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...

This paper investigates how competition and firm size affect the relationship between market uncertainty and R&D investment. We use an intuitively appealing measure of firm-specific uncertainty along with panel data to show that firms invest less in current R&D as uncertainty about market...

Does regulation affect the pace and nature of innovation and if so, by how much? We build a tractable and quantifiable endogenous growth model with size-contingent regulations. We apply this to population administrative firm panel data from France, where many labor regulations apply to firms...

This paper investigates how competition and firm size affect the relationship between market uncertainty and R&D investment. We use an intuitively appealing measure of firm-specific uncertainty along with panel data to show that firms invest less in current R&D as uncertainty about market...

This paper analyses determinants of firm R&D and if predictions from the model of creative destruction is supported by data using matched employer-employee longitudinal data on the Swedish manufacturing industry. In particular, we analyse the impact of competition on R&D. Using various measures...

A rich literature links knowledge inputs with innovative outputs. However, most of what is known is restricted to manufacturing. This paper analyzes whether the three aspects involving innovative activity - R&D; innovative output; and productivity - hold for knowledge intensive services....
