This article explores whether comparative institutionalism can be used to identify path-dependent approaches to the management of ageing workforces in the United Kingdom (UK) and Hong Kong Special Administrative Region (HKSAR), and considers whether and how the global phenomenon of population ageing is leading to a convergence of approaches between Western and Eastern economies. Using semi-structured expert interviews, the article discusses these countries' approaches to employment regulation, welfare provision and public sector employment. The findings show that the two economies exhibit a converging trend: namely shifting responsibilities for extended longevity from the state and employer towards the individual worker. However, stakeholder pressure (especially from trade unions) has tempered this trend in the UK more than in HKSAR. This indicates that stakeholders' relative ability to use their agency in setting and pursuing agendas that diverge from public policy paths influences not only national-level policymaking but also organisational-level HRM.
