In this Paper we estimate the dynamic relationship between resources used in R&D by some OECD countries and their innovation output as measured by patent applications. We first estimate a long-run cointegration relation using recently developed tests and panel estimation techniques. We find that...

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 start-ups and venture capitalists are highly clustered, benefiting from localized spillovers: Silicon Valley is perhaps the best example. There is also substantial geographical variation in venture capital contracts: California contracts are more 'incomplete'. This paper explores the...
