Exit of venture-backed firms often takes place through sales to large incumbent firms. We show that in such an environment, venture-backed firms have a stronger incentive to develop basic innovations into commercialized innovations than incumbent firms, due to strategic product market effects....

We document the presence of multiple and varied constraints to small and medium firm growth. This presents both a practical problem for business training programs and a challenge to academic economists trying to identify mechanisms though which these programs may affect outcomes. External...

We analyze incentives to develop entrepreneurial ideas for venture capitalists (VCs) and incumbent firms. If VCs are sufficiently better at judging an idea's value and if it is sufficiently more costly to patent low than high value ideas, VCs acquire valuable ideas, develop them beyond the level...

Innovative ideas are novel combinations of productive resources potentially addressing an economic need (Schumpeter, 1926). Even promising ideas can be unprofitable if the proposed combination fails on at least one dimension, e.g., it is technically unfeasible or does not respond to a genuine...

We review the role of R&D in endogenous growth theory, and describe extant empirical research – macro and micro – bearing on R&D as an engine of growth. Taking R&D to be key, while recognizing the significance of economic incentives, emphasizes knowledge as an economic object and, more...

The intellectual breakthrough contributed by the new growth theory was the recognition that investments in knowledge and human capital endogenously generate economic growth through the spillover of knowledge. Endogenous growth theory does not explain how or why spillovers occur. The missing link...
