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. Final version of this working paper: S.Parrinello, “Intertemporal Competitive Equilibrium, Capital and the Stability of Tâtonnement Pricing Revisited”, Metroeconomica 56:4 (2005). Further development: S. Parrinello, Numeraire, Savings and the Instability of a Competitive Equilibrium”, Metroeconomica 62:2 (2011) 328–355.
