Legislative Term Limits

What the evidence says

The claims on this page come from a single study — H. Abbie Erler (2007), published in Public Choice — examined three times with slightly different framings. The consistent finding across all three extractions: states with legislative term limits show higher spending levels than states without term limits. Erler's proposed mechanism is that term limits change legislators' incentive structure, giving them "greater incentives to deviate from socially optimal fiscal policy" once the threat of future elections is removed. Beyond the direction of the spending effect, the evidence here is thin. None of the three claims report an effect size or a measure of statistical significance — one claim states explicitly that "effect size and statistical significance not reported in abstract" and that assessing robustness "would require full paper to assess." No claim here addresses other outcomes commonly discussed alongside term limits — legislative turnover, professionalization, relationships with the executive branch or lobbyists, or effects on legislative productivity — because no source on this page measures them.

Open empirical questions

• What is the magnitude of the spending difference between term-limit and non-term-limit states, and is it statistically significant?
• Does the spending effect hold in panel data with controls for state fixed effects, or is it an artifact of cross-sectional comparison?
• Does an independent study replicate the direction and size of this effect outside the Erler (2007) sample and period?
• What do term limits do to other commonly studied outcomes — legislative turnover, professionalization, executive-legislative balance, lobbyist influence — that no source here measures?
