Borders and Distance in Knowledge Spillovers : Dying over Time or Dying with Age? - Evidence from Patent Citations
Li, Yao Amber - 2012
This paper uses a gravity framework to investigate the effects of distance as well as subnational and national borders in knowledge spillovers. Drawing on the NBER Patent Citations Database, we examine patent citations data at metropolitan level within the U.S. and the 38 largest patent-cited...

Gambling to Leapfrog in Status?
Friehe, Tim - 2013
This paper shows that households with positional concerns and convex status utility use gambling to attempt leapfrogging in the social hierarchy. We test this theoretical prediction relying on household data that is representative for Germany, proxying the status orientation of households by...

Cumulative Innovation, Growth and Welfare-Improving Patent Policy
Chor, Davin - 2013
We construct a tractable general equilibrium model of cumulative innovation and growth, in which new ideas strictly improve upon frontier technologies, and productivity improvements are drawn in a stochastic manner. The presence of positive knowledge spillovers implies that the decentralized...

A Model of Patent Trolls
Choi, Jay Pil - 2015
This paper develops a model of patent trolls to understand various litigation strategies employed by nonpracticing entities (NPE). We show that when a NPE faces multiple potential infringers who use related technologies, it can gain a credible threat to litigate even when it has no such...

An Economic Model of Patent Exhaustion
Ivus, Olena - 2020

Population Aging and Inventive Activity
Irmen, Andreas - 2016
This research empirically establishes and theoretically motivates the hypothesis that population aging has a hump-shaped effect on inventive activity. We estimate this hump-shaped relationship in a panel of 33 OECD countries over the period 1960-2012. The increasing part of the hump captures the...
