French economist Thomas Piketty has come out with a new book. The 1200-page Capital and Ideology is a followup to Capital in the 21st Century, a surprise bestseller when it was released a few years ago. The book just came out in French (English readers will need to wait until March) so details are still sparse, but The Guardian has a short preview.

Among the proposals in the book are that employees should have 50% of the seats on company boards; that the voting power of even the largest shareholders should be capped at 10%; much higher taxes on property, rising to 90% for the largest estates; a lump sum capital allocation of €120,000 (just over £107,000) to everyone when they reach 25; and an individualised carbon tax calculated by a personalised card that would track each person’s contribution to global heating. In an interview with the French weekly news magazine L’Obs, Piketty made no apologies for the impact his ideas would have on the stock market. He said: “[Yes], it will also affect the price of real estate that is crazy in Paris, and it will allow new social groups to become owners and shareholders.”

Branko Milanovic, an expert on global inequality, has written an early review.
