Last Monday I got the book by Professor Thijs ten Raa (2005) The Economics of Input-Output Analysis. I like it. It's a very nice work, that provides a broad outlook about the Input-Output Analysis, and related issues: multiplier effects, linear programming, changing coefficients, National Accounts, efficiency, production functions, international trade, Environment, productivity and spillovers, dynamic inverse and stochastic IO Analysis. By the way, in this last chapter the work of our colleague of the Spanish Input-Output Group, Jos? Manuel Rueda Cantuche, is quoted. The presentation of the book is excellent. And it is not too expensive.
It is only a suggestion...
