Abstract
It is sometimes assumed that the R(2) of a regression of a first-order differenced time series on seasonal dummy variables reflects the amou nt of seasonal fluctuations that can be explained by deterministic var iation in the series. In this paper we show that neglecting the presen ce of seasonal unit roots may yield spuriously high values of this coe fficient.
