Additive versus multiplicative seasonal adjustment when there are fast changes in the trend-cycle: CS11-614/85-50E-PDF

"This article analyses some aspects of the interplay between a severe recession and seasonal adjustment. In just one year, that is in 1981, this recession has nearly doubled the level of beneficiaries. Such a sudden large change prompts questions about the structure of the series, the choice of the X-11-ARIMA decomposition model, the determination of turning points at the end of the series, and the use of ARIMA forecasts for seasonal adjustment"--Introduction, p. [1].
