We all know the book: it’s been hailed as one of the most important documents on how the world economy works, or doesn’t work, and it’s been a colossal bestseller. But how many of us who bought or borrowed Thomas Piketty’s Capital in the Twenty-First Century have read more than a fraction of its 696 pages? How many of Piketty’s ground-shaking concepts have gone unappreciated for want of intellectual stamina? Deliverance is at hand in the form of Pocket Piketty, written in clear and accessible prose by an experienced economist and teacher whose work was relied on by Piketty for his masterpiece. In this handy and slim volume, Jesper Roine explains all things Piketty.
