This paper should begin with a series of disclaimers. It cannot pretend to be an analysis of all of Trotskii's ideas on economics and the economy, because this would call for a long book and because this author has not gone through the Trotskii archives or read all relevant published works. There is plenty of room for much more research on these matters, and I hope that Baruch Knei-Paz's admirable book on Trotskii's political ideas' will be followed by one that “reconstitutes” the great many fragments in which Trotskii's economic ideas are presented. Trotskii was not a professional economist, any more than Lenin was, but he did have much to say on economic affairs. What I shall do here is describe and analyze some of Trotskii's more important opinions and pronouncements.
