5. Early Stiglitz as a precursor of Piketty, and the Stiglitz dissertation here (pdf).  The associated Econometrica piece is here (pdf).  Here is a JEL paper surveying the literature on growth and inequality (pdf).  Most useful yet, there is Bertola’s survey on distribution and growth (pdf).  You also should go back and read Pasinetti’s old papers from the 1960s.  These are old issues people, and there are no simple answers.  A lot of the current discussion is in fact moving the debate backwards from where it had been decades ago.
