Harhoff, Dietmar; Stoll, Sebastian - 2015

One of the objectives of patent systems is to disclose information which other agents can build on in further inventions and in their decision-making. While some observers take it as given that real-world patent systems serve this objective, we argue in this article that patent systems are...

What do deficits tell us about debt? : empirical evidence on creative accounting with fiscal rules in the EU

Hagen, Jürgen von; Wolff, Guntram B. - 2006

Fiscal rules, such as the Excessive Deficit Procedure and the Stability and Growth Pact (SGP), aim at constraining government behavior. Milesi-Ferretti (2003) develops a model in which governments circumvent such rules by reverting to creative accounting. The amount of this depends on the...

Incidence and growth of patent thickets : the impact of technological opportunities and complexity

Graevenitz, Georg von; Wagner, Stefan; Harhoff, Dietmar - 2011

We investigate incidence and evolution of patent thickets. Our empirical analysis is based on a theoretical model of patenting in complex and discrete technologies. The model captures how competition for patent portfolios and complementarity of patents affect patenting incentives. We show that...
