摘要：
This paper proposes new quantile unit root tests for panel data with common shocks, whose critical values can be simulated based on our asymptotic theory. The Monte Carlo simulation results indicate that our tests perform well in finite sample. An application for real effective exchange rates (REERs) suggests that the Purchasing Power Parity (PPP) hypothesis holds for higher quantiles but does not hold for lower ones, and the asymmetric dynamics of REERs provide a plausible explanation for the PPP puzzle.(c) 2022 Elsevier B.V.
