In this paper we study the transmission for capital depreciation shocks. The existing literature in the Real Business Cycle tradition has concluded that these shocks are irrelevant for business cycle fluctuations. We show that these shocks are potentially important drivers of aggregate...

Recent studies find that shocks to the marginal efficiency of investment are a main driver of business cycles. Yet, they struggle to explain why consumption co-moves with real variables such as investment and output, which is a typical feature of an empirically recognizable business cycle. In...

We estimate demand, supply, monetary, investment and financial shocks in a VAR identified with a minimum set of sign restrictions on US data. We find that financial shocks are major drivers of fluctuations in output, stock prices and investment but have a limited effect on inflation. In a second...

Current business cycle models systematically underestimate the correlation between consumption and investment. One reason for this failure is that a positive investment-specific technology shock generally induces a negative consumption response. The objective of this paper is to investigate...

We investigate the macroeconomic consequences of .uctuations in the effectiveness of the labor-market matching process with a focus on the Great Recession. We conduct our analysis in the context of an estimated medium-scale DSGE model with sticky prices and equilibrium search unemployment that...

A large decline in the e¢ ciency of the U.S. labor market in matching unemployed workers and vacant jobs has been documented during the Great Recession. We use a simple New Keynesian model with search and matching frictions in the labor market to study the propagation of matching e¢ ciency...

We propose a new VAR identfication scheme that enables us to disentangle labor supply shocks from wage bargaining shocks. Identification is achieved by imposing robust signrestrictions that are derived from a New Keynesian model with endogenous labor force participation. According to our...

In this paper we study the impact of an expansion in public spending in a credit constrained economy with sticky wages. The flexible wage version of the model implies strong expansionary effects on output and consumption but also a counterfactual increase in real wages. The introduction of...

In this paper we study the transmission mechanisms of productivity shocks in a model with rule-of-thumb consumers. In the literature, this financial friction has been studied only with reference to fiscal shocks. We show that the presence of rule-of-thumb consumers is also very helpful in...

This paper attempts to measure the reaction of monetary policy to the stock market. We apply the procedure of Rigobon and Sack (2003) to identify and estimate a VAR in the presence of heteroskedasticity. This procedure fully takes into account the endogeneity of interest rates and stock returns...
