This article argues that after the Golden Age of capitalism, corporatist methods of policy-making have come to depend on specific modes of party competition. In contrast to previous studies of corporatism, which have argued that corporatism depends on strong social democratic parties, this article suggests that the competition between well-defined left-wing and right-wing ‘blocs’ has become detrimental to corporatism. In countries with mixed governments or traditions of power-sharing, on the other hand, corporatism thrives. These conclusions are based on a comparison of four traditionally corporatist countries – Denmark, the Netherlands, Sweden and Switzerland – from the early 1970s to the late 1990s.
