--- - |2 Abstract Why are some policies protested more than others? New data on protest against eight categories of taxation in twenty rich democracies from 1980 to 2010 reveal that economically and socially concentrated taxes are protested most, whereas taxes that confer entitlement to benefits are protested least. Other features of policy design often thought to affect the salience or visibility of costs are unimportant for explaining the frequency of protest. These findings overturn a folk theory that political sociology has inherited from classical political economy; clarify the conditions under which policy threats provoke protest; and shed light on how welfare states persist. - 'The British Journal of Sociology, Volume 69, Issue 3, Page 647-669, September 2018.
