America is in the midst of a sports construction boom. New sports facilities costing at least $200 million each have been completed or are under way in Baltimore, Charlotte, Chicago, Cincinnati, Cleveland, Milwaukee, Nashville, San Francisco, St. Louis, Seattle, Tampa, and Washington, D.C., and are in the planning stages in Boston, Dallas, Minneapolis, New York, and Pittsburgh. Major stadium renovations have been undertaken in Jacksonville and Oakland. Industry experts estimate that more than $7 billion will be spent on new facilities for professional sports teams before 2006. Most of this $7 billion will come from public sources. The subsidy starts with the federal government, which allows state and local governments to issue tax-exempt bonds to help finance sports facilities. Tax exemption lowers interest on debt and so reduces the amount that cities and teams must pay for a stadium. Since 1975, the interest rate reduction has varied between 2.4 and 4.5 percentage points. Assuming a differential of 3 percentage points, the discounted present value loss in federal taxes for a $225 million stadium is about $70 million, or more than $2 million a year over a useful life of 30 years. Ten facilities built in the 1970s and 1980s, including the Superdome in New Orleans, the Silverdome in Pontiac, the now-obsolete Kingdome in Seattle, and Giants Stadium in the New Jersey Meadowlands, each cause an annual federal tax loss exceeding $1 million. State and local governments pay even larger subsidies than Washington. Sports facilities now typically cost the host city more than $10 million a year. Perhaps the most successful new baseball stadium, Oriole Park at Camden Yards, costs Maryland residents $14 million a year. Renovations aren't cheap either: the net cost to local government for refurbishing the Oakland Coliseum for the Raiders was about $70 million. Most large cities are willing to spend big to attract or keep a major league franchise. B...
