(a) Calculate the equilibrium levels of interest rate and capital funds in this economy. [5 points] (b) Draw the supply and demand curves in a diagram.
Calculate the values of consumer surplus, supplier surplus and economic surplus, and show them on the same diagram. [5 points] (c) The government of that economy is very keen on transforming the economy into an industrialized one by making more capital funds available for investment. Based on the belief that the current equilibrium interest rate is too high, it decides to impose an interest rate ceiling of 5%. Will it succeed in making more funds available for investment? Is the economic surplus under this case greater than that in case (b)? [5 points] (d) Discuss any other costs or benefits of the above interest rate ceiling policy.
Explain why the difference in the economic surplus between case (c) and (b) is likely to be an overestimation or underestimation of the actual gain or loss of the interest rate ceiling policy. [5 points] Question 2 [20 points] : E-commerce is predicted to reduce the cost of intermediary services such as those of travel agencies or investment advisors. Consider the market for air travel.
