How do wealth- and capital-output ratios evolve in the long run, and w — Thomas Piketty

"How do wealth- and capital-output ratios evolve in the long run, and why? Until recently it was difficult to properly address this question, for one simple reason: national accounts were mostly about flows, not stocks. Economists had at their disposal a large body of historical series on flows of output, income and consumption – but limited data on stocks of assets and liabilities. When needed, for example for growth accounting exercises, estimates of capital stocks were typically obtained by cumulating past flows of saving and investment. This is fine for some purposes, but severely limits the set of questions one can ask."

"Ceta, the EU-Canada free trade deal, should be rejected. It is a treaty which belongs to another age. This strictly commercial treaty contains absolutely no restrictive measures concerning fiscal or climate issues. It does, however, contain a considerable reference to the “protection of investors”. This enables multinationals to sue states under private arbitration courts, bypassing the public tribunals available to one and all. The legal supervision proposed is clearly inadequate, in particular concerning the key question of the remuneration of the arbitrators-cum-referees and will lead to all sorts of abuses. At the very time when American legal imperialism is gaining in strength and imposing its rules and its dues on our companies, this decline in public justice is an aberration. The priority, on the contrary, should be the construction of strong public authorities, with the creation of a prosecutor, including a European state prosecutor, capable of enforcing their decisions."
