I. Introduction Skill-biased technological change (SBTC) has been a leading explanation for the rise in wage inequality almost since economists first noticed the increase in wage inequality that began at the end of the 1970s. A recent wave of research, however, has questioned important aspects of the standard version of SBTC models of wage inequality (Autor, Levy, Murnane, 2003; Autor, Katz, and Kearney, 2006, 2008; Acemoglu and Autor, 2011, 2012; and others), frequently invoking arguments made in an earlier round of criticism of SBTC-based explanations (Mishel and Bernstein, 1994, 1998; Howell, 1994, 1999; Mishel, Bernstein, and Schmitt, 1997; Howell and Wieler, 1998; Card and DiNardo, 2002, 2006). The new research rejects key features of the long-standing SBTC models, but is itself closely tied to an alternative, technology-based explanation of rising wage inequality.
