The Benefits of Inflation
Summary:
In a series of speeches defending his record, Alan Greenspan reiterated the central banking orthodoxy, emphasizing his role in maintaining price stability and monetary balance. However, the often overlooked benefits of inflation deserve attention.Understanding Inflation's Role:
Alan Greenspan, previously seen as a key figure in the new economy, emphasized that his main task was to control prices and maintain financial stability. He avoided discussing the potential economic disruptions from asset bubbles or the impact of his own policies.Focusing solely on price stability can lead to deflation, a more dangerous economic challenge than inflation. Deflation, combined with negative savings and high debt, may result in prolonged economic stagnation. In contrast, the positive aspects of inflation are frequently ignored during global efforts to control fiscal and monetary expansion.
Inflation and Economic Growth:
Economists often state that inflation is not a guaranteed result of growth. It indicates the gap between actual and potential GDP. As long as the gap is negative, inflation remains low. Growth, in some cases, can even correlate with deflation.The subdued inflation in the U.S. and other countries may owe more to economic overcapacity than to central bank policies. Decades of inflation shifted investment strategies, and overcapacity, along with increasing competition, globalization, and deregulation, contributed to price wars and falling prices. According to Dresdner Kleinwort Wasserstein, the United States was experiencing deflation, with the non-financial business sector's price deflator at -0.6 percent annually by mid-2002. Germany faced similar challenges.
This situation can form a cycle, where consumer expectations of falling prices lower inflationary expectations and inflation itself. Central bank interventions may accelerate this process, threatening to turn benign disinflation into harmful deflation.
Inflation's Misunderstood Perceptions:
Inflation is often criticized for distorting economic signals, leading to confusion and misallocation of resources. People may struggle to determine whether price increases reflect true demand, speculation, or inflation, leading to poor decisions, such as delaying or over-investing.However, economist James Tobin likened inflation to "the grease on the wheels of the economy." Desired inflation rates vary: the European Central Bank targets 2 percent, while others, like the Bank of England, aim for a range between 1.5 and 2.5 percent. The U.S. Federal Reserve has tolerated rates between 3-4 percent.
These differences reveal broader disagreements about the role and management of inflation. Central banks typically fear inflation while neglecting deflation risk. As inflation decreases, disinflation can usher in deflation, altering consumer habits and leading to recessions.
Measuring Inflation Accurately:
Traditional inflation measures often miss critical economic realities. As noted by the Boskin Commission in 1996, innovative technologies can change products (and their prices) without being accurately reflected in pricing indices. For instance, cell phones weren't included in the U.S. consumer basket until 1998, possibly overstating inflation by a full percentage point annually.Current methods fail to consider key price categories, like securities and wages. Even including these, modern inflation definitions would remain inaccurate. In deflation, stagnant wages or zero interest rates can still impact inflation positively or negatively, but these nuances are not factored into today’s measurements.
Practical Effects of Inflation:
Inflation allows for wage flexibility. Workers might accept a small wage increase in an economy with 3 percent inflation but resist wage cuts with zero inflation, illustrating the "money illusion." This illusion is diminished when pay is performance-based. For instance, Japanese wages fell 5.6 percent over a year due to deflation and cuts in bonuses.Low inflation can reduce employment. At zero inflation, unemployment in the U.S. could rise by 2.6 percentage points. However, this can be countered by increased productivity, as seen in the U.S. during the 1990s.
Inflation as a Tool:
Low inflation or deflation leads to a "liquidity trap," limiting the ability to reduce interest rates to stimulate the economy, a problem Japan and, more recently, the U.S. have faced. Inflation can help manage trade and budget deficits by devaluing the local currency, boosting exports.Inflation’s fiscal effects include taxing nominal gains, which increases government revenues while reducing the real value of debts and expenditures. Thus, inflation can act as a non-recessionary fiscal correction.
Despite the short-term benefits, sustained inflation is unsustainable long-term. Nevertheless, it can be a useful counter-cyclical tool, moderating economic shocks and stabilizing systems. Inflation benefits borrowers by boosting earnings while eroding debt values, promoting consumption and investment.
Conclusion:
The connection between inflation and economic bubbles is complex, but low or volatile inflation can drive speculative behavior. Central banks’ inflation targeting aims to stabilize expectations with consistent policies, balancing the risks of both inflation and deflation.You can find the original non-AI version of this article here: The Merits of Inflation.
