Following the recent debates in the New Neoclassical Synthesis, the theory of monetary policy had been renewed. The method that prevails, illustrated by Woodford’s version of Interest and Prices, is a Dynamic General Stochastic Equilibrium Model (DGSE) in which the old LM curve is voluntarily substituted by an optimal monetary rule. Such a turning point requires a peculiar set of assumptions especially regarding the monetary prices. The recent debate puts attention on the de-emphasis on nominal monetary aggregate that doesn’t play any explicit role in monetary policy deliberations. Following Calvo’s model, Woodford’s neo-Wicksellian framework only considered monetary prices in equilibrium. The article demonstrates that even though the New Neoclassical Synthesis considers that it is essential to dispose a monetary theory for monetary policymaking, it offers the same answers as the traditional static macroeconomics. More precisely, we show that the use of dynamic optimization -such as the one developed by Woodford approach- does not contribute in a decisive way to improve our understanding of the role that money prices play in the monetary theory. Woodford's canvas is silent about the mechanisms whereby monetary policy induces agents to adjust individual money prices to the values that generate an equilibrium price level. Thus, if we want to close this gap, it may be useful to consider forward guidance strategy. Under such tool, central bankers are able to shape public's expectations on economic outcomes by pre-announcing of the time path of future policy actions.
