Trade occurs before anything happens. The number of agents who participate in trade is known and we may assume that the price of all contingent commodities is known in advance to all participants. The situation is different if demand conditions are not known before the beginning of actual trade. In this case the standard Walrasian model assumes an auctioneer who finds the market clearing prices by the following (tatonnement) process. He calls a vector of prices and asks agents to report their demand and supply for this price vector. He then checks whether markets are cleared. If not he tries another vector of prices and keeps doing it until he finds a vector of prices that clears all markets. Actual trade is prohibited until the market clearing price vector is found. This standard formulation is problematic for three reasons. First, the description of the Walrasian auctioneer is not complete. Why does he provide the public service of finding the market clearing prices? What is his objective function? A second problem arises from the prohibition of trade: Trade is not allowed until the market clearing price vector is found. Finally, and maybe most importantly, prices do not behave according to the standard Walrasian model. There is ample evidence against the “law of one price” and the effect of monetary shocks on prices occurs with a significant lag. The new Keynesian (sticky price) models reviewed in chapter 8 provide an .
