We analyze the stability of efficiency rankings of German universal banks between 1993 and 2004. First, we estimate traditional efficiency scores with stochastic cost and alternative profit frontier analysis. Then, we explicitly allow for different risk preferences and measure efficiency with a...

The impact of uncertainty on firms? investment outlays is subject to an ongoing debate. Theory identifies several channels. Irreversibility, financing constraints and risk aversion make a negative relationship between uncertainty and investment likely. On the other hand, the ability of firms to...

This paper tests some of the predictions of recent advances in trade theory that have focused on different trade patterns of firms within the same sector. Helpman, Melitz and Yeaple (2005) develop a model in which innate productivity differences between firms determine the degree of...

Following a positive shock, financing constraints will prolong or impede economic expansion that would have been optimal in an unconstrained environment. The study of dynamic adjustment therefore offers a direct way of verifying the presence of financing constraints and assessing their...

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...

We analyse stylised facts for Germany's business cycle at the firm level. Based on longitudinal firm-level data from the Bundesbank's balance sheet statistics covering, on average, 55,000 firms per year from 1971 to 1998, we estimate transition probabilities of a firm in a certain real sales...

We establish some stylised facts for Germany's business cycle at the level of the firm. Based on longitudinal firm-level data from the Bundesbank's balance sheet statistic covering, on average, 55,000 firms per year from 1971 to 1998, we analyse the reallocation across individual producers and,...

Aggregated output in industrialized countries has become less volatile over the past decades. Whether this ?Great Moderation? can be found in firm level data as well remains disputed. We study the evolution of firm level output volatility using a balanced panel dataset on German firms that...

Recent macro developments in the euro area have highlighted the interactions between fiscal policy, sovereign debt, and financial fragility. We take a structural macroeconomic model with frictions in the financial intermediation process, in line with recent research, but introduce asset choice...
