John Oliver on Patent Trolls

The topic of patent trolls was already featured here before. Apparently it’s so hot right now that it got covered in Last Week Tonight with John Oliver. Check it out, it’s really fun to watch!

Den Pobedy

Today, in continental Europe, we remember the end of World War II. The German Bundestag commemorates the victims of the war in a quiet and devout mood. At 9 in the morning, historian Heinrich August Winkler as well as the president of the parliament, Norbert Lammert, give a speech. Besides some media coverage, there won’t be other official public events. Things will be a little different in Moscow tomorrow. Since in Russia it was already after midnight when Nazi Germany signed its capitulation in 1945, “Den Pobedy” or “Victory Day” is celebrated on May 9. Continue reading Den Pobedy

Economics Unchained

cropped-logo_edited_single

I recently published an article on Economics Unchained. The website was created by one of my former classmates at Mannheim and serves as a platform for young economists to publicize extended abstracts of their research. Much like voxeu for people who are still early in their career. That’s a great idea, if you ask me. The homepage is still at the beginning. It thrives on the participation of the community. So go ahead and share your thoughts! It would be great to see the concept taking off.

Talking About Modern Arts

Intellectual Property Rights (IPR), such as patents, trademarks, and copyrights, are an important institution of modern societies. They aim to allow the commercialization of creative work, and thereby provide economic incentives for inventions and innovations. But the optimal scope of IPR is subject of ongoing debates among scholars. Continue reading Talking About Modern Arts

The Econ 101 of Agriculture

Wolfram Schenker from Columbia University gave a talk about the impact of climate change on agricultural production at ZEW. The part which struck me the most, I found out later, is part of a paper published in the American Economic Review (Roberts and Schlenker, 2013). Seems like I have a good taste… Continue reading The Econ 101 of Agriculture

The AncientBiotics Project

Just because recently I was so much into antibiotics on this page, here is a fascinating story about a research team from Nottingham which rebrewed a thousand-year-old recipe from medieval sources and found the substance to be highly effective against MRSA, a bacterium which is largely resistant to common antibiotic treatments. Usually I’m not a big fan of interdisciplinary research projects, as they are too often only a straw man, but these results are, as the researchers themselves put it, “absolutely astonishing”.

The fact that all ingredients alone, such as onion, garlic, and alcohol, show only a mild impact on bacteria growth but develop their true potential in the exact combination discovered in the 10th century puts into perspective theories (which were recently discussed elsewhere) that deny the medieval population the ability to make use of experimentation and the scientific method. In general, a lack of breakthrough inventions in science did not seem to be the problem throughout human history. It’s just hard to understand why such an invaluable knowledge like the invention of effective antibiotic treatments did not have a larger impact and spread to a wider geographical area. This channel of knowledge spillovers, the “standing on shoulders of giants” part of science, seems to have only opened up in modern times.

I can only recommend you to watch this video…

Beware of Trolls (Part 2)

Read the first part of this post, with an introduction into the business model of patent trolls, here!

Let’s get into the economics. Think of two companies, call them “Pear” and “Samson”, who are both active in the smart phone business and each making a profit of \pi_P = \pi_S = \pi.Pear But in their production process both firms risk to infringe a patent held by a troll with probability \theta. Choi and Gerlach assume that when a troll files a law suit and actually wins in court, he can extract a licensing fee of \pi/2, which results from bargaining with symmetric bargaining power (Nash solution).
