Equilibrium can be achieved at full employment and even at under employment situation. This equilibrium is also called effective demand point”. However, in order to be able to understand this principle, it is necessary first to know the concepts of … At that level APS will be negative .when the APS is negative APC will be greater than one. Ans: Equilibrium level of income S= I -10 + 0.2y = -3 + 0.1y 0.2y – 0.1y = -3 + 10 0.1y =7 y = 70, Components of equation c=20 + 0.90y explained in % mark question number 1, The schedule for consumption is as follows, C= 20 + 0.9 x 350 + 335 C= 20 + 0.9 x 400 = 380, Under short run fixed price, equilibrium output and equilibrium demand at fixed price and constant rate of interest can be found with the help of following formulas Y= “A, Thus, value of equilibrium output (y) depends on values of A (i.e, c + I) and b i.e AD = AS.
