Identifying Monetary Policy In A Small Open Economy Under Flexible Exchange Rates

An important hurdle in analyzing interest rate targeting is that standard models usually lead to price level or inflation rate indeterminacy. This paper develops a simple framework in which such problems do not arise because the bonds whose interest rate is controlled provide liquidity services. This framework is used to examine interest rate targeting in a small open economy under predetermined exchange rates. A permanent increase in the interest rate has no real effects. In contrast, a temporary increase in the interest rate leads to higher consumption and to a current account deficit that worsens over time.

This paper revisits Canada's pioneering experience with floating exchange rate over the period 1950-1962. It examines whether the floating rate was the best option for Canada in the 1950s by developing and estimating a New Keynesian small open economy model of the Canadian economy. The model is then used to conduct a counterfactual analysis of the impact of different monetary policies and exchange rate regimes. The main finding indicates that the flexible exchange rate helped reduce the volatility of key macro-economic variables. The Canadian monetary authorities, however, clearly did not understand all of the implications of conducting monetary policy under a flexible exchange rate and a high degree of capital mobility. The paper confirms that monetary policy was more volatile in the post-1957 period and Canada's macroeconomic performance suffered as a result.

We analyze coordination of monetary and exchange rate policy in a two-sector model of a small open economy featuring imperfect substitution between domestic and foreign financial assets. Our central finding is that management of the exchange rate greatly enhances the efficacy of inflation targeting. In a flexible exchange rate system, inflation targeting incurs a high risk of indeterminacy where macroeconomic fluctuations can be driven by self-fulfilling expectations. Moreover, small inflation shocks may escalate into much larger increases in inflation ex post. Both problems disappear when the central bank leans heavily against the wind in a managed float.

This paper investigates the effects of unconventional monetary policy in a small open economy. Using recently proposed shadow interest rates to capture unconventional monetary policy at the zero lower bound (ZLB) we estimate a Bayesian structural vector autoregressive model for Canada - a useful case where foreign shocks can be proxied by U.S. variables alone. We find that, during the ZLB period, Canadian unconventional monetary policy increased output (measured by industrial production) by 0.013 percent per month on average while US unconventional monetary policy raised Canadian output by 0.127 percent per month on average. Our results demonstrate the effectiveness of domestic unconventional monetary policy and the strong positive spillover effects that foreign unconventional monetary policies can have in a small open economy.

In the past few years, a number of central banks have adopted inflation targeting for monetary policy. The author provides an introduction to inflation targeting, with an emphasis on analytical issues, and the recent experience of middle- and high-income developing countries (which have relatively low inflation to begin with, and reasonably well-functioning financial markets). After presenting a formal analytical framework, the author discusses the basic requirements for inflation targeting, and how such a regime differs from money, and exchange rate targeting regimes. After discussing the operational framework for inflation targeting (including the price index to monitor the time horizon, the forecasting procedures, and the role of asset prices), he examines recent experiences with inflation targets, providing new evidence on the convexity of the Phillips curve for six developing countries. His conclusions: Inflation targeting is a flexible policy framework that allows a country's central bank to exercise some degree of discretion, without putting in jeopardy its main objective of maintaining stable prices. In middle- and high-income developing economies that can refrain from implicit exchange rate targeting, it can improve the design, and performance of monetary policy, compared with other policy approaches that central banks may follow. Not all countries may be able to satisfy the technical requirements (such as adequate price data, adequate understanding of the links between instruments, and targets of monetary policy, and adequate forecasting capabilities), but such requirements should not be overstated. Forecasting capability can never be perfect, and sensible projections always involve qualitative judgment. More important, and often more difficult, is the task of designing, or improving an institutional framework that would allow the central bank to pursue the goal of low, stable inflation, while maintaining the ability to stabilize fluctuations in output.

This book contains the papers, comments, and the discussion at a conference on "Flexible Exchange Rates and Stabilization Policy", held at Saltsjobaden, Stockholm, August 26–27, 1975. The papers integrate the flexible exchange rates theory with macro theory and stabilization policy analysis. .
