Chapter 5: The Production Process and Cost

You are an efficiency expert hired by a manufacturing firm that uses K and L as inputs. The firm produces and sells at a given output. If w = $40, r = $100, MPL = 20 and MPK = 40, is the firm minimizing cost in the long run? Carefully explain your answer. What is your advice to the firm?

Chapter 7: Nature of Industry

Would integration between the following types of firms constitute a horizontal, a vertical, or a conglomerate merger? Explain your answers:

  • A food company and a drug company.
  • A milk producer and a cheese producer.
  • A computer chip manufacturer and a silicon producer.

Chapter 7: Perfect Competition, Monopoly, Monopolistic Competition

The graph below illustrates a monopolist in the short run.

a. How many units will this firm produce? How can you tell?

b. What price will this firm charge? How can you tell?

c. What is the maximum amount of profit this firm will earn? How can you tell?

d. Describe some of the barriers to entry that might allow a monopolist to continue to earn positive profits in the long run.

Paper For Above Instructions

In the context of managerial economics, evaluating the efficiency of production processes and the structure of industries is vital for business decision-making. This paper will address the questions provided in Exam 2 for ECON 525, encompassing the production process and cost, as well as industry mergers and monopolistic practices.

Chapter 5: The Production Process and Cost

In evaluating whether the manufacturing firm is minimizing its costs, we need to utilize the concept of the marginal product of labor (MPL) and the marginal product of capital (MPK). The cost-minimization condition in production states that a firm will minimize its costs when the ratio of the marginal products is equal to the ratio of input prices. Specifically, this is expressed through the following equation:

Cost Minimization Condition:

MPL / MPK = w / r

Where:

  • MPL is the marginal product of labor.
  • MPK is the marginal product of capital.
  • w is the wage rate.
  • r is the rental rate of capital.

Using the provided values: MPL = 20, MPK = 40, w = $40, and r = $100, we first calculate the left side of the equation:

MPL / MPK = 20 / 40 = 0.5

Now, we calculate the right side:

w / r = 40 / 100 = 0.4

Since 0.5 (MPL/MPK) is greater than 0.4 (w/r), it indicates that the firm is not minimizing its costs. According to the cost-minimization principle, the firm should substitute some capital for labor to reduce costs. Therefore, my advice to the firm is to increase the use of capital (K) relative to labor (L) until the marginal products align with the input price ratio. This adjustment will help the firm achieve the lowest possible cost per unit of output.

Chapter 7: Nature of Industry

Integration between firms can take on different forms, such as horizontal, vertical, or conglomerate mergers, depending on their market relationships.

A. Food Company and Drug Company

The integration between a food company and a drug company would constitute a conglomerate merger because these two companies are in entirely different markets and sectors. Their business operations do not directly overlap, and the acquisition aims to diversify product offerings.

B. Milk Producer and Cheese Producer

The integration between a milk producer and a cheese producer exemplifies a horizontal merger since both entities operate within the dairy industry, dealing with similar products. This type of merger can enhance market share and eliminate competition.

C. Computer Chip Manufacturer and Silicon Producer

Lastly, the merger between a computer chip manufacturer and a silicon producer can be classified as a vertical merger. This is because the chip manufacturer relies on silicon as a key input in production, thus representing a combination of different stages in the supply chain.

Chapter 7: Perfect Competition, Monopoly, Monopolistic Competition

A. Output Determination

In a monopolistic setting, the determination of output occurs where marginal revenue (MR) equals marginal cost (MC). Assuming that the graphical representation shows the intersection of MR and MC at 40 units, we can infer that the monopolist will produce 40 units of output.

B. Price Determination

The price that the firm will charge can be determined using the demand curve. Given that the monopolist will produce 40 units, the price level will correspond to where this quantity intersects the demand curve. If it intersects at $120, that will be the price charged to consumers.

C. Profit Maximization

The maximum profit is calculated as the difference between total revenue and total cost at the level of output determined above. If total revenue (TR) at 40 units is $4,800 (40 units * $120), and total cost (TC) is $3,000, the maximum profit would be $1,800.

D. Barriers to Entry

Barriers to entry that can allow a monopolist to maintain positive profits include:

  • High capital requirements that deter new entrants.
  • Exclusive access to essential resources.
  • Government regulations that provide licenses or patents.
  • Strong brand loyalty that creates customer preference.
  • Economies of scale that make it difficult for smaller firms to compete.
