The destruction of New Haven’s commercial and manufacturing economy was no accident. It was a result of the growth of Yale and other tax-exempt institutions on what had been a flourishing free-enterprise economy.
In 1950, 27 percent of New Haven real estate — the chief source of municipal revenues — was exempted from taxation. A decade later, this had risen to 43 percent. By 1990, 65 percent of New Haven’s real estate was tax exempt, meaning the owners of the remaining 35 percent of taxable property had to make up the difference through steep increases in taxes.
