70. Which is the following in not true about the fixcd accelerator modcl? (1) The capital-output ratio is assumed to be constant (2) Complete absence of excess capacity is assumed (3) The lagged capital-output relations in this case is given as I, =® (Y1-Y,-2) (4) The capital goods industries have surplus capacity (31 -3AICA T H I = B (Y- - Y-2) 71. With different values of a (propensity to consume) and p faccelerator coeficient), Samuelson in his theory of business cycles claimed that there will be explosive 71. cycles for the following values of a and B (1) a = 0.5 and B = 0 (2) a = 0.6 and ß =2 (3) a = 0 5 and ß =1 (4) a = 0 8 and B = 4
