We construct a political economy model of …scal federalism with state …scal asymmetries that originate in heterogeneity in natural resource abundance, representing a non-mobile source of income that provides a …scal advantage in the inter-state …scal competition. The model shows that representatives of natural resource rich states are more willing to vote in favor of federal tax increases, despite the lower net …scal bene…fits their states receive.

Our results indicate that the …scal advantage channel is as dominant as party affiliation in driving legislators' ’voting decisions over federal tax policies.
