- Abstract
- We use mixed-frequency (quarterly-monthly) data to estimate a dynamic stochastic general equilibrium model embedded with the financial accelerator mechanism à la Bernanke et al. (1999). We find that the financial accelerator can work very differently at monthly frequency compared to the quarterly frequency, i.e. we document its inversion. That is because aggregating monthly data into quarterly leads to large biases in the estimated quarterly parameters and, as a consequence, to a deep change in the transmission of shocks.

- Abstract
- Two approaches are considered to incorporate judgment in DSGE models. First, Bayesian estimation indirectly imposes judgment via priors on model parameters, which are then mapped into a judgmental interest rate decision. Standard priors are shown to be associated with highly unrealistic judgmental decisions. Second, judgmental interest rate decisions are directly provided by the decision maker, and incorporated into a formal statistical decision rule using frequentist procedures. When the observed interest rates are interpreted as judgmental decisions, they are found to be consistent with DSGE models for long stretches of time, but excessively tight in the 1980s and late 1990s and excessively loose in the late 1970s and early 2000s.

- Abstract
- In this paper I estimate a New Keynesian Dynamic Stochastic General Equilibrium model for the Euro Area, which closely follows the structure of the model developed by Smets and Wouters (2003, 2005, 2007), with the addition of the so-called financial accelerator mechanism developed in Bernanke, Gertler and Gilchrist (1999). The main aim is to obtain a time series for the unobserved external finance premium that entrepreneurs pay on their loans, with the further aim of providing a dynamic analysis of it. Results confirm in general what was recently found for the US by De Graeve (2008), namely that (1) the model incorporating financial frictions can generate a series for the premium, without using any financial macroeconomic aggregates, that is highly correlated with available proxies for it, (2) the estimated premium is not necessarily counter-cyclical (this depends on the shock considered). Nevertheless, although in addition the model with financial frictions better describes Euro Area data than the model without them, the former is not satisfactory in many other respects. For instance, the accelerator effect turns out to be statistically not significant. However, this does not impede financial frictions from remaining a key ingredient to model. In fact, I found that the estimated premium is a very powerful predictor of inflation. It overcomes, in terms of the Mean Squared Forecast Error, the traditional output gap measure in a Phillips curve specification.
