Answer #1

1.Ans: e) called firm's expansion path

Explanation:

An expansion path exhibits cost minimizing level of output where a given level of output is produced with a lowest cost combination of inputs. A given level of output is represented by an iso-quant and a lowest cost combination is represented by iso-cost line. So the curve connecting cost minimizing level of output is called firm's expansion path.

2.Ans: b) the marginal cost curve will cut the average cost curve at the average cost curve 's minimum.

Explanation:

When the marginal cost curve lies below the average cost curve then there will be increasing returns to scale in the production process . But when the marginal cost curve lies above the average cost curve then there will be decreasing returns to scale in the production process. So we can conclude that the marginal cost curve will cut the average cost curve at the average cost curve 's minimum with a production function that exhibits decreasing returns to scale.

3.Ans: d) whether there is time to change all inputs.

Explanation:

The distinction between the short and long run is that in the short run, some fixed factors are available with variable factors in the production process whereas in the long run , all factors of production are variable.
