It is common for a city to use expensive incentives such as a state-of-the-art stadium or tax exemptions to induce a major professional sport team to relocate to or remain in its area.

Their results suggest that major league sports franchises from the four major U.S. team sports (baseball, football, basketball, and hockey) have an adverse impact on local per capita income for U.S. markets in both the short and long run.
