Pure joint production and international trade: a note

Theodore Mariolis ()

Cambridge Journal of Economics, 2004, vol. 28, issue 3, 449-456

Abstract: This paper applies the principles of the neo-Ricardian (or Sraffian) theory of international trade to certain joint production systems. It is shown that, in contrast with single-product systems, (i) there is not always a pattern of international specialisation, which would entail the increase of the real wage rate in both economies, and (ii) the 'law of comparative advantage' has no general validity. Furthermore, not only the existence of such a pattern of specialisation but also the validity of this law depend on the values of the variables of distribution of income. The analysis is wholly based on two of the numerical examples formulated by Bidard in 1997, and further generalised in an elementary way only when this is considered necessary.
