This paper exhibits and quantifies a new theoretical channel of the non-neutrality of inflation transiting through capital market imperfections. Unconstrained households change their financial position in front of a change in the inflation rate, whereas constrained households can not. Thus...

The joint behaviour of US aggregate consumption and saving over the period 2007--2009, and notably the pronouned U-shaped pattern of consumption together with the rise in saving, are difficult to reconcile with the view that financial markets are frictionless.

This paper analyzes the long-run effect of monetary policy when credit constraints are taken into account. This analysis is carried on in a heterogeneous agents framework in which infinitely lived agents can partially self-insure against income risks by using both financial assets and real...

This paper analyses the effects of money shocks on macroeconomic aggregates in 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...
