Book excerpt: The notion and interpretation of path dependence have been discussed and utilized in various social sciences during the last two decades. This innovative book provides significant new insights onto how the different applications of path dependence have developed and evolved. The authors suggest that there has been a definite evolution from applications of path dependence in the history of technology towards other fields of social science. They also discuss the various definitions of path dependence (strong or weak) and explore the potential applications of path dependence in new areas such as political economy and economic geography. With new perspectives on how the debate surrounding path dependence has evolved, this book will strongly appeal to postgraduate students and scholars of economic history, economic geography, political science and business studies.
