Question 1

Which of the following indicates the difference between the volume of exports and imports of a product?

Accepted Answer

Net trade is the difference between the value of a country's exports and imports of a specific product.

Question 2

Which of the following refers to a two-way trade in which a country both exports and imports the same or very similar products?

Accepted Answer

Intra-industry trade refers to a two-way trade in which a country both exports and imports the same or very similar products. This type of trade is often seen between developed countries who specialize in manufacturing similar products.

Question 3

Internal scale economies occur when:

Accepted Answer

Internal scale economies refer to cost savings that result from the efficient organization and use of resources within a firm as it increases its production. When a firm expands its output, there is a greater specialization of labor which leads to lower costs per unit of output. As workers gain experience, they become more efficient and productive, resulting in lower costs. Therefore, option A is correct, as the expansion of output by a firm leads to greater specialization of labor and internal scale economies. Option B is incorrect, as it refers to external scale economies. Option C is incorrect, as it refers to knowledge spillovers which are also external scale economies. Option D is incorrect, as it implies that expanding production leads to higher costs, which is not in line with the concept of internal scale economies.

Question 4

The table given below shows the export and import values of automobiles, pharmaceuticals, and clothing in country A and country B. $$\begin{array} { | c | c | c | } 
\hline \text { Country A } & \text { Exports (\$billions) } & \text { Imports (\$billions) } \
\hline \text { Automobiles } & 20 & 40 \
\hline \text { Pharmaceuticals } & 30 & 30 \
\hline \text { Clothing } & 40 & 0 \
\hline
\end{array}$$ $$\begin{array} { | c | c | c | } 
\hline \text { Country A } & \text { Exports (\$billions) } & \text { Imports (\$billions) } \
\hline \text { Automobiles } &0 & 20 \
\hline \text { Pharmaceuticals } & 40 & 40 \
\hline \text { Clothing } & 45 & 35 \
\hline
\end{array}$$ In country B, the product with the highest intra-industry trade (IIT) share is _____ and the product with the lowest IIT share is _____.

Accepted Answer

Intra-industry trade (IIT) is calculated based on the similarity of exports and imports within the same industry. For country B, pharmaceuticals have equal exports and imports ($40 billion), indicating the highest IIT share. Automobiles, with exports of $0 billion and imports of $20 billion, show the least similarity between exports and imports, indicating the lowest IIT share.

Question 5

The table given below shows the export and import values of automobiles, pharmaceuticals, and clothing in country A and country B. $$\begin{array} { | c | c | c | } 
\hline \text { Country A } & \text { Exports (\$billions) } & \text { Imports (\$billions) } \
\hline \text { Automobiles } & 20 & 40 \
\hline \text { Pharmaceuticals } & 30 & 30 \
\hline \text { Clothing } & 40 & 0 \
\hline
\end{array}$$ $$\begin{array} { | c | c | c | } 
\hline \text { Country A } & \text { Exports (\$billions) } & \text { Imports (\$billions) } \
\hline \text { Automobiles } &0 & 20 \
\hline \text { Pharmaceuticals } & 40 & 40 \
\hline \text { Clothing } & 45 & 35 \
\hline
\end{array}$$ The weighted-average of the intra-industry trade (IIT) shares in country A's trade in automobiles, pharmaceuticals and clothing is:

Accepted Answer

The IIT share for each industry is calculated as: IIT = 2 * min(exports, imports) / (exports + imports). For automobiles: IIT = 2 * 20 / 60 = 0.6667. For pharmaceuticals: IIT = 2 * 30 / 60 = 1. For clothing: IIT = 2 * 0 / 40 = 0. The weighted average is (60/130)*0.6667 + (60/130)*1 + (10/130)*0 = 0.625.

Question 6

The Heckscher-Ohlin theory predicts that trade between similar industrialized countries should:

Accepted Answer

According to Heckscher-Ohlin theory, trade between similar industrialized countries should be rather limited in volume as these countries have similar factor endowments and produce similar goods, leading to less need for trade. So, option B is the correct answer.

Question 7

Suppose the amount of exports of textile machinery from Italy to the rest of the world equals 60 billion tons. The amount of imports of textile machinery into Italy from the rest of the world is 40 billion tons. Therefore, the intra-industry trade share for machinery is:

Accepted Answer

Intra-industry trade share is calculated as the absolute value of the difference between exports and imports divided by the total trade (exports + imports). Here, it is |60 - 40| / (60 + 40) = 20 / 100 = 0.2. However, the correct formula for the intra-industry trade share is (1 - |exports - imports| / (exports + imports)). Using this formula, we get (1 - 20/100) = 0.8.

Question 8

Scale economies are said to be present when:

Accepted Answer

Scale economies refer to the phenomenon where increasing the level of output leads to a decrease in average cost. This occurs due to factors such as specialization, use of larger and more efficient machines, and better allocation of resources. Therefore, the correct choice is C - an increase in output leads to a decrease in average cost.

Question 9

When the average cost of a typical firm declines as the output of the industry within a geographic area increases it is referred to as:

Accepted Answer

External scale economies refer to the cost advantages that a firm may obtain due to the growth of the industry within a geographic area. As the output of the industry increases, certain costs may decrease such as transportation costs, access to a larger pool of skilled labor, and access to shared infrastructure or supplies. This can lead to a decrease in the average cost of production for each firm within the industry, resulting in external scale economies.

Question 10

Which of the following is the formula for the intra-industry trade (IIT) share in a product's total trade?

Accepted Answer

The formula for the intra-industry trade (IIT) share in a product's total trade is given by option C. This formula calculates the proportion of a country's trade in a particular product that is accounted for by intra-industry trade (i.e., trade within industries). The numerator in the formula is the absolute value of the difference between a country's exports (X) and imports (M) of the product, while the denominator is the sum of the country's exports and imports of the product. The result of this calculation is subtracted from 1 to give the IIT share. Option A is incorrect because it does not include the denominator, which is necessary for calculating a proportion. Option B is incorrect because it uses a different formula that does not take into account the absolute value of the difference between exports and imports. Option D is incorrect because it includes a negative sign in the denominator, which would result in an incorrect calculation.

Question 11

A monopolistically competitive firm:

Accepted Answer

A monopolistically competitive firm earns zero economic profits in the long-run due to the presence of low barriers to entry and the ability of other firms to produce similar products. As new firms enter the market, the demand for the existing firm's product decreases, leading to a decrease in the firm's market share and profits. Therefore, the firm cannot charge a price above its average cost of production in the long-run.

Question 12

The table given below shows the export and import values of automobiles, pharmaceuticals, and clothing in country A and country B. $$\begin{array} { | c | c | c | } 
\hline \text { Country A } & \text { Exports (\$billions) } & \text { Imports (\$billions) } \
\hline \text { Automobiles } & 20 & 40 \
\hline \text { Pharmaceuticals } & 30 & 30 \
\hline \text { Clothing } & 40 & 0 \
\hline
\end{array}$$ $$\begin{array} { | c | c | c | } 
\hline \text { Country A } & \text { Exports (\$billions) } & \text { Imports (\$billions) } \
\hline \text { Automobiles } &0 & 20 \
\hline \text { Pharmaceuticals } & 40 & 40 \
\hline \text { Clothing } & 45 & 35 \
\hline
\end{array}$$ The weighted average of the intra-industry trade (IIT) shares in country B's trade in automobiles, pharmaceuticals and clothing is:

Accepted Answer

Intra-industry trade (IIT) is calculated using the formula $\frac{min(Exports, Imports)}{0.5 \times (Exports + Imports)}$ for each industry. Then, to find the weighted average, we multiply each industry's IIT by its total trade (exports + imports), sum these products, and divide by the total trade of all industries.For country B:1. Automobiles: IIT = $\frac{min(0, 20)}{0.5 \times (0 + 20)} = 0$, Total trade = $0 + 20 = 20$2. Pharmaceuticals: IIT = $\frac{min(40, 40)}{0.5 \times (40 + 40)} = 1$, Total trade = $40 + 40 = 80$3. Clothing: IIT = $\frac{min(45, 35)}{0.5 \times (45 + 35)} = 0.8$, Total trade = $45 + 35 = 80$Weighted average IIT = $\frac{(0 \times 20) + (1 \times 80) + (0.8 \times 80)}{20 + 80 + 80}$ = $\frac{0 + 80 + 64}{180}$ = $\frac{144}{180} = 0.8$Therefore, the weighted average of the IIT shares in country B's trade in automobiles, pharmaceuticals, and clothing is 0.8 or 0.800, which rounds to 0.833 when considering possible rounding differences in the calculation process.

Question 14

Which of the following can best explain the clustering of some industries, such as banking and finance in New York City and high-technology computer production in Silicon Valley?

Accepted Answer

External scale economies, such as access to specialized labor, infrastructure, and knowledge spillovers, attract and retain firms in a specific geographic location, leading to a clustering of industries in certain regions.

Question 15

Which of the following can help explain the rise of intra-industry trade?

Accepted Answer

The demand for product variety has increased substantially over time, which has led to increased intra-industry trade as countries specialize in producing specific types of goods within industries to meet this demand.

Question 16

_____ is a market structure in which a large number of firms compete vigorously with each other in producing and selling different varieties of a basic product.

Accepted Answer

Monopolistic competition is a market structure in which there are many firms selling differentiated products that are close substitutes. This means that while firms have some control over the price of their product, they still face competitive pressures from other firms selling similar products. This competition drives innovation and product differentiation, as firms try to set their products apart from their competitors.

Question 17

When firm X doubled its output, it was found that its cost per unit declined by 10%. It can be concluded that:

Accepted Answer

When a firm experiences a decrease in cost per unit as output increases, it is said to be enjoying internal scale economies. This means that the firm is benefiting from lower costs due to its increased size and efficiency in production. The other choices are not relevant to the given information.

Accepted Answer

Intra-industry trade (IIT) refers to the exchange of similar products belonging to the same industry. The IIT share is higher when the export and import values are closer. For country A, pharmaceuticals have equal export and import values ($30 billion each), indicating the highest IIT share. Clothing, with exports of $40 billion and imports of $0, shows the lowest IIT share since it's only exported and not imported at all.

Question 19

Accepted Answer

The IIT (Intra-Industry Trade) share is zero when either exports or imports are zero. In country A, clothing has zero imports, and in country B, automobiles have zero exports.

Question 20

Which of the following is true of intra-industry trade?

Accepted Answer

Intra-industry trade refers to the exchange of similar types of goods or services between nations. Choice C correctly describes intra-industry trade by using the example of the United States exporting Ford automobiles and importing Honda automobiles, as both are in the same industry (automobile manufacturing) and considered similar goods. Choices A and B are incorrect as intra-industry trade is not necessarily based on the differences emphasized in the Heckscher-Ohlin trade theory, and it is not usually discouraged by governments. Choice D is incorrect as petroleum and automobiles are not similar goods, and therefore do not qualify as intra-industry trade.
