Research interests

Jonas' research focuses on technology management and intellectual property strategies. Specifically, he investigates so-called Open IP strategies, such as Tesla Motors' patent pledge from 2014 and Toyota's patent pledge from 2015. Jonas uses agent-based modeling to replicate individual, heterogeneous firms and consumers decision-making processes in order to measure their effects on the general market.
