The paper presents univariate and panel unit root tests for gasoline and oil price convergence over the last decade. We … test for the absolute versus relative version of the law of one price (LOOP) and estimate the speed of convergence as well … as its development over time. Our results show that the absolute version of the LOOP cannot be supported. Constant price …

This paper provides a textbook example of integration between commodity markets, and the subsequent price convergence … or absence thereof. We analyze price relations between spot markets for natural gas in Europe. We apply time …-varying coefficient estimation applying the Kalman filter, to test whether price convergence between different locations is really taking …

We show that there is evidence of pairwise price convergence and that some key … of price-growth convergence, while price-level convergence is not supported by the data. Lastly, we assess the the short …-run implications of price convergence focusing on the speed of reversion to equilibrium after a system-wide shocks hits the …
