To model the observed slow response of aggregate real variables to nominal shocks, most macroeconomic models incorporate real rigidities in addition to nominal rigidities. One popular way of modelling such a real rigidity is to assume a non-constant demand elasticity. By using a homescan data...

Optimal monetary policy depends crucially on whether agents have exogenous, endogenous-inelastic, or endogenous-elastic attention. We show in this paper that, under elastic attention, optimal monetary policy may induce equilibria that are not possible under the other two settings: decision...
