Profit-laden companies are resisting bigger wage hikes

Quick take: Economists have struggling to grasp why companies are not feeling forced to pass on bigger wages to attract and keep workers despite two years of steadily dropping joblessness, reaching 3.9% last month, the lowest since 2000.

But an increasing consensus is this simple conclusion — because they can.

• "As long as firms have the clout to hold back pay increases, they will," Jared Bernstein, chief economic adviser to Vice President Joe Biden during the Obama administration, told Axios today.

The background: In the 2000 plunge of joblessness, wages increased by 4% on average. Today, companies across industries and the country complain of an employee shortage, but on average raised wages by just 2.6% last month, maintaining a long period of relatively flat compensation, according to the U.S. Bureau of Labor Statistics. Among reasons that economists cite:

• A new underlying structure: Productivity growth is lower, people are more or less permanently out of the work force with drug addiction and criminal records, and unionization numbers are much smaller.
• Business trends: Companies are becoming more automated and industries more concentrated, says Martha Gimbel, research director at Indeed. "It may just be that these structural factors are making it more difficult for workers to benefit," she tells Axios.

But, but, but ... Mark Zandi, chief economist at Moody's Analytics, tells Axios that less-watched statistics show more accelerated wage increases. Zandi cites the Employment Cost Index, which shows a 2.9% wage increase last quarter.

• He predicts that the number will rise to 3.5% by this time next year and closer to 4% by the end of 2019.
• "It's accelerating and is consistent with the state of the labor market," Zandi said.
