We characterize optimal monetary policy in a New Keynesian search-and-matching model where multiple-worker firms satisfy demand in the short run by adjusting hours per worker. Imperfect product market competition and search frictions reduce steady state hours per worker below the efficient...

Business 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. We find a positive and...

This paper presents new evidence on the formation of producer prices based on a onetime survey that was conducted on a sample of 1200 German firms in manufacturing in June 2004. Most of the firms have price-setting power and apply mark-up pricing. Indexation is negligible. Fixed nominal...

This paper presents new evidence on the formation of producer prices. The database combines a one-time survey that was conducted in June 2004 on a sample of 1,200 firms in manufacturing and time-series information on price adjustment of the same firms from a business-tendency survey. The share...

Is time-varying firm-level uncertainty a major cause or amplifier of the business cycle? This paper investigates this question in the context of a heterogeneousfirm RBC model with persistent firm-level productivity shocks and lumpy capital adjustment, where cyclical changes in uncertainty...

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

This paper analyses the role of bank-related constraints in explaining the sharp slowdown in bank lending to non-financial corporations in Germany during the recent financial crisis. We use a panel approach based on a unique data set which matches the individual responses of the banks...

In this paper we 'update' the option implied probability of default (option iPoD) approach recently suggested in the literature. First, a numerically more stable objective function for the estimation of the risk neutral density is derived whose integrals can be solved analytically. Second, it is...

We use a Diamond/Dybvig-based model with two banks operating in separate regions connected by a common asset market in which banks and sophisticated depositors invest. We study the effect of a potential run (crisis) and subsequent fire sales on the asset price in both the crisis and no-crisis...

Bond excess returns can be predicted by macro factors, however, large parts remain still unexplained. We apply a novel term structure model to decompose bond excess returns into expected excess returns (risk premia) and the unexpected part. In order to explore these risk premia and innovations,...
