Final answer:
Policymakers aim to maintain stable inflation to support economic stability, minimize risks, and encourage competition, using monetary policy as a key tool. High inflation can lead to significant economic and political consequences, thereby reinforcing the need for low and stable inflation.
Step-by-step explanation:
Policymakers strive to maintain a stable rate of inflation to ensure economic stability and growth. By using monetary policy, they can minimize the risk of high inflation, which in the long term can lead to undesirable risks and trade-offs, such as reduced purchasing power and distraction from productive activities. Stable inflation rates also contribute to minimizing exchange rate fluctuations, thereby encouraging domestic and international competition and helping to sustain economic growth.
High-income economies notably have a political consensus and economic tools to keep inflation low and stable. Instances of high inflation can result in increased costs for businesses and individuals, and may even have political repercussions, as evidenced by the U.S. situation in 2022 when inflation reached 9.1%, leading to legislative actions like the Inflation Reduction Act.
Countries experiencing high and variable rates of inflation may employ indexing of wage levels and interest rates to inflation to maintain purchasing power. Nonetheless, such volatility is often politically untenable in high-income economies, which favor maintaining low and stable inflation rates to achieve broad economic goals such as stable prices, full employment, and economic growth.
