This book explores how and why the transposition of EU directives in the new and contentious policy area 'Business and Human Rights' differs between member states. It reveals the extent to which individual member states are pursuing diverging approaches in dealing with the 'discretionary space' in EU directives, and highlights theoretical and political explanations. Drawing on historical institutionalism and rational choice institutionalism, the book establishes a link between the degree of corporatism in a given political economy and government behaviour in terms of Business and Human Rights policy. Moreover, it identifies political salience within the policy subsystem as a pertinent factor for explaining national transposition outcomes.
