Topics in Production and Costs

1

1. Production Function and Isoquants

  • Production function gives the maximum quantity of output for different combinations of inputs.
  • It is defined for a given technology. If technology improves, a new production function comes into existence.
  • A firm can produce only if both inputs are available. If either input is zero, output is zero.

2. Short Run, Long Run, TP, AP and MP

  • In the short run, at least one factor of production cannot be varied and therefore remains fixed.
  • In the long run, all factors of production can be varied. There is no fixed factor.
  • Short run and long run are defined by whether all inputs can be varied, not by calendar time.

3. Law of Variable Proportions and Curve Shapes

  • The law of variable proportions states that marginal product initially rises with employment level and then falls after a certain point.
  • It is also called the law of diminishing marginal product.
  • This happens because the ratio of fixed to variable factors changes as more of the variable input is added.

4. Returns to Scale and Cobb-Douglas Production Function

  • Returns to scale apply only in the long run because both inputs must change together.
  • When all inputs increase in the same proportion and output increases in the same proportion, the production function shows constant returns to scale.
  • When output increases by a larger proportion than inputs, the production function shows increasing returns to scale.
