This paper investigates exchange rate pass-through in Singapore using band-pass spectral regression techniques, allowing for asymmetric effects over the business cycle. First stage pass-through is estimated to be complete and relatively quick, confirming existing views that the exchange rate provides an effective tool to moderate imported inflation in Singapore. Asymmetric pass-through effects over the business cycle are also detected, with importers passing on a smaller share of exchange rate movements during boom periods as compared to recessions. This result suggest that Singapore’s exchange rate policy could afford to "lean against the wind," especially during cyclical expansions.

Singapore has addressed high inflation over the past years amid a tight labor market through several rounds of tightening of the exchange rate-based monetary policy. This paper estimates the exchange pass-through to inflation in Singapore with a particular focus on the role of labor market conditions. The paper first finds a strong exchange rate pass-through to inflation in Singapore, after accounting for the potential endogeneity of changes in the exchange rate. Further, it uncovers that labor market tightness dampens exchange rate pass-through and therefore could weaken monetary policy transmission. Overall, the results suggest that monetary policy should be more vigilant under a tight labor market condition. The paper then draws policy implications for taming inflation under tight labor market conditions.

Most trade is invoiced in very few currencies. Despite this, the Mundell-Fleming benchmark and its variants focus on pricing in the producer’s currency or in local currency. We model instead a ‘dominant currency paradigm’ for small open economies characterized by three features: pricing in a dominant currency; pricing complementarities, and imported input use in production. Under this paradigm: (a) the terms-of-trade is stable; (b) dominant currency exchange rate pass-through into export and import prices is high regardless of destination or origin of goods; (c) exchange rate pass-through of non-dominant currencies is small; (d) expenditure switching occurs mostly via imports, driven by the dollar exchange rate while exports respond weakly, if at all; (e) strengthening of the dominant currency relative to non-dominant ones can negatively impact global trade; (f) optimal monetary policy targets deviations from the law of one price arising from dominant currency fluctuations, in addition to the inflation and output gap. Using data from Colombia we document strong support for the dominant currency paradigm.

China’s exchange rate regime has undergone gradual reform since the move away from a fixed exchange rate in 2005. The renminbi has become more flexible over time but is still carefully managed, and depth and liquidity in the onshore FX market is relatively low compared to other countries with de jure floating currencies. Allowing a greater role for market forces within the existing regime, and greater two-way flexibility of the exchange rate, are important steps to build on the progress already made. This should be complemented by further steps to develop the FX market, improve FX risk management, and modernize the monetary policy framework.

''In summary, the book is valuable as a textbook both at the advanced undergraduate level and at the graduate level. It is also very useful for the economist who wants to be brought up-to-date on theoretical and empirical research on exchange rate behaviour.'' ""Journal of International Economics""

How should governments and central banks use monetary policy to create a healthy economy? Traditionally, policymakers have used such strategies as controlling the growth of the money supply or pegging the exchange rate to a stable currency. In recent years a promising new approach has emerged: publicly announcing and pursuing specific targets for the rate of inflation. This book is the first in-depth study of inflation targeting. Combining penetrating theoretical analysis with detailed empirical studies of countries where inflation targeting has been adopted, the authors show that the strategy has clear advantages over traditional policies. They argue that the U.S. Federal Reserve and the European Central Bank should adopt this strategy, and they make specific proposals for doing so. The book begins by explaining the unique features and advantages of inflation targeting. The authors argue that the simplicity and openness of inflation targeting make it far easier for the public to understand the intent and effects of monetary policy. This strategy also increases policymakers' accountability for inflation performance and can accommodate flexible, even "discretionary," monetary policy actions without sacrificing central banks' credibility. The authors examine how well variants of this approach have worked in nine countries: Germany and Switzerland (which employ a money-focused form of inflation targeting), New Zealand, Canada, the United Kingdom, Sweden, Israel, Spain, and Australia. They show that these countries have typically seen lower inflation, lower inflation expectations, and lower nominal interest rates, and have found that one-time shocks to the price level have less of a "pass-through" effect on inflation. These effects, in turn, are improving the climate for economic growth. The authors warn, however, that the success of inflation targeting depends on operational details, such as how the targets are defined and when they are announced. They also show that inflation targeting is not a panacea that can make inflation perfectly predictable or reduce it without economic costs. Clear, balanced, and authoritative, Inflation Targeting is a groundbreaking study that will have a major impact on the debate over the right monetary strategy for the coming decades. As a unique comparative study of what central banks actually do in different countries around the world, this book will also be invaluable to anyone interested in how economic policy is made.

Singapore: Selected Issues

We document that the U.S. dollar exchange rate drives global trade prices and volumes. Using a newly constructed data set of bilateral price and volume indices for more than 2,500 country pairs, we establish the following facts: 1) The dollar exchange rate quantitatively dominates the bilateral exchange rate in price pass-through and trade elasticity regressions. U.S. monetary policy induced dollar fluctuations have high pass-through into bilateral import prices. 2) Bilateral non-commodities terms of trade are essentially uncorrelated with bilateral exchange rates. 3) The strength of the U.S. dollar is a key predictor of rest-of-world aggregate trade volume and consumer/producer price inflation. A 1 percent U.S. dollar appreciation against all other currencies in the world predicts a 0.6–0.8 percent decline within a year in the volume of total trade between countries in the rest of the world, controlling for the global business cycle. 4) Using a novel Bayesian semiparametric hierarchical panel data model, we estimate that the importing country’s share of imports invoiced in dollars explains 15 percent of the variance of dollar pass-through/elasticity across country pairs. Our findings strongly support the dominant currency paradigm as opposed to the traditional Mundell-Fleming pricing paradigms.

Instead of focusing the debate about the conduct of monetary policy on whether the nominal exchange rate should be fixed or flexible, the focus should be on whether the monetary policy regime appropriately constrains discretion in monetary policymaking. Three frameworks deserve serious discussion as possible long-run strategies for monetary policy in Latin America. A hard exchange-rate peg, monetary targeting, and inflation targeting.

We show that the response of firm-level investment to real exchange rate movements varies depending on the production structure of the economy. Firms in advanced economies and in emerging Asia increase investment when the domestic currency weakens, in line with the traditional Mundell-Fleming model. However, in other emerging market and developing economies, as well as some advanced economies with a low degree of structural economic complexity, corporate investment increases when the domestic currency strengthens. This result is consistent with Diaz Alejandro (1963)—in economies where capital goods are mostly imported, a stronger real exchange rate reduces investment costs for domestic firms.
