“The book is potentially a timely and welcome contribution that goes against the stream in the flood of books on innovation but also on why countries remain poor. It contributes with an evolutionary perspective on the largely ignored phenomenon of technological retrogression, which, in turn, might be a major cause behind continuous falling behind and persistent poverty levels. The message to the development debate is clear – poor countries need to diversify and get their manufacturing sectors going.” —Martin Andersson, Associate Professor, Lund University, Sweden
