Inflation Targeting

Inflation targeting is the central-bank practice of publicly committing to a numeric inflation goal so that policy, businesses, workers, and markets can coordinate expectations. Our mission: Find the world’s best economic ideas (Summer School World Tour) introduces it through New Zealand / 新西兰, where Arthur Grimes proposed a 0% to 2% target by 1992 and Don Brash implemented the painful disinflation.

The episode’s key point is that the target was not only a number. It worked as a credibility device: if the Reserve Bank of New Zealand could make low inflation believable, then businesses and workers might behave in ways that helped create low inflation. That places the concept next to Multiple Equilibria, Central Bank Independence, and Inflation Bias.

Key Claims

  • A target converts vague anti-inflation intent into a public benchmark.
  • Credibility and transparency matter because expectations can shape actual price-setting behavior.
  • The transition can be costly: New Zealand reached the target ahead of schedule, but unemployment rose above 11%.
  • Later adoption by the Federal Reserve, the United Kingdom, and Australia shows how a small-country experiment became a mainstream monetary-policy framework.
