We propose a measure of technological progress based on the information embedded in standard input-output tables. A connection is established between the quantities necessary as inputs, the associated output and auxiliary prices. It is argued that the wage-profit frontiers and the associated...

Standard postulates concerning the aggregate production function are about marginal productivities - and the associated demand of labor and capital – which are to be negatively related to factor prices, namely the wage rate and the profit rate. The theoretical cases in which these neoclassical...

The Hahn-Banach Theorem plays a crucial role in the second fundamental theorem of welfare economics. To date, all mathematical economics and advanced general equilibrium textbooks concentrate on using nonconstructive or incomputable versions of this celebrated theorem. In this paper we argue for...
