Many developed countries are facing a demographic change with an increasing share of older individuals, yet little is known about how older workers will impact regional and national economies in terms of labor market dynamics. One possible outcome of this new demographic structure is that more individuals will become entrepreneurs at an older age. This Handbook contributes to the important and emerging field of entrepreneurship among this group and focuses on the behavioral perspectives of this phenomenon; on innovation, dynamics and performance; and the ways entrepreneurship among the elderly looks within different countries. Researchers interested in the field of entrepreneurship among older workers and policy makers dealing with the effects of changing demographic settings within countries or regions will turn to this work to gain a better understanding of entrepreneurship and aging.
