Philippe Michel (6 October 1937 – 22 July 2004) was a French mathematical economist.
[2] Philippe Michel first scientific contributions were in the field of mathematics, with a focus on optimal control theory.
Second, when the social optimum has been characterized, its decentralization can be achieved in various frameworks where different types of frictions or externalities may come from environment, education, money, etc.
Jean-Michel Grandmont [de] published an obituary[2] stressing that his prolific scientific contributions were a reflection of his character: original and deep thinking, intellectual honesty.
The role he played in advising numerous young researchers over the years has led his friends to honor him through the award of a young researcher prize for the best paper on economic dynamics on the fifth anniversary of his death.
