A Note on the Stability of Full Employment


  • Hansjorg Klausinger


This note investigates the stability properties of the Keynesian macro-model under the assumption of slow adjustment of nominal wages and expectations of inflation. First, the stability conditions of the 'flexible-interest-rate regime' are related to those derived by Cagan (1956) and Tobin (1975), emphasising the potentially destabilising effect of wage flexibility. Then, taking the restriction of a zero floor to the nominal interest rate into account it is shown that the model exhibits 'corridor stability'. From this follows the conjecture that increasing the rate of steady-state inflation makes it 'more probable' that the system returns to full-employment after a shock of given size.
