Hayek's career raises many puzzles and sometimes takes on the appearance of an endless trail of unresolved or only partly resolved issues. - Mark Blaug

Despite entries on socialism, socialist economics and market socialism, and biographical entries on Oskar Lange and Ludwig von Mises, the Socialist Calculation Debate, so crucial in the revival of general equilibrium theory and the rise of modern welfare economics in the 1930s, is nowhere discussed at length in The New Palgrave.

Joan Robinson's much-awaited textbook in “modern economics” perfectly exemplifies the typical attitude of Cambridge economists to micro-economics. The whole of traditional price theory is covered in one chapter … [some] prices are formed by conventional mark-ups on prime costs, the level of the mark-up itself being left unexplained. Apart from this chapter, the book is doggedly macro-economic in treatment … A striking omission from the book is any mention of the closely related concepts of externalities and public goods, which most economists would nowadays regard as the basic ingredients of “market failure” that has come to be fruitfully applied … to problems of pollution and congestion.

Nothing is more difficult than to turn and entire discipline around, asking itself to jettison its own history over the last 200 years.
