(Units 1-5)

Q. 1 Describe the rules of integration with examples. (20)

  • Q. 2 Let the demand and supply functions be as follows; (20)
  • , ,
  • Assuming that the market is cleared at every point of time, find the time path p(t) (general solution)
  • (b) Does this market have a dynamically stable intertemporal equilibrium price?
  • (c) Assumption of the present model that Qd = Qs for all t is identical to that of the static market model. Nevertheless, we still have a dynamic model here.
  • How come? (20)
  • Q. 3 Find the general solution of the equation; (20) ; Where we have
  • U=2t, w=t, and (k arbitrary)
  • Q. 4 Solve the complementary function of the equation, where: (20)

    Q. 5 On the basis of demand and supply for the Cobweb model as follows, find the intertemporal equilibrium price and determine whether the equilibrium is stable. (20)
