The government has an effective price ceiling in place. The government then decides to decrease the price ceiling by 20%. Describe 1) what will happen to quantity demanded and quantity supplied with this change, 2) how elasticity relates to the changes, and 3) the resulting effect on the market. Where is price relative to where the equilibrium price would be if there were no price controls?
The quantity demanded will increase since the price ceiling is lower, meaning the highest price a producer can charge has decreased by 20%. The Quantity supplied will probably not change much, it could increase because of the need to make up for the lack of profit. The market will be pretty elastic. The price is higher that where the equilibrium price would be, that is why it is a ceiling.

Doug goes grocery shopping. He sees that each apple is $1 and each banana is 50 cents. His marginal utility for the first apple is 5 and his marginal utility of the first banana is 4. First, what is his marginal utility per dollar of the first apple and the first banana? He has $10 and he spends all of it on apples and bananas. Describe his decision making process for how many apples and bananas he will buy and why. (Note: You will not be able to solve a numeric answer for how many of each he will buy, but you can describe why Doug decides to buy more of one).
His marginal utility per dollar of his first apple is 5 and the marginal utility per dollar of the first banana is 8 (=4/.5). If he only had $1, he would buy two bananas, but since he has $10, he will be able to buy more. For each banana he buys, his marginal utility for that banana goes down. He will continue putting bananas into his basket until his marginal utility per dollar of bananas is less than or equal to 5. At that point, if he still has some of his $10 left, he will put some apples in the basket. With each apple, his marginal utility per apple will go down. He'll continue buying apples and bananas until the bang for buck of each fruit is equivalent and he has spent his whole budget.
