This paper studies optimal monetary policy with the nominal interest rate as the single policy instrument in an economy,where firms set prices in a staggered way without indexation and real money balances contribute separately to households'utility. The optimal deterministic steady state under...

What is the role of contracting schemes for the welfare costs of nominal rigidities over the business cycle? We examine 4 different modeling schemes of nominal rigidities that all have the same average duration of contracts. We find that Calvo (1983) wage and price contracts may deliver welfare...

This paper examines how money demand induced real balance effects contribute to the determination of the price level, as suggested by Patinkin (1949,1965), and if they affect conditions for local equilibrium uniqueness and stability. There exists a unique price level sequence that is consistent...

In this paper we propose a novel methodology to analyze optimal policies under model uncertainty in micro-founded macroeconomic models. As an application we assess the relevant sources of uncertainty for the optimal conduct of monetary policy within (parameter uncertainty) and across models...

We develop a novel argument why better public information can help countries to insure against idiosyncratic risk. Representative agents of developing and industrial countries receive public and private signals on their future income realization and engage in risk-sharing contracts with limited...

This paper investigates whether assuming that households possess advance information on their income shocks helps to overcome the difficulty of standard models to understand consumption insurance in the US. As our main result, we find that the quantitative relevance of advance information...
