R&D Spillovers and Global Growth

We examine the growth promoting roles of Ramp;D, international Ramp;D spillovers, and trade in a world econometric model. A country can raise its total factor productivity by investing in Ramp;D. But countries can also boost their productivity by trading with other countries that have large quot;stocks of knowledgequot; from their cumulative Ramp;D activities. We use a special version of MULTIMOD that incorporates Ramp;D spillovers among industrial countries and from industrial countries to developing countries. Our simulations suggest that Ramp;D, Ramp;D spillovers, and trade play important roles in boosting growth in industrial and developing countries
