Smith recognizes the role of bargaining by the workers as an important determinant of real wages (Aspromourgos, 2010, p. 1173; Stirati, 1994, p. 51; WN, p. 85). Thus, there is a central role for history and institutions to determine real wages (see Aspromourgos, 2009, pp. 248–249). Smith is also open to the possibility of workers’ wages rising significantly above customary subsistence such that it enables them to engage in “conveniences” consumption—especially when the economy is growing. This rise in wages, for Smith, occurs through strengthening of workers’ bargaining power (Aspromourgos, 2010, p. 1179). Smith believes that competition generates innovation which causes productivity growth and subsequently perhaps higher real wages (Aspromourgos, 2009, p. 208).
