The Handbook of Entrepreneurial Dynamics provides an important forum for scholars to generate new theory, identify promising research directions, and present important insights to a very wide audience of scholars in entrepreneurship. The book is formed by empirical research from the Panel Study of Entrepreneurial Dynamics (PSED), and is the first attempt to develop a comprehensive and thoroughly representative portrait of entrepreneurial activity in the United States that can be applied to other countries. In order to study individuals as their businesses and organizations take shape, this study located and studied nascent entrepreneurs while in the process of building their enterprises.
