Inflation targeting (IT) serves as monetary policy framework in several advanced economies, where it has enhanced policy transparency and accountability. The paper considers its wider applicability to developing countries. The prerequisites for a successful IT framework are identified as an ability to carry out an independent monetary policy (free of fiscal dominance or commitment to another nominal anchor, like the exchange rate) and a quantitative framework linking policy instruments to inflation. These prerequisites are largely absent among developing countries, though several of them could with some further institutional changes and an overriding commitment to low inflation make use of an IT framework.

Inflation distorts prices, erodes savings, discourages investment,stimulates capital flight, inhibits growth, and makes economic planning anightmare. During the past decade, several advanced economies have takena new approach to the age-old problem of controlling inflation throughmonetary policy known as "inflation targeting." This pamphlet explainsthe requirements of putting the new policy in place, the experience of the countries that have tried it, and whether it has applicability todeveloping countries.

Experience with monetary targeting suggests that although it successfully controlled inflation in Switzerland and especially Germany, the special conditions that made it work reasonably well in those two countries are unlikely to be satisfied elsewhere. Inflation targeting is more likely to improve economic performance in countries that choose to have an independent domestic monetary policy, but there are subtleties in how inflation targeting is done. Lessons from industrial countries should be useful to central banks designing a framework for monetary policy.

In closed or open economy models with complete markets, targeting core inflation enables monetary policy to maximize welfare by replicating the flexible price equilibrium. We analyze this result in the context of developing economies, where a large proportion of households are credit constrained and the share of food expenditures in total consumption expenditures is high. We develop an open economy model with incomplete financial markets to show that headline inflation targeting improves welfare outcomes. We also compute the optimal price index, which includes a positive weight on food prices but, unlike headline inflation, assigns zero weight to import prices.

This paper provides an overview of inflation targeting frameworks and macroeconomic performance under inflation targeting. Inflation targeting frameworks are generally quite similar across countries, and a broad consensus has developed in favor of "flexible" inflation targeting. The evidence shows that, although inflation target ranges are missed frequently in most countries, the inflation and growth performance under inflation targeting compares very favorably with performance under alternative frameworks. Inflation targeters also tentatively appear to be coping better with the commodity price and financial shocks in 2007-2009 than non-inflation targeters. Key issues going forward include adapting inflation targeting to emerging market and developing countries, and incorporating financial stability issues into the framework.

This is the fifth chapter of a forthcoming monograph entitled "On Implementing Full-Fledged Inflation-Targeting Regimes: Saying What You Do and Doing What You Say." It examines whether certain conditions have to be met before emerging economies can adopt an inflation-targeting regime and provides some empirical evidence on the matter. The issues analyzed are the priority of inflation targeting over other goals, the absence of fiscal dominance, central bank independence, the degree of control over the policy interest rate, a sound methodology for forecasting, and the soundness of financial institutions and markets, and resilience to changes in exchange rates and interest rates.
