Singapore's unique monetary policy consists of a managed exchange rate framework that can be characterized as a Taylor-like reaction function with the nominal devaluation rate instead of the nominal interest rate as the main policy instrument. We build a small open economy New Keynesian model to...

This paper introduces a novel monetary policy framework where the exchange rate becomes the central instrument. Using Singapore as a case study, it explores the Monetary Authority's adoption of the exchange rate as the primary tool since 1981, diverging from conventional approaches centered on...

This paper analyzes how monetary policy responds to exchange rate movements in open economies, paying particular attention to the interaction between monetary policy and exchange rate movements. We address this issue using a structural VAR model that is identified using a combination of sign and...

The empirical VAR literature on the monetary transmission mechanism in closed economies has been successful in providing evidence with which theoretical models of the monetary transmission mechanism are now confronted. The empirical VAR literature on the monetary transmission mechanism in open...

International spillovers and exchange rate dynamics are examined in a two-country dynamic optimizing model that allows for home-product bias in consumption patterns: at given relative prices the ratio of home goods consumed to foreign goods consumed is higher in the home country. The setup nests...

This paper evaluates the performance of simple policy rules in an open economy. By introducing a high degree of exchange rate uncertainty we find that policy rules with an important feedback from movements in the real exchange rate are very robust to uncertainty about the true exchange rate...

We lay out a small open economy version of the Calvo sticky price model, and show how the equilibrium dynamics can be reduced to simple representation in domestic inflation and the output gap. We use the resulting framework to analyze the macroeconomic implications of three alternative...

We present a portfolio model of financial intermediation in which currency choice is determined by hedging decisions on both sides of a bank's balance sheet. We show that minimum variance portfolio (MVP) allocations provide a natural benchmark to estimate the scope for dollarization of assets...

Distortions introduced by targeting nominal income growth, or an exchange rate peg, in the trade-off between inflation and output in the stabilization of shocks to supply and terms of trade cannot be eliminated simultaneously. If supply shocks are optimally stabilized, targeting an exchange rate...

We develop an extension of the open economy New Keynesian model in which agents are boundedly rational à la Gabaix (2020). Our setup nests rational expectations (RE) as a special case and it can successfully mitigate many “puzzling” aspects of the relationship between exchange rates and...
