"The COLA is making a comeback.
Higher prices, a worker shortage and a revitalized labor movement are bringing about the return of pay increases tied to inflation, known as cost-of-living adjustments, or COLAs.
On Tuesday, striking workers at food maker Kellogg Co. ratified a contract that included a COLA, the second major labor agreement in recent weeks to feature such pay adjustments. Analysts say COLAs could spread in future negotiations between employers and unions.
Under a COLA, a worker’s pay rises to compensate for the increase in consumer prices. The idea is to protect wages in times when consumer prices are rising rapidly and unpredictably.
The provisions were often part of union contracts 40 or 50 years ago when inflation was high. Starting in the 1990s, as inflation slowed to more modest levels, COLAs became less prominent.
"“COLAs exist not primarily because inflation is higher, it’s because there’s uncertainty about inflation,” he said [Harry Katz, an economist at Cornell University]. The provision “provides a way of basically sharing the risk.”"
"COLAs could also themselves contribute to inflation. Raising wages to compensate for higher prices could lead to a situation in which companies raise prices to recoup higher wages, which causes workers to ask for yet higher wages, causing the two to feed off each other."
"Such a wage-price spiral emerged in the 1970s and was broken only by tighter monetary policy, Mr. Walden said [Michael Walden, professor emeritus at North Carolina State University]."

"A shrunken labor force, combined with a strong demand for labor, has given workers greater bargaining power. That could prompt more unions to ask for COLAs."
