The academic literature suggests that a supermajority tax limitation can be effective in reducing tax burdens and that a tax and expenditure limitation like the Headlee Amendment can do the same. In turn, lower tax burdens seem likely to stimulate economic growth.

These conclusions are based on broad trends in the research literature. While a review of the research is a reasonable basis for evaluating a policy’s effects, it is also reasonable to assess whether Proposal 5’s provisions could have unintended consequences that would vitiate the gains that might otherwise be expected.
