I was doing some work today, catching up on some reading about social choice functions.  Most of the literature was written by Kenneth Arrow, for which he won a Nobel Prize (among other work on general equilibrium).  On his wikipedia page, I stumbed up on this 2009 paper Some Developments in Economic Theory since 1940.

Anyone who has taken a PhD-level micro course should read this text. It provides a concise guide to the development of modern thinking about game theory, general equilibrium theory, and mathematical economics along with a pleasantly written autobiography of Dr. Arrow.  I recommend.
