As a consequence, the estimation of actual business cycles relies on relatively simple filters that remove from the series the long-term trend. Over the last decade there has been a convergence towards the use of a filter suggested by Hodrick and Prescott (HP). The present paradigm, in actual practice, is to estimate the cycle with the HP filter applied to X11-seasonally adjusted series. The procedure has been the subject of academic criticism that has pointed out the risk of obtaining spurious cycles, mostly associated with the empirical and fixed nature of the filter. The filter also is known to present some serious drawbacks such as unstable estimation for recent years so that concurrent...
