November 2018Measuring the Impact of Household Innovation using Administrative Data
with Javier Miranda: w25259
We link USPTO patent data to U.S. Census Bureau administrative records on individuals and firms. The combined dataset provides us with a directory of patenting household inventors as well as a time-series directory of self-employed businesses tied to household innovations. We describe the characteristics of household inventors by race, age, gender and U.S. origin, as well as the types of patented innovations pursued by these inventors. Business data allows us to highlight how patents shape the early life-cycle dynamics of nonemployer businesses. We find household innovators are disproportionately U.S. born, white and their age distribution has thicker tails relative to business innovators. Data shows there is a deficit of female and black inventors. Household inventors tend to work in cons...
September 2018An Anatomy of U.S. Firms Seeking Trademark Registration
with Emin M. Dinlersoz, Nathan Goldschlag, Amanda Myers: w25038
This paper reports on the construction of a new dataset that combines data on trademark applications and registrations from the U.S. Patent and Trademark Office with data on firms from the U.S. Census Bureau. The resulting dataset allows tracking of various activity related to trademark use and protection over the life-cycle of firms, such as the first application for a trademark registration, the first use of a trademark, and the renewal, assignment, and cancellation of trademark registrations. Facts about firm-level trademark activity are documented, including the incidence and timing of trademark registration filings over the firm life-cycle and the connection between firm characteristics and trademark applications. We also explore the relation of trademark application filing to firm em...
An Anatomy of U.S. Firms Seeking Trademark Registration
with Emin Dinlersoz, Nathan Goldschlag, Amanda Myers
in Measuring and Accounting for Innovation in the 21st Century, Carol Corrado, Jonathan Haskel, Javier Miranda, and Daniel Sichel, organizers
This paper reports on the construction of a new dataset that combines data on trademark applications and registrations from the U.S. Patent and Trademark Office with data on firms from the U.S. Census Bureau. The resulting dataset allows tracking of various activity related to trademark use and protection over the life-cycle of firms. Facts about firm-level trademark activity are documented, including the incidence and timing of trademark registration filings over the firm life-cycle and the connection between firm characteristics and trademark applications. The analysis indicates that trademark filing is correlated with employment and revenue growth. There appears to be strong selection into trademark filing for trademark registration based on firm size and age. Firms seeking trademark r...
January 2017Proximity and Economic Activity: An Analysis of Vendor‐University Transactions
with Nathan Goldschlag, Julia Lane, Bruce Weinberg: w23018
This paper using transaction based data to provide new insights into the link between the geographic proximity of businesses and associated economic activity. It contributes to the literature by developing both two new measures of distance and a set of stylized facts on the distances between observed transactions between vendors and customers for a research intensive sector – universities. We show that spending on research inputs is more likely to be expended at businesses physically closer to universities than those farther away. That relationship is stronger for High Tech and R&D performing businesses than businesses in general, which is consistent with theories emphasizing the role of tacit knowledge. We find that firms behave in a way that is consistent with the notion that propinqui...
