You should be interested in a comment I have on Capital in the 21st Century, as well as an interview with Trevor Evans of the Economics School in Berlin on the EU elections. I put these together because Thomas Piketty and some of his colleagues have endorsed a softer version of the Maastricht criteria, which is similar to suggestions by the Glienicker Group in Germany.
More consistent with views expressed in the Recovery is the Modest Proposal 4.0 from James Galbraith and Yanis Varoufakis.
