Superstar economics, which has been used to explain the astonishing fees of top lawyers and the skyrocketing pay of star chief executives, dates back to the insight in the late 19th century of the British economist Alfred Marshall, who observed that "the relative fall in the incomes to be earned by moderate ability ... is accentuated by the rise in those that are obtained by many men of extraordinary ability."
