Economics New Classical Versus Neoclassical Frameworks

This innovative text ushers in a new way of examining basic economic issues. It teaches economics from a different standpoint, based on specialization and the division of labor. Resource allocation for a given level of division of labor is shown as not the only determination for demand and supply. Levels of division of labor are shown as a major factors as well.
