This paper seeks to present two Dynamic Stochastic General Equilibrium models – Curdia e Woodford (2009) e De Graeve (2007) – that allows identify mechanisms in which financial frictions can influence business cycles and domestic monetary policies. We extend the basic traditional New Keynesian model that considers the role of financial intermediation in the credit markets. Models in which a credit spreads is introduced allows for a time-varying wedge between the interest rate available to households on their savings and the interest rate at which it is possible to borrow These spreads are not constant over time, especially in periods of financial stress. Variations in the financial conditions, indicated by increases ou decreases in the size of credit spreads, implies consequences both for the equilibrium relation between the policy rate and aggregate expenditure and for the relation between real activity and inflation.
