Answer: See explanation
Explanation:
Income effect is when the demand for a particular good or service changes because the real income of the person has changed.
Substitution effect arises when there is a reduction in the sales for a good or service due to a price rise and therefore the consumers have switched to a cheaper alternative. For example, if the price of beef rises, the consumers may shift and purchase more of chicken.
Based on the above scenario, the following will then be:
• The price of lobster doubles, making Henri feel less wealthy. As a result, Henri buys fewer lobsters.
Income effect
Henry's real income has changed, he has more money and hence reduces the purchase for lobsters because he sees it as inferior good.
• The price of chicken falls by $0.75 a pound. Since chicken is now relatively less expensive than ground beef, Mary buys more chicken and less beef.
Substitution effect
Mary has moved to a cheaper alternative in this situation.
• The average price of a DVD falls by 15 percent. Tom buys more DVDs because his monthly movie budget can now stretch further.
Income effect
• Model Planes Incorporated reduces production of its wooden plane product line.
No effect
No effect here as it's neither income effect not substitution effect.
• Jessica sees that the price of orange juice is higher this week. She decides to buy less orange juice and more apple juice because orange juice is relatively more expensive.
