Phillips hypothesis
WebbThe natural rate hypothesis is a key concept in understanding the Phillips curve. This hypothesis suggests that there is a long-run equilibrium level of unemployment, known as the natural rate of unemployment, which is determined by structural factors such as the level of technology, the structure of the labor market, and government policies. http://article.ijarchae.com/pdf/10.11648.j.ija.20240902.11.pdf

Webb2 nov. 2024 · A Dickey-Fuller test is a unit root test that tests the null hypothesis that α=1 in the following model equation. alpha is the coefficient of the first lag on Y. Fundamentally, it has a similar null hypothesis as the unit root test. That is, the coefficient of Y (t-1) is 1, implying the presence of a unit root.
