This is an interesting read. Francesco Saraceno discusses with Prof. Hans-Werner Sinn about the arguments in two of the latter’s writings. I think it shows very well how much German economics lives in a bubble of its own, and how big the gap is between the various views of economic reality (if you could call the German view that).
Also, Finland did its homework (in terms of the EMU trade balance structure!) – where it used to have a trade surplus, it has a trade deficit as of 2014. In Saraceno’s words: Finland got rid of its excessive savings (while the Netherlands, Germany and Austria did not). Another time I would write more about what that means.
