Samuelson extends the Ricardian theory of foreign trade to a model of small open economies in which countries can trade semi-finished capital goods on international markets, as well as produced consumer goods. He argues that this extension provides an additional gain from trade, which he labels...

This article considers a model of international trade in which the number of produced commodities does not exceed the number of countries engaged in trade. Technology is modeled such that each commodity can be produced in each country from a finite series of dated labor inputs. The existence of...

This article extends to unequal rates of profits a derivation of prices of production from a linear program. A partition of the price-wage space is illustrated in an example with two produced commodities. The variation in the solution of the LP with perturbations of relative markups is...

The article presents previously unpublished material from file D13/12/111 in Sraffa's archives. In particular, it reproduces an English translation of Aurelio Macchioro;s review in Annali dell'Istituto Giangiacomo Feltrinelli, a summary by Christopher Bliss of a paper that he read to the...

This article illustrates the application of pattern analysis to structural economic dynamics with a choice of technique. A numerical example is presented in which technical progress is introduced. Examples of temporal paths through the parameter space illustrate variations of the wage frontier....

This article presents an analysis based on a comparison of stationary states. With technology and relative markups among industries taken as exogenous, the long-period trade-off between wages and rates of profits is determined. A long-period change in relative markups among industries can create...

Paul A. Samuelson extends the Ricardian theory of foreign trade to a model of small open economies in which countries can trade semi-finished capital goods on international markets, as well as trade in produced consumer goods. He argues that this extension provides an additional gain from trade,...

This paper considers the application of multiple interest rate analysis to a model of the production of commodities by means of commodities. A polynomial, for the characteristic equation of the augmented input-output matrix, is used in defining the rate of profits in such a model. Only one root...

This paper clarifies the relationships between Internal Rates of Return, Net Present Value, and the analysis of the choice of technique in models of production analyzed during the Cambridge capital controversy. Multiple and possibly complex roots of polynomial equations defining the IRR are...
