Capital Theory and the Rate of Return.

"These three lectures in the volume under review consolidate and extend Robert Solow's previous examination of the relationship between capital and economic growth. What is crucial is to know the social rate of return on investment; this is the principal theme, and a sound one. Readers of Solow's articles on capital and growth will surely wish to continue with this book. It is also a particularly good introduction to the discussion; prepared for oral delivery, the presentation seems easier to follow than his previous contributions. It would be an injustice, however, to imply that these lectures are merely one more contribution to the current debate over capital and growth; they are more than that. This review can scarcely suggest the breadth of the discussion or the elegance of the theoretical analysis and manipulation of simple models; suffice it to say that the whole volume is highly stimulating" (Denison, American Economic Review).
