Abstract: | Public Choice analysis of democratic political institutions focuses on the issues that are most salient under US constitutional arrangements. Parliamentary systems offer different institutional arrangements and different challenges to the Public Choice approach. We outline a Public Choice account of parliamentary democracy which concentrates attention on the roles of electoral competition and disciplined political parties, while also offering a discussion of parliamentary procedure. The Public Choice approach is contrasted with the mainstream view of representative, responsible government in which disciplined political parties are often seen as a threat to parliamentary democracy. |
