We introduce a growth model of technology diffusion and endogenous Total Factor Productivity (TFP) levels both at the sector and aggregate level. At the aggregate, the model behaves as the Neoclassical growth model. Our goal is for this model to bridge the gap between the theoretical and...

Even though recent evidence suggests that productivity differences between countries account for the bulk of cross-country differences in per capita income levels and that a large part of these productivity differences are due to countries using different technologies, there is no formal...
