The Price Index and its Extension
A Chapter in Economic Measurement
The book is not an unrestricted survey engaging a vast and repetative literature, but a systematic treatise within clear boundaries, largely a document of Afriat's own work. The original motive of the work is to elaborate a concept of what really is a price index, which, despite some kind of price-level notion having a presence throughout economics, in theory and practice, had been missing.
S. N. Afriat currently associated with the University of Siena, Italy, has a long and distinguished record of publishing at the interface of mathematics and economics. His most recent book The Market: Equilibrium, Stability, Mythology is also published by Routledge (2003).
