I consider a Vickrey-Salop model of spatial product differentiation with quasi-linear utility functions and contrast two modes of production, the proprietary model where entrepreneurs sell software to the users, and the open source model where users participate in software development. I show...

Recent empirical studies suggest a need for a flexible patent regime responding to industry characteristics. In practice, sector-specific modifications of patent strength already exist but lack theoretical foundation. This paper intends to make up for this neglect by scrutinizing in what...

This paper examines how Korea's import and export linkages with China affect the innovation outcomes of Korean manufacturing firms. Using our automated algorithm, we match Korean patent data to KIS-Value firm data from 1996 to 2015. We find that rising import and export with China lead to more...

This paper analyses the impact of common ownership on markups and innovation and adds to the discussion of the recently observed patterns of a long term rise in market power. We shed light on the inconclusiveness of results regarding the effects of common ownership on markups in the existing...

In the ICT sector, product-software is an important factor for the quality of the products (e.g. cell phones). In this context, open source software enables firms to avoid quality competition as they can cooperate on quality without an explicit contract. The economics of open source (OS) versus...

We introduce international mobility of knowledge workers into a model of Nash equilibrium IPR policy choice among countries. We show that governments have incentives to use IPRs in a bidding war for global talent, resulting in Nash equilibrium IPRs that can be too high, rather than too low, from...

This paper introduces competitive markets in the Grossman-Helpman [1991, ch. 3] increasing variety growth model. In this standard model of endogenous growth theory, competition has a negative incentive effect. Accordingly, a larger resource base is required to sustain long run growth. In an...

This article analyzes how the perceived effectiveness of intellectual property protection and competitive pressure affect firms' innovation strategy choices, concretely, whether to abstain from innovation, to introduce products that are known in the market but new to the firm (imitation) or to...

Can U.S. patent law help American businesses compete in global markets? In early 2011, President Barack Obama argued that, to obtain economic prosperity, the United States must “out-innovate . . . the rest of the world,” and that patent reform is a “critical dimension[]” of this...
