The persistent inflation in the United States is an ongoing concern for policymakers and researchers alike, a problem that has historical precedents going back to the era of renowned economist John Maynard Keynes in the 1930s. A recent analysis, employing a series of regression analyses on U.S. core Consumer Price Index (CPI) inflation data (excluding food and energy), has shed light on the duration of inflation persistence. Through this analysis, it was revealed that inflation persistence, characterized by significant lags in the autocorrelation of inflation rates, suggests that the effects of inflation could extend for nearly a year, indicating a troubling inflation persistence that challenges traditional economic models.
Historically, economic models have tried to explain inflation through various perspectives, primarily focusing on market imperfections in the labor or goods markets and whether these markets clear effectively. The four traditional models identified include the worker-misperception model, the imperfect-information model, the sticky-wage model, and the sticky-price model, each offering insights into why prices and wages may not adjust efficiently in response to economic changes. These models, however, seem less applicable in today’s digital and data-driven economy, where market imperfections are significantly reduced, and the assumption of markets not clearing is not widely adopted. Despite advances in technology that allow for rapid price adjustments, wages tend to be less flexible, leading to the notion that wage stickiness could be a primary driver of price stickiness – a concept that modern economic models tend to support.
The wage-price spiral hypothesis plays a crucial role in understanding the dynamic between wages, prices, and inflation. This hypothesis posits that a cyclical process wherein wage increases lead to higher prices, which in turn lead to further wage increases, thus perpetuating the cycle of inflation. This relationship is closely tied to the Phillips curve framework, which suggests an inverse relationship between unemployment and inflation. When examining the data, there’s a clear uptrend in both wages and service sector prices since 2010, indicating a longstanding inflation pressure that corresponds with the wage-price spiral hypothesis. A comparison of hourly earnings growth and services inflation reveals that inflation in services remains high at 5.2 percent, with both earnings and service prices moving in tandem since the mid-1990s. This co-movement suggests that inflation expectations are currently well-anchored, contrasting with the 1980s when price growth significantly outpaced wage increases due to uncontrolled inflation expectations.
As the U.S. economy moves past the high base period, it is expected that observed inflation, particularly in the coming months, will register higher than in recent times. With earnings inflation slowing to 4 percent, it is anticipated that services inflation, and consequently overall inflation, will maintain a similar level in the foreseeable future. This underscores the persistent challenge of addressing inflation in an economy where wage and price adjustments are not perfectly synchronized, shedding light on the complexities of modern economic policymaking in the face of entrenched inflationary pressures.
