Suppose the firm whose demand and cost curves are represented in the table above operates in a perfectly competitive market. What is the profit-maximizing output?
25 The price in a competitive market does not change because of one firm's actions, so it is always $16. The total revenue is calculated by multiplying price by output.The total revenue (TR) is calculated by multiplying the quantity (output) by the price ($5). MR is the difference in TR from the previous amount of production to the current amount of production. MC is calculated by taking the difference in cost between each level of output. Profit is maximized when MR = MC.The profit-maximizing output is where MC = MR, at a quantity of 25.

Candy makers face high prices for cocoa butter, the special ingredient that gives chocolate its melt-in-the-mouth texture. This event will be shown in
D. Graph D. Since the cocoa butter is an ingredient in the product of chocolate, the change in the cost of this ingredient will affect the supply curve. Since the cocoa butter is more expensive, it will lower profit margins for firms, and the supply curve will shift. The demand curve does not shift, because ingredient cost does not shift the demand curve.
The market for breakfast cereal is currently in equilibrium. Suddenly there is a storm that destroys the wheat that farmers had been growing for the cereal manufacturer. What will happen to the cereal market after the storm?
D. Supply will decrease. A storm that destroyed the wheat crops would cause the price of that grain to rise. Given that grains are an important input in the manufacture of cereal, the rise in the price of grain represents an increase in input prices for cereal. This is represented in the cereal market as a leftward shift of the supply curve and no change in the demand curve.

As a waiter you earn $60,000 per year, including tips. Someone offers you a new job as an economic consultant, which pays $100,000 per year. In order to be a consultant, you'll need to rent an office and purchase supplies and new computer equipment. We can conclude which of the following?
If the explicit cost for the consulting job is $25,000 per year, your economic profit is equal to $15,000. FEEDBACK: Economic profits are calculated by subtracting implicit cost from accounting profit. With explicit costs of $25,000, the accounting profit is equal to $75,000. Because you're giving up your next best job, being a waiter, the implicit cost of being a consultant is $60,000. Therefore, your economic profit is equal to $15,000.

You're an entrepreneur and had a great idea to sell shoes that have springs installed in them to make walking easier. However, the development costs were so high that the shoes are priced 15 times higher than shoes without springs. As a result, many of the shoes have gone unsold. What possible event could eliminate the disequilibrium in the market for shoes?
B. There is an increase in income and "spring shoes" are a normal good. When there are too many "spring shoes" available, what is revealed is a surplus, where quantity supplied is greater than quantity demanded. On a graph, a surplus is illustrated with a horizontal line above the equilibrium point. The surplus can be removed as quantity demanded increases or when quantity supplied falls. In this case, an increase in income increases the demand for normal goods like "spring shoes," thus removing the surplus.
According to the Food and Drug Administration, "the ultraviolet (UV) radiation from these devices [sunlamps and tanning beds] poses serious health risks." As a result of reading this, the local mayor decides to introduce legislation that will put a 10% excise tax on tanning consumers. From an economic point of view, this will
B. shift the demand curve leftward for tanning.The excise tax lowers demand because consumers must now pay a higher tax in addition to the price they pay for the good. People will tan less because they now have to factor in the extra cost. This will be shown as a leftward shift of the demand curve.
There are a number goods that over time, for a variety of reasons, transition from being a normal good to an inferior good or from being an inferior good to a normal good. One such example of a good is the Toyota Camry. In the 1980s, more income for a household usually resulted in more Camry's being purchased. However, today more Toyota Camry's are purchased by households that have experienced a reduction in income.How could this happen?
D. The Camry becomes an inferior good because the good is now perceived as lower in quality than a Lexus. A normal good like a Camry can become an inferior good if it is perceived to be a lower quality good. What causes a person with more income to buy less of a product?
You are a producer of tortillas. In the market for tortillas, two events happen simultaneously: there is a decrease in the price of corn used to make your tortillas, and there are headlines that promotes the link between eating tortillas and reducing heart attacks.Which of the following is a consequence?
D. We know the quantity will increase, but we don't know what will happen to the price unless we know the size of the shifts. The cost of making tortillas has decreased due to a cheaper ingredient, so the supply of tortillas will increase. The headlines linking lower rates of heart attacks with consumption of tortillas will increase the demand for tortillas. Both of these changes increase the equilibrium quantity of tortillas. To determine whether price will increase or decrease, we need to know whether the shift in supply or the shift in demand is greater.
