Abstract

This paper explores the role of currency and banking as competing sources of liquidity services for households within the workhorse open-economy New Keynesian model. I derive the equilibrium conditions that determine an open-economy equation of exchange and, by modeling the banking transformation of deposits into credit, I also identify a corresponding money multiplier equation. From that, I argue that in equilibrium the model establishes a link between credit and monetary aggregates on the one hand and poorly-measured global slack on the other hand that can be exploited to explain the trade-offs that monetary policy faces (particularly the open-economy Phillips curve). I also argue that ignoring the role of globalization can be an important factor in explaining the apparent poor performance of purely domestic monetary aggregates that has often been cited to motivate the use of cashless models. Finally, I conclude that monetary aggregates can be a powerful tool for monetary policymaking when global rather than domestic Divisia aggregates are considered. Moreover, I also show its significance for the design of monetary policy based on balance sheet policies and for understanding the dynamics of money and inflation.
