Misuse of the Nobel name
Some critics argue that the prestige of the Prize in Economic Sciences derives in part from its association with the Nobel Prizes, an association that has often been a source of controversy. Among them is the Swedish human rights lawyer Peter Nobel, a great-grandnephew of Alfred Nobel.[38]
Nobel accuses the awarding institution of misusing his family's name, and states that no member of the Nobel family has ever had the intention of establishing a prize in economics.[39] He explained that "Nobel despised people who cared more about profits than society's well-being", saying that "There is nothing to indicate that he would have wanted such a prize", and that the association with the Nobel prizes is "a PR coup by economists to improve their reputation".[38]
Accusations of bias
Critics cite the apparent snub of Joan Robinson as evidence of the committee's bias towards mainstream economics.[40][41]
Undue authority
In his speech at the 1974 Nobel Prize banquet, Friedrich Hayek stated that had he been consulted on the establishment of a Nobel Prize in economics, he would have "decidedly advised against it",[34][42] primarily because "The Nobel Prize confers on an individual an authority which in economics no man ought to possess. This does not matter in the natural sciences. Here the influence exercised by an individual is chiefly an influence on his fellow experts; and they will soon cut him down to size if he exceeds his competence. But the influence of the economist that mainly matters is an influence over laymen: politicians, journalists, civil servants and the public generally."[42] Nevertheless, Hayek accepted the award.
