When inflation may be good news

Japan has suffered from deflation on and off for more than 20 years. A problem with falling prices is that they discourage spending as people wait for prices to fall further. One of the three elements of the Japanese government’s macroeconomic policy (see Japan’s three arrows) has been expansionary monetary policy, including aggressive quantitative easing. A key aim of this is to achieve an inflation target of 2% and, hopefully, propel the economy out of its deflationary trap.

The latest news, therefore, from Japan would seem to be good: consumer prices rose 0.4% in June – the first rise for more than a year. But while some analysts see the rise in prices to be partly the result of a recovery in demand (i.e. demand-pull inflation), others claim that the inflation is largely of the cost-push variety as the weaker yen has increased the price of imported fuel and food.

If Japanese recovery is to be sustained and broadly based, a growth in real wages should be a core component. As it is, real wages are not growing. This could seriously constrain the recovery. For real wages to grow, employers need to be convinced that economic recovery will be sustained and that it would be profitable to take on more labour.

The success of the expansionary policy, therefore, depends in large part on its effect on expectations. Do people believe that prices will continue to rise? Do employers believe that the economy will continue to expand? And do people believe that their real wages will rise?

  1. Distinguish between cost-push and demand-pull inflation? Do higher prices resulting from a depreciation of the currency always imply that the resulting inflation is of the cost-push variety?
  2. In the Japanese context, is inflation wholly desirable or are there any undesirable consequences?
  3. Consider whether a two-year time frame is realistic for the the Bank of Japan to achieve its 2% inflation target.
  4. What is meant by the output gap? Using sources such as the European Commission’s European Economy, AMECO database and the OECD’s Economic Outlook: Statistical Annex Tables (see sites 6 and 7 in the Economics Network’s links to Economic Data freely available online) trace the Japanese output gap over the past 10 years and comment on your findings.
  5. What supply-side constraints are likely to limit the rate and extent of recovery in Japan? What is the Japanese government doing about this (see the third arrow of Japan’s three arrows)?
