Then its variable cost function is Q 3 –5Q 2 +60Q, and its average variable cost function is (Q 3 –5Q 2 +60Q)/Q= Q 2 –5Q + 60. The slope of the average variable cost curve is the derivative of the latter, namely 2Q – 5. Equating this to zero to find the minimum gives Q = 2.5, at which level of output average variable cost is 53.75.
The more variable costs used to increase production (and hence more total costs since TC=FC+VC), the more output generated. Marginal costs are the cost of producing one more unit of output. It is an increasing function due to the law of diminishing returns , which explains that is it more costly (in terms of labour and equipment) to produce ...
Average variable cost plus average fixed cost equals average total cost (ATC): + =. A firm would choose to shut down if the price of its output is below average variable cost at the profit-maximizing level of output (or, more generally if it sells at multiple prices, its average revenue is less than AVC).
At a level of Q at which the MC curve is above the average total cost or average variable cost curve, the latter curve is rising. [10]: 212 If MC is below average total cost or average variable cost, then the latter curve is falling. If MC equals average total cost, then average total cost is at its minimum value. If MC equals average variable ...
If for years 1 and 2 (possibly a span of 20 years apart), the nominal wage and price level P of goods are respectively nominal wage rate: $10 in year 1 and $16 in year 2 price level: 1.00 in year 1 and 1.333 in year 2, then real wages using year 1 as the base year are respectively: $10 (= $10/1.00) in year 1 and $12 (= $16/1.333) in year 2.
Therefore, increased competition reduces price and cost to the minimum of the long run average costs. At this point, price equals both the marginal cost and the average total cost for each good production. [7] [8] Once this has occurred a perfect competition exists and economic profit is no longer available. [12] When this occurs, economic ...
For example, in the IS-LM graph shown here, the IS curve shows the amount of the dependent variable spending (Y) as a function of the independent variable the interest rate (i), while the LM curve shows the value of the dependent variable, the interest rate, that equilibrates the money market as a function of the independent variable income ...
If the firm knows average total cost and average variable cost, it is possible to find the same result as Example 1. Because average total cost is average variable cost plus average fixed cost, average fixed cost is average total cost minus average variable cost. [2] If producing 5 shirts generates an average total cost of 11 dollars and ...
