We analyze the relationship between firm-specific shocks and aggregate fluctuations. In particular, profitability of firms affected by a negative shock worsens. To the extent that the banks cannot distinguish between aggregate and firm-specific profitability shocks, they will adjust interest...

Did the increase in counterparty risk perception in the interbank market since autumn 2007 contribute to the severe contraction of the US economy? To address this question we introduce interbank market uncertainty in a DSGE model with frictional financial intermediation. Interbank uncertainty is...

The topic of this paper is the estimation uncertainty of the Stock-Watson and Gonzalo-Granger permanent-transitory decompositions in the framework of the co-integrated vector autoregression. We suggest an approach to construct the confidence interval of the transitory component estimate in a...

We analyze the theoretical moments of a nonlinear approximation to real business cycle model with stochastic volatility and recursive preferences. We nd that the conditional heteroskedasticity of stochastic volatility operationalizes a time-varying risk adjustment channel that induces...

We show that TFP reacts counter-cyclically to macroeconomic shocks, which we identify by imposing sign restrictions. Counterfactual simulations, based on a New Keynesian DSGE model, show that firms manage to employ labor more efficiently during downturns, which leads to a muted drop in the...

This paper presents a dynamic stochastic general equilibrium model which studies the business-cycle implications of financial frictions and liquidity risk at the bank-level. Following Holmstr m and Tirole (1998), demand for liquidity reserves arises from the anticipation of idiosyncratic...
