In other words, the Yankees received a federal subsidy to build their stadium. How much? About $431 million. That’s a lot of money, but it gets worse.
The loss in federal tax revenues was even higher than the subsidy to the stadium. High-income taxpayers holding the bonds receive a windfall tax break, resulting in an even greater loss of revenue to the federal government. In the case of Yankee Stadium, the additional loss was $61 million. That is, the federal government subsidized the construction of Yankee Stadium to the tune of $431 million federal taxpayer dollars, and high-income bond holders received an additional $61 million.†
