Given ๐1 = 26 โ 35๐1 + 2๐2 + 0.01๐ผ , where ๐1 is the price of good 1, ๐2 is the price of good 2, and ๐ผ is income
a. Calculate the price elasticity of demand when
๐1 = 10, ๐2 = 5, ๐ผ = 1000. Is demand for good 1 elastic or inelastic?
Explain.
To calculate the price elasticity of demand, we can use the following formula:
E = (%ฮQ1 / %ฮp1)
Where E is the price elasticity of demand, %ฮQ1 is the percentage change in quantity demanded of good 1, and %ฮp1 is the percentage change in the price of good 1.
To calculate the percentage change in quantity demanded (%ฮQ1), we need to know the initial quantity demanded and the new quantity demanded. However, these values are not given in the question. Without this information, we cannot calculate the price elasticity of demand.
Therefore, we cannot determine whether the demand for good 1 is elastic or inelastic based on the given information.
Well, let's put on our economic detective hats and solve this mystery! We're dealing with the price elasticity of demand here, which sounds as mysterious as a magician's disappearing rabbit.
First, we've got this equation that's longer than a CVS receipt: ๐1 = 26 โ 35๐1 + 2๐2 + 0.01๐ผ. Now, you might think it's a secret code, but it's just economics trying to be all cryptic and fancy.
Now, when ๐1 = 10, ๐2 = 5, and ๐ผ = 1000, let's plug these values into our magic equation and see what pops out. Drumroll, please!
๐1 = 26 โ 35(10) + 2(5) + 0.01(1000)
After some quick math (and a couple of cups of coffee), we find that ๐1 = -115. Yep, you read that right, negative! Demand for good 1 has gone into hiding faster than a cat when it hears a vacuum cleaner.
Now, let's talk elasticity. If demand is as elastic as a bungee cord, it means a small change in price sends people running for the hills, screaming, "I'm not paying that much!" But if it's inelastic, people are more loyal than a dog guarding its favorite chew toy.
In our case, with a negative quantity, we've got some crazy elastic demand! People are fleeing from good 1 like it's the haunted house at the carnival. So, demand for good 1 is elastic, and that's why it's doing the disappearing act โ it can't handle those high prices! ๐ฉ๐ซ
Apologies for the confusion caused earlier in my response. It seems there was a misunderstanding regarding the interpretation of the equation and calculation of quantity.
Given the equation ๐1 = 26 โ 35๐1 + 2๐2 + 0.01๐ผ, we can interpret it as a demand function for good 1, where ๐1 represents the price of good 1, ๐2 is the price of good 2, and ๐ผ is income.
To calculate the price elasticity of demand, we need to take the derivative of ๐1 with respect to ๐1 and then multiply it by ๐1/Q1 (the ratio of the price of good 1 to the quantity demanded of good 1). This will give us the price elasticity of demand for good 1.
Taking the derivative of ๐1 with respect to ๐1, we get:
d๐1/d๐1 = -35
Now, to calculate the price elasticity of demand, ๐ธ, we need to multiply d๐1/d๐1 by ๐1/Q1, where ๐1 = 10 and ๐2 = 5. However, we do not have the values for ๐1 (quantity demanded of good 1) and ๐1 (initial quantity demanded of good 1) given in the question, so we cannot calculate ๐ธ.
Unfortunately, without the necessary information, we cannot determine the price elasticity of demand or whether the demand for good 1 is elastic or inelastic.
To calculate the price elasticity of demand for good 1, we need to use the following formula:
Eแตข = (โ๐แตข/โ๐แตข) * (๐แตข / ๐แตข)
Where:
- Eแตข represents the price elasticity of demand for good i
- ๐แตข represents the quantity demanded of good i
- ๐แตข represents the price of good i
In this case, we are looking at good 1, so we are interested in calculating Eโ.
Given:
๐โ = 26 โ 35๐โ + 2๐โ + 0.01๐ผ
๐โ = 10
๐โ = 5
๐ผ = 1000
Let's calculate Eโ step-by-step.
Step 1: Calculate โ๐โ/โ๐โ
To do this, we differentiate ๐โ with respect to ๐โ and hold all the other variables constant.
โ๐โ/โ๐โ = -35
Step 2: Calculate ๐โ
To do this, we substitute the given values of ๐โ, ๐โ, and ๐ผ into the equation ๐โ = 26 โ 35๐โ + 2๐โ + 0.01๐ผ.
๐โ = 26 โ 35(10) + 2(5) + 0.01(1000)
= 26 โ 350 + 10 + 10
= -304
Step 3: Calculate Eโ
Now we can substitute the values obtained in steps 1 and 2 into the price elasticity formula.
Eโ = (โ๐โ/โ๐โ) * (๐โ / ๐โ)
= (-35) * (10 / -304)
= 1.1513
Since the price elasticity of demand (Eโ) is greater than 1, demand for good 1 is elastic. This means that a 1% increase in price would lead to a more than 1% decrease in quantity demanded, indicating a relatively big sensitivity of demand to price changes.
To calculate the price elasticity of demand (PED), we need to take the derivative of the demand function with respect to the price of good 1 (p1), and then multiply it by the ratio of p1 to the quantity demanded:
PED = (โQ1/โp1) * (p1/Q1)
First, let's find the derivative of the demand function with respect to p1:
โQ1/โp1 = -35
Next, substitute the values into the formula:
PED = (-35) * (10 / Q1)
Now, we need to find the value of Q1 by substituting the given values (p1 = 10, p2 = 5, I = 1000) into the demand function:
Q1 = 26 - 35p1 + 2p2 + 0.01I
= 26 - 35(10) + 2(5) + 0.01(1000)
= 26 - 350 + 10 + 10
= -304
Finally, substitute the value of Q1 into the PED formula:
PED = (-35) * (10 / -304)
โ 1.15
The price elasticity of demand for good 1 is approximately 1.15. Since the magnitude of the PED is greater than 1, demand for good 1 is considered elastic.
Explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to a change in price. If the magnitude of the PED is greater than 1, it indicates that demand is elastic, meaning a small change in price will result in a proportionally larger change in quantity demanded. In this case, a 1% increase in the price of good 1 would lead to approximately a 1.15% decrease in quantity demanded, indicating that demand is relatively sensitive to price changes.
