Is it one break or ongoing permanent shocks that explains U.S. real GDP?

Journal of Monetary Economics, 2014, 66, pp155-163.

    我院罗穗老师在宏观经济学一流期刊Journal of Monetary Economics上发表论文(Journal of Monetary Economics, 66, 155-163)。下面是论文的摘要 。 
    The relative importance of permanent versus cyclical shocks to GDP has been found to depend on the presence or absence of a single break in mean growth. We estimate unobserved components models conditional on a trend break having occurred in any specified quarter and use the Bayesian model averaging to combine the conditional estimates. We estimate a break occurred around 2006:1. Allowing for a break significantly reduces estimates of trend variance. However, enough spread remains in the posterior distribution to indicate that available data does not definitively settle the question of the relative importance of trend versus cycle.
