A builder of custom motorcycles must choose between operating out of one garage or two. When the builder operates out of one garage, its average total cost of production is given by$$A T C_{1}=Q^{2}-6 Q+14.$$If it operates out of two garages, its average total cost of production is given by $$A T C_{2}=Q^{2}-10 Q+30.$$ What does this firm's LATC look like? Can you describe it as a function?

Short Answer

Expert verified
The firm's LATC is \( LATC(Q) = Q^2 - 10Q + 30 \). ATC_2 is always less than ATC_1.

Step by step solution

01

Understand the Problem

The problem provides us two different average total cost (ATC) functions for a builder: one for operating out of a single garage and another for two garages. The task is to find a Long-run Average Total Cost (LATC) which is the minimum of these two ATC functions for each quantity Q.
02

Express Given Functions

We have two functions given: \( ATC_1 = Q^2 - 6Q + 14 \) (for one garage) and \( ATC_2 = Q^2 - 10Q + 30 \) (for two garages). The LATC will be the point-wise minimum of these two functions.
03

Compare Functions to Find Crossovers

To find the quantities where one ATC becomes less than the other, set \( ATC_1 = ATC_2 \).\[Q^2 - 6Q + 14 = Q^2 - 10Q + 30\]Simplify to find the crossover points: \(-6Q + 14 = -10Q + 30\)\(4Q = 16 \)\(Q = 4\). Thus, they cross at \( Q = 4 \).
04

Analyze Regions of Costs

The equality point occurs at \( Q = 4 \). For \( Q < 4 \), we need to check which is lower by plugging a value (e.g. \( Q = 3 \)):\[ATC_1(3) = 3^2 - 6*3 + 14 = 5\]\[ATC_2(3) = 3^2 - 10*3 + 30 = 3\]Thus, \( ATC_2 \) is smaller for \( Q < 4 \). For \( Q > 4 \), check with \( Q = 5 \).\[ATC_1(5) = 5^2 - 6*5 + 14 = 9\]\[ATC_2(5) = 5^2 - 10*5 + 30 = 5\]\( ATC_2 \) remains smaller for \( Q > 4 \) as well.
05

Describe the LATC Function

Since \( ATC_2 \) is always less than or equal to \( ATC_1 \) both before and after the crossover point, the LATC function is the same as \( ATC_2 \): \[LATC(Q) = Q^2 - 10Q + 30\]for all \( Q \).

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Cost Functions
In economics, cost functions are vital as they depict how a firm's costs change with variations in the level of output. A cost function essentially binds the size of production to its cost and can take various forms depending on specific conditions.
In our scenario, two cost functions represent the average total cost (ATC) of producing custom motorcycles. The first, \( ATC_1 = Q^2 - 6Q + 14 \), applies when the firm operates out of one garage. The second one, \( ATC_2 = Q^2 - 10Q + 30 \), represents the cost when using two garages.
To comprehend these functions:- **\(Q^2\)** signifies increasing costs as production increases due to inefficiencies or resource limitations. - **\(-6Q\) and \(-10Q\)** imply cost reductions due to efficiencies gained as production rises.- **\(+14\) and \(+30\)** are fixed costs regardless of production levels.
Understanding cost functions enables businesses to make informed decisions about production, such as expanding facilities or optimizing output levels.
Economies of Scale
Economies of scale refer to the cost advantages that enterprises obtain due to scale of production. With increased output, the average costs per unit of production usually decrease because fixed costs are spread over a larger number of goods, and operational efficiencies are realized.
In the context of the exercise, the firm must choose between two operations: one garage or two garages.
- Operating two garages reduce costs for every production level compared to using a single garage, as indicated by the simpler structure and lower outcome in the second cost function \( ATC_2 = Q^2 - 10Q + 30 \).- This mirrors the concept of economies of scale, where expanding operations leads to lower costs per unit, thus favoring using two garages.
Economies of scale are pertinent in strategic planning for businesses seeking sustainable growth, emphasizing the importance of optimizing scale for cost efficiency.
Production Costs
Production costs encompass all costs associated with manufacturing goods. They are a combination of fixed and variable costs. Understanding these is crucial for determining pricing strategies and ensuring profitability.
In this exercise, two cost scenarios illustrate different production costs:- The fixed costs: \(+14\) and \(+30\), are constant regardless of the quantity produced. These might include rent for the garages or salaries of permanent staff.- The variable costs: \(Q^2 - 6Q\) and \(Q^2 - 10Q\), vary with the level of output.
Assessing both fixed and variable costs allows the firm to identify its break-even points and evaluate decision impacts, like switching from one to two garages. Such insights help maintain cost-effective production levels and aid in competitive pricing strategies.

Chris owns his own business restoring antique cars. Last year, he restored 24 cars, which he sold for \(\$ 1,100,000\). The parts and supplies necessary for the restoration totaled \(\$ 400,000 .\) He paid \(\$ 360,000\) to his six employees and a salary of \(\$ 110,000\) to himself. The rent and utilities on his building were \(\$ 80,000\). Recently, Chris received an offer to work as Jay Leno's personal auto restorer, at a salary of \(\$ 275,000 .\) Chris also received a \(\$ 180,000\) offer to host a car-related reality TV show for the Discovery Channel. Chris can only work one job. a. What is Chris's accounting cost? His accounting profit? b. What is Chris's economic cost? His economic profit? c. Compare what Chris earns in his current job (both his salary and his company's accounting profit) to his best outside offer. Does the figure you calculated look familiar? Does it shed any light on the meaning of economic profit?

Amanda owns a toy manufacturing plant with the production function \(Q=100 L-3,000\), where \(L\) is hired labor hours. Assume that Amanda has no fixed costs. a. Rearrange Amanda's production function to show how many workers Amanda would have to hire to produce a given level of output. In other words, isolate \(L\) on the left-hand side, expressing \(L\) as a function of \(Q\). b. Because Amanda has no fixed costs, all her costs derive from paying workers. In other words, \(T C=w \times L\). Substitute your answer from (a) into this equation to find Amanda's total cost function.

Each year on January \(1,\) millions of Americans, having made New Year's resolutions to lose weight and get in shape, purchase annual gym memberships. A CNN survey recently suggested that nearly \(30 \%\) of all New Year's resolutions are abandoned by February \(1 ; 80 \%\) by July. In other words, millions of people buy expensive gym memberships and then fail to use them. Does this indicate that they fell victim to the sunk cost fallacy? Or, does it suggest that they well understand the nature of sunk costs? Explain your answer.

The long-run marginal cost of Peter's pipes is given as $$L M C=20,000-400 Q+3 Q^{2}.$$ a. Divide total cost by \(Q\) to obtain Peter's long-run average cost of producing pipe. b. Exploit the relationship between \(L M C\) and \(L A C\) to find the quantity where \(L A C\) is at a minimum. c. What is the lowest possible average cost at which Peter can produce pipe? d. Over what range of output does Peter's Pipers experience economies of scale? Over what range of output does Peter's Pipers experience diseconomies of scale?

Who doesn't love kicking back after work with a snack and a good show? Everyone loves some free time \(\ldots\) but, of course, time isn't free! In the past 10 years, ridesharing services like Uber have become wildly popular. People who need to get from \(\mathrm{A}\) to \(\mathrm{B}\) value the ability to connect with a driver rapidly, rather than waiting for a scarce taxicab. And ordinary people (with a nice enough car) can earn a few extra bucks giving rides, working as little or as much as they please. Today, an estimated 2 million people drive for Uber, often evenings and weekends after they're finished the day at a full-time job. Explain how the growth of Uber reflects the way in which ride sharing has altered the opportunity cost of leisure.
