D. Calculate the total revenue for a firm which is selling 10 television sets at N21,000 each.

E. Total utility will decline only if _________ utility is negative.

F. What does the "non-satiation" expression connotes?

H. The Bertrand model is essentially the Cournot-Nash model except the strategic variable is price rather than _______

I. Any two points on an _________ curve generate the same level of utility.

J. Exchange value, on the other hand, is tied to how much someone is willing to pay for an ________ unit of the commodity.

K. The slope of the _________ curve measures the MRS.

L. Price discrimination is a pricing strategy that enables monopolist to charge customers __________ prices for the same good or service.

M. The theory of distribution is an attempt to explain how _________ is distributed among the of production.

N. Note that this (MR) too is equal to price, so the marginal revenue is constant as well, and is equal to average revenue.

O. Perfect competition means there are few, if any, ________ to entry for new companies, and prices are determined by supply and demand.

P. Since water is not very costly to acquire, people consume _______ water. At this high level of consumption, the marginal utility of an additional unit of water is relatively low.

Q. If TR/Q = (P x Q)/Q = Price, what is price?

R. Factors of production are never demanded for their own sake thus the demand here is a ________ demand

S. Monopolist ________ profits

T. Which of the following is an assumption of the model of perfect competition?

U. Expenditure on a particular good is the product of the amount of the good purchased times its price. We can then write the budget constraint as _____________.

V. Microeconomics also supposes that consumer consumers make their buying decisions in an effort to ___________ happiness or benefit.

W. Higher indifference curves are preferred to __________ ones, since more is preferred to less (non-satiation).

X. Consumer utility is achieved when the ratio of marginal utility of one commodity is equal to its price is equal to the _______ of another to its price.

Y. How did Adam Smith resolve the problem of low value for water and high value for diamond?

Z. If a good causes problem for a consumer we say it has _______ effect.

increased to 318. What is the
marginal revenue in this
situation?

AB. Perfect competition exists in an industry where perfect competition is characterized by ________ buyers and sellers, many products that are similar in nature and, as a result, many substitutes.

AC. When good X becomes relatively more expensive, the quantity of good X demanded falls as a result of the ________ effect

AD. The law of ________ marginal utility states that consumption of any item yields the consumer declining utility holding taste constant.

AE. Because the marginal utility of an additional diamond is higher than the marginal utility associated with an additional glass of water, diamonds have a _________ value in exchange.

AF. An example of price discrimination is quantity/bulk purchase _________

AG. These concepts of __________ and marginal utility can be used to resolve Adam Smith's diamond-water paradox.

AH. In a monopoly the company is similar to the ______

AI. The _______________ would then say that income is equal to the sum of consumer expenditure.

AJ. The demand curve facing a monopoly firm is the ___________ demand curve

AK. _________ utility is a measure of the additional utility that is derived when an additional unit of the good is consumed.

AL. These are few but very important features of monopolistic competition. Product ______ using branding and advertisement

AM. The short run profit maximization in monopolistically competitive firm is the same as that of monopoly i.e. ___________________ this condition should  hold.

A higher indifference curve that lies above and to the ________ of another indifference curve represents a higher level of satisfaction and combination on
a lower indifference curve yields a lower satisfaction.

AT. An oligopoly is where there are a __________ sellers with similar or identical products

AU. Monopolistic Competition is one of the markets in-between perfectly _________ market and monopoly market

AV. A basic assumption of microeconomics is that because a consumer does not have _______________, his or her available cash for spending must be judiciously allocated for maximum benefit.
