Today, for a given rate of GDP growth, the corresponding inflation rate is substantially higher than it was over the past two decades. In other words, inflation especially house price inflation has become an important constraint on growth.

The fear now in both countries is that inflation shocks could turn into a self reinforcing price spiral. As the IMF cautions, core inflation excluding commodities has risen from 2 to 3.75 , suggesting that inflation is broadening.

Consumer price inflation in the eurozone has been below target for 22 consecutive months long before the price of oil started collapsing. Cheaper oil is a boon for growth but it also lowers long term inflation expectations, which are the true target of monetary policy.

The consumer price index in July 2016 compared to June 2016 was 101.0 , i.e. the monthly inflation was 1.0 .

Falling oil prices and the prospect of a prolonged period of low inflation also seem to have affected inflation expectations. Given the potency of the recent oil price shock, the risk is that inflation may temporarily slip into negative territory in the coming months.

Modern central banking has worked wonders to bring down inflation. Ultimately, however, a central bank s anti inflation policies can work only within the context of a macroeconomic and political framework that is consistent with price stability.

In the run up to the crisis, the US Federal Reserve Board (an informal inflation targeter) was even more committed than the MPC to this orthodox view so committed, in fact, that it barely allocated any time or resources to analyzing house price fluctuations.

For inflation, the same is applied for updating previous assumptions based on the actual monthly consumer price indexes prevailing in the country of operation.

The Fed decided to define price stability as a two percent annual inflation over the medium term of the price index of consumer expenditures. For the past 12 months, that rate of increase has been about 1.5 .

Here, the Fed is making a fatal mistake, as it relies heavily on a timeworn inflation forecasting methodology that filters out the special factors driving the often volatile prices of goods like food and energy. The logic is that the price fluctuations will eventually subside, and headline price indicators will converge on the core rate of inflation.

Some policymakers have concluded from Phelps analysis that the unemployment rate cannot be lowered permanently without ever increasing levels of inflation. Thus, monetary authorities should simply focus on price stability by targeting the rate of unemployment at which inflation does not increase, referred to as the non accelerating inflation rate of unemployment (NAIRU).

First, it contributes to yen depreciation and dollar appreciation as carry traders switch out of yen. Second, it increases global asset demand, generating asset price inflation.

Moreover, energy and food price shocks can be both large and largely unpredictable, while the speed of price changes tends to increase with big shocks. Most forecasting models used by central banks therefore put a large weight on recent inflation.

BEIJING Fixated on inflation targeting in a world without inflation, central banks have lost their way. With benchmark interest rates stuck at the dreaded zero bound, monetary policy has been transformed from an agent of price stability into an engine of financial instability.

Chinese authorities are so worried by their country s 7 inflation they are copying India and imposing price controls on food. Even the United States had inflation at 4 last year, though the Federal Reserve is somehow convinced that most people won t notice.

In normal times, central banks want to reduce inflation. The problem is that pre announced hikes in tax rates or administered prices can have the undesirable effect of building annual price increases into public perceptions, undermining the central bank s inflation fighting efforts.

The inflation rate for various non staff objects of expenditure such as utilities, maintenance and supplies is based on forecasts of price index movements by the Austrian Institute for Economic Research, or on assumed inflation trends at the locations of field offices.

It all starts when some imbalance causes overall inflation or some key price typically the exchange rate, but also power, water, and gasoline to come under upward pressure. The government then uses its coercive power to keep a lid on price growth.

And it is failing today, leading the Fed consistently to overestimate underlying inflation. Indeed, with oil prices having plunged by 50 over the past year, the Fed stubbornly maintains that faster price growth and the precious inflation rate of 2 is just around the corner.

The potential changes to the scheme include shifting how the annual inflation based increase in benefits is measured from the retail price index to the lower consumer price index, as well as limiting future increases in pension payments to the minimum required by law.

But claims that China is overheating don t seem to be based on observations of inflation. While China s consumer price index rose 5.3 in the year ending in July 2004, this was due primarily to a spike in food prices both before and since, inflation has been negligible.

Administrative measures in the agricultural sector, aimed at alleviating supply bottlenecks for pork, cooking oil, fresh vegetables, and fertilizer, have pushed food price inflation lower. This is the main reason why the headline consumer inflation rate receded from 6.5 in July 2011 to 4.2 in November.

What little impact import price shocks have on US inflation is highly transitory, with most of the effect tapering off after just two quarters. A sharp 10 appreciation of the US dollar, for example, would reduce inflation for non fuel imports by 4.4 cumulatively over the next 2 3 quarters, but would have only a negligible impact on inflation after that point.

At least the existing 2 inflation target stands for something, because central bankers can portray it as the moral equivalent of zero. (Most experts believe that a true welfare based price index would show significantly lower inflation than government inflation statistics indicate, because official data fail to capture the benefits of the constant flow of new goods into the economy.)

Inflation.

The price stability mandate has been trumped by concerns about growth. The fear is that tightening monetary policy to bear down on inflation could snuff out the faltering economic recovery.

For inflation, previous assumptions are updated on the basis of actual monthly consumer price indices prevailing in the country of operation and any adjustments indicated by the respective field offices.

These economic adjustments could occur much more smoothly if the eurozone as a whole were to pursue a more expansionary policy. If the target inflation rate for the eurozone were to be set temporarily at, say 3.5 , and if the countries with current account surpluses encouraged domestic inflation rates somewhat above the eurozone s target, there could be real price adjustment within the eurozone without price deflation in the troubled countries.

Notably, price growth turned positive last month, suggesting that the threat of deflation has been eliminated. This has prompted a modest uptick in expected inflation the ECB s favorite measure of price stability not for the immediate future, but in five years, and then for five years.

At a time when inflation is already close to 2 or higher, depending on how it is measured, the real federal funds rate would be at zero at the end of 2015. Instead of ensuring price stability, monetary policy would be feeding a further increase in the inflation rate.

Because the ECB was given the sole task of achieving and maintaining price stability in the euro area, inflation rates seem the most logical starting point for comparison. In 1999, the difference between the euro zone countries with the lowest and highest inflation rate was two percentage points.

2. Price and price increases

In addition to tempering debt problems, a short burst of moderate inflation would reduce the real (inflation adjusted) value of residential real estate, making it easier for that market to stabilize. Absent significant inflation, nominal house prices probably need to fall another 15 in the US, and more in Spain, the UK, and many other countries.

It is time for central banks to accept this fact and adopt a comprehensive, long term monetary policy approach even if it means that, in the short term, consumer price inflation deviates from what is currently understood as price stability. Temporary fluctuations in a narrow and imprecisely measured CPI are a small price to pay to secure the long term stability of money.

These ideas, combined with effective policy practice like that of the US Federal Reserve under Paul Volcker s chairmanship, led many countries worldwide toward more explicit inflation targeting, in which central banks stabilize inflation expectations by making a credible commitment to a predetermined rate of price growth. By the 1990 s, inflation was old news in the advanced economies, with much of the developing world soon to follow.

Forget Inflation

Inflation adjustment

The discussion quickly turned to the difficulty of measuring inflation accurately and the need to build in a safety cushion to avoid deflation. According to Greenspan, Price stability is that state in which expected changes in the general price level do not effectively alter business and household decisions.

But if that were true, central banks around the world would have set it as a target long ago. Instead, all of them define price stability as low, stable, but positive inflation.

Inflation targeting means that a central bank puts the pursuit of price stability above all other objectives. This is what the ECB does and what the Fed s Alan Greenspan does not do.
