What to Focus On
- A firm is a producer that uses inputs to produce output.
- Production function shows maximum output from given inputs and given technology.
- If technology changes, the production function changes.
- An isoquant shows input combinations producing the same output.
- Isoquants are negatively sloped when marginal products are positive.
- The same output can often be produced by different input combinations.
- In the short run, at least one factor remains fixed.
- In the long run, all factors are variable.
- Short run and long run depend on variability of inputs, not time length.
Common Mistakes to Avoid
Short run means a short calendar period, like a few days or months.
If one input is zero, the firm can still produce some output using the other input alone.
A production function shows the average output produced by inputs.
