“…Other channels of adjustment that have been explored in the minimum wage literature include changes in hourswhere the empirical evidence is mixed (see Neumark and Washer, 2008, p. 78), job amenities (see Simon and Kaestner, 2004), prices (see Aaronson, 2001;Aaronson, French, and MacDonald, 2008;Lemos, 2008;and MaCurdy, 2015), and compression of wage differentials (see DiNardo, Fortin, and Lemieux, 1996;and Autor, Manning, and Smith, 2016). 4 In a recent paper, Basker et al (2017) explore a different kind of substitution of technology for labor (at least, the firm"s labor) that can occur in response to a higher minimum wagenamely, substitution of a customer"s labor for a worker"s labor (in, e.g., a self-service gas station, or using a bank ATM). They suggest that this kind substitution may occur when low-skilled labor becomes expensive and technology enables labor replacement in tasks that are not easy to automate.…”
