Effects of State Taxation on Investment: Evidence from the Oil Industry

We provide theoretical and empirical evidence that firms do not in general respond equally to changes in prices and taxes in the setting of oil well drilling in the United States. Our key theoretical contribution is that in a multi-state model, a change in output price changes both the benefit and opportunity cost of drilling, whereas a change in a state tax rate only changes the benefit of drilling in that state. Thus, a firm responds more to a change in tax than a change in price. Our econometric results support this theoretical prediction. We find that a one dollar per barrel increase in price leads to a 1 percent increase in wells drilled, but a one dollar per barrel increase in tax leads to at least an 8 percent decrease in wells drilled. These estimates correspond to elasticities of about 0.5 and -0.3, respectively. These results are robust to interstate spillovers, other state regulations, and econometric specification. They imply that using state tax rate decreases to incentivize investment may lead to losses of government revenue.

An estimate of the producer cost of liability for oil spills

ABSTRACT Governments often impose liability for environmental harms on firms when direct monitoring of operations is difficulty or costly. In the case of oil production, little is known about the private cost of liability. This article takes advantage of a natural experiment to estimate the loss in projected future profits of oil and gas production after the Oil Pollution Act of 1990, which imposed liability on some producers and was exogenously timed in response to the Exxon Valdez spill. I find no evidence of economically substantial firm costs of the Oil Pollution Act’s liability rule.
