A special issue, Psychological Mechanisms that Affect Economic Decisions to Work Longer, of the online journal, Frontiers in Psychology, Organizational Psychology was recently published, co-edited by Sloan Research Network Members, Gabriela Topa, Joanne Earl, and Jacquelyn James, published in Frontiers in Psychology, section Organizational Psychology. Scholarship on the psychological mechanisms that underlie economic behaviour is crucial to our understanding of how bridge employment opportunities, flexible work options, training for new careers, and starting new businesses might contribute to higher proportions of older workers remaining in the labour market. The expansion of such options is believed to enhance both employer and individual responses to the changing context of aging and work. Thus, the psychological mechanisms that affect economic decisions to work longer was the focus of our special issue. We sought diverse perspectives from around the world illuminating the opportunities and challenges of older workers. The special issue includes 11 papers from 14 countries: Australia, Belgium, Brazil, Chile, China, Ecuador, Germany, Italy, Japan, Netherlands, Portugal, Spain, Switzerland and the United Kingdom. Three themes emerged: Those that potentially inform employment and human resources practises; those that inform career decision making: and those that inform educational practises.
