What are the connections between science and improvements in economic and social outcomes that drive the “value” of science? Most of the time, these connections are circuitous, varied, diffuse, and opaque. Patent data offer an opportunity to expose new connections between science and...

Patent citations are one of the most commonly-used metrics in the innovation literature. Leading uses of patent-to-patent citations are associated with the quantification of inventions’ quality and the measurement of knowledge flows. Due to their widespread availability, scholars have...

We review the econometric literature on measuring the returns to R&D. The theoretical frameworks that have been used are outlined, followed by an extensive discussion of measurement and econometric issues that arise when estimating the models. We then provide a series of tables summarizing the...
