General equilibrium in infinite dimensional economies : a truncation approach

Mostly in??nite dimensional economies can be considered limits of ??nite dimensional economies in particular when we think of time or product differentiation.?? We investigate conditions un??der which sequences of quasi??-equilibria in ??finite dimensional economies converge to a quasi??-equilibrium in the in??finite dimensional economy?? It is shown that convergence indeed occurs if the usual continuity assumption concerning the preference relations for fi??nite dimensional commodity spaces is slightly modi??fied??
