Technology and Bilateral Trade
We develop a Ricardian model to explore the role of trade in spreading the benefits of" innovation. The theory delivers an equation for bilateral trade that gravity specification, but identifies underlying parameters of technology. We estimate the" equation using trade in manufactures among the OECD. The parameter estimates allow us to" simulate the model to investigate the role of trade in spreading the benefits of innovation and to" examine the effects of lower trade barriers. Typically foreigners benefit by only a tenth as much" as the innovating country, but in some cases the benefits to close neighbors approach those of the" innovator.
