Intertemporal competitive equilibrium: a reappraisal of a basic source of instability

Sergio Parrinello

MPRA Paper from University Library of Munich, Germany

Abstract: Abstract This paper resumes a source of instability of intertemporal equilibrium which was anticipated by Garegnani (2003) and criticized by Schefold (2004). The author points out that a non orthodox tâtonnement pricing must be accepted if the theory has to be consistent with the Jevons’s law of unique price. Such tâtonnement prescribes that the rule for adjusting the relative prices of commodities available at different times is different from the rule applied to the relative prices of contemporary commodities. The working of such a mechanism can be a fundamental source of instability of the intertemporal equilibria. This result seems to be a challenge for the stability of general equilibrium also in the context of more realistic nontâtonnement disequilibrium processes.

Further development: S. Parrinello, Numeraire, Savings and the Instability of a Competitive Equilibrium”, Metroeconomica 62:2 (2011) 328–355.
