ABSTRACTThis article analyses the impact of information and consultation regulations specifically the European Information and Consultation Directive on worker participation or employee voice in liberal market economies (LMEs), providing both empirical and theoretical insights to complement existing research on the Directive. Using game theory and the prisoners dilemma framework, and empirical data from 16 case studies, the authors explain why national legislation implementing the Directive is largely ineffective in diffusing mutual gains cooperation in the United Kingdom and Ireland. Three theoretical explanatory propositions advance understanding of the policy impact of information and consultation regulations in LMEs.
