This same type of relationship can also be seen when examining marginal cost, though for different reasons. The law of diminishing returns states that as firms increase resources needed to ramp up production, marginal cost will decline, bottom out, then start to rise. To understand why, consider a car factory with 100 workers. Adding 25 more workers can help increase production and bring down the marginal cost of each new car. If the firm were to add another 100 workers, however, these employees would start to slow each other down, or get in each other's way, resulting in an increase in marginal cost.
From this example, one can see that as supply rises, price will also increase automatically. In a perfectly competitive market, firms will set production rates at the exact point where price equals marginal cost. By doing so, they are able to maximum profits and efficiency. Given that price is constantly fluctuating due to natural market forces, production rates, or supply, will continuously change as well. This relationship between marginal cost and supply holds at every price point, and continues to hold as price fluctuates.
In a market that it not perfectly competitive, this relationship between marginal cost and supply no longer holds true. For example, a firm that has a monopoly over the market does not have to respond to price changes because he is able to set prices for a product. In this type of market, the company determines production rates based on demand rather than marginal cost.
Therefore the marginal cost curve and the supply curve are the same thing. Oh, and reading your comment, you are correct in your example that the firm can recover their costs when the price is $2 by producing 3 units. Chapter 8 Pure Competition. At a profit-maximizing level of output of 25 units, a perfectly competitive firm's marginal revenue is $4, average variable cost is $.30, average total cost is $1.22 and marginal cost is $3.75 this firm's economic profit equal.
A perfectly competitive firm's supply curve is that portion ofits' marginal cost curve that lies above the minimum of the averagevariable cost curve. A perfectly competitive firm maximizes profitby producing the quantity of output that equates price and marginalcost. As such, the firm moves along it's marginal cost curve inresponse to alternative prices. Because the marginal cost curve ispositively sloped due to the law of diminishing marginal returns,the firm's supply curve is also positively sloped.

Why supply curve of a monopoly equals to its marginal cost curve?
How is a perfectly competitive firms marginal cost curve related to its supply curve?
a perfectly competitive firms supply curve will be the portion of the marginal cost curve which lies above the average variable cost curve (AVC)..this will be due to the firms unwillingness to supply below the price in which they could cover their variable costs Read More

A firm's marginal cost curve above the average variable cost curve is also?
Relationship between marginal cost and the supply curve for a purely competitive firm?
Marginal cost curve above the average variable cost curve, is the same as the short run supply curve. In perfect competition, MC=Price. It follows that production will be at that point. Hence the supply curve is the same as that part of the MC curve which is above AVC, where the firm can cover its variable cost....this is better than shutting down. Read More

6 If the average total cost curve is falling what is necessarily true of the marginal cost curve If the average total cost curve is rising what is necessarily true of the marginal cost curve?
When average total cost curve is falling it is necessarily above the marginal cost curve. If the average total cost curve is rising, it is necessarily below the marginal cost curve. Read More
What happens to marginal cost after the point where it equals average variable cost?
Marginal Cost will keep increasing (have upward slope) because of the principle of diminishing marginal returns. The MC curve above the its intersection with AVC is the Supply Curve *because below minimum AVC, the firms stops production) Read More
A purely competitive firm's short-run supply curve is?
Because of the price taking nature of the firm in the perfectly competitive market. The supply curve would be the portin of the (Marginal Cost Curve) that disects the (P=Ar=Mr curves). Som from that point up would be the supply curve, to produce below that point would not be beneficial to the establishment. Up sloping and equal to the portion of the marginal cost curve that lies above the average variable cost. The demand curve… Read More
Does monopolistically competitive firms have horizontal marginal cost curve?
No it does not. Only Perfectly Competitive firms have a horizontal Marginal Cost curve, which is also there demand curve. Read More
If marginal revenue is less than average revenue will the demand curve be downward sloping?
This question reflects a fundamental misunderstanding of supply and demand. Marginal revenue and average revenue are related to a firm's cost function, and are thus connected to SUPPLY. They have nothing to do with a demand curve in classical economics, which is the marginal benefit to the CONSUMER of being in the market. Read More

Is it possible for perfect competitive market to be inefficient?
It is possible for perfectly competitive markets to be inefficient when externalities are present. Externalities arise when an economic activity has an unintended impact on other economic agents and/or the market. This results in there being a socially optimal level of production that does not coincide with the privately determined equilibirum level of production derived from the supply and demand curves (which, respectively, represent the marginal private costs and marginal private benefits to producers and… Read More

Why the marginal cost curve always cut the average cost curve at its lowest point?
This is because if a marginal figure is less than an average figure, the new average figure will decrease. Read More
Why is the Marginal cost curve downward sloping?
Marginal cost curve is u-shaped curve, this is due to law of variable proportion(return to factors), firstly, there is an increasing return (i.e, decreasing cost) then there is a stage of constant returns (i.e, constant cost) then lastly comes the stage of decreasing returns (i.e increasing cost), that`s why marginal cost curve first slopes downward and then slope upward and become u-shaped.

Q3 Explain briefly the technique of marginal costing In what ways do you consider this?
The marginal cost of an additional unit of output is the cost of the additional inputs needed to produce that output. More formally, the marginal cost is the derivative of total production costs with respect to the level of output. Marginal cost and average cost can differ greatly. For example, suppose it costs $1000 to produce 100 units and $1020 to produce 101 units. The average cost per unit is $10, but the marginal cost… Read More
Does marginal cost curve always intersect the average cost curve at the average cost curve's lowest point?
When the marginal cost is below the average total costs or the average variable costs,then the AC would be declining.When marginal cost is above the average cost then the average cost would be increasing.Therefore the marginal cost should intersect with the average cost at the lowest point in order to pull the average cost upwards.

How a monopoly firm will not achieve allocative efficiency?
They produce at a different point than a competitive firm, a monopoly produces at a point where marginal revenue= marginal cost, where a competitive firm equates price to marginal cost. The marginal cost curve is lower than the demand curve, but the monopoly charges the price at the demand curve, which is a higher price and a lower quantity than a competitive market would produce.

Why is the Marginal cost curve U shaped?
Why AVC curve 'U' shaped?
Overall because of diminishing marginal returns. The marginal cost curve, MC, decreases until diminishing marginal returns set in and and it begins to increase. When the MC is below the AVC, the AVC must fall. When the MC is above the AVC, the AVC must rise. In otherwords, if the marginal cost is decreasing the average cost must be decreasing as well and vice versa. Read More

Is the area under the marginal cost curve equal to the total variable cost?
What happen to the marginal-cost curve when there is a reduction in business property taxes?
Why a firm supply curve will normally slop upwards from left to right?
The firm's supply curve generally is positively-sloped due to the law of supply, which states that as production increases, so does price. Mathematically, this relationship is a function of marginal cost, which is variable based on the type of good and market. However, more often than not, goods have increasing marginal costs as more units are produced, spiking price as more quickly as production approaches larger values. Read More

The demand curve for a monopolist differs from the demand curve faced by a competitive firm?
The pure monopolist's market situation differs from that of a competitive firm in that the monopolist's demand curve is downsloping, causing the marginal-revenue curve to lie below the demand curve. Like the competitive seller, the pure monopolist will maximize profit by equating marginal revenue and marginal cost. Barriers to entry may permit a monopolist to acquire economic profit even in the long run. Read More

Relationship between marginal social cost and marginal private cost?
The Marginal Social Cost (MSC) is the Marginal Private Cost (MPC) + the Marginal External Cost (MEC). As an example, a pulp and paper mill might produce paper using a supply curve of MPC = 4Q. The mill pumps its effluent into a river. The effluent then travels downstream and a village that gets its water form the river has to install purification systems. The installation of purification is an external cost borne by the… Read More
Why does the marginal cost curve cut through the average variable cost curve exactly at the minimum of the average variable cost curve?
Marginal cost curve cuts average cost (variable or total cost) at its minimum simply to portray the law of variable proportions. The idea is as labor is increased with capital being fixed, productivity increases upto a point and then decreases and later becomes negative. To relate the same productivity with average cost function, the average cost first decreases , reaches a minimum and then increases. Now marginal cost is just a change in the total… Read More
If a market generates a negative externality the social cost curve is above the supply curve true or false?
What is the relationship between marginal product and marginal cost?
The marginal product curve is 'n' shaped because of the law of diminishing returns. As you add more units of a variable factor, at first, the marginal product rises, (this is because the fixed factor is under-utilised, so adding more units of the variable factor will increase the output from each additional unit). But after a certain point, the marginal product begins to fall, as the fixed factor input becomes diluted amongst workers and so… Read More
What would cause a leftward shift in the supply curve for car washes?
A left-ward shift in the supply curve would be caused by an increase in its marginal cost, meaning that all units of car washing were strictly higher than before. Some examples might include: 1) increase cost of inputs (water, soap, etc.); 2) increase cost of operating capital (i.e.) machinery costs more to use than before); 3) increase in costs of maintenance for machinery and services.
