We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

This paper studies the introduction of new products (increase in product variety) in the automobile industry. The focus is on the two sources of market power that may allow the firms to get higher profits (and, thus, recoup investments): new products and brand-name reputation. The effects of new...

In this study, we present novel statistics on the patenting in US manufacturing and new evidence on the question of what happens when firms patent. We do so by creating a comprehensive firm-patent matched dataset that links the NBER patent data (covering the universe of patents) to firm data...

We analyze the effect of a labor market reform on firms' product innovation. The re- form, which amounts to a natural experiment, differentially reduced firing costs for some firms, thereby lowering adjustment costs in the presence of demand uncertainty. Using a difference-in- differences...

This paper analyzes the impact of technological diversity on innovation inputs and success using Swiss firm-level panel data. While we do not find any impact of diversity on R&D intensity, we confirm a positive impact of diversity on patent applications as suggested by the literature. However,...
