In the Correspondence of the Journal of Economic Perspectives 11(2), 
Spring 1997, pp. 190-1, Erich Kaufer comments on Persky's article and 
claims to have found an earlier economic use of the phrase ceteris 
paribus. According to Kaufer this first use was made by Petrus Olivi (ca. 
1248-1298) in ca. 1280. In his tractate De emptionibus et venditionibus, 
de usuris, de restitutionibus, Petrus Olivi states that goods produced 
with greater labor and at greater risk realize - ceteris paribus - a 
higher price.
