3. This question explores IS and FX equilibria in a numerical example.
a. The consumption function is C = 1.5 + 0.8(Y - T). What is the marginal propensity to
consume (MPC)? What is the marginal propensity to save (MPS)?
b. The trade balance is TB = 5 [1-()] -
(0.2(Y-8). What is the marginal propensity to
consume foreign goods (MPCF)? What is the marginal propensity to consume home
goods(MPCH)?
c. The investment function is I = 3 - 10i. What is investment when the interest rate is equal
to 0.10=10%.
d. Assume government spending is G. Add up the four components of demand and write down
the expression for D. Make sure that you simplify the equation.
e. Derive the equation for the good market equilibrium using Y = D.
1. A firm has the following demand function: P = 60 – 0.5Q and its total cost is defined by TC= 13+ Qa. Find the maximum revenue b. Find the production to optimize the profit. c. Verify if the marginal revenue and marginal cost are the same at the profit-maximizing productionlevel. Exercise 6From the point of view of the firm, what decision criteria have been found relevant in the analysis ofproduction and profit? Provide two refernces with your answer.
5. Some people find options expensive and use more complex structures to reduce the cost. For
example, consider buying a call with a strike of $55 and selling a call with a strike of $60.
a. What is the cost of establishing this combined position?
b. What is the payoff of the combined position if the market price goes to $60?
c. What is the payoff of the combined position if the market price goes to $100?
