Phillips hypothesis
WebbIn statistics, the Phillips–Perron test (named after Peter C. B. Phillips and Pierre Perron) is a unit root test. [1] That is, it is used in time series analysis to test the null hypothesis that a time series is integrated of order 1. It builds on the Dickey–Fuller test of the null hypothesis in , where is the first difference operator. Webbtween this hypothesis and the more orthodox view that the rate of inflation is an argument in the wage-change equation with a co-effl-cient less than unity. It does draw attention to the importance of executing a test which will discriminate between these hypotheses, which have very different policy implications under certain welfare functions.
