1:What is GDP deflator and how does it differ from the consumer price index
2:discuss the three approaches of measuaring national income? and show that approaches gives indentical result.

what are the difference between GDP and GNP and which is the better measure of income and .why?

The demand function for product X is: Qd = 600 – 20Px + 0.02Y – 5Pr
The supply function is: Qs = –300 + 10Px
Where:
Qd = the quantity of X demanded
Qs = the quantity of X supplied
Px = the price of product X
Y = the average consumer income
Pr = the price of the related product R

Is product X a normal or an inferior good? Explain. (3)
1.2 Are products X and R substitutes or complements? Explain. (3)
1.3 If Y = R35 000 and Pr = R20, draw the precise demand curve for product X. (8)

1.5 In the labour market for carpenters, the current market clearing wage rate is R800 per day. With the aid of a diagram, discuss the welfare effects of government intervention in the form of legislation that sets the minimum wage rate for a carpenter at R1000 per day. (20 marks)

Consider a Cournot duopoly with the following inverse demand function:p(Q) =a−Q where p is the price of the product and Q is the total amount of goods exchanged in the market. The total costs areC(q1) = 300q1, C(q2) = 300q2 for firm 1 and firm 2, respectively. But the demand is uncertain (i.e., a new product may be introduced soon which will decrease the demand drastically). Firm 1 learns whether demand will be high (a =1800) or small (a=900) before it makes its quantity decision. However, firm 2 knows just the probability of high demand (1/4) and the probability of low demand (3/4). All of this is common knowledge. In particular, firm 2 knows that firm 1 knows the demand for certain. The two firms simultaneously choose quantity. What is the Bayesian equilibrium of the game (price in both states of the world and quantity produced by each firm)?

1.1 Construct a production possibility frontier to illustrate Tom’s earnings potential between the two
careers if initially he was not working as a carpenter, then he worked one week per month, then two,
then three and finally four weeks per month (assuming only four weeks in a month). Please include a graph

Tom is a full-time lecturer at a private higher education institution and is considering a career in carpentry. He wishes to pursue a career in carpentry (a childhood dream) which he has studied part-time and is now equipped to take on clients. In his current position he earns a rate of R1000 per day and if he were to pursue a career in carpentry he would earn R800 per day. Due to the flexibility of the employment conditions at the higher education institution he works for, Tom can negotiate the number of days he works at and will receive a rate of remuneration based on the number of days worked.
