“…For example, when inequality is high, the opportunity costs of activism for poorer (richer) segments of the electorate is substantially lower (higher). However, if the participation rates in partisan activism are much higher among the more affluent sections (with a greater cost elasticity), then this distortion could explain the increased partisanship and political polarization in the U.S. politics (see, e.g., Balart et al, 2018). These observations further suggests that any policy reform that decreases dependence on grassroots activism, like public funding of electoral campaigns, or campaign finance deregulation à la 2010 Citizens United v. FEC ruling, crowds out the demand for activism and increases polarization, in line with the predictions of my theoretical model.…”
