"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."

“The overall importance of capital today, as noted, is not very different from what it was in the eighteenth century. Only its form has changed: capital was once mainly land but is now industrial, financial, and real estate. We also know that the concentration of wealth remains high, although it is noticeably less extreme than it was a century ago. The poorest half of the population still owns nothing, but there is now a patrimonial middle class that owns between a middle and a third of total wealth, and the wealthiest ten percent now own only-two thirds of what there is to own rather than nine-tenths.”

“Let it be said at once: Trump’s victory is primarily due to the explosion in economic and geographic inequality in the United States over several decades and the inability of successive governments to deal with this.”

“It is time to change the political discourse on globalization: trade is a good thing, but fair and sustainable development also demands public services, infrastructure, health and education systems. In turn, these themselves demand fair taxation systems. If we fail to deliver these, Trumpism will prevail.”

“The tragedy is that Trump’s program will only strengthen the trend towards inequality.”

“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.”

“We know something about billionaire consumption, but it is hard to measure some of it. Some billionaires are consuming politicians, others consume reporters, and some consume academics.”
