshares Professor of Banking and Finance at St. Louis's Washington University's Olin Business School.
In economics, he is known for his work on the Diamond-Dybvig model of bank runs that he worked on with fellow economist Douglas Diamond. His work on this model of bank runs won him the Nobel prize alongside Douglas Diamond and another economist, Ben Bernanke.
The committee stated they'd won for research on banks and financial crises. The 67-year-old is well-equipped in economics and has an extensive base of studies, having both an MPhil and a Ph.D.
As far as the public knows, economist Philip Dybvig is not married nor does he have a partner.
Though much is unknown about the man, given that he was a relatively obscure figure in the mainstream before his Nobel prize win, now that he has become more popular he has become subject to much scrutiny.
The public, especially the American public, wants to know more about their newest Nobel laureate, and when looking at Dybvig's life has found a man who is completely involved with the world of economics.
There is no indication that Dybvig is married or has a partner, and if he does then he has hidden them from the public very well to the point that there are no traces they even exist.
When talking about his personal life, the economist has stated that he spends his leisure time playing and composing music.
Though he hasn't specified what sort of music he likes to play and compose, one assumes it is in the classical genre given his pedigree and his educational background.
He is also a big fan of cooking, and seems to take it very seriously as one of his other hobbies is lifting weights.
Looking at his physique, one can see that Dybvig not only takes very good care of his body, but he has the physique of a powerlifter.
With both lifting weights and cooking as his hobbies, he probably keeps a tight tab on what he eats and how he handles his body.
He is also a dedicated practitioner of TaiChi.
Born on May 22, 1955, Nobel Laureate Philip Dybvig has been an academic all of his life.
However, his bachelor's degree was not in economics, and he earned a Bachelor of Arts degree in Mathematics and Physics when he graduated from Indiana University in 1976.
Things changed and his interests turned to economics for his master's and he studied economics at the University of Pennsylvania and Yale University.
He received an M.A. and M.Phil degrees in 1978 from Yale, and he quickly earned a Ph.D. in the subject the next year.
Straight after earning a Ph.D., he started teaching economics at Yale University in 1979, then Princeton University from 1980 to 1981.
He has been teaching at Washington University since 1988 and even taught at Chengdu, China's Southwest University of Finance and Economics from 2010 - 2021.
His time at the Chinese university was spent with him being very beloved as the university bemoaned his loss just shy of a year before he won the Nobel prize.
Many sources in Chinese media have stated that the economist was the closest a Chinese university ever came to a Nobel prize.
It was during his tenure at Washington University that he was lauded with the honor of being named Boatmen's Bancshares Professor of Banking and Finance in 1990.
Aside from his work in teaching, Dybvig has also been the president of the Western Finance Association for a year from 2002 to 2003.
From 2010 to 2021, he was also the director of the Southwest Unversity of Finance and Economics Institute of Financial Studies.
He has also been the editor or associate editor of many economic journals.
Philip Dybvig, alongside Douglas Diamond and Ben Bernanke, won the Nobel prize for the Diamond-Dyvbig model.
The Diamond-Dyvbig model is a model of bank runs and financial crises that has become very influential since its initial publication in 1983.
This model shows how a mix of illiquid assets in banks, such as business or mortgage loans, alongside liquid liabilities like deposits that can be withdrawn at any time, could give rise to widely self-fulfilling depositor panic.
The intention of his paper at publication was to show how a financial institution with short-maturity liabilities and long-maturity assets can be unstable.
The crux of the paper was the fact that business investments need present expenditures to gain future returns, and as such, what they chiefly prefer are loans with long maturity and low liquidity.
This principle also applies to people seeking financing to purchase larger items and investments like housing and automobiles.
The same applies to people who can have sudden and unpredictable needs for cash due to largely unforeseen expenditures.
When this happens, they will demand liquid accounts permitting immediate access to their deposits.
What the Diamond-Dyvbig model states are that this uncertainty can often lead to financial ruin and bankruptcy.
It further states that unless the total amount of actual expenditure is known with complete certainty, there cannot be an optimal mechanism for preventing bank runs.
Their solution was a central or government bank that prevents bank runs through deposit insurance.
This insurance will pay depositors all or some part of their losses if a bank run ever occurs.
This method ensures that, since depositors know they will get their money back if a bank run happens, they will no longer participate in one.
