In this paper we investigate purchasing power parity (PPP) in a panel with 17 countries for the period 1972 through 1996. The novel feature of our panel methodology is that results are invariant to the choice of a benchmark on numeraire currency. In the panel we allow individual country effects in the relation between prices and exchange rates. In this way we can identify the currency pairs for which PPP holds or does not hold. We conclude that there is substantive evidence for PPP, although not to the same extent for every currency. Evidence in favor of PPP is strongest for many exchange rates relative to the Dmark, and weakest for the Japanese yen. For this currency a trend-like variable, like productivity growth, is missing.
