Busniess cycle models with sticky prices and endegenous firm entry make novel predictions on the transmission of shocks through the extensive margin of investment. This paper tests some of these predictions using a vector autoregression with model-based sign restrictions. [...]

Using a unique German firm-level data set, this paper is the first to jointlystudy the cyclical properties of the cross-sections of firm-level real value addedand Solow residual innovations, as well as capital and employment adjustment.We find two new business cycle facts: 1) The cross-sectional...

Is time-varying firm-level uncertainty a major cause or amplifier of the businesscycle? This paper investigates this question in the context of a heterogeneousfirmRBC model with persistent firm-level productivity shocks and lumpy capitaladjustment, where cyclical changes in uncertainty...

Strong procyclical fluctuations in the durable production are the most prominent featureof the empirical response to monetary shocks. This paper investigates the role of preferencesin matching this feature of the data in a two-sector sticky price model with flexibly priceddurables. The reaction...

While consumption habits have been utilised as a means of generating a hump shapedoutput response to monetary policy shocks in sticky-price New Keynesian economies,there is relatively little analysis of the impact of habits (particularly, external habits) onoptimal policy. In this paper we...

This paper analyzes empirically the impact of fiscal policy on the price level for the cases of Germany and Spain. We investigate whether the fiscal theory of the price level (FTPL) is able to deliver a reasonable explanation for the different performances of the price level in these two...

This paper explores the macroeconomic consequences of preferences displaying asubsistence point. It departs from the existing related literature by assuming thatsubsistence points are specific to each variety of goods rather than to the compositeconsumption good. We show that this simple feature...

The unfolding financial turmoil in mature economies has prompted the official and private sectors to reconsider policies, business models and risk management practices. Regardless of its future evolution, it already threatens to become one of the defining economic moments of the 21st century....

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...
