----------------- HES POSTING ----------------- Jevons' The Theory of Political Economy, ch. (5?) on Labor, definitely describes labor supply as determined by the calculus of pain and pleasure, but I don't recall leisure being explicitly discussed. It was more the pain (disutility) of labor vs. the benefits to be had as a result of labor. Non-labor is implicitly an absence or avoidance of pain associated with labor.
