The Employment Cost Index (ECI) is a comprehensive measurement of labor costs and their growth rate. It is said to signal changes in wage inflation, so it's important for everyone to know about it!The ECI measures compensation costs incurred by employers, including wages, salaries, and employee benefits. It covers around 70% of civilian workers in the United States. The index is compiled monthly by the Bureau of Labor Statistics.Some economists consider the ECI to be one of the most important indicators of inflation. When labor costs grow faster than prices overall, that can lead to increased inflationary pressure. So watch out for big jumps in the ECI - they could mean trouble ahead for consumers!
