Other times, states have found the programs aren't doing what they were supposed to, Goodman said.
"Incentives are often part of this competition between states for jobs and investment," Goodman said. "But on the other hand, incentives come with a cost and a lot of states, including Illinois, are still dealing with significant budget problems, so that's why it's so important for states to really do rigorous analysis to make sure the dollars they commit to incentives are dollars well spent."
