Can be any goods or service.

Consider an everyday good or service. What are the most important, managerially significant, costs of supplying that good or service to you? Estimate and explain the costs from the best available information. Be sure to: i) Define the short-run period that you believe is managerially significant, and why; ii Identify which costs are variable and which are fixed, and provide estimates of the more managerially significant costs; ii) Draw and describe the likely nature of the short-run cost curve with respect to managerially significant quantities; iv Discuss implications for the business based on your analysis. This answer should not exceed 750 words and will be assessed holistically;

Here we are considering a good which is made of iron. So it belongs to heavy good industry.

In economics, a short run characterizes the time when one factor of production is fixed and another factor is variable. In this situation, the factors haven’t fully adjusted to the operations schedule and economic situations.

“long run” provides free access to the entrance and exit of companies. New companies can enter the industry in the market. here we are considering iron good as output which is denoted by Q

(ii)Average Fixed Cost (AFC)

The average fixed cost is the fixed cost per unit of output. It is obtained by dividing the total fixed cost by the number of units of the commodity produced.

Symbolically        AFC = TFC / Q

Where   AFC = Average fixed Cost TFC = Total Fixed cost

Q   = number of units of output produced

Suppose for a firm the total fixed cost is Rs 2000 when output is 100 units, AFC will be Rs 2000/100 = Rs 20 and when output is 200 units, AFC will be Rs 2000/200 = Rs10/- Since total fixed cost is a constant quantity, average fixed cost will steadily fall as output increases; when output becomes very large, average fixed cost approaches zero.

Average Variable cost (AVC): Average variable cost is the variable cost per unit of output. It is the total variable cost divided by the number of units of output produced.

AVC = TVC / Q

Where AVC = Average Variable Cost

TVC       = Total Variable Cost

Q            = number of units of output produced

Average variable cost curve is 'U' Shaped. As the output increases, the AVC will fall upto normal capacity output due to the operation of increasing returns. But beyond the normal capacity output, the AVC will rise due to the operation of diminishing returns.

Average Total Cost or Average Cost : Average total cost is simply called average cost which is the total cost divided by the number of units of output produced.

AC = TC / Q where AC = Average Cost TC = Total Cost

Q = number of units of output produced

Average cost is the sum of average fixed cost and average variable cost. i.e. AC = AFC+AVC

The average cost is also known as the unit cost since it is the cost per unit of output produced. The following figure shows the shape of AFC, AVC and ATC in the short period.

From the figure , it can be understood that the behaviour of the average total cost curve depends on the behaviour of AFC and AVC curves. In the beginning, both AFC and AVC fall. So ATC curve falls. When AVC curve begins rising, AFC curve falls steeply ie fall in AFC is more than the rise in AVC. So ATC curve continues to fall. But as output increases further, there is a sharp increase in AVC, which is more than the fall in AFC. Hence ATC curve rises after a point. The ATC curve like AVC curve falls first, reaches the minimum value and then rises. Hence it has taken a U shape.

(iii) In the case of heavy good industry we all know that here fixed cost is higher than the variable cost. because in this type of industry initial investment should be high. lots of capital is needed. but return from this industry in short run(i.e less than 10 years) is comparatively low. so private investors are not interested in starting this type of industries. Rather they are interested in investing cosmatics and luxury good industry which require low investment but high profit. But a country will not be developed without establishing heavy good industries. Therefore Govt. take initiative to establish heavy good industries. Private investors are more likely to invest in those type of industries which require low investment but high profit.
