Abstract
The paper examines the processes underlying economic fluctuations by investigating the volatility moderation of US economy in the early 1980s We decompose the volatility decline using a dynamic factor framework into a common stochastic trend common transitory component and idiosyncratic components We find that the moderation of business cycle was a result of the moderation in transitory and idiosyncratic components Our results suggest that important part of stochastic process that drives economy is transitory The paper investigates the role of oil prices monetary and financial market factors Proposed economic factors do not have a significant relationship to either transitory or permanent components In addition we find that transitory shocks are as common during the 1980s and 1990s as they were during the 1960s and 1970sWe would like to thank Bruce Mizrach Sung Won Kang and seminar participants at the 2004 Summer Meetings of Econometric Society Rutgers University and UNCC for helpful feedback Special thanks are to the editor of the journal for helpful comments and to an anonymous referee for proposing an alternative econometric model
