Question

A firm produces identical outputs at two different plants. If the marginal cost at the first plant exceeds the marginal cost at the second plant, how can the firm reduce costs and maintain the same level of output?

Short answer

Shift production from Plant 1 to Plant 2 until marginal costs equalize.

Step-by-step solution

Understanding the Problem

The firm produces an identical output at two plants. We are given that the marginal cost (MC) at the first plant is higher than the marginal cost at the second plant. The goal is to reduce costs while maintaining the same level of output.

Concept of Marginal Cost

Marginal cost refers to the increase in total cost when one additional unit of output is produced. If MC at Plant 1 is higher, producing extra units at Plant 1 costs more than at Plant 2.

Reallocation of Production

To reduce costs, the firm should decrease production at Plant 1 and increase production at Plant 2 until the marginal cost of producing an additional unit is the same at both plants. This ensures the total output remains unchanged and costs are minimized.

Equating Marginal Costs

Continue the adjustment in output between the plants until the marginal cost at both plants is equal. Mathematically, find a production level where \( MC_1 = MC_2 \). At this point, the cost reduction is optimized without altering the total output produced by the firm.

Conclusion of Cost Minimization

By adjusting the production levels between the two plants to equalize their marginal costs, the firm maintains the desired total output at a minimized cost.

Key concepts

cost minimization

Cost minimization is a key economic principle for firms looking to reduce expenses while maintaining their desired output levels. The main goal is to produce goods or services at the lowest possible total cost. To achieve cost minimization, firms analyze various production factors, including labor, materials, and plant location. In the scenario provided, the firm is producing identical outputs at two plants with differing marginal costs. By understanding that the marginal cost at one plant is higher than at another, the firm can strategically adjust operations to maintain output while minimizing costs. This involves balancing the production levels between plants to ensure that overall production efficiency is achieved and costs are minimized. Companies utilize mathematical models and calculations, such as equating marginal costs, to find the most cost-effective production allocation.

production reallocation

Production reallocation is a strategic move to enhance efficiency and reduce costs by shifting output from one production location to another. In the case of our firm, it involves adjusting the output between two plants to ensure that the production process is as efficient as possible. When the marginal cost is higher in one plant compared to another, reallocating production to the plant with the lower marginal cost is advantageous. This method not only reduces total production costs but also leverages the varying efficiencies of each plant effectively. Practical steps for reallocation might include:

• Assessing current production capabilities at each plant.
• Calculating the marginal cost for each unit produced at both plants.
• Increasing production at the plant where marginal costs are lower.
• Decreasing production at the plant where marginal costs are higher.

This balanced reallocation ensures that total output remains constant while total production costs are reduced.

identical outputs

Producing identical outputs implies that a firm’s products from different plants are indistinguishable in terms of quality and functionality. This is crucial for ensuring consistent customer satisfaction and meeting market demands effectively. In the context of cost management, identical outputs mean that firms can freely shift production between plants without affecting the quality of the goods. For the given exercise, maintaining identical outputs allows the firm to reallocate production without concern about quality discrepancies. Achieving identical outputs typically requires firms to:

• Maintain standardized production processes across different plants.
• Ensure uniform training and qualifications for staff.
• Use consistent materials and machinery.
• Implement regular quality checks.

By securing identical output, firms can take cost-reducing actions like production reallocation confidently, knowing that product quality remains uncompromised.

plant production efficiency

Plant production efficiency is the measure of how effectively a plant converts resources into final products. An efficient plant utilizes inputs like labor, machinery, and materials to produce outputs with minimal waste or unnecessary expense. For the given problem, enhancing plant production efficiency involves evaluating the marginal costs at each plant and adjusting output levels accordingly. Factors that influence plant production efficiency include:

• Technology and equipment quality used in production.
• Worker skill levels and productivity.
• Optimal plant layout and workflow.
• Preventive maintenance and equipment upkeep.

Firms can boost plant production efficiency by investing in modern technologies, continuously training employees, and maintaining efficient work environments. By improving efficiency, firms can lower their marginal costs, making it possible to produce goods at reduced costs while maintaining the same output levels, as seen in the exercise.
