It is also Gerard Debreu’s birthday

Remember Theory of Value, that elegant 128 pp. book which summed up general equilibrium theory?  Here is a brief bio of Debreu, courtesy of Liberty Fund.  Here is Debreu’s own autobiography.  Here is Wikipedia. 

I recall Debreu once saying he took his inspiration from Proust.  To what extent is time a dimension just like space in its effects on human organization?  Debreu solved for those conditions, with of course assistance from Arrow, Hurwicz, Wald, and others.

And by the way, Yana just got her bag, so I feel Debreu’s model is just a little less unrealistic than it was appearing last night.
