| Abstract: | Abstract: The rate of turnover within parliaments remains an understudied area of research. The present paper contributes to filling this gap by presenting the first comparable macro‐level data on legislative turnover in the 26 Swiss cantonal legislatures. In examining the strikingly different levels of turnover in sub‐national Swiss parliaments between 1993 and 2011, the focus is on politico‐institutional features. Multilevel models reveal that two hitherto neglected institutional variables are correlated with legislative turnover. In addition to the reduction of parliamentary size, we find the strength of a cantonal parliament to affect turnover rates on the Swiss sub‐national level. Moreover, we show that proportional representation significantly promotes parliamentary elite circulation. Among the non‐institutional covariates, we find that electoral volatility is also relevant in explaining legislative turnover rates. |
