Revisiting the uncertain unit root in GDP and CPI: Testing for non-linear trend reversion
AbstractWe test for the presence of a unit root in U.S. GDP and CPI, allowing for non-linear trend reversion under the alternative hypothesis. In contrast to most previous results, we find evidence in favour of trend stationarity for both variables.
