This paper considers the effects of refinery outages (due to planned turn-arounds or un-planned events) on current petroleum product prices and future refinery investment. Empirical evidence on these relationships is mixed and highly dependent on the size and duration of the outage, the geographic area considered, the level of inventories available at the time of the outage, and the tightness of the market as measured by the capacity utilization rate. Using a de-tailed database of plant-level refinery outages for both upstream and downstream refining units, I estimate the effects of outages...
