“…A growing body of work has proposed that the existence and strength of PBCs may depend on a range of conditioning or mediating variables (for reviews and empirical evidence, see de Haan & Klomp, 2013 and Klomp & de Haan, 2013). These include the level of democracy or electoral competitiveness (Block, 2002; Eibl & Lynge‐Mangueira, 2017; Gonzalez, 2002; Vergne, 2009), electoral rules and government types (Chang, 2008; Persson & Tabellini, 2003), democratic experience (Brender & Drazen, 2005); the quality of governance and the share of informed voters in the electorate (Alt & Rose, 2009; Janků & Libich, 2019; Shi & Svensson, 2006; Veiga et al, 2017; Vergne, 2009); fiscal transparency and political polarization (Alt & Lassen, 2006), checks and balances (Alt & Rose, 2009; Chang, 2008; Garmann, 2018; Streb et al, 2009; Streb & Torrens, 2013), and party age (Hanusch & Keefer, 2014). Taken together, this body of work has found that PBCs are stronger in the presence of greater electoral competition, proportional electoral rules and presidential systems, less experience with democracy, poorer quality of governance, fewer informed voters, less fiscal transparency, greater political polarization, fewer checks and balances, and younger political parties.…”
