The importance of acquiring and adapting advanced foreign technologies for employment opportunities and economic growth in developing countries can scarcely be overstated. For 10 years the trade research group at the World Bank has undertaken outstanding and innovative empirical studies of the processes under which technology transfer occurs and its impacts on local economies. This volume brings together the fruits of this endeavour and offers a wealth of perspectives and timely information on this central issue for development. It should find a home on the bookshelves of all international development economists and technology specialists.
