The ageing of populations worldwide has implications for workforces in developed countries and labour shortages have increasingly become a political concern. Governments in developed countries have responded by increasing the retirement age as a strategy for overcoming the fall in labour supply. Using bibliometric techniques, we reviewed 122 articles published between 1990 and 2018 to examine the effectiveness of the strategy in addressing the labour shortages and, in particular, to identify the factors that contribute positively to maintaining worker participation within an ageing workforce at an organizational level. The results identified five organizational factors that support continued participation: health, institutions, human resource management (HRM), human capital and technology tools. Employers will increasingly need to develop "age-friendly" workplaces and practices if they are to recruit and retain older workers.
