Traditional corporatist groups such as business groups and unions still play an important role in many countries, and the rumors exaggerates the decline of corporatist structures. Nevertheless citizen groups have grown in number and political importance. We show that Danish and Swiss citizen groups have gained better access to the administrative and the parliamentary venues in the period 1975-85 through 2010, but with Swiss citizen groups more successful than their Danish counterparts, particularly with regard to the parliamentary venue. Danish and Swiss neo-corporatism has confronted similar socio-economic and political challenges during this period, but the political opportunity structure is more favourable towards citizen groups in Switzerland than in Denmark. The Swiss referendum institution makes parliamentarians more open to popular demands while in Denmark strong unions, a strong parliament, and frequent minority governments makes it more difficult for citizen groups to be heard.
