According to the rationality assumption, people: Use rules of thumb to make choices. Can never consider each of the most relevant alternatives. Do not ever take into account the interests or well-being of others. Do not intentionally make decisions that would leave them worse off.
Do not intentionally make decisions that would leave them worse off.
Equilibrium in a competitive
Equilibrium in a competitive market results in the economically efficient level of output, where marginal benefit equals marginal cost.
Complements
Goods and services that are used together. When two goods are complements, the more consumers buy of one, the more they will buy of the other. A decrease in the price of a complement causes the demand curve for a good to shift to the right. An increase in the price of a complement causes the demand curve for a good to shift to the left.
Change in Demand vs. Change in Quantity Demanded
It is important to understand the difference between a change in demand and a change in quantity demanded. A change in demand refers to a shift of the demand curve. A shift occurs if there is a change in one of the variables, other than the price of the product, that affects the willingness of consumers to buy the product. A change in quantity demanded refers to a movement along the demand curve as a result of a change in the product's price.
When you think of an arrangement or institution that brings buyers and sellers of a good or service together, what are you thinking of?
Market
Consumer surplus
The difference between the highest price a consumer is willing to pay for a good or service and the price the consumer actually pays. measures the benefit to consumers from participating in a market, and producer surplus measures the benefit to producers from participating in a market. Consumer surplus in a market is equal to the total benefit received by consumers minus the total amount they must pay to buy the good.
Import
are goods and services bought domestically but produced in other countries.
Export
are goods and services produced domestically but sold to other countries.
Tangible products like cars and televisions are referred to as __________. goods services
goods
tariff
is a tax imposed by a government on imports of a good into a country.
Free trade
or trade between countries that is without government restrictions, makes consumers better off
Normal good
A good for which the demand increases as income rises and decreases as income falls. A "normal good" is a good where, when an individual's income rises, they buy more of that good.
Price ceiling
A legally determined maximum price that sellers may charge.
Black market
A market in which buying and selling take place at prices that violate government price regulations.
Economic efficiency
A market outcome in which the marginal benefit to consumers of the last unit produced is equal to its marginal cost of production and in which the sum of consumer surplus and producer surplus is at a maximum.
Perfectly competitive market
A market that meets the conditions of (1) many buyers and sellers, (2) all firms selling identical products, and (3) no barriers to new firms entering the market.
A black market is A. a market in which all transactions involve activities (such illicit drugs, prostitution, etc.) many in the population find morally offensive. B. very similar to a "gray" market except that the goods and services exchanged are imported. C. a market in which buying and selling take place at prices that violate government price regulations. D. a market in which buying and selling take place at prices consistent with government price regulations.
C
Consider the following statement: "An increase in supply decreases the equilibrium price. The decrease in price increases demand." The statement is A. false: increases in supply decrease price. B. true: increases in supply decrease price. Decreases in price increase demand. C. false: decreases in price affect the quantity demanded, not demand. D. false: increases in supply increase price. Decreases in price increase demand.
C
Economic surplus in a market is the sum of _____ surplus and _____ surplus. In a competitive market, with many buyers and sellers and no government restrictions, economic surplus is at a _____ when the market is in _____. A. consumer; producer; maximum; disequilibrium B. consumer; producer; minimum; equilibrium C. consumer; producer; maximum; equilibrium. D. consumer; government; maximum; equilibrium
C
The distinction between a normal and an inferior good is A. when income increases, demand for a normal good decreases while demand for an inferior good increases. B. normal goods are used for the same purposes while inferior goods are used together. C. normal goods are used together while inferior goods are used for the same purposes. D. when income increases, demand for a normal good increases while demand for an inferior good falls.
D
Who is harmed when individual nations move from autarky to free trade? A. The nation taken as a whole. B. The domestic customers of the firms that went out of business. C. The foreign customers of the firms that now specialize. D. The owners of the firms that went out of business.

Deadweight loss is the reduction in economic surplus resulting from a market not being in competitive equilibrium. In the diagram to the right, deadweight loss is equal to the area(s): A. B & D. B. A, B, & C. C. A. D. C & E.
D Consider the situation in which the price (P1) of a product is above the equilibrium price, as shown in the diagram above. At competitive equilibrium, consumer surplus is equal to the sum of areas A, B, and C. At the higher price, fewer units are sold, so consumer surplus declines to just the area of A. At competitive equilibrium, producer surplus is equal to the sum of areas D and E. At the higher price of P1, producer surplus changes to be equal to the sum of areas B and D. \Notice that this is less than the original economic surplus by an amount equal to areas C and E. The reduction in economic surplus resulting from a market not being in competitive equilibrium is called the deadweight loss.
Substitutes
Goods and services that can be used for the same purpose. When two goods are substitutes, the more you buy of one, the less you will buy of the other. A decrease in the price of a substitute causes the demand curve for a good to shift to the left. An increase in the price of a substitute causes the demand curve for a good to shift to the right.
If demand increases by more than supply, the equilibrium price rises. If demand increases by less than supply, the equilibrium price falls.
If demand increases by more than supply, the equilibrium price rises. If demand increases by less than supply, the equilibrium price falls.
Quantity Supplied
If only the price of the product changes, there is a movement along the supply curve, which is an increase or a decrease in the quantity supplied.
Producer surplus
The difference between the lowest price a firm would be willing to accept for a good or service and the price it actually receives. Producer surplus in a market is equal to the total amount firms receive from consumers minus the cost of producing the good. In a sense, then, consumer surplus and producer surplus measure the net benefit to consumers and producers from participating in a market rather than the total benefit.
Main purpose of quota and most tariffs
The main purpose of most tariffs and quotas is to reduce the foreign competition that domestic firms face.
Law of supply
The rule that, holding everything else constant, increases in price cause increases in the quantity supplied, and decreases in price cause decreases in the quantity supplied. There is a positive relationship between price and quantity supplied. Therefore, the supply curve slopes upward. A change in quantity supplied is shown as a movement along the supply curve from one point to another.
normative analysis

Comparative advantage
is the ability of an individual, a firm, or a country to produce a good or service at a lower opportunity cost than competitors.
We do not see complete specialization in the real world for three main reasons:
1. Not all goods and services are traded internationally. 2. Production of most goods involves increasing opportunity costs. 3. Tastes for products differ.

Law of Demand
The rule that, holding everything else constant, when the price of a product falls, the quantity demanded of the product will increase, and when the price of a product rises, the quantity demanded of the product will decrease. That is, there is an inverse relationship between price and quantity demanded. This is shown as a movement along the demand curve from any point to another.
Economic surplus
The sum of consumer surplus and producer surplus
price cieling
To affect the market outcome, a price ceiling must be set below the equilibrium price. Otherwise, the price ceiling will not be binding on buyers and sellers.
Economics:
is concerned with how people respond to incentives
Economists believe that an individual or firm should continue any activity until: marginal benefit is greater than marginal cost. marginal benefit is equal to marginal cost. marginal benefit is less than marginal cost.
marginal benefit is equal to marginal cost . Continuing to engage in the activity when marginal benefit exceeds marginal cost will increase the total benefit of the activity. Conversely, continuing to engage in the activity when marginal benefit is less than marginal cost will reduce the total benefit of the activity. For this reason, the point where you should cease the activity is where marginal benefit is equal to marginal cost.
As illustrated in the diagram to the right, when a nation moves from autarky to free trade, economic surplus increases by the areas represented by A. C and D. B. A, B, C and D. C. B and E. D. B, C and D.
A Under autarky, consumer surplus would be area A in the above diagram. With imports, the reduction in price increases consumer surplus, so it is now equal to the sum of areas A, B, C, and D. Although the lower price increases consumer surplus, it reduces producer surplus. Under autarky, producer surplus was equal to the sum of the areas B and E. With imports, producer surplus is equal to only area E. Recall that economic surplus equals the sum of consumer surplus and producer surplus. Moving from autarky to allowing imports increases economic surplus in the United States by an amount equal to the sum of areas C and D.
In general, the term "ceteris paribus" means A. all else equal. B. holding everything else variable. C. unsettled mathematical paradigms. D. Both A and B
A Ceteris paribus ("all else equal") condition The requirement that when analyzing the relationship between two variables—such as price and quantity demanded—other variables must be held constant.
