Inflation targeting is a monetary policy framework where central banks set explicit medium-term inflation targets and use tools like interest rate changes to steer actual inflation toward those targets. This approach has been adopted by many central banks, including those in advanced economies such as the European Central Bank and the US Federal Reserve, as well as emerging market economies. The success of inflation targeting is attributed to increased economic stability and transparency. However, central banks may face challenges in meeting their targets, and there are debates about the effectiveness of this approach in different economic contexts. This raises the question of whether inflation-targeting central banks implicitly target the price level and how their policies may vary across countries.

What You'll Learn
The impact of monetary strategies on inflation persistence
The rationale behind inflation targeting is the belief that maintaining price stability is crucial for supporting the long-term growth of an economy. Central banks aim to achieve this price stability by influencing interest rates, which are used as a primary monetary instrument. The conventional understanding is that raising interest rates curbs inflation by cooling down the economy, while lowering interest rates boosts inflation by stimulating economic activity.
The success of inflation targeting varies across countries. Notable examples of successful implementation include New Zealand, Canada, and the United Kingdom, which were among the first adopters in the early 1990s. The Bank of England, in particular, has been commended for its transparency and innovative communication strategies, which have influenced other central banks. However, countries like Australia, Sweden, and New Zealand have been found to exhibit heterogeneity in their application of inflation targeting, indicating that the impact of this strategy may depend on a country's specific context.
While inflation targeting has led to significant reductions in inflation rates, central banks do not always meet their targets. In response to missed targets, central banks may adjust their targets in subsequent periods to align with the actual inflation rate, particularly in low-performance economies. This behaviour can introduce challenges in achieving equilibrium determinacy and may even destabilize inflation expectations.
The adoption of inflation targeting has been influenced by economic transitions and crises. For instance, Armenia, the Czech Republic, Hungary, and Poland adopted this strategy during their transition from centrally planned to market economies. Additionally, several emerging market economies embraced inflation targeting after the 1997 crisis, which prompted the abandonment of fixed exchange rate pegs.
In conclusion, the impact of monetary strategies, such as inflation targeting, on inflation persistence is multifaceted. While inflation targeting has contributed to reduced inflation rates and increased economic stability, its effectiveness depends on various factors, including a central bank's performance, credibility, and the specific economic context of its country. Further, the strategy has limitations in dealing with positive supply shocks and requires a significant amount of information for accurate forecasting.

Price-level targeting as an alternative to inflation targeting
Price-level targeting is a monetary policy framework that can be used to achieve price stability. It involves a central bank increasing or decreasing the supply of money and credit in the economy to achieve a specified price level. This is in contrast to inflation targeting, where a central bank estimates and makes public a projected or "target" inflation rate and then uses tools such as interest rate changes to steer actual inflation towards that target.
The main difference between inflation targeting and price-level targeting lies in the consequences of missing the target. Under inflation targeting, past mistakes and shocks are treated as "bygones", with the focus on achieving average (on-target) inflation in future years regardless of the current inflation level. On the other hand, price-level targeting implicitly includes past price changes and commits to reversing any deviations from past targets. For example, if the price level falls below its target, the central bank would need to accelerate monetary expansion to meet its target in the following year.
Price-level targeting has the potential to bring about larger welfare gains, amounting to 0.4% of GDP per year, due to the additional welfare gains associated with a lower trend rate of inflation. It is also found to be a good mechanism for helping the economy recover from deflationary shocks driving monetary policy to the "zero bound". This is particularly relevant when nominal interest rates are close to zero, as it can encourage a more aggressive expansionary policy compared to a simple inflation target.
However, price-level targeting has not been widely adopted by central banks. The only serious attempt at price-level targeting was by the Swedish central bank in the 1930s, based on the theories of Swedish economist Knut Wicksell. This policy was later blamed for aggravating unemployment in Sweden during that period.
In conclusion, price-level targeting offers a potential alternative to inflation targeting, particularly in low-interest rate environments, by providing a way to achieve price stability and potentially higher GDP growth in a deflationary environment. However, it has seen limited adoption by central banks due to concerns about its impact on unemployment and other economic factors.

The role of central banks in controlling inflation
Central banks play a crucial role in controlling inflation through a technique called inflation targeting, which involves setting explicit targets for the inflation rate over the medium term and announcing these targets to the public. This approach is based on the assumption that maintaining price stability is essential for supporting the long-term growth of an economy, and price stability is achieved by controlling inflation.
Central banks, as the makers of monetary policy, use various tools to steer actual inflation towards their announced targets. One of the primary tools is adjusting interest rates, which tend to have an inverse relationship with inflation rates. By raising or lowering interest rates, central banks can influence economic activity, either cooling it down to curb inflation or boosting it to increase inflation and achieve their targeted inflation rate.
The success of inflation targeting relies on the central bank's ability to conduct monetary policy with some degree of independence from government influence. While no central bank can be entirely independent, the discretion to choose the instruments used to achieve the desired inflation rate is critical. Additionally, transparency is essential, as it helps manage expectations and maintain credibility.
Several countries have adopted inflation targeting, including New Zealand, Canada, the United Kingdom, Armenia, the Czech Republic, Hungary, and Poland. Some central banks, such as the European Central Bank (ECB), do not explicitly identify as inflation targeters but are committed to achieving low inflation and maintaining price stability.
While inflation targeting has been successful in reducing inflation rates in many countries, central banks do not always meet their targets. In response to missed targets, central banks may adjust their targets to close the gap between the actual and desired inflation rates, particularly in low-performance or low-credibility central banks. However, this behaviour can lead to challenges in achieving equilibrium determinacy and may potentially destabilize inflation expectations.

The transmission mechanism from policy instruments to inflation
Firstly, changes to monetary policy affect interest rates in the economy. Central banks, such as the US Federal Reserve or the European Central Bank, adjust the supply of money in the economy to influence interest rates. For example, a central bank may lower the cash rate target, reducing interest rates in their country relative to the rest of the world. This makes it less lucrative for investors, reducing the demand for assets in that country and its currency, ultimately leading to a lower exchange rate.
Secondly, changes to interest rates influence economic activity and inflation. Lower interest rates increase aggregate demand by encouraging spending, as consumers are incentivised to spend on goods and services rather than saving. This creates a lag as the supply of goods and services takes time to respond to the increased demand, leading to upward pressure on prices. Businesses increase their prices to match the higher demand, resulting in higher inflation.
Additionally, the transmission mechanism operates through various channels beyond business investment and housing. These include asset prices and the exchange rate. An appreciated exchange rate, for instance, can reduce import prices and raise real wages, both of which contribute to lower inflation. Conversely, a depreciated exchange rate makes foreign goods and services more expensive, potentially impacting inflation.
The transmission of monetary policy to inflation is also influenced by expectations. If workers anticipate higher inflation, they may demand larger wage increases, contributing to higher inflation. By setting an inflation target and communicating future hikes, central banks can anchor these expectations, reducing uncertainty and increasing confidence in the economy. This, in turn, affects saving and investment decisions, impacting consumption, housing investment, and business investment.
Overall, the transmission mechanism from policy instruments to inflation involves a complex interplay of factors, including interest rates, exchange rates, and economic expectations. Central banks employ various tools, such as interest rate adjustments and forward guidance, to influence these factors and achieve their inflation targets.

The challenges of achieving equilibrium determinacy
Inflation targeting is a technique adopted by many central banks to control the general rise in the price level. This involves a central bank estimating and making public a projected, or "target," inflation rate, and then using tools such as interest rate changes to steer actual inflation toward that target. This approach is based on the understanding that interest rates and inflation rates tend to move in opposite directions.
Multiple Objectives
Inflation targeting allows central banks to address other economic objectives over the short term, such as smoothing output. While this provides flexibility, it also introduces complexities in achieving equilibrium. The central bank must balance these multiple objectives, which may involve trade-offs and can impact the unique equilibrium solution.
Medium-Term Focus
Inflation targeting typically operates within a medium-term horizon, usually over two to three years. This medium-term focus means that policymakers are not compelled to meet targets on a period-by-period basis. As a result, the challenge arises in managing the trade-off between reacting to current inflation and achieving the target over the given time frame.
Interest Rate Dynamics
The relationship between interest rates and inflation is crucial in inflation targeting. However, the dynamics of interest rates can be complex. The Taylor principle, which suggests that short-term rates must rise sufficiently in response to inflation, may not always hold. Additionally, the expectations of high short-term rates can become self-fulfilling, causing long-term rates to rise, which then influences the central bank's decisions on short-term rates.
Independence of Central Bank
Inflation targeting requires a central bank to have some degree of independence in conducting monetary policy. While complete independence from government influence is not feasible, the central bank must have autonomy in choosing the instruments to achieve the desired inflation rate. Achieving equilibrium in this context may be challenging due to the potential for conflicting objectives and influences from the government.
Economic and Market Conditions
The success of inflation targeting depends on the central bank's ability to control the money supply and the stability of the relationship between money growth and inflation over time. Financial market innovations and changes in the demand for money can impact this stability. Additionally, countries with flexible exchange rates may face challenges in directly targeting inflation due to the complex "transmission mechanism" from policy instruments to inflation.

Frequently asked questions
Inflation targeting is a monetary policy where a central bank sets a target for the inflation rate over the medium term and makes this target public. The central bank then uses monetary policy instruments, such as interest rates, to steer actual inflation toward the target.
Central banks adopt inflation targeting to achieve price stability, which is thought to support the long-term growth of the economy. Inflation targeting also provides a rule-like framework that allows central banks to react to shocks and address other short-term objectives.
Central banks forecast the future path of inflation and compare it to the target inflation rate. They then use monetary policy instruments, primarily interest rates, to adjust actual inflation. For example, raising interest rates typically cools the economy and helps curb inflation.
Many central banks have adopted inflation targeting or its main elements, including the European Central Bank, the US Federal Reserve, and the central banks of Armenia, the Czech Republic, Hungary, Poland, and the United Kingdom. New Zealand and Canada were among the first countries to implement inflation targeting in the early 1990s.
