How SA central bank's MPC may use capital controls
A firm sells in two markets and has constant marginal costs of production equal to $2 per
unit. The demand and marginal revenue equations for two markets are as follows:
MARKET I MARKET II
P1 = 14 – 2Q1 PII = 10 – QII
MRI = 14 – 4QI MRII = 10 – 2QII
Using third-degree price discrimination, what are the profit maximizing prices and
quantities in each marker? Show that greater profits results from price discrimination than
would be obtained if a uniform price were used.
A. Find the equilibrium quantity of the following: (55,55; 52.5,80; 50,105; 47.5,130; 45,155)
B. Find the equilibrium price of the following: (55,55; 52.5,80; 50,105; 47.5,130; 45,155)
C. Find the graph of supply and demand and the market equilibrium of the following: (55,55; 52.5,80; 50,105; 47.5,130; 45,155)

A. Solve the following:
1. If the price increases from 30 to 40 and the quantity demanded falls from 50 to 30, what is the elasticity of demand?
2. If the price decreases from 20 to 10 and quantity demanded rises from 10 to 50 units, what is the elasticity of demand?
A. Solve the following:
Assuming that the demand function for Good X is Qd=60-P/2 and the supply function for Good X is Qs=5+5P. Find the supply and demand schedule and the graph of supply and demand and the market equilibrium.

For Good X: ?
For Supply Schedule of Good X: ?
Equilibrium quantity: ?
Equilibrium Price: ?

I borrowed 1000 today if i need to pay annually for 10 years how much will my payment be if interest is : 15% compounded bi-monthly during the 1st five ears and 12% compounded continuously during the next five years?
How has this looting of shops in south Africa have undermined the capitalistic economic system in the private ownership of the factors of production.
c) In order to improve the model, the two researchers added the variable T (time)
and obtained:
Yt = -0.740 + 0.578 It + 0.218 Dt + 46.6 Rt – 40.4 Tt
(1755) (0.442)
(0.959) (10.9) (26.9)
Standard error of estimates are in parenthesis
Adjusted R2 = 0.61
Given that irrigated area increased and dry land area decreased over the sample
period, give reasons why you could have expected the coefficient of It, Dt and Rt to
change the way they have.
