The creation, success and long-term survival of enterprises are fundamentally linked to the effectiveness of decision-making processes and negotiation capabilities. This book provides an overview of research into how decisions permeate entrepreneurial ventures throughout their lifecycle. A multidisciplinary approach combining psychology, sociology and political science is used to investigate how entrepreneurs address and deal with decision-making. The respective contributions highlight the latest empirical, theoretical and meta-research, and bridge the gap between literature on entrepreneurship, entrepreneurial and innovative behaviours with that on decision-making and negotiation. This book is one of the first to combine these streams of research, thereby offering a new and insightful addition to the field of entrepreneurship.
