* ''Model of rational behavior for a consumer''. In this model we assume a consumer faces a choice of ''n'' commodities labeled 1,2,...,''n'' each with a market price. The problem of rational behavior in this model then becomes an optimization problem. | * ''Model of rational behavior for a consumer''.
