What is the shape of the marginal-revenue curve if the total-revenue curve is a positively sloped straight line?
it will be parallel to horizantal axis
Why is the marginal revenue curve below the demand curve and why does the vertical distance between them diverge as output increases?
The demand curve is a tremendously useful illustration for those who can read it. We have seen that the downward slope tells us that there is an inverse relationship between price and quantity. One can also view the demand curve as separating a region in which sellers can operate from a region forbidden to them. But there is more, especially when one considers what an area on the graph represents. If people will buy 100 units of a product when its price is $10.00, as the picture below illustrates, total revenue for sellers will be $1000. Simple geometry tells us that the area of the rectangle formed under the demand curve in the picture is found by multiplying the height of the rectangle by its width. Because the height is price and the width is quantity, and since price multiplied by quantity is total revenue, the area is total revenue. The fact that area on supply and demand graphs measures total revenue (or total expenditure by buyers, which is the same thing from another viewpoint) is a key idea used repeatedly in microeconomics. From the demand curve, we can obtain total revenue. From total revenue, we can obtain another key concept: marginal revenue. Marginal revenue is the additional revenue added by an additional unit of output, or in terms of a formula: Marginal Revenue = (Change in total revenue) divided by (Change in sales) According to the picture, people will not buy more than 100 units at a price of $10.00. To sell more, price must drop. Suppose that to sell the 101st unit, the price must drop to $9.95. What will the marginal revenue of the 101st unit be? Or, in other words, by how much will total revenue increase when the 101st unit is sold? There is a temptation to answer this question by replying, "$9.95." A little arithmetic shows that this answer is incorrect. Total revenue when 100 are sold is $1000. When 101 are sold, total revenue is (101) x ($9.95) = $1004.95. The marginal revenue of the 101st unit is only $4.95. To see why the marginal revenue is less than price, one must understand the importance of the downward-sloping demand curve. To sell another unit, sellers must lower price on all units. They received an extra $9.95 for the 101st unit, but they lost $.05 on the 100 that they were previously selling. So the net increase in revenue was the $9.95 minus the $5.00, or $4.95. There is a another way to see why marginal revenue will be less than price when a demand curve slopes downward. Price is average revenue. If the firm sells 100 for $10.00, the average revenue for each unit is $10.00. But as sellers sell more, the average revenue (or price) drops, and this can only happen if the marginal revenue is below price, pulling the average down. The reasoning of why marginal will be below average if average is dropping can perhaps be better seen in another example. Suppose that the average age of 20 people in a room is 25 years, and that another person enters the room. If the average age of the people rises as a result, the extra person must be older than 25. If the average age drops, the extra person must be younger than 25. If the added person is exactly 25, then the average age will not change. Whenever an average is rising, its marginal must be above the average, and whenever an average is falling, its marginal must be below the average. If one knows marginal revenue, one can tell what happens to total revenue if sales change. If selling another unit increases total revenue, the marginal revenue must be greater than zero. If marginal revenue is less than zero, then selling another unit takes away from total revenue. If marginal revenue is zero, than selling another does not change total revenue. This relationship exists because marginal revenue measures the slope of the total revenue curve. The picture above illustrates the relationship between total revenue and marginal revenue. The total revenue curve will be zero when nothing is sold and zero again when a great deal is sold at a zero price. Thus, it has the shape of an inverted U. The slope of any curve is defined as the rise over the run. The rise for the total revenue curve is the change in total revenue, and the run is the change in output. Therefore, Slope of Total Revenue Curve = (Change in total revenue) / (Change in amount sold) But this definition of slope is identical to the definition of marginal revenue, which demonstrates that marginal revenue is the slope of the total revenue curve.
What factors determine the shape of the marginal social benefit curve in a market economy?
The shape of the marginal social benefit curve in a market economy is determined by factors such as consumer preferences, externalities, government regulations, and the availability of substitutes.
Why is Production Possibility Curve concave to the origin?
I have never heard that the demand curve must be concave. In fact, it is most often modeled as either linear or convex. Common convex specifications include log-linear and constant-elasticity demand functions. A number of empirical papers attempt to estimate the shape of the demand curve for specific products but I am not familiar with anyone concluding that demand is concave generally.
Why avc curve U shape?
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.

Is a lenses in glasses concave or convex?
Lenses can be concave or convex depending on their shape. Concave lenses curve inward and are thinner in the center, causing light to diverge. Convex lenses curve outward and are thicker in the center, causing light to converge. Glasses can have either concave or convex lenses, depending on what vision correction is needed.
What is the difference between concave and convex shapes and how can they be distinguished from each other?
Concave shapes curve inward, like a cave, while convex shapes curve outward. To distinguish between them, you can look at the direction in which the shape curves - concave curves inwards, while convex curves outwards.
Is concave mirror in shape of parabola?
no concave mirror is in shape of concave mirror
How does PPC graph of unemployment looks like?
There is no shift in the PPC.Only a dot is marked within the curve(Not on the curve) in the exact center of the two axes.The shape of the PPC is concave to the origin.
What does 'concave up' mean in physics terms?
In physics, 'concave up' refers to the shape of a curve or surface that opens upward, resembling a cup that faces upwards. This typically signifies a region where the rate of change of a function is increasing. It is often associated with the idea of a positive second derivative.

Why avc curve U shape?
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.
Why is product possibility curve linear?
The production possibility curve is not always linear, in fact, it is usually concave down (bowed-in). The shape of the curve depends on the substutability of the goods described by the curve in the question. When goods are perfectly substitutable in production, the PPP (or PPF) is linear.
Why does a production possibilities curve have a bowed-out shape?
The PPF is bowed outwards (concave to the origin) as tradeoffs between the production of any two goods are constant.
