Malapportionment in Space and Time: Decompose It!
Yuta Kamahara, Junichiro Wada, Yuko Kasuya
Electoral Studies 71 102301 2021.6 [Reviewed]
DOI Web of Science CiNii Research
Language：English Publishing type：Research paper (scientific journal) Publisher：ELSEVIER Joint Work
Existing studies on legislative malapportionment often conceptualize and measure this phenomenon with little regard to intertemporal variations and the malapportionment-generating process (MGP). Our conceptualization leads us to introduce a measure called alpha-divergence that can identify the vote inequality derived from various stages of MGP. Using an originally created database that covers 440 elections in 112 countries, we decompose the overall degree of malapportionment into three stages: malapportionment that arises at the stages of interstate apportionment, intrastate districting, and allotment of seats to special districts. We also provide analyses that can decompose the demographic and political factors contributing to the trends of the overall degree of malapportionment for selected countries.
