Kapital for the Twenty-First Century?

Thomas Piketty’s Capital in the Twenty-First Century is a weighty book, replete with good information on the flows of income, transfers of wealth, and the distribution of financial resources in some of the world’s wealthiest countries. But it is not a very sound guide to policy. And despite its great ambitions, his book is not the accomplished work of high theory that its title, length, and reception (so far) suggest.
