摘要
US data show that the external finance premium, measured by the high yield bond spread, moves countercyclically and leads movements in output by four quarters. This paper constructs a model with nominal rigidities and financial accelerator to explain this observation. The key finding of this paper is: it is agents' reaction on news about future technology changes that generates the observed countercyclical movement and lead-lag pattern of the external finance premium, while a contemporary technology shock generates a procyclical movement of the external finance premium. The variance decomposition based on the estimated model demonstrates that news shocks account for about 72% of fluctuations in the external finance premium.
