Using the approach suggested by Gabaix (Econometrica 2011) this paper demonstrates that idiosyncratic shocks in the largest firms are important for an understanding of aggregate volatility in German manufacturing industries. The implications of this finding for theoretical and empirical research...

Government interventions into the financial system in the form of bail out operations or liquidity assistance are often justified with the systemic importance of large banks for the real economy. In this paper, we test whether idiosyncratic shocks to loan growth at large banks have effects on...

Standard GMM estimates of the New Phillips curve on euro-area data yield degrees of nominal rigidity that are not in accordance with recent microeconomic evidence. This paper studies whether similar conclusions are reached in a richer model where price setters face firm-specific capital and/or...

Using Bayesian likelihood methods, this paper estimates a dynamic stochastic general equilibrium model with Taylor contracts and firm-specific factors in the goods market on euro-area data. The paper shows how the introduction of firmspecific factors improves the empirical fit of the model and...

The common assumptions that labor income share does not change over time or across countries and that factor income shares are equal to the elasticity of output with respect to factors have had important implications for economic theory. However, there are various theoretical reasons why the...

Critics of foreign aid programs have long argued that poverty reflects government failure. In this paper I analyze the effectiveness of foreign aid programs to gain insights into political regimes in aid recipient countries. My analytical framework shows how three stylized political/economic...
