  • Income Distribution Macroeconomics


    Working Paper No. 807 | June 2014

    Recent research stresses the macroeconomic dimension of income distribution, but no theory has yet emerged. In this note, we introduce factor shares into popular growth models to gain insights into the macroeconomic effects of income distribution. The cost of modifying existing models is low compared to the benefits. We find, analytically, that (1) the multiplier is equal to the inverse of the labor share and is about 1.4; (2) income distribution matters mostly in the medium run; (3) output is wage led in the short run, i.e., as long as unemployment persists; (4) capacity expansion is profit led in the full-employment long run, but this is temporary and unstable.

  • Financial Markets


    Working Paper No. 660 | March 2011

    This paper provides a brief exposition of financial markets in Post Keynesian economics. Inspired by John Maynard Keynes’s path-breaking insights into the role of liquidity and finance in “monetary production economies,” Post Keynesian economics offers a refreshing alternative to mainstream (mis)conceptions in this area. We highlight the importance of liquidity—as provided by the financial system—to the proper functioning of real world economies under fundamental uncertainty, contrasting starkly with the fictitious modeling world of neo-Walrasian exchange economies. The mainstream vision of well-behaved financial markets, channeling saving flows from savers to investors while anchored by fundamentals, complements a notion of money as an arbitrary numéraire and mere convenience, facilitating exchange but otherwise “neutral.” From a Post Keynesian perspective, money and finance are nonneutral but condition and shape real economic performance. It takes public policy to anchor asset prices and secure financial stability, with the central bank as the key public policy tool.
