Francis Ysidro Edgeworth  (1845-1926)

Economista irlandés. Estudió Lenguas antiguas y modernas en el Trinity College de Dublín. Sabía alemán, español, francés e italiano. Posteriormente estudia leyes en Oxford. Parece ser que estudió matemáticas por su cuenta, sin atender clases formales. En 1880 está dando clases de lógica. Finalmente, en 1888, fue nombrado profesor de Economía Política en el King's College de Londres.

Casi todos sus escritos están dirigidos a economistas. Son ensayos sobre impuestos, los precios en el monopolio y el duopolio, teoría pura del comercio internacional y teoría de los números índice. Su obra "Psíquica Matemática" (1881) es una aplicación cuantitativa de la ética del utilitarismo a la vida económica. Su uso de las curvas de indiferencia fue aceptada muy lentamente y la del "núcleo" de una economía de intercambio solo ha conseguido atraer la atención muy recientemente como resultado de los desarrollos de la teoría de juegos. De hecho muchas de sus ideas están siendo redescubiertas en la actualidad.
