Abstract
The problem of shifts in seasonal behaviour is one which turns up in many time-series, but particularly in the statistics of unemployment. Standard procedures for the seasonal adjustment of economic time-series assume that the amplitude of the seasonal variation either varies in proportion as the level of the series changes (multiplicative seasonality) or is independent of the level (additive seasonality). Economic theory provides little guidance, and some preliminary analysis of the data is usually necessary.
