A Keynesian Dynamic Stochastic Disequilibrium model for business cycle analysis
No 1701, Working Papers from New School for Social Research, Department of Economics
A Dynamic Stochastic Disequilibrium (DSDE) model is proposed for business cycle analysis. Unemployment arises from job rationing due to insucient aggregate spending. The nominal wage is taken as a policy variable subject to a collective Nash bargaining process between workers and rms with the state of the labor market a ecting the relative bargaining power. A precautionary saving motive arising from an uninsurable risk of permanent income loss implies an equilibrium relation between consumption, income and wealth. The DSDE model di ers from the corresponding Dynamic Stochastic General Equilibrium (DSGE) model with labor market clearing in important respects: (i) Output is determined from the demand side and not from the supply side; (ii) The steady-state interest rate cannot be interpreted as a natural rate; (iii) It has to be smaller than the rate of economic growth in order for a steady state to exist; (iv) Determinacy of the solution requires the monetary policy response to in ation to be high (low) at low (high) steady-state interest rates; (v) Fighting in ation is stabilizing in the active monetary policy regime but destabilizing in the passive monetary policy regime; (vi) Macroeconomic responses to monetary policy and productivity shocks are similar to those of the DSGE model but give more weight to quantity adjustment and predict the real wage to increase with productivity.
