In models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. In this paper, we develop a two-sector two-good closed economy new Keynesian model to study the optimal choice of price index in markets with...

In this paper, I analyze the pros and cons of implementing structural reforms of the labor market in booms vs. recessions, in light of considerations of social efficiency, political viability, and macroeconomic fine tuning. While the optimal timing of a reform depends on the relative importance...

This paper deals with potential instabilities in the Eurozone stemming from an insufficient interplay between monetary policy and reform effort on the one hand and the emergence of intra-Euro area divergences on the other. As a first step, we assess the effect of EMU on structural reform and...

We test the significance of the relationship between the exchange rate regime and the degree of structural reforms by estimating panel regressions for a world and an OECD country sample. The empirical results suggest a positive correlation between on the one side the adoption of an exchange rate...

This paper examines the contemporaneous relationship between the exchange rate regime and structural economic reforms for a sample of CEEC/CIS transition countries. We investigate empirically whether structural reforms are complements or substitutes for monetary commitment in the attempt to...

In this paper, we propose a search and matching model with nominal stickiness à la Calvo in the wage bargaining. We analyze the properties of the model, first, in the context of a typical real business cycle model driven by stochastic productivity shocks and second, in a fully specified...

We consider a model with frictional unemployment and staggered wage bargaining where hours worked are negotiated every period. The workers' bargaining power in the hours negotiation affects both unemployment volatility and inflation persistence. The closer to zero this parameter, (i) the more...

In this paper we incorporate a labor market with matching frictions and wage rigidities into the New Keynesian business cycle model. In particular, we analyze the effect of a monetary policy shock and investigate how labor market frictions affect the transmission process of monetary policy. The...

This paper provides a new explanation of why inflation is sluggish in response to aggregate demand shocks and why aggregate output changes as result of such shocks. We argue that these phenomena are related to lags between inputs and outputs in the production process, "production lags" for...

Bei Vorliegen nach unten starrer Nominallöhne erschwert niedrige Inflation Reallohnanpassungen und führt so möglicherweise zu erhöhter gleichgewichtiger Arbeitslosigkeit. Dieser Aufsatz analysiert die wachsende Evidenz zu nach unten starren Nominallöhnen. Es werden nicht nur die...
