We develop a microeconomic model of endogenous growth where clean and dirty technologies compete in production and innovation—in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to...

This paper argues that openness to new, unconventional and disruptive ideas has a first-order impact on creative innovations-innovations that break new ground in terms of knowledge creation. After presenting a motivating model focusing on the choice between incremental and radical innovation,...

We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A key feature is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using detailed US...

We build a micro-founded model with endogenous firm innovation and growth. This enables us to examine the forces jointly driving innovation, productivity and reallocation. We estimate this using simulated methods of moments on detailed US Census micro data on output, R&D and patenting, obtaining...

We develop a microeconomic model of endogenous growth where clean and dirty technologies complete in production and innovation - in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to...
