This is a good, readable short history of economics, written in Galbraith's delightful style.
There is much erudite interpretation of economists, possibly excessively influencing your understanding of them. For example, of Ricardo:
"From the demanding exercise in understanding that [Ricardo] imposes, the reader can emerge with some freedom as to what he chooses to believe."
Malthus turns out to be a real economist, rather than a shreeking prophet, and his position alongside Ricardo is described. Negative opinion of Ricardo abounds, rather scornful of his explanations of profit. Galbraith is sly and amusing (as ever) about putting down Ricardo on account of his style:
"As others have noted, Ricardo managed in his later writing to soften positions that were originally very hard, and this has greatly helped many who have sought to find in him what they wished to believe."
However there is no mention of the theory of comparative advantage, which is odd.
There is more detail in the Penguin History of Economics, yet I prefer Galbraith, especially his discussion of the problems with Keynesianism and also the cant against monopoly; Galbraith is very clear about what modern corporations amount to, with their size, advertising and market and political power. In fact the later chapters in general are very gripping - about the post-war period, encompassing welfare, Keynesianism and its problems, the monopolistic corporation and the West's senile industries. That the book dates from the mid 1980s is actually a special perspective that I found particularly interesting.
The last chapter looking into the future from the mid 1980s is about Japan and suggests all sorts of Japanese institutions and approaches will be taken up - the opposite happened probably.
