Firms and production - Production function - short run

7 important questions on Firms and production - Production function - short run

What is the production function in short run production?

  • Describes short-run production with one variable and one fixed output.
  • Maximum output from input: \( q \).
  • Inputs: Labour (\( L \)), Capital (\( K \)).
  • Function: \( q = f(L, K) \).
  • Assumes no waste, reflects maximum potential output.

What is meant by the flexibility of inputs in economic terms?

  • Variable input: Can be changed quickly.
  • Fixed input: Cannot be quickly changed.
  • Short run (SR): At least one input is fixed.
  • Long run (LR): All inputs are variable.

What is short run (SR) production in terms of input variables?

  • Short run (SR) production involves one variable input and one fixed input.
  • Typically, capital (K) is assumed to be fixed in this context, and labor (L) is variable.

What is an example of input flexibility in a dairy farm?

  • Staff number: Can change quickly in SR.
  • Land input: Fixed in SR.
  • Land availability: Can increase over LR.

What is the definition and formula for the Average Product of Labor (APL)?

  • Definition: Ratio of output to the amount of labor employed.
  • Formula: \( APL = \frac{q}{L} \)
  • - \( q \): Output
  • - \( L \): Amount of labor employed

How is the total product of labor (TPL) defined in SR production?

  • Total product of labor is defined as q = f(L, K).
  • Represents total output produced with given labor L, holding capital K constant.

What is the marginal product of labor (MPL) and how is it derived?

  • Marginal product of labor (MPL) is calculated as \( \frac{\partial q}{\partial L} = \frac{\partial f(L,K)}{\partial L} \).
  • Indicates additional output from an additional unit of labor, ceteris paribus.
