"The Evolution of Scientific Knowledge" aims to reach a unique understanding of science with the help of economic and sociological theories. The economic theories used are institutionalist and evolutionary. The sociological theories draw from the type of work on social studies of science that has, in recent decades, transformed our picture of science and technology. Science - and more broadly research - is a field where economics and sociology meet in an attempt to understand how complex organizations emerge and work. While the authors argue that science is neither an institution nor an order that emerged as the result of conscious and wilful design, nor is it like a "normal" market, they also acknowledge that science has aspects of market orders and aspects of orders created by design. Furthermore, science develops in specific ways that are to some extent like the development of economic systems, and at the same time are very different.
