An analytical framework predicts that, in response to an exogenous increase in resource-based government revenue, a benevolent government will partially substitute away from taxing income, increase spending and save. Fifty-one years of US-state level data are largely consistent with this theory. A baseline fixed effects model predicts that a $1.00 increase in resource revenue results in a $0.25 decrease in nonresource revenue, a $0.43 increase in spending and a $0.32 increase in savings. Instrumenting for resource revenue reveals that a positive revenue shock is largely saved and the rest is transferred back to residents in the form of lower nonresource tax rates.
