ΔvoteAΔexpendA=β2+β4expendB→0.0382809+−6.63e−6expendB
2. Is the expected sign for b4 obvious?
Yes because the expendB alone is a negative and expendA is a positive leaving B4 to be a negative number .
Answer:
c) 10% more peanut butter on the shelves
Explanation:
Since peanut butter has a negative income elasticity of demand (-0.5) with a decrease in income, there should be an increase in the demand. This is usually true for cheaper goods or goods with low added value. The change in demand (D) is represented as follows:
As a result, you should stock 10% more peanut butter on the shelves.
The answer is c).
Answer:
That statement is true.
Explanation:
Basically, You put your money in saving if you intended to use that money for future consumption. You put your money in investment if you intended to make financial gain out of it.
For example,
Let's say that you want to buy a laptop that cost $700. You only able to spend $350 per month since you have to consider other more important payment such as rent or food. So you set aside $350 for two month and purchase the laptop at the end of the second month. This is an example of saving.
In another case let's say that you put that $350 in Bonds rather than purchasing laptop. You Let that bond mature and take a 3% interest as profit. Two month later, the value of your money is increased. This is an example of an investment.
The correct answer is: "I would recommend her not to increase the price, because with an elastic demand function this will cause a great decrease in the quantity demanded by consumers".
The demand function represents the quantity of a certain good or service that consumers are willing to purchase in the market at different price levels. The law of demand states that there is an inverse relationship between price and quantity demanded (ceteris paribus, hence, given that the rest remains equal). <u>Therefore, when the price charged decreases, the amount that consumers are willing to purchase increases. </u>
In turn, the elasticity of the demand function measures the sensitiveness of the quantity demanded by consumers when there is a certain price change. If the demand function is elastic it means that a price variation would generate an even larger variation (in the inverse direction of course!) in the quantity demanded. <u>This is the case of the lemonade stand therefore the girl should not increase prices because this will not help her to reach her objective quicke</u>r, as she would loss a greater proportion of units sold than the size of the price increase that would have allowed her to earn more per unit.
