Money: Endogeneity and neutrality

This paper examines the implications of a contemporaneously observed endogenous money supply in rational expectations models of the Lucas-Barro variety. First, if there is contemporaneously perceived policy response (e.g., to interest rates), then a simultaneous equations bias produces inconsistency in the neutrality tests proposed by King and Boschen-Grossman. Second, if money acts as a ‘signal’ about economic conditions then autonomous money shocks can have real effects. In polar contrast to the Lucas-Barro analyses, this non-neutrality requires that monetary information be utilized by economic agents.
