• In the diagram AD is aggregate demand and AA is the import line.
• Import line AA is positively sloped showing that import increases with income.
• AA is flater than AD because as income increase some of the additional domestic demand falls on foreign goods
• Net exports are a decreasing function of income
• At ytb (‘tb’ stands for trade balance), the level of income at which the value of imports is equal to the value of exports.

Answer 18.
i. When marginal cost (MC) is above average cost (AC), the average cost rises, that is, the marginal cost (MC) pulls the average cost (AC) upwards.
ii. When marginal cost (MC) stands equal to the average cost (AC), the average cost remains the same, that is the marginal cost pulls the average cost horizontally.
iii. If the marginal cost (MC) is below the average cost (AC); average cost falls, that is, the marginal cost pulls the average cost downwards.

Answer 19.
National income identify for an open economy
In a closed economy, there are three sources I of demand for domestic goods – Consumption
I (C), government spending (G), and domestic investment (I).
We can write
Y = C + I + G
In an open economy, exports (X) constitute an additional source of demand for domestic goods and service that comes from abroad and therefore must be added to aggregate demand. Imports (M) supplement supplies in domestic markets and constitute that part of domestic demand that falls on foreign good and services. Therefore,the national Income identify for an open economy is
Y + M = C + I + G + X
Rearranging, we get
Y = C + I + G + X – M
or
Y = C + I + G + NX
Where, NX is net exports (exports – Imports).
A positive NX (with exports greater than imports) implies a trade surplus and a negative NX (with imports exceeding exports) implies a trade deficit.

Answer 20.
If the market of a particular commodity consists of more than one seller but the number of sellers is few, the market structure is termed oligopoly. The special case of oligopoly where there are exactly two sellers is termed duopoly. We shall explain the different ways in which the oligopoly firms may behave.
Firstly duopoly firms may collude together and decide not to compete with each other and maximize total profits of the two firms together. In such a case the two firms would behave like a single monopoly firm that has two different factories producing the commodity.
Secondly, take the case of duopoly where each of the two firms decide how much quantity to produce by maximizing its own profit assuming that the other firms would not change the quantity that it is supplying.We can examine the impact using a simple example where both the firms have zero cost.
Thirdly, some economists argue that oligopoly market structure makes the market price of the commodity rigid, i.e. the market price does not move freely in response to changes in demand

Answer 21.

Answer 22.
P = Rs 5 P1 = Rs. 20
P = P1 – P = 20 – 5 = 15
Q = 15 Units
Es = 0.5, Q = ? and Q1 = ?
\({ E }_{ S }=\frac { \Delta Q }{ \Delta P } \times \frac { P }{ Q } \)
0. 5 = 15/5 x 5/Q Or
0. 5 = 5/Q, 0.5 x Q = 5,
Q1 = 5/0.5 = 10
Q1 = Q + ∆Q
= 10 + 15 = 25
Initial output = 10 units
Final output level = 25 Units

Answer 23.

Answer 24.
The price of one currency in terms of the other is called the exchange rate. The exchange rate expressed in terms of money is called nominal exchange rate.

Where e is the one currency price of other currency (ie, nominal exchange rate) P and Pf price levels in two countries
Real exchange rate would be more relevant to buy domestic goods or foreign goods. It is because it protect the business partners from inflation in both the countries.

Answer 25.

Answer 26.

Answer 27.

Answer 28.
A. No, I do not agree with this statement completely because, there were no consequences if the government avoids the market interference of the outside agencies. However, today’s markets are beyond the controls of government. Therefore, the following adverse consequences on the consumers may happen
a. Each consumer has to stand in long ques to buy the goods from ration shops
b. Since all consumers will not be satisfied by the quantity of the goods that they get from the fair price shop, some of them will be willing to pay higher price for it. This may result in the creation of black market


B.a. In this case, many more firms will enter the market releasing that they can earn higher profit here than else where as a result, prevailing price there will be excess supply in the market. This excess supply will lower the market price and the market price will be equal to equilibrium price.
b. In the case many firms who are incurring losses will exit the industry. As a result at a prevailing prices, there will be excess demand will raise the market price will be equal to equilibrium price.

Answer 29.
Before implementing ERP we need to conduct a BPR to determine the changes in the structure of business process. This helps to an enterprise to avoid unnecessary modules in ERP. But all BPR may not lead to the implementation of new ERP.
