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 LOOP and estimate the speed of convergence as well as its development over time. Our results show that the absolute version...

We empirically analyze convergence of European producer and consumer prices for diesel fuel and investigate the role of excise taxation. By comparing the speed of convergence of prices and taxes we find a surprisingly fast speed of convergence for consumer prices. While this can in part be...
