Abstract

Resumen: En este escrito se evalúa la consistencia teórica de la Curva de Phillips de Milton Friedman. Para esto se retoma la exposición de Friedman, destacando sus aportes al análisis de corto plazo del desempleo, los salarios y los precios, frente a la teoría de los clásicos y a la de Keynes. Se examina la hipótesis basada en la tasa natural de desempleo, revisando la utilización de los conceptos de desempleo involuntario, equilibrio macroeconómico e información imperfecta, así como los mecanismos de formación de expectativas de empresarios y trabajadores. Se concluye que su modelo es impreciso e incompleto y que su hipótesis se derrumba si la tasa natural de desempleo es endógena y cambia con los choques exógenos de demanda agregada.
