110 SOCIAL SCIENTIST The 'classic* questions of value and distribution are discussed in the second group of essays titled Wages and Profit. For students of this area an essay that reexamines the Marxian dichotomy of values and rte prices of production in the presence of ground rent, and one that examines Bohm-Bawark on the positive rate of interest in a stationary state are of considerable interest* A third group of essays deal with the theories of international trade and investment. An essay that relates Ricardo's comparative cost doctrine to Emanuel's unequal exchange places both in a somewhat novel perspective. The last group of essays on markets and money discusses the early microeconomists like Jevons, Edgeworth, Cownot, Monger and finally Marshall to explore the possible microfoundations of macroeconomics and monetary theory. As mentioned above, what is common in these essays that scan ideas originating over a period of two hundred years is that none of them use the Walrasian market paradigm. For economic theory this is a significant unifying theme because it enables the reader to have a glimpse of the variety and the richness of the constructions used by authors as diverse in ideology and chronology as Smith, Marx and Keynes—outside what is now surprisingly regarded as the mainstream of economic tradition. Particularly for the students of the nineties to whom a rigorous construction is synonymous with a Walrasian construction (with or without the auctioneer), and the other traditions are interesting only to the extent that they often provide the same kinds of conclusions, a book like this can be quite revealing. There is no denying the elegance of the Walrasian structure, so much admired by Joseph Schupeter, but it is vital to point out how often the elegance has been bought at the cost of abstracting from such problems of the economic reality that we may ignore only at our own peril. We thank Negishi for producing this small volume which may help us awaken to the rich varieties of analytical constructions we economists inherit, and are yet forgetful about.
