In this paper we consider why firms sometimes choose an external development path for their own inventions, despite the costs of contracting and the risks of opportunistic behaviour and expropriation. We model the probability that firms adopt an external development strategy using survey data...

We use data from 3000 academic scientists to estimate the effects of other parties’ patents on the academics’ research. Nearly half of all scientists report that their choice of research projects has been affected by the presence of other parties’ patents. We find that transaction costs...

Patents may assist trade in technology either by protecting buyers against the expropriation of the idea by third parties (the appropriation effect) or by enabling sellers to more frankly disclose the idea during the negotiation phase (the disclosure effect). We test for the presence of both...

Conditional on the decision to enter the market for immature technology, we test for the effects that trust – as proxied by the context in which the negotiating parties met – has on the likelihood that these negotiations are successful. Using a randomised dataset of 860 university-firm and...

A low-quality patent system threatens to slow the pace of technological progress. Concerns about low patent quality are supported by estimates from litigation studies suggesting that the majority of patents granted by the U.S. patent office should not have been issued. This paper proposes a new...

One of the great unknowns of patent policy is how much infringement goes on, and how much of that infringement leads to enforcement of an informal or formal kind. Our representative survey of over 3700 Australian inventors estimates that 28 per cent of inventions (which were the subject of a...
