The Thomas Piketty-Angus Deaton Link

David Warsh also suspects it is there:

With its emphasis on growth and development, as opposed to the inequality that  inevitably accompanies it, [Deaton's] The Great Escape [Health, Wealth, and the Origins of Inequality] makes an ideal companion to Thomas Piketty’s Capital in the Twenty-First Century (Harvard, 2014). That, too, may have been part of what the Nobel committee had in mind.
