Although basic economic models postulate that the demand for a given product is a function of its price, this axiom does not hold true in all economic scenarios. Price elasticity of demand measures the extent to which demand changes when the price of a product rises or declines. Demand is termed very elastic if the price of a product greatly affects demand and very inelastic if the price does not affect demand at all.

As the number of possible substitutions for a product increases, demand for that product becomes more elastic. If the price of a product rises sharply and there are many similar options on the market, demand for the original product will sharply decrease as consumers purchase substitutions instead.

The broader the definition of a product, the more inelastic the demand for that product will be. The demand for cars in general is relatively inelastic; however, when cars are disaggregated into categories, a different picture emerges. The demand for some cars, such as sports cars and luxury vehicles, is inelastic while the demand for cars oriented towards the middle-class family market tends to be elastic.

Elasticity is also affected by the duration of price changes. When the price of a product rises, consumers often keep buying the product out of habit or convenience. As time elapses, consumers change their habits and product substitutions appear, causing demand to drop, increasing its elasticity.

A final determinant of elasticity is the product's necessity to the customer. Thus, products such a bread, water or medication, without which life would not be possible, are all extremely inelastic. On the other extreme, the demand for luxury items was very inelastic in Medieval Europe since nobles and royalty required these items to maintain their status in society.
Q1) What is the function of the first paragraph?

A)The first paragraph discusses basic economic models upon which the following paragraphs elaborate.

C)The fourth paragraph provides an example of how price elasticity of demand affects the duration of price changes.
D)The fourth paragraph describes a factor that influences the concept defined in the first paragraph.

A)sports cars would become cheaper
B)fewer sports cars would be sold

A)introducing several factors which affect price elasticity of demand
B)pointing out the problematic nature of basic economic models
C)describing the economic concept of price elasticity of demand and the factors which affect it
D)demonstrating that price has little effect on demand
E)showing that available substitutions and necessity of a product are the most important factors that affect price elasticity of demand

B. show that a product can still be considered necessary even if it is not a physical necessity of life

Can someone elaborate why OA of q1 is E? I guess I basically want to determine what constitutes defining vs discussed.

Hi,

The difference is not between defining and discussed but between "discussing different models" and "defining a concept". Paragraph 1 defines price elasticity and elaborates on the factors that influence the said concept later on; it does not discuss any economic model per se. Hence, E.

Option A is talking about Economic model while option E is talking Economic concept. Economic model for example can be Capitalistic or Socialistic. Economic concept can supply, demand, Elasticity etc.

Hi urvashis09,

Could you help me choose between C and E , I find both the answers almost the same except the two words in the choices 'defines' and 'introduces'.

How do I differentiate between the two words, with the information given in the first para?

Thanks

Hi,

The difference is again not between the two words but between the two lines.

C)The first paragraph introduces an economic concept which is defined in the following paragraphs. Note that the first paragraph clearly "defines" the concept of price elasticity and the subsequent paragraphs elaborate on the concept further. This is a classic half right half wrong answer choice in the sense we can definitely say that the first para introduces an economic concept but the following paragraph do not define the concept in fact they elaborate on it.

E)The first paragraph defines an economic concept upon which the following paragraphs expand. This matches the structure perfectly. The first paragraph defines a concept and the next paragraphs further discuss the various factors that effect it.

1)What is the function of the first paragraph?

C)The first paragraph introduces an economic concept which is defined in the following paragraphs.
Definition is only given in para1 as stated in option E
E)The first paragraph defines an economic concept upon which the following paragraphs expand.

Every single word is important in eliminating options in RC.

Defining is the general definition while discussion is where the author elaborates on that definition (in this context) or a phenomenon by presenting his/her own understanding. A discussion is likely to consist of the positives and negatives of the topic in hand.
E is correct because only the para1 consists of definition and rest of the passage elaborates/ discusses that same topic.

Hope that makes sense.

Why the answer to Q2 Is C and not D?
In C isn’t it other way around, that the duration of price changes affects elasticity and not vice-versa as is stated in option C?
But as in option D, it describes another factor that affects elasticity (defined in 1st paragraph)

Official Explanation from Economist Gmat:
For this Structure question, we do not need to go beyond our Initial Reading:
Paragraph I: Price elasticity of demand (PED) is defined as how much demand for a product changes as its price changes
Paragraph II: The number of substitutions available for a product affects PED
Paragraph III: The breadth of definition of a product affects PED
Paragraph IV: The duration of the price change affects PED
Paragraph V: The product's necessity to the customer affects PED

The first paragraph defines the concept of price elasticity of demand, and the rest of the passage shows several factors which influence the degree of elasticity.

For this Structure question, we do not need to go beyond our Initial Reading:
The fourth paragraph introduces the concept of duration of price change, which has an effect on the elasticity of demand for a product.

This is an Inference question. We should begin by reading about sports cars, which are mentioned in the last sentence of the third paragraph. From the information in the question, we can infer that the demand for such cars is inelastic because they are a symbol of luxury and prestige.
Because prestige and luxury are the reasons for the inelasticity of demand for sports cars, we can infer that if sports cars were not so well-regarded, demand for them would become more elastic.

For this Main Idea question, we do not need to go beyond our Initial Reading:
The first paragraph introduces price elasticity of demand and the rest of the paragraphs describe factors which affect it.

Hey dabaobao,

5 minutes to read the passage is a little too much to read the passage.

Identifying what is important and what is not would help you bring that time to under half of what you have taken.

To understand that, please watch the video below.

All the best

Thanks,
