Question

При росте цены с 5 до 11 ден. ед. величина предложения увеличится с 13 до 17 тысяч штук. Коэффициент дуговой эластичности предложения равен ... С решением

Answer 1

Решение:
Коэффициент дуговой эластичности всегда лежит где-то между двумя показателями точечной эластичности для низкой и высокой цены.
Кd = ∆Q/∆Р * ((Р1+Р2)/( Q1+ Q2)
Ер = (13-17)/(5-11) * (5+11)/(13+17) = -4/-6*16/30 = 0,67*0,53 = 0,4
Ответ:  0,4.

Answer 2

Calculation of the Arc Elasticity of Supply

To calculate the arc elasticity of supply, we need to determine the percentage change in quantity supplied and the percentage change in price.

Given the information provided, the price increases from 5 to 11 monetary units, and the quantity supplied increases from 13,000 to 17,000 units.

To calculate the percentage change in quantity supplied, we use the formula:

Percentage Change in Quantity Supplied = ((New Quantity Supplied - Old Quantity Supplied) / Old Quantity Supplied) * 100

Substituting the values, we get:

((17,000 - 13,000) / 13,000) * 100 = 30.77%

To calculate the percentage change in price, we use the formula:

Percentage Change in Price = ((New Price - Old Price) / Old Price) * 100

Substituting the values, we get:

((11 - 5) / 5) * 100 = 120%

Now, we can calculate the arc elasticity of supply using the formula:

Arc Elasticity of Supply = (Percentage Change in Quantity Supplied / Percentage Change in Price)

Substituting the values, we get:

Arc Elasticity of Supply = 30.77% / 120% ≈ 0.2564

Therefore, the coefficient of arc elasticity of supply is approximately 0.2564.
