Question

Дохід споживача зріс з 500 грн. до 1200 грн. При цьому споживач скоротив величину попиту на певну групу товарів з 20 одиниць до 5 одиниць. Розрахувати коефіцієнт еластичності, охарактеризувати товари.​

Answer 1

Ответ:

Коефіцієнт еластичності попиту можна розрахувати за формулою:

Е = (ΔQ/Q) / (ΔP/P),

де ΔQ - зміна кількості товару, Q - початкова кількість товару, ΔP - зміна ціни, P - початкова ціна.

У нашому випадку:

ΔQ = 5 - 20 = -15

Q = 20

ΔP = (1200 - 500)/500 = 1.4

P = 500

Е = ((-15/20) / (1.4/1)) = -1.07

Отже, коефіцієнт еластичності попиту дорівнює -1.07. Це означає, що товари є еластичними, тобто зміна доходу споживача призводить до значної зміни попиту на товари. У нашому випадку, збільшення доходу споживача на 140% (з 500 грн. до 1200 грн.) призвело до скорочення попиту на товари на 75% (з 20 одиниць до 5 одиниць).

Answer 2

Calculation of Elasticity Coefficient

To calculate the elasticity coefficient, we need to use the formula:

Elasticity Coefficient = Percentage Change in Quantity Demanded / Percentage Change in Income

Given the information provided, the percentage change in quantity demanded is:

Percentage Change in Quantity Demanded = ((Initial Quantity Demanded - Final Quantity Demanded) / Initial Quantity Demanded) * 100

Substituting the values, we get:

Percentage Change in Quantity Demanded = ((20 - 5) / 20) * 100 = 75%

The percentage change in income is:

Percentage Change in Income = ((Final Income - Initial Income) / Initial Income) * 100

Substituting the values, we get:

Percentage Change in Income = ((1200 - 500) / 500) * 100 = 140%

Now, we can calculate the elasticity coefficient:

Elasticity Coefficient = Percentage Change in Quantity Demanded / Percentage Change in Income = 75% / 140% ≈ 0.54

Interpretation of Elasticity Coefficient

The elasticity coefficient measures the responsiveness of quantity demanded to changes in income. In this case, the elasticity coefficient is approximately 0.54.

Since the elasticity coefficient is less than 1, we can conclude that the goods in question are income inelastic. This means that the quantity demanded of these goods is not very responsive to changes in income. A 1% increase in income leads to a less than 1% increase in quantity demanded.

It is important to note that without specific information about the goods in question, we cannot provide further characterization of the goods based solely on the elasticity coefficient. The elasticity coefficient only tells us about the responsiveness of quantity demanded to changes in income, not about the nature or type of the goods themselves.
