Ake E.Andersson has always been intellectually on the move. He has selected his own track through the academic system and has formed a school of thought which has brought him international recognition. The cornerstones of his scie¤ntific interest are welfare analysis, regional economic dynamics and human capital theory. For his excellent achievements on dynamic analysis in the field of regional economics and regional planning he received the Japanese Honda Prize in 1995. This book provides a sample of the broad ranging research of Ake E.Andersson. Here some of his friends and colleagues have contributed to give various examples from the growing research field ""Knowledge and Networks¤ in a Dynamic Economy"" in which he has been a great inspiration and in which he has contributed as part of his prodigious output.
