1 ) The long-run total expense curve plots the reduced total cost for each amount of output keeping input prices fixed. Basically, for a given set of input prices, the long-run total cost shape represents the overall cost linked to the solution to the long-run price minimization difficulty for each degree of output. When the price of one input improves, the isocost line for your level of total cost is going to rotate in toward the foundation. Assuming the isocost series was tangent to the isoquant for the firm's chosen level of end result, when the isocost line revolves it will no more touch the first isoquant. To ensure an isocost line to achieve a tangency with the unique isoquant, the firm would have to move to an isocost collection associated with higher level of00 of price, i. at the. an isocost line further more to the northeast. If the value of a solitary input goes up leaving other input rates the same as well as the level of end result constant, total cost can rise but by a small percentage compared to the increase in the input cost. This takes place because the organization will replacement away from the right now relatively more expensive labor to the now comparatively less expensive various other inputs. Therefore , if the price of labor rises by simply 20% keeping all other input prices continuous, total expense will rise by below 20%. If the prices of inputs rise by the same percentage, total cost is going to rise simply by exactly that same percentage. So , if input rates rise by simply 20%, total cost will likely rise simply by 20%. some. An increase in the price tag on labor would result in a long-run total cost curve that lies over a initial long-run total price curve at every quantity besides Q = 0. As AC sama dengan TC / Q, raising total price will increase average expense at every variety except Queen = zero. Therefore , the long-run average cost shape will move up.

a)
When MC > AC, common cost is elevating, and when MC < AC, average cost is decreasing. Therefore , if the typical cost curve is raising it must lay below the limited cost competition. If the marginal cost competition is raising, it may lay above or perhaps below the common cost curve. The only identifying factor the following is whether or not limited cost is situated above or perhaps below average price. If it lies above, typical cost will be increasing and

if it is situated below, common cost will probably be decreasing. Knowing that marginal value is increasing or decreasing tells us nothing regarding average cost. 6. TC MC AIR CONDITIONER
Q Once average cost is falling, little cost is going to lie below average cost, then when average expense is increasing, little cost is going to lie above average cost. Above the flat-bottomed portion where typical cost is nor increasing nor decreasing, minor cost and average expense will be equivalent. 7. The outcome elasticity of total expense, when basic can be created as
ε TC, Q =
MC AC
Seeing that AC = TC as well as Q, and since TC and Q should always be positive, ALTERNATING CURRENT will always be great. Marginal cost, MC, symbolizes the enhancements made on total expense associated with an increase in output. When ever output boosts, total price must always go up for a provided set of input prices, implying that MC is also always positive. Consequently , the output firmness of total cost should always be positive. almost eight. Because fixed cost will not change, minor costs reflect the change in variable costs. Thus, just like the relationship among any normal and limited, if average variable cost is decreasing, limited cost must be below average changing cost, of course, if average changing cost is increasing, marginal price must sit above average changing cost. This means marginal cost will meet average variable cost at the minimum of common variable cost. If the average variable price curve is flat, average variable expense is neither increasing nor...
