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

This paper examines whether the existence and the timing of real balance effects contribute to the determination of the absolute price level, as suggested byPatinkin (1949,1965), and if they affect conditions for local equilibrium uniqueness and stability. I show that there exists a unique price...

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...

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...

During the turbulent 1970s and 1980s the Bundesbank established an outstandingreputation in the world of central banking. Germany achieved a high degree of domesticstability and provided safe haven for investors in times of turmoil in the internationalfinancial system. Eventually the Bundesbank...

Size effects matter in banking. Typically, banking systems are dominated by a smallnumber of large players who are also active in a large range of countries and marketsegments. At the same time, there exist small and often regionally-focused financialinstitutions. This holds also for the German...

Using the Consensus Economics dataset with individual expertforecasts from G7 countries we investigate determinants of disagreement (crosssectionaldispersion of forecasts) about six key economic indicators. Disagreementabout real variables (GDP, consumption, investment and unemployment)has a...

Existing menu cost models, when parameterized to match the micro-price data, cannot reproduce the extent to which the fraction of price changes increases with inflation. In addition, in the presence of strategic complementarities, they predict implausibly large menu costs and misallocation. We...

We develop a tractable sticky price model in which the fraction of price changes evolves endogenously over time and, consistent with the evidence, increases with inflation. Because we assume that firms sell multiple products and choose how many, but not which, prices to adjust in any given...

This paper uses a Bayesian estimation approach to examine the behavior of the Sierra Leone’s economy by creating a small-open economy DSGE model that includes financial frictions. The study utilises a New Keynesian framework to examine the actions of diverse economic agents, such as...
