John Geanakoplos and His Researches

John Geanakoplos is an economist who worked with Paul Klemperer and Jeremy Bulow in the 1980s and played a significant role in developing and inventing the concept and terminology of Strategic Complements, which is widely used in game theory, industrial organization, and other fields.

Before the financial crisis of the late 2000s, Geanakoplos was known for his significant contributions to the general equilibrium theory, particularly in the area of incomplete markets in general equilibrium theory. For example, Geanakoplos and Polemarchakis (1986) determined important asset and welfare implications in a general incomplete market model.

Since the start of the financial crisis of the late 2000s, Geanakoplos’s work on the relationship between leverage and asset prices, called the “Leverage Cycle,” has become prominent in popular and academic debates about financial market fluctuations and regulation. In 2009, Geanakoplos co-authored a study on credit cards and inflation through the Cowles Foundation with mathematical economist and Yale University professor Pradeep Dubey.
