In the present research, New-Keynesians’ Philips hybrid curve has been derived by using the pricing models and the assumption of price and wage rigidity. Fridman- Phelps Philips curve and New-Keynesian Philips curve are special types of New-Keynesian Hybrid Philips curves. The model used for rigidity of prices and wages in this article is pricing model of calov. Then, we have estimated this curve for Iranian economy for the time 1975-2007 by using GMM method.
