In this paper we introduce the cost channel of monetary policy (e.g., Ravenna and Walsh, 2006) into an otherwise standard New Keynesian model of a two-country monetary union, which is being hit by aggregate, asymmetric and idiosyncratic shocks. The single central bank implements the optimal...

This paper presents a general-equilibrium framework to revisit the issues of optimal monetary policies and international policy coordination in a two-country model, focusing on the role of a pricing-to-market (PTM) policy by firms. Both countries may be different with respect to PTM. Using the...

Empirical evidence suggests that the bargaining power of trade unions differs across firms and sectors. Standard models of unionization ignore this pattern by assuming a uniform bargaining strength. In this paper, we incorporate union heterogeneity into a Melitz (2003) type model. Union...

Empirical evidence suggests that high-productivity firms face stronger trade unions than low-productivity firms. Then a policy that puts all unions into a better bargaining position is no longer neutral for firm selection as in models with a uniform bargaining strength across firms. Using a...

In almost all Western economies the median age of the workforce is increasing due to demographic factors. Given the empirical fact that workers of different ages are not perfect substitutes in production, this paper explores how change in the age pattern affects wages and (un)employment. We...

Bei der Kritik an den Rating-Agenturen wird häufig missachtet, dass ihre Macht weitgehend politikgemacht ist. Es sind der Staat und die EZB, die über Gesetze und Regulierungen den Ratings eine Multiplikatorwirkung zuschreiben. Dieser Beitrag skizziert anhand der Länder-ratings die...

There is growing empirical evidence that the strength of the cost channel of monetary policy differs across countries. Using a New Keynesian model of a two-country monetary union, we show how the introduction of a cost channel (differential) alters the optimal monetary responses to union-wide...
