The global demographic shift toward an aging population is reshaping labor markets, social policies, and economic structures at an unprecedented pace. Across many countries, longer life expectancy and declining birth rates are increasing the proportion of older adults in the workforce, making age diversity a defining feature of modern economies. As the proportion of older workers increases, economies face both challenges and opportunities in sustaining productivity, ensuring fiscal stability, and promoting social inclusion. Traditional labor market models, designed for younger populations, are no longer sufficient to address the needs of today's diverse workforce. At the same time, advances in technology, lifelong learning initiatives, and innovative workplace practices are offering new pathways for harnessing the potential of older employees. The Economics of an Aging Workforce: Challenges, Opportunities, and Policy Perspectives explores the multifaceted economic dimensions of an aging workforce, bringing together contributions from scholars, policymakers, and practitioners across disciplines. By integrating empirical evidence and theoretical perspectives, this book illuminates how societies can adapt to demographic change while ensuring sustainable growth and intergenerational equity. Covering topics such as green transitions, late-life entrepreneurship, and lifelong learning, this book is an excellent academic resource for graduate and doctoral students, business leaders, economists, HR professionals, policymakers, and more.
