Answer #1

Given,

a) Derived the SRAS.

To Given, y = 7 + a(P-EP) Glhere, firms set their desired prices as : Pq = ptacy-fo Ps - EPtaley-87) Thus, The price firms, t.: Y = 200+0.5_ (P-EP). 0.500.5 .:7 = 200 + 2(P-EP) This is the show that the derivation of output from the natural rate is t= 0.75 0.25% 0.5 = 0.75 - 0.125 2 ? G1 . Here, SRAS=y=200+G(P-EP) Also, LRAS: Y=200 and P= Ep with AD : Ya looo-lop iP=&P=80

    Consider the economy of Freeland, whose overall actual price index and actual output are P and Y respectively, and the natural rate of output is Yˉ . There are two types of firms in Freeland: firms with flexible prices, which set prices according to p = P + 0.5(Y − Yˉ ); and firms with sticky prices, which set prices base on p = Pe (the expected overall price index). Also the fraction of firms with sticky prices is s...

Two firms sell horizontally differentiated products located at opposite ends of the one-dimensional product space. Firm O is located at 0. Firm 1 is located at 1. M consumers are uniformly distributed between 0 and 1, with each consumer's location giving his most preferred type of product. Each consumer places value v on one unit of his most preferred product, but incurs a transportation cost. AD...
