Standard models of the Bank Lending Channel are unable to yield predictions on the differential impact of monetary policy shocks over heterogeneous borrowers. This inability has made researchers doubt about the role played by bank credit as a transmission mechanism of monetary policy. Moreover,...

We introduce a statistical test for comparing the predictive accuracy of competing copula specifications in multivariate density forecasts, based on the Kullback-Leibler information criterion (KLIC). The test is valid under general conditions on the competing copulas: in particular it allows for...

This paper analyses what determines an individual investor's risk-sharing demand for options and, aggregating across investors, what the equilibrium demand for options. We find that agents trade options to achieve their desired skewness; specifically, we find that portfolio holdings boil down to...

We analyze financial risk premiums and real economic dynamics in a DSGE model with three types of agents--shareholders, bondholders and workers--that differ in participation in the capital market and in attitude towards risk and intertemporal substitution. Aggregate productivity and distribution...

This paper quantifies the effects of two short-run fiscal policies, a temporary tax-cut and rebate transfer, that are intended to stimulate economic activities. A reduction in income taxation provides immediate incentives to work and save more, raising aggregate output and consumption. A...

We quantitatively evaluate a business-cycle environment featuring endogenous capital utilization and nominal price rigidity that illustrates a negative relationship between labor hours and technology (TFP) shocks and a positive relationship between hours and investment (MEI) shocks. Sticky...

This paper investigates the reliability of employing linearization to evaluate the dynamic adjustments to changes in productive government spending in a Ramsey growth model. If government expenditure is introduced as a flow and the dynamic adjustment is fast, linearization may yield a reasonably...

Although it is hard to arrive at a widely accepted definition for Systemic Risk; it is generally acknowledged that it is the risk of the occurrence of an event that threatens the well functioning of the system of interest (financial, payments, banking, etc.) sometimes to the point of making its...

This paper investigates the interactions between stock market fluctuations and monetary policy within a DSGE model for the U.S. economy. First, we design a framework in which fluctuations in households financial wealth are allowed--but not necessarily required--to exert an impact on current...

In this paper a Markov chain Monte Carlo (MCMC) technique is developed for the Bayesian analysis of structural credit risk models with microstructure noises. The technique is based on the general Bayesian approach with posterior computations performed by Gibbs sampling. Simulations from the...
