This study utilizes a flexible Fourier stationary test, proposed by Becker et al. (2006) to investigate the mean reversion of consumption–income ratio in 16 OECD countries from 1960 to 2010. Empirical results from our flexible nonlinear stationary test show that the mean reversion hypothesis...

This study applies a flexible Fourier stationary test, proposed by Becker et al. (2006) to investigate the mean reversion of inflation in 22 OECD countries over the period of 1961 to 2011. While traditional unit root tests give us mixed results, empirical results from our flexible Fourier...
