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...

Collecting information on prices is a costly endeavor. The cost depends on the relative ease with which those prices can be collected, and in many retail gasoline markets, there is a substantial divide in the ease of collecting information with regular grade gasoline on one side of the divide...

Despite a large number of studies that examine the influence of biofuels and biofuel policy on commodity prices, the impact of biofuel policy on commodity price variability is poorly understood. A good understanding of biofuel policy's impact on price variability is important for mitigating food...
