case that wealth, and accumulated wealth, tends to stay where it lands: and with the passage of time, just gets bigger and bigger. But how many of us who bought or borrowed the book - or even, perhaps, reviewed it - have read more than a fraction of its 696 pages? And how many of Piketty's groundshaking concepts have gone unappreciated, all 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 - and one whose work was relied on by Piketty for his masterpiece. In this handy and slim volume, Jesper Roine explains all things Piketty. Jesper Roine is an expert on wealth and income inequality, as well as one of the researchers who has contributed to the World Top Incomes Database upon which Piketty's research is based. He is an associate professor of Economics at SITE at the Stockholm School of Economics and has been published, extensively, on the topic of income and wealth inequality. Together with his colleague Daniel Waldenstrom at Uppsala University, he is responsible for the Swedish data on long-run income and wealth inequality used in Thomas Piketty's 'Capital in the Twenty-First Century'.
