Abstract (EN)

This paper analyses the e¤ects of money shocks on macroeconomic aggregates within a flexible price, incomplete markets environment that generates persistent wealth inequalities amongst agents. In this framework, unexpected money shocks redistribute wealth from the cash-rich employed to the cash-poor unemployed and induce the former to increase labour supply in order to maintain their desired levels of consumption and precautionary savings. The reduced-form dynamics of the model is a textbook output-inflation tradeoff equation, whereby inflation shocks raise current output. The limiting impact of mean inflation and money growth persistence on this non neutrality mechanism are also examined.
