The Piketty-Kaldor paradox of growth: Reply to Medlen

摘要

Despite the yawning gap between their time horizons, there are a few interesting similarities between Piketty and Keynes. A graph of the Piketty-Kaldor paradox of growth (where a lower growth rate leads to a higher saving rate) is similar to the familiar graph of the Keynesian paradox of thrift (where a lower saving rate leads to higher investment). Keynes showed that cautious spending can lead to recession, and Piketty showed that cautious growth can lead to maldistribution.
