How should monetary policy respond to a commodity price shock in a resource-rich economy? We study optimal monetary policy in a simple model of an oil exporting economy to provide a first answer to this question. The central bank faces a trade-off between the stabilization of domestic inflation...

This paper takes a first step in analysing how a monetary union performs in the presence of labour market asymmetries. Differences in wage flexibility, market power and country sizes are allowed for in a setting with both country-specific and aggregate shocks. The implications of asymmetries for...

The optimal currency literature has stressed the importance of labor mobility as a precondition for the success of monetary unions. But only a few studies formally link labor mobility to macroeconomic adjustment and policy. In this paper, we study macroeconomic dynamics and optimal monetary...

In this paper we study the transmission mechanism of productivity shocks in a model with rule-of-thumb consumers. In the literature, this financial friction has been studied only with reference to fiscal shocks. We show that the presence of rule-of-thumb consumers is also very helpful in...

In this paper we show that empirically plausible results on the effects of fiscal shocks in Galí, López-Salido and Vallés (2007) rely on a high degree of price stickiness and a large percentage of financially constrained agents. Real rigidities in the form of habit persistence, fixed...

Current business cycle models systematically underestimate the correlation between consumption and investment. One reason for this failure is that a positive investment-specific technology shock generally induces a negative consumption response. The objective of this paper is to investigate...

In this paper we study the transmission for capital depreciation shocks. The existing literature in the Real Business Cycle tradition has concluded that these shocks are irrelevant for business cycle fluctuations. We show that these shocks are potentially important drivers of aggregate...

Recent studies find that shocks to the marginal efficiency of investment are a main driver of business cycles. Yet, they struggle to explain why consumption co-moves with real variables such as investment and output, which is a typical feature of an empirically recognizable business cycle. In...
