This is Volume II in a series on Studies in Applied Economics and looks at the theory of the production of social wealth in the areas of agriculture, industry, commerce banking and stock markets. The two volumes form a translation from French of Walras?s two main books, Études d?économie politique appliquée (Théorie de la production de la richesse sociale) (1898) and Études d?économie sociale (Théorie de la répar[1]tition de la richesse sociale) (1896).
