This paper analyzes the welfare effects of term limits for state legislator
s. Legislators tend to pursue their own objectives and deviate from the int
erests of voters as they stay longer in office. However, such long-term inc
umbents become more productive in transferring wealth to their constituents
due to seniority they gain, and voters re-elect the incumbent. Term limits
reduce the maximum seniority of a district's legislator and of other distr
icts' legislators as well, affecting the relative seniority of the legislat
or. Thus, the legislator gains relative seniority sometimes and loses other
times under term limits. As a consequence, voters of a district may or may
not benefit from term limits. The welfare effects of term limits depend cr
ucially on the shape of the voters' utility function.
