For Which Countries did PPP hold ? A Multiple Testing

We use recent advances in the multiple testing literature to identify those countries for which Purchasing Power Parity (PPP) held over the last century. The approach controls the multiplicity problem inherent in simultaneously testing for PPP on several time series, thereby avoiding spurious rejections. It has higher power than traditional multiple testing techniques by exploiting the dependen...
