Robert Skidelsky, “The Relevance of Keynes,” Cambridge Journal of Economics 35.1 (2011): 1–13.Skidelsky is Keynes’s biographer and his interpretation of Keynes is in fact very close to that of the Post Keynesian school, which is why his work is important. The interested reader looking for something more substantial can also read Skidelsky’s new book Keynes: The Return of the Master (Allen Lane, 2009). A reasonably good summary can be found here:New Keynesian macroeconomics. First, we have quite positive reviews of Skidelsky’s book by the liberal New Keynesians Krugman and Stiglitz:
Paul Krugman, “Keynes: The Return of the Master by Robert Skidelsky,” Guardian, 30 August 2009.In contrast, we have the conservative New Keynesian N. Gregory Mankiw in a remarkably cold review in the Wall Street Journal:
Joseph Stiglitz, “The Non-Existent Hand,” London Review of Books 32.8, 22 April 2010.
(this also has a letter by the Post Keynesian Paul Davidson clarifying Keynes’s views on uncertainty).
