International R&D spillovers, innovation by learning from abroad and medium-run fluctuations

Many developed economies experienced large and correlated fluctuations in the medium run during the postwar period. A good number of industrialized countries experienced high productivity growth during the 1960s and low growth between the early 1970s and the early 1980s. This paper develops a model of medium-run fluctuations incorporating research and development (R&D)-based endogenous growth and international R&D spillovers from a technologically leading country to a technologically lagging country. An important feature of the model is that a key role of the lagging country's R&D is innovation by leaning (IBL) from abroad. After calibration using U.S. and Japanese data, the model shows that changes in U.S.R&D expenditure alone can substantially explain Japan's medium-run fluctuations.The paper argues that the diffusion of U.S. innovations (generated by U.S. R&D) to Japan plays an important role in determining Japan's medium-run fluctuations
