Abstract in English:
The real incomes of about two-thirds of households in 25 advanced economies were flat or fell between 2005 and 2014. Without action, this phenomenon could have corrosive economic and social consequences.
Most people growing up in advanced economies since World War II have been able to assume they will be better off than their parents. For much of the time, that assumption has proved correct: except for a brief hiatus in the 1970s, buoyant global economic and employment growth over the past 70 years saw all households experience rising incomes, both before and after taxes and transfers. As recently as between 1993 and 2005, all but 2 percent of households in 25 advanced economies saw real incomes rise.
Yet this overwhelmingly positive income trend has ended. A new McKinsey Global Institute report, Poorer than their parents? Flat or falling incomes in advanced economies, finds that between 2005 and 2014, real incomes in those same advanced economies were flat or fell for 65 to 70 percent of households, or more than 540 million people (exhibit). And while government transfers and lower tax rates mitigated some of the impact, up to a quarter of all households still saw disposable income stall or fall in that decade.
