Professor Hugh Stanley Emrys Gravelle studied at the University of Leeds (September 1963-June 1966), where he graduated in BComm.
He joined the staff at Queen Mary College, University of London, lecturing in theories and applied microeconomics.
Most economists probably know him as the lead author with Ray Rees, of the standard intermediate text: Microeconomics, Prentice Hall, 1981, First Edition.
An application of Gravelle et al. welfare theorem is exemplified in Market Failure.
One of Professor Gravelle's theory of health and unemployment was discussed in a recent book by Davide Stucker and Sanjay Basu.
