In this book, fifteen prominent scholars of the economy, business, and technology argue that technical change can fruitfully be interpreted as an institutionally structured learning process. These essays show that the analysis of knowledge-generating institutions - including firms, industries, patenting systems, and occupations - provides important insights into the pace, direction, and persistence of technological change. The authors use these insights to both reshape economic theory and reinterpret the economic development of Britain, the USA, Germany and Japan.
