Informal Institutions and Democracy

Informal institutions have grown in relevance for the analysis of new 'third wave' democracies. The research strategy receives its impetus from the debate on neo‐institutionalism theory, which offers a productive perspective for structuring the field of analysis. This article explains the distinguishing factors between formal and informal institutions. It addresses five basic types of informal institutions, examines the ways in which they function and discusses their relevance in terms of democracy theory. Each type is characterized by the way in which it enacts its respective means of political influence. The study distinguishes between forms of specific relationship (clientelism), of material exchange (corruption), of violent exertion of influence (putsch threat), of civil resistance (civil disobedience) and of legal practice (custom law), and discusses their relevance to democracy. The central argument maintains that a differentiated study of informal institutions is crucial to addressing this question. The necessary typological differentiation allows us to make an appropriate assessment ‐one that does not manifest itself in a simple clear‐cut choice of affirmative or negative answers.
