This paper proposes a new procedure for detecting the presence of periodically collapsing rational bubbles via an analysis of the properties of the relevant observable time series. The procedure is based on random-coefficient autoregressive models. An empirical application of the procedure to German hyperinflation data is examined and discussed. (C) 2001 Elsevier Science B.V.
