*The Economics of Inequality*

That is the new — well sort of new — Thomas Piketty book.  It was first published in France in 1997 and then updated several times through 2014, though we are told most of the book has kept its original structure.  It is a good, short read and will appeal to anyone with an interest in Piketty and “that sort of thing.”  The full-blown g > r model is not here, but you can see Piketty edging into being Piketty, with plenty of talk about capital-labor substitutability.
