We explore the use of patent citations to measure the "basicness" and appropriability of inventions. We propose that the basicness of research underlying an invention can be characterized by the nature of the previous patents cited by an invention; that the basicness of research outcomes relates...

This paper surveys the major changes in patent policy and practice that have occurred in the last two decades in the U.S., and reviews the existing analyses by economists that attempt to measure the impacts these changes have had on the processes of technological change. It also reviews the...

We estimate the impact of participating in the NZ Marsden Fund on research output trajectories, by comparing the subsequent performance of funded researchers to those who submitted proposals but were not funded. We control for selection bias using the evaluations of the proposals generated by...

The challenge of mitigating climate change has focused recent attention on basic scientific research feeding into the development of new energy technologies (Popp, 2017). Energy innovation tends to consist of a series of partially overlapping processes involving: (1) the production of scientific...
