Description

The standard macroeconomic DSGE model used by economic policy and central bank planners cannot handle questions of fragility and stability because it assumes away complex market dynamics. A promising alternative approach replaces rational expectations with adaptive expectations and a public price system (one price per market) with a multidimensional private price system. Market equilibrium in this approach consists in 'almost-clearing' in all markets and a very small standard deviation of price in each market.
