This book organizes entrepreneurship theory in a way that constitutes a new body of knowledge, which is Informational Entrepreneurship. It can serve as a basis for teaching entrepreneurship and reducing performance uncertainty. Although entrepreneurship is not entirely about information, information determines how it can be systematically understood while depending less on luck. It also offers the only known, experimentally tested approach that incorporates decision support tools. Other known approaches rely on exposition for validation; whereas, Informational Entrepreneurship uses two-sample experiments that controlled for other explanations as well as experimenter bias. It will appeal to those studying and teaching entrepreneurship who are looking for a prescriptive approach, rather than a descriptive approach.
