Tyler Cowen writing at Marginal Revolution:
For the last few weeks there have been three models in the running:
1. The Greek government is calling the Germans Nazis because they figure Grexit is coming no matter what and they want to get the populace riled up as a distraction from the disasters, or
2. The Greek government will cave so cravenly on the substance that they want to have it on the record books that they supplied some expressive goods for a few weeks’ time, namely insulting the Germans and claiming that the Troika is dead and buried, or
3. The Greek government is simply full of out-of-control, ideological maniacs.
Right now it is looking like #2 … Arguably the insults and posturing have narrowed the possible bargaining space by hurting feelings all around.
