Abstract: Taiwan's retail and farm prices were examined for unit roots at various seasonal frequencies. The results show that no unit roots exist at any seasonal frequency. Additionally, a unit root exists at the zero frequency in marketing margins, reflecting that retail and farm prices are not co-integrated at the long-run frequency.
