The mother of invention

Migration, according to Carsten Fink, Ernest Miguelez, Julio Raffo, who've exploited a unique data base;
Patents filed under the Patent Cooperation Treaty contain information on both the residence and the nationality of inventors....

Among their findings;
The US is by far the most popular destination for migrant 57% of the world’s inventors that reside outside their home country. Moreover, there are 15 times as many immigrant inventors in the US as there are US inventors residing abroad. Switzerland, Germany, and the UK also attract considerable numbers of inventors. Interestingly, though, Germany and the UK see more inventors emigrating than immigrating. Canada and France similarly show a negative net inventor immigration position.
Immigrant inventors account for 18% of all inventors residing in the US. Several small European countries see even higher immigration rates –notably, Belgium (19%), Ireland (20%), Luxembourg (35%), and Switzerland (38%). Among the larger European countries, the UK (12%) shows a relatively high share of immigrant inventors. By comparison, foreign nationals only account for 3% to 6% of all inventors in Germany, France, Italy and Spain. Japan is the only high-income economy with an inventor immigration rate of less than 2%. 
And, in a don't-stop-the-presses revelation;
We find that many of the variables that explain overall migration also explain inventor migration. In particular, economic incentives positively affect inventors’ decisions to migrate and the costs of relocating to another country exert a negative influence on these decisions.
