Relaxing these restrictions can close the gap between DSGE models and vector autoregressions. This paper modi¯es a simple stochastic growth model by incorporating permanent labor supply shocks that can generate a unit root in hours worked. Using Bayesian methods we estimate two versions of the DSGE model: the standard speci¯cation in which hours worked are stationary and the modi¯ed version with permanent labor supply shocks. We ¯nd that the data support the latter speci¯cation.  \nJEL CLASSIFICATION: C32, E52, F41  \nKEY WORDS: Bayesian Econometrics, DSGE Models, Non-stationary Hours  \n¤ Yongsung Chang: School of Economics, Shillim-Dong, Kwanak-Gu, Seoul, Korea 151-742; email: [Yohg@snu.ac.kr](Yohg@snu.ac.kr).

Since these models generate both business cycle °uctuations as well as long-run growth paths, they should ultimately be able to match data across all frequencies. Despite the signi¯cant progress in developing empirically viable models, e.g., Christiano, Eichenbaum, and Evans (2005) and Smets and Wouters (2003), the time series ¯t of DSGE models is typically inferior to the ¯t of vector autoregressions (VAR) that are estimated with well-calibrated shrinkage methods, as documented in Del Negro, Schorfheide, Smets, and Wouters (2004) . One reason for the poor time series ¯t is the restrictions imposed by the so-called balanced growth path. Along the balanced growth path, (i) the \\big ratios\" (investment-output, consumption-output, capital-output, and real wage-output) are stable as output, consumption, investment, capital stock, and real wages grow at the same rate, and (ii) the real rates of return to capital and per capita hours worked are stationary.1 As pointed out, for instance, by Canova, Finn, and Pagan (1994), these model-implied co-trending relationships are often rejected by the data. Modi¯cations to the probabilistic structure of the exogenous shocks that generate °uctuationsin DSGE models can be used to generalize trend structures. For instance, in a two-sector model Edge, Laubach, and Williams (2003) introduce trends in sector-speci¯c productivity processes such that the relative price of investment becomes non-stationary and real investment and consumption can grow at di®erent ","cbCaiuJ0auGEz4VH","https://ap.wps.com/l/cbCaiuJ0auGEz4VH","pdf",798530,"English","# Abstract\n## 1 Introduction","[{\"question\":\"What problem do DSGE models face in matching data over the long run?\",\"answer\":\"Their time series often suffer from long-run dynamic restrictions that are inconsistent with the data.\"},{\"question\":\"How does the paper modify the DSGE framework to address hours worked dynamics?\",\"answer\":\"It incorporates permanent labor supply shocks into a stochastic growth model so that hours worked can generate a unit root.\"},{\"question\":\"What do the Bayesian estimates conclude about the preferred specification?\",\"answer\":\"The data support the modified specification with permanent labor supply shocks rather than the standard stationary-hours model.\"}]","WORKING PAPER NO. 06-3 - NON-STATIONARY HOURS IN A DSGE MODEL - Abstract | PDF",1789742018,48]
