Does medical technology originating in countries close to the technology frontier have a significant impact on health outcomes in countries distant from this frontier? This paper considers a framework where lagging countries may benefit from medical technology (a result of research and development by countries close to the frontier) that is embodied in medical imports or diffuses in the form of ideas. Using a novel dataset from a cross-section of 73 technology-importing countries, we show that medical technology diffusion is an important contributor to improved health status, as measured by life expectancy and mortality rates.
