Gesell taxes on money holdings have received attention in recent decades as a way of alleviating the zero lower bound on interest rates. Less known is that such a tax was the predominant method used to generate seigniorage in large parts of medieval Europe for around two centuries. When the...

We develop a theory of innovation for entry and sale into oligopoly, and show that inventions of higher quality are more likely to be sold (or licensed) to an incumbent due to strategic product market effects on the sales price. Such preemptive acquisitions by incumbents are shown to stimulate...

External financing is important when inventors and small technology-based firms wish to commercialize their inventions. However, it is likely that problems related to adverse selection and moral hazard are present, and market failures occur, since inventors know more about the inventions than do...

According to Schumpeter, the creative process of economic development can be divided into three distinguishable stages of invention, innovation (commercialization) and imitation. We show why there is a rationale for the Schumpeterian entrepreneur to also include the inventor in the innovation...

Using a unique database on individual Swedish patents, a survival model estimates how different factors influence the time it takes until commercialization starts. To the best of my knowledge, such an analysis has not been undertaken before. For external financing of patent projects and small...

In this paper, I analyze the commercialization of patents in the Swedish medicine & hygiene sector. A unique database makes it possible to use a new method, where I follow the commercialization process of individual patents. A surprisingly low share (10%) of the inventions was discovered at...

Globalization, high growth rates in high-tech industries, growing emerging markets and harmonization of patent institutions across countries have stimulated patenting in foreign markets. We use a simple model of international patenting, where the decision to patent in a foreign country depends...

One of the major reasons why inventors are awarded patents by governments is they encourage R&D investments and commercialization of inventions. If the patent holder commercializes his invention, he has stronger incentives to retain the patent. The purpose here is to empirically analyze the...

I apply a survival model to a detailed dataset of Swedish patents to estimate how different factors affect the likelihood of patent renewal. Since the owners know more about the patents than potential external financiers, there is a problem of asymmetric information. To overcome this, Sweden has...
