Matthew Yglesias in Vox:

Thomas Piketty’s Capital in the 21st Century is the most important economics book of the year, if not the decade. It’s also 696 pages long, translated from French, filled with methodological asides and in-depth looks at unique data, packed with allusions to 19th century novels, and generally a bit of a slog.

The good news is that there’s no advanced math, and anyone who puts in the time can read the book. But if you just want the bottom line, we have you covered.

And a more academic one at Harvard Business Review.
