Perla and Tonetti (2014) and Lucas and Moll (2014) study technology diffusion in isolation, in environments without the generation of new ideas. Without new ideas, growth cannot continue forever if there is a finite technology frontier. This paper examines, in an economy in which firms choose to...

Will fast growing emerging economies sustain rapid growth rates until they “catch-up” to the technology frontier? Are there incentives for some developed countries to free-ride off of innovators and optimally “fall-back” relative to the frontier? This paper models agents growing as a...

We study how endogenous innovation and technology diffusion interact to determine the shape of the productivity distribution and generate aggregate growth. We model firms that choose to innovate, adopt technology, or produce with their existing technology. Costly adoption creates a spread...
