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...

We study the variability of business growth rates in the U.S. private sector from 1976 onwards. To carry out our study, we exploit the recently developed Longitudinal Business Database (LBD), which contains annual observations on employment and payroll for all U.S. businesses. Our central...

We develop a model of an industry with many heterogeneous firms that face both financing constraints and irreversibility constraints. The financing constraint implies that firms cannot borrow unless the debt is secured by collateral; the irreversibility constraint that they can only sell their...

Les défaillances sont en forte hausse depuis l’été 2008 et tendent à concerner en 2009 des entreprises de taille plus significative.

The number of business failures has risen sharply since summer 2008. In 2009, these failures tended to be observed among larger companies.

The theory of transformation pressure maintains that central actors in established firms will be more productive when experiencing an actual fall in profits. Actors fearing that the survival of the firm is at stake will then become more alert, calculating and creative favoring a transformation....

First Draft: November 1, 2011 We propose a theory of endogenous firm-level volatility over the business cycle based on endogenous market exposure. Firms that reach a larger number of markets diversify market-specific demand risk at a cost. The model is driven only by total factor productivity...

Recessions are conventionally considered as times when the least productive rms are driven out of the market. Do credit frictions hamper this cleansing eect of recessions? We build and calibrate a model of rm dynamics with endogenous exit and credit frictions to investigate this question. We nd...

Are nominal prices sticky because menu costs prevent sellers from continuously adjusting their prices to keep up with inflation or because search frictions make sellers indifferent to any real price over some non-degenerate interval? The paper answers the question by developing and calibrating a...

In this paper I evaluate the contribution of financial frictions in explaining the drop in aggregate TFP through misallocation during the Great Recession. I build a quantitative model with heterogeneous establishments; with the help of the model I compute the counterfactual drop in...
