Did robots cause the decline of labor? Or was it China? Why has labor's share of income declined in advanced countries? (Noah Smith, 2/24/14, The Week)
Mike Elsby and his coauthors find support mostly for story number three. In their own words:U.S. data provide limited support for...explanations based on the substitution of capital for (unskilled) labor to exploit technical change embodied in new capital goods...[I]nstitutional explanations based on the decline in unionization also receive weak support...[W]e provide evidence that highlights the offshoring of the labor intensive component of the U.S. supply chain as a leading potential explanation of the decline in the U.S. labor share over the past 25 years. [emphasis mine] [The Decline of the U.S. Labor Share]This finding disagrees with some other recent papers, such as Karabarbounis and Neiman (2013), who support the "robots" story. Read Elsby et al. to see the particulars of the argument.
