No correlation between company-specific tax breaks and a region’s wage and unemployment levels

See Amazon, New York and the End of Corporate Welfare: Special tax breaks do little to spur the economy. Now they’re becoming politically unpopular too by Mene Ukueberuwa of The WSJ

"Since the first boom of company-specific tax breaks in the U.S. during the early 1990s, there has been no correlation between such incentives and a region’s wage and unemployment levels, according to a comprehensive 2017 study by economist Timothy J. Bartik. Luring a big company to town with tax breaks often produces meager results even when the company hires and spends as much as expected, explains the Tax Foundation’s Jared Walczak. “All of these new costs are being subsidized by existing incumbent taxpayers,” he says. Residents and other businesses bear a disproportionate burden of added public costs."
