“…This article tests the effects of FPTP in the Mongolian elections of 2016 by analysing national- and district-level results. Especially, we address the question whether the electoral competition at district level was consistent with Duverger’s law (two-party competition) and resulted in restoration of bipolar party politics, which were disrupted in 2012 due to the use of MMM together with the previous split of the post-communists, or whether some elements of multiparty competition that resulted from the outcomes of the 2012 elections due to contamination across the components of the mixed system (so-called contamination thesis, see Herron and Nishikawa, 2001; Rich et al, 2014), also prevailed at the district level in 2016. Due to the frequent electoral engineering, Mongolia could serve as a very useful case for testing hypotheses related to Duverger’s law in the context of a transforming party system, especially as a large part of the literature on electoral systems is based on research in Western Europe and other older democracies, with limited insight into institutional reforms in younger democracies (Rich et al, 2014: 649).…”
