I apply a survival model to a detailed data set 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...

The purpose of this study is to present a unique database on commercialized patents and to illustrate how it can be used to analyze the commercialization process of patents. The dataset is based on a survey of Swedish patents owned by inventors and small firms with a remarkably high response...

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...

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...

The aim of this paper is to provide new empirical evidence on the most crucial determinants of success for firms applying for public R&D grants. Previous studies have been limited to firm level data and mainly tested how firm characteristics affect the allocation of R&D grants. Thereby, they...

In medieval Europe, old coins were frequently declared invalid and exchanged for new ones at fixed rates and dates. Here, the question of whether and when such re-coinage was applied in medieval Sweden is analyzed against the historical record. A theory of how short-lived coinage systems work is...

Although the leaf-thin bracteates are the most fragile coins in monetary history, they were the main coin type for almost two centuries in large parts of medieval Europe. The usefulness of the bracteates can be linked to the contemporary monetary taxation policy. Medieval coins were frequently...

Re-coinage implies that old coins are declared invalid and exchanged for new ones at fixed exchange rates and dates. Empirical evidence shows that re-coinage could occur as often as twice a year within a currency area in the Middle Ages. The exchange fee at re-coinage worked as a monetary tax...

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...

I apply a survival model to a detailed dataset of Swedish patents to estimate how different financing 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,...
