“…In a series of influential studies, Galenson (2000Galenson ( , 2001Galenson ( , 2009) and Weinberg (2000, 2001) estimate hedonic age-valuation profiles for different cohorts of artists and find that in both the French and American cases, the younger cohort, that is, the cohort for which artistic innovation is more highly valued, has an agevaluation profile that ''peaks'' much earlier in life, consistent with the idea that the aptitudes to excel in this way are relatively stronger among younger people. This latter hypothesis has stimulated a number of subsequent studies of painters' careers, including Ginsburgh and Weyers (2006), who consider selected Old Master painters, Accominotti (2009) and Hellmanzik (2009Hellmanzik ( , 2010, who consider modern artists, and Hodgson (2011) and Galbraith and Hodgson (2012), who study a sample of Canadian artists. Overall, the results are rather mixed, and the hypothesis has been criticized by many.…”
