Many studies have shown that small firms generate more patents per R&D dollar than large firms. Does this mean that small firms are more efficient innovators than large firms? In this paper we exploit a unique data set to reexamine the firm size-innovation relationship. Because firm-reported R&D...

Patents are monopolies granted to inventors in order to promote innovation, but they have a limited term because they also impose social costs. There is little empirical research on what constitutes an optimal patent term, or whether patent term should vary across industry categories. We take a...

Using new data on citations to university patents and scientific publications, we study how geography affects university knowledge spillovers. Citations to patents decline sharply with distance and are strongly constrained by state borders. The effect of distance on citations to scientific...

La capacidad de competir globalmente ha sido algo cambiante en el tiempo. Los procesos de innovación tecnológica y la educación condicionan en gran medida el crecimiento económico y esa competitividad internacional. La evolución y desarrollo histórico de los derechos de propiedad...

Two court decisions in the 1990s are widely viewed as having opened the door to a flood of business method and financial patents at the US Patent and Trademark Office, and to have also impacted other patent offices around the world. A number of scholars, both legal and economic, have critiqued...

The patent system makes organized markets in patents with transparent prices possible. Such prices are here investigated as "signals" for inventors and innovators alike of valuable "technology areas," in an experimental study. They inform decisions of specialized "firms" on allocation of...

The question of how prices on patents rights should be determined in impersonal exchanges is examined in a laboratory environment. Dynamic gains from such organized trade with public prices are recorded. The experiment introduces a competitive market with impersonal exchange mechanisms and...

We are well familiar with the economic analysis of a patent system in terms of a temporary monopoly on products, benefitting from marginal process inventions, formulated under conditions of certain future demands. This article develops an experimental and dynamic microeconomic model useful for...
