This paper analyzes the quality of VAR-based procedures for estimating the response of the economy to a shock. We focus on two key issues. First, do VAR-based confidence intervals accurately reflect the actual degree of sampling uncertainty associated with impulse response functions? Second,...

We provide empirical evidence that a positive shock to technology drives up per capita hours worked, consumption, investment, average productivity and output . This evidence contrasts sharply with the results reported in a large and growing literature that argues, on the basis of aggregate data,...

We show that the standard procedure for estimating long-run identified vector autoregressions uses a particular estimator of the zero-frequency spectral density matrix of the data. We develop alternatives to the standard procedure and evaluate the properties of these alternative procedures using...

We investigate what happens to hours worked after a positive shock to technology, using the aggregate technology series computed in Basu, Fernald, and Kimball (1999). We conclude that hours worked rise after such a shock. (JEL: E24, E32, O3) Copyright (c) 2004 The European Economic Association.
