Replication Data for: The Effect of District Magnitude on Electoral Outcomes: Evidence from Two Natural Experiments in Argentina

This paper addresses this question by exploiting a combination of two natural experiments in Argentina between 1985 and 2015. Argentine provinces elect half of their congressional delegation every two years, and thus districts with an odd number of representatives have varying magnitudes in different election years. Furthermore, whether a province elects more representatives in midterm or concurrent years was decided by lottery in 1983. The results indicate that district magnitude (a) increases electoral support for small parties, (b) increases the (effective) number of parties getting seats, and (c) reduces electoral dis- proportionality. The last two results are driven by the mechanical rather than the psychological effect of electoral rules' .
