Complex Unit Roots and Business Cycles: Are They Real?
In this paper the asymptotic properties of ARMA processes with complex-conjugate unit roots in the AR lag polynomial are studied. These processes behave quite di¤erently from regular unit root processes (with a single root equal to 1). In particular, the asymptotic properties of a standardized version of the periodogram for such processes are analyzed, and a nonparametric test of the complex un...
متن کاملFiltering Permanent Cycles with Complex Unit Roots
Separating cyclical movement from trend growth at seasonal and business cycle frequencies is important to macroeconomic research. At business cycle frequencies, time trends, first differences and the more recent Hodrick-Prescott (HP) filter are used to separate trends from cycles. At seasonal frequencies, ad-hoc methods like the Census Bureau’s X-11 seasonal filter are applied. This paper revie...

متن کاملResuscitating Real Business Cycles
The Real Business Cycle (RBC) research program has grown spectacularly over the last decade, as its concepts and methods have diffused into mainstream macroeconomics. Yet, there is increasing skepticism that technology shocks are a major source o f business fluctuations. This chapter exposits the basic RBC model and shows that it requires large technology shocks to produce realistic business cy...
