“…Given these information scarcities, voter behaviour is severely hindered in early elections; among other things, new party systems are characterized by extreme volatility (Bielasiak, 2002;Birch, 2003;Kuenzi and Lambright, 2001;Roberts and Wibbels, 1999), high numbers of parties (Filippov et al, 1999;Golder and Wantchekon, 2004) and frequent electoral law changes. However, while scholars have paid attention to this issue (Bernhard and Karakoç, 2011;Crisp et al, 2012;Lago and Martínez i Coma, 2012;Mishler and Rose, 2007;Raymond et al, 2016;Reich, 2004;Riera, 2013;Selb, 2012;Tavits, 2005;Tavits and Annus, 2006), we do not have a clear understanding of the duration and the causes of these characteristics.…”
