Answer:
The answer is in a perfect competition profit is maximized when marginal cost equal marginal revenue and price is equal to average revenue and marginal revenue, while in monopolist profit is maximized when marginal cost is equal to marginal revenue.
Explanation:
The firm in a perfectly competitive market is a price taker,the price in the market is determined by the market forces of demand and supply. The firm has to sell their product at the ruling market price.The demand curve facing the firm in perfectly competitive market is horizontal or perfectly elastic, profit is therefore maximized when the marginal cost is equal to average revenue and marginal revenue. The firm in the market operate at the output level in which the price and marginal revenue is equal to marginal cost. Whatever prices that change the market demand or supply will change the demand curve faced by the firm.The firm cannot do anything to this than to accept the market price and the demand curve.
In a monopoly the demand curve is identical to the demand curve of the firm, because industry demand curve is downward sloping.The monopolist can either set the price or quantity not the two.when one is determined the value of the other will be determined by the demand function. The profit maximization of the monopolist also requires that marginal cost must be equal to marginal revenue just like in the case of perfect completion.when the monopolist equates MR and MC the monopolist determines its output and the market price for the product. The revenue curve is steeper than the demand curve,because the straight line is the market demand. The firm will have to reduce The price of the product if they want to sell more of their product the unit of the product sold is the AR which is equal to the price.Therefore the AR curve of the monopolist and the perfect competition MR and AR are both identical that informed the reason why the marginal revenue curve is steeper than the demand curve for a single price monopolist.
Answer:
It illustrates that the classical model of the price level best applies to economies with persistently high inflation.
Explanation:
When a very low inflation rate has been constant in an economy, and the money supply increases suddenly, in the short run that change will not immediately increase the inflation rate, but instead it will increase real output.
Classical economists argue that an increase in the money supply will immediately affect the inflation rate, but that theory applies mostly to economies that have a certain level of inflation. For example, for the past 12 years, European nations have been experiencing very low inflation rates, sometimes even negative rates. But during that same period, the European Central Bank has carried on a huge expansionary policy. It favored economic growth, although not as much as expected, but it didn't skyrocket inflation rate as the classical economy model predicted.
Answer:
The contribution margin ratio can be calculated using either total amounts or per unit amounts.
Explanation:
Contribution margin ratio = 
This can even be done by 
This will calculate contribution as a percentage of Sales, with this margin ratio we get break even sales value, and not the units.
Whenever there is an increase in variable cost it decreases the contribution.
Therefore, correct statement is
The contribution margin ratio can be calculated using either total amounts or per unit amounts.
Answer:
Net foreign lending would be equal to <u>$4 billion</u>.
Explanation:
This can be computed using the formula for computing the total output of an open economy as follows:
Y = C + G + I + NX .................................. (1)
Where;
Y = Total Output = $35 billion
C = Desired consumption = $15 billion
G = Government purchases = $10 billion
I = Desired investment = $6 billion
NX = Net foreign lending = ?
Substituting the values into equation (1) and solve for NX, we have:
$35 = $15 + $10 + $6 + NX
$35 - $15 - $10 - $6 = NX
NX = $4 billion
Therefore, net foreign lending would be equal to <u>$4 billion</u>.
A price floor is the mining price that can be charged for an item. A binding price floor is a price set above market average pricing. Since the government regulates this and will not let them sell below the average market price, the price is set in stone for the products price in the market.
