We show that optimal monetary and fiscal policies are time consistent for a class of economies often used in applied work, economies appealing because they are consistent with the growth facts. We establish our results in two steps. We first show that for this class of economies, the Friedman...

Are optimal monetary and fiscal policies time consistent in a monetary economy? Yes, but if and only if under commitment the Friedman rule of setting nominal interest rates to zero is optimal. This result is of applied interest because the Friedman rule is optimal for the standard preferences...

We find conditions for the Friedman rule to be optimal in three standard models of money. These conditions are homotheticity and separability assumptions on preferences similar to those in the public finance literature on optimal uniform commodity taxation. We show that there is no connection...

We study a model with heterogeneous producers that face collateral and cash-in-advance constraints. These two frictions give rise to a nontrivial financial market in a monetary economy. A tightening of the collateral constraint results in a recession generated by a credit crunch. The model can...

We analyse the international transmission of monetary policy shocks with a focus on the effects of foreign liquidity on the euro area. We estimate two domestic structural VAR models for the euro area and then we introduce a global liquidity aggregate. The impulse responses show that a positive...

The paper examines the link between the precision of the available monetary policy indicators and the determinacy of equilibrium in a forward-looking macroeconomic model with partial information and an optimizing central bank. When the information on endogenous variables is not precise enough,...

We develop a new framework to study the implementation of monetary policy through the banking system. Banks finance illiquid loans by issuing deposits. Deposit transfers across banks must be settled using central bank reserves. Transfers are random and therefore create liquidity risk, which in...
