$800

With current technology, suppose a firm is producing 400 loaves of banana bread daily. Also assume that the least-cost combination of resources in producing those loaves is 6 units of labor, 7 units of land, 2 units of capital, and 1 unit of entrepreneurial ability, selling at prices of $40, $60, $60, and $20, respectively. Assume the firm can sell these 400 loaves at $2 per unit. What is its total cost

Assume now that a new technique, technique 4, is developed. It combines 2 units of labor, 2 of land, 6 of capital, and 3 of entrepreneurial ability. In view of the resource prices in the table, will the firm adopt the new technique?

Yes

Evaluate this statement: "The market system causes the economy to conserve most in the use of resources that are particularly scarce in supply. Resources that are scarcest relative to the demand for them have the highest prices. As a result, producers use these resources as sparingly as is possible." Does your answer to part c, above, bear out this contention?

$16 billion

Follows a circular flow chart: Suppose that businesses buy a total of $130 billion of the four resources (labor, land, capital, and entrepreneurial ability) from households. If households receive $72 billion in wages, $16 billion in rent, and $26 billion in interest, how much are households paid for providing entrepreneurial ability?

The organic soap company

Suppose Natasha currently makes $50,000 per year working as a manager at a cable TV company. She then develops two possible entrepreneurial business opportunities. In one, she will quit her job to start an organic soap company. In the other, she will try to develop an Internet-based competitor to the local cable company. For the soap-making opportunity, she anticipates annual revenue of $465,000 and costs for the necessary land, labor, and capital of $395,000 per year. For the Internet opportunity, she anticipates costs for land, labor, and capital of $3,250,000 per year as compared to revenues of $3,275,000 per year. If she does quit her current job, which opportunity would she pursue?

Suppose that Sam receives a $10 gift card for the local coffee shop, where she only buys lattes and muffins. If the price of a latte is $5 and the price of a muffin is $2, then we can conclude that Julia can buy 2 lattes or 5 muffins if she chooses to buy only one of the two goods. should only buy lattes. should only buy muffins. can buy 2 lattes and 5 muffins with her $10 gift card.

This technique represents the least-cost combination.

Why?

For each of the following situations, would the attainable set of combinations that you can afford increase or decrease? Your budget increases from $100 to $150 while the prices stay the same:

The unemployment rate is 4.8 percent.

Which of the following represents a positive economic statement? Taxes should not be increased since that will lower spending. The government should extend unemployment benefits. The unemployment rate is too high. The unemployment rate is 4.8 percent.

no change explanation: If the firm is earning positive economic profit, other firms or individuals will want to produce banana bread. Thus, resources will flow toward this bakery good. If the firm is suffering from an economic loss, then resources would flow away from this bakery good, as firms or individuals would exit the market to avoid the loss. If economic profit equals zero, there will be no change, as no new firms will enter the market and no firms will exit.

With current technology, suppose a firm is producing 400 loaves of banana bread daily. Also assume that the least-cost combination of resources in producing those loaves is 6 units of labor, 7 units of land, 2 units of capital, and 1 unit of entrepreneurial ability, selling at prices of $40, $60, $60, and $20, respectively. Assume the firm can sell these 400 loaves at $2 per unit. If this firm's situation is typical for the other makers of banana bread, will resources flow toward or away from this bakery good?

Yes explanation: explanation: If the firm is earning positive, including zero, economic profit, it will continue to produce banana bread. However, if the firm is losing money (suffering a loss because total cost exceeds total revenue), it will stop producing banana bread.
