Total product curve, Marginal Product curve, Average product curve - and the relationship between marginal and average product

Understanding Production Concepts

• Total Product Curve:

  • Relationship between number of workers and output is crucial for understanding production efficiency.

  • Stages:

  • Increasing Marginal Returns: Initial input of labor yields substantial increases in productivity.

  • Diminishing Marginal Returns: After reaching a peak, adding more labor results in smaller increases in output.

  • Negative Returns: Eventually, further labor may decrease productivity.

• Calculating Average and Marginal Product:

  • The Average Product (AP) is defined as total product divided by the number of laborers.

  • The Marginal Product (MP) reveals the additional output from adding one more labor unit. Analysis of these products is essential to determine maximum efficiency.

  • The intersection of MP and AP curves provides critical insights into optimal labor deployment.

• Real-World Application Examples:

  • Educational assessment analogy: average test scores increase when higher scores are achieved; if lower scores are obtained subsequently, average remains unchanged. This principle applies to production metrics as well.

• Key Relationships in Production:

  • Maximizing AP occurs at the point where MP is equal to AP, and where the MP curve intersects the AP curve represents the highest output efficiency.

• Impending Exam Topics:

  • Importance of understanding production curves, the relationship between AP and MP, and concepts of marginal returns.

  • Recognizing these principles is crucial as they are recurring exam topics that assess understanding of economic production theories.
