Policy evaluation based on the estimation of dynamic stochastic general equilibrium models with aggregate macroeconomic time series rests on the assumption that a representative agent can be identified, whose behavioural parameters are independent of the policy rules.

Policy evaluation based on the estimation of dynamic stochastic general equilibrium models rests on the assumption that a representative agent can be identified, whose behavioural parameters are policy-independent. Building on earlier work by Geweke [1985], this paper shows that in the presence...
