This article develops an OLG model with random relocations of agents among more-than-two islands, wherein asymmetric liquidity shocks are observed. The model exhibits suboptimality of the Friedman rule. Furthermore, it is shown that there is no room for monetary policy to improve social welfare...

da Costa and Werning (2005) prove that the Friedman rule of setting nominal interest rate to zero is locally optimal in a monetary model where each consumer receives a privately observed skill shock and the government uses incentive compatible non-linear income taxation. In this paper, we show...

We highlight one difference in predictions between Romer's expanding variety model and the Schumpeterian quality-ladder model, when there exists a cash-in-advance (CIA) constraint on manufacturing. In the expanding variety model, a higher nominal interest rate decreases growth, and a negative...
