This paper investigates the effects generated by limited asset market participation on optimal monetary and fiscal policy, where monetary and fiscal authorities are independent and play strategically. It shows that: (i) both the long run and the short run equilibrium require a departure from zero inflation rate; (ii) in response to a markup shock, fiscal policy becomes more aggressive as the fraction of liquidity constrained agents increases and price stability is no longer optimal even under Ramsey; (iii) overall, optimal discretionary policies imply welfare losses for Ricardians, while liquidity constrained consumers experience welfare gains with respect to Ramsey.
