Suppose Ralph has a chicken processing plant with the total cost function shown in the accopmanying table.
fixed cost: $800 # of workers hired: 8 Why does total cost increase faster as output increases?: There are diminishing returns to labor.
A firm's ___________________ are costs that are incurred even if there is no output. In the short run, these costs ___________________ as production increases.
fixed costs; do not change
One thing that distinguishes the short run and the long run is
the existence of at least one fixed input.
Which of the statements is not true?
- NOT TRUE: Costs that are small and unimportant with little impact on profits are called marginal costs. - Marginal cost and marginal productivity are inversely related. - Marginal cost is the change in a firm's total cost due to a one‑unit change in output. - A marginal cost curve will always intersect the average total cost curve at the minimum average total cost. What is the marginal cost of the eighth unit based on the table? $50
Labor costs represent a large percentage of total costs for many firms. According to data from the Bureau of Labor Statistics, U.S. labor costs were up 2.0% in 2015, compared to 2014.

An increase in labor productivity means that each worker can produce more output. Recent data on productivity show that labor productivity in the U.S. nonfarm business sector grew by 1.7% between 1970 and 1999, by 2.6% between 2000 and 2009, and by 1.1% between 2010 and 2015.
Increases in labor productivity will lower the cost of production, counteracting the effects of the labor cost increase.

The long run is best defined as a time period
during which all inputs can be varied.
Given the assumptions of a perfectly competitive industry, explain why firms operating in that industry are reluctant to invest in new technological development. Firms in a perfectly competitive industry are reluctant to invest in new technological development due to free entry and exit of firms. If any firm invested in new technology and earned profits, other firms will enter the market, which will cause the price to fall and the profits to get eroded. Furthermore, due to the product being standardized and producers being price-takers, they cannot charge a higher price and recoup their investment.
free entry and exit of firms enter standardized price-takers
A firm's ___________________ are costs that increase as quantity produced increases. These costs often show ___________________ illustrated by the increasingly steeper slope of the total cost curve.
variable costs; diminishing marginal returns
In the long run, choosing a higher level of fixed cost shifts the long-run average total cost curve upward.
False; choosing a higher level of fixed cost causes rightward movement along the long-run average total cost curve. The average total cost curve remains the same.

Perfect Competition and the Supply Curve — End of Chapter Problem Over the last three years, Christmas tree prices have increased from an average of $35 per tree to over $75 per tree. How would a Christmas tree farm and the overall industry respond to the price change under the following circumstances? Be sure to explain how your answer depends on the elasticity of supply. a. The price increase is a result of an increase in demand from younger generations, mainly millennials, increasing their desire to purchase real Christmas trees. The Christmas tree farm and the overall industry will respond as follows In the long run, producers exit the market as the price is not high enough to cover costs, and they make losses. In the long run, the price decreases, and the market returns to its perfectly inelastic curve. In the short run, producers earn profits and increase supply. Supply is less elastic in the short run than in the long run. In the short run, the tree farms move down along their marginal cost curves as they have to use fewer inputs. b. The price increase is a result of fewer Christmas tree farms harvesting trees in response to consumers purchasing more artificial trees. The effect of the price increase on the Christmas tree industry will be as follows In the long run, the industry supply curve shifts to the left. In the short run, the tree farms exit the Christmas tree business and grow other lucrative plants. In the long run, as tree farms sell fewer trees, they make losses and exit the industry. In the short run, the increase in price leads to profits for tree farms. Solved
A. In the short run, producers earn profits and increase supply. Supply is less elastic in the short run than in the long run. B. In the short run, the increase in price leads to profits for tree farms.
Evaluate each of the following statements. a. A profit-maximizing firm in a perfectly competitive industry should select the output level at which the difference between the market price and marginal cost is greatest. This statement is false. The firm should select the output where market price is equal to marginal cost. b. An increase in fixed cost lowers the profit-maximizing quantity of output produced in the short run. This statement is false. This change does not impact price nor marginal cost, thus it does not impact the profit-maximizing output in the short run.
A. false. The firm should select the output where market price is equal to marginal cost. B. false. This change does not impact price nor marginal cost, thus it does not impact the profit-maximizing output

Your roommate is having difficulty understanding how a firm can keep operating despite losing money, earning a negative profit. How will firms respond to losing money? a. If price is below the firm's minimum average variable cost, the firm will shut down, since it will not be able to cover either its fixed costs or its variable costs. b. If price is below the firm's minimum average total cost but above its minimum average variable cost, the firm will continue operating in the short run, since it w
A. shut down not be able to cover either its fixed costs or its variable costs B. continue operating in the short run be able to cover its variable costs and some of its fixed costs .
An increase in fixed cost increases marginal cost.
False; fixed costs do not change with increases in output, so the change in total cost resulting from an increase in production will remain unchanged. Changes in fixed cost do not affect marginal cost.
The short-run average variable cost can never be less than the long-run average total cost.
False; short-run average variable costs do not include fixed costs, so short-run average variable cost may be lower than long-run average total cost for high levels of fixed cost.
When marginal cost is above average total cost, average total cost must be falling.
False; when marginal cost is above average total cost, then producing the next unit of output will be more costly than the average, increasing average total cost.
Perfect Competition and the Supply Curve — End of Chapter Problem A recent report found that Christmas trees have doubled in price over the last three years. The price surge is partly due to a glut of trees 10 years prior. During the Great Recession of 2008 many consumers reduced their purchases, leading to a surplus of trees and lower prices. Explain how a glut in trees 10 years prior could lead to higher prices today. Focus on how farms changed operations in response to the price decrease. Please select all that help explain the increase in Christmas tree prices. The glut in trees led farms to move up along their marginal cost curves to better deal with the reduced demand. Farms suffer from losses and cut back on production or exit the Christmas tree market due to the fall in demand in 2008. The demand for Christmas trees has increased in recent years due to the economic expansion. It takes seven to ten years for a Christmas tree to reach a height of six to seven feet.

Washington state is the largest producer of apples in the United States. In 2018, farms in Washington produced 171 million bushels of apples, nearly five times more than the next highest-producing state, New York. Many apple farms in Washington depend on migrant labor from Mexico and Central America. These countries were once reliable sources of labor, but farmers are now experiencing a large shortage of labor. Most migrant workers are choosing year-round positions in the construction industry instead of the seasonal work offered in agriculture, leaving apple farms relying on undocumented migrant labor. With fewer undocumented workers, labor costs have soared, forcing many farmers to invest in expensive mechanical harvesting devices. Firms will experience an increase in average fixed costs as they invest in expensive mechanical harvesting devices. Firms who cannot break even due to higher production costs will exit the industry. Firms will experience an increase in average variable costs as labor becomes more expensive. Firms have to cut back on growing apples, and the market supply of apples will decrease.

Marty's Frozen Yogurt is a small shop that sells cups of frozen yogurt in a university town. Marty owns three frozen yogurt machines. His other inputs are refrigerators, frozen yogurt mix, cups, sprinkle toppings, and, of course, workers. He estimates that his daily production function when he varies the number of workers employed (and at the same time, of course, yogurt mix, cups, and so on) is as shown in the accompanying table.
Fixed inputs: - refrigerators - frozen yogurt machines - frozen yogurt shot Variable inputs: - frozen yogurt mix - cups - sprinkle toppings - labor c. Marginal product of the first worker: 110 Marginal product of the second worker: 90 Third worker: 70 Why does marginal product decline as the number of workers increases?: The number of workers increases, but the number of yogurt machines does not. Since additional workers reduce each worker's access to capital, each additional worker contributes less to total output.

A decreasing marginal product tells us that marginal cost must be rising.
True; a decreasing marginal product implies that additional units of output require larger and larger increments of the variable input; thus, marginal cost increases.
An increase in fixed cost increases the minimum-cost output.
True; if fixed costs increase, the spreading effect strengthens relative to the diminishing returns effect. Accordingly, the level of output that minimizes average total cost rises.
The short-run average total cost can never be less than the long-run average total cost.
True; the long-run average total cost is given by the ideal level of fixed input, whereas short-run average total cost is given by an arbitrary level of fixed input.
The production function for Marty's Frozen Yogurt is shown in the accompanying table. Marty pays each of his workers $80 per day. The cost of his other variable inputs is $0.50 per cup of yogurt. His fixed cost is $100 per day.

The first sushi restaurant opens in town. Initially, people are very cautious about eating tiny portions of raw fish, as this is a town where large portions of grilled meat have always been popular. Soon, however, an influential health report warns consumers against grilled meat and suggests that they increase their consumption of fish, especially raw fish. The sushi restaurant becomes very popular and its profit increases.
a. In the short run, we expect other firms to enter because of positive profits, and, in the long run, we expect prices to decrease and the profit for the original sushi restaurant to decrease in the town's sushi restaurant industry. b. Local steakhouses suffer from the popularity of sushi and start incurring losses. In the long run, we expect the number of steakhouses to decrease in town.

Changes in the prices of key commodities have a significant impact on a company's bottom line. For virtually all companies, the price of energy is a substantial portion of their costs. In addition, many industries, such as those that produce beef, chicken, high-fructose corn syrup, and ethanol, are highly dependent on the price of corn. In particular, corn has seen a significant increase in price.
a. There is usually a fixed energy cost associated with overhead that does not change with output, but producing more output typically takes more energy. c. Corn is a raw ingredient in the production of ethanol. An ethanol producer adjusts its corn purchases to meet its ethanol production targets
