This research investigates the convergence of local consumer price indexes (CPIs) within Japan using a pairwise … the period 1975–2011. The hypothesis of no convergence is rejected regarding the general and disaggregated CPIs, but … shares of converging pairs in all possible pairs are often limited. There is differing extent of convergence among goods and …

We consider how unit root and stationarity tests can be used to study the convergence properties of prices and rates of … initial conditions, the case of primary interest for analysing convergence. We argue that the joint use of unit root and … series that have already converged, and we set out a strategy to establish whether convergence occurs in relative prices or …
