In this paper we investigate the effects of uncertainty shocks on economic activity using a Dynamic Stochastic General Equilibrium (DSGE) model with heterogenous agents and a stylized banking sector. We show that frictions in credit supply amplify the effects of uncertainty shocks on economic...

We introduce costly firm-entry a la Bilbiie et al. (2012) into a New Keynesian model with Epstein-Zin preferences and show that it can jointly account for a high mean value of bond and equity premium without compromising the fit of the model to first and second moments of key macroeconomic...

The benefit from using second-order approximations tostochastic dynamic rational expec- tations models is explained. By example of the neoclassical growth model, this note as- sesses the accuracy of the obtained approximation. The implications for optimal policy are discussed.
