PERIODICALS.

This article presents abstracts of article in Italian periodicals by Robert F. Foerster and of articles in Danish and Swedish periodicals by R.S. Saby. One of the articles is a criticism of Bohm-Bawerk's whole theory of valuation. Holding a cost theory himself, O. Conrad thinks the author of the "Positive Theory" is completely turned around in his very formulation of the problem. In yet another article it says that the economist should have the "social point of view." But his concept of society need not be as broad as that of the sociologist. He deals with the strictly economic aspects of social cooperation. Another article is highly ingenious developments of geometrical and algebraic methods, starting with a modification of Edgeworth's "curves of indifference." One of the most interesting results is a new sort of demand curve for which the assumption that the value of money is constant is not necessary. It is not clear, however, that these new methods can lead to new conclusions of any real significance. Another article is on Brentano's social and economic views, suggested by the successful effort made by Brentano in 1912 to silence by legal process certain detractors who were misrepresenting his views on labor and wage questions.
