The authors make three points in this reply to the article by Allegretto, Dube, Reich, and Zipperer (ADRZ 2017). First, ADRZ shed no new light on the sensitivity of estimated minimum wage employment effects to the treatment of trends in state-level panel data, and they make some arguments in this context that are misleading or simply wrong. Second, the key issue ADRZ emphasize—using “close controls” to account for shocks that are correlated with minimum wage changes—does not generate large differences in findings, and ADRZ do not address evidence from Neumark, Salas, and Wascher (NSW 2014a) that questions the validity of the close controls used in Allegretto, Dube, and Reich’s (ADR 2011) and Dube, Lester, and Reich’s (DLR 2010) work. Third, ADRZ ignore or dismiss a growing number of studies that address in various ways the same issue of potential correlations between minimum wages and shocks to low-skill labor markets that ADRZ argue generate spurious evidence of disemployment effects, yet often find rather large negative effects of minimum wages on low-skilled employment.
