Q

Principle #10: Society faces a short-run tradeoff between inflation and unemployment

A

-Increasing the amount of money stimulates the overall level of spending and thus the demand for goods and services -Higher demand may, over time, cause firms to raise their prices, but in the meantime, it also encourages them to increase the quantity of goods and services they produce and to hire more workers to produce those goods and services. -More hiring means lower unemployment

Q

Positive Statements:

A

Descriptive statements. They make claims about how the world is.

31
Q

Normative Statements:

A

Prescriptive statements. They make claims about how the world should be.

32
Q

Absolute Advantage:

A

Comparison of the productivity of one person, firm or nation to that of another

33
Q

Comparative Advantage:

A

Description of the opportunity cost of two producers

34
Q

Comparative Advantage:

A

Description of the opportunity cost of two producers

35
Q

Market:

A

A group of buyers and sellers of a particular good or sevice

36
Q

Competitive Market:

A

A market in which there are so many buyers and so many sellers that each has a negligible impact on the market price

37
Q

Quantity Demanded:

A

The amount of the good that buyers are willing and able to purchase

38
Q

Law of Demand:

A

All other things being equal, when the price of a good rises, the quantity demanded of the good falls and when the price falls, the quantity demanded rises.

39
Q

Demand Schedule:

A

A table that shows the relationship between the price of a good and the quantity demanded

40
Q

Normal Good:

A

A good that when income falls, demand falls

41
Q

Inferior Good:

A

A good that when income falls, demand increases

42
Q

Substitues:

A

Two goods for which an increase in the price of one leads to an increase in the demand for the other

43
Q

Complements:

A

Two goods for which an increase in the price of one leads to a decrease in the demand for the other

44
Q

Curve Shifts

A

A curve shifts when there is a change in a relevant variable that is not measured on either axis. Because price is on the vertical axis, a change in price represents a movement ALONG the demand curve. By contrast, income, the prices of related goods, tastes, expectations, and the number of buyers are not measure on either axis, so a change in one of these variables shifts the demand curve.

45
Q

Quantity Supplied:

A

Any good or service that sellers are willing and able to sell.

46
Q

Law of Supply:

A

All other things being equal, when the price of a good rises, the quantity supplied of the good also rises, and when the price falls, the quantity supplied falls as well

47
Q

Supply Schedule:

A

A table that shows the relationship between the price of a good and the quantity supplied

48
Q

Equilibrium:

A

The point at which the supply and demand curves intersect

49
Q

Equilibrium Price:

A

The price at the equilibrium

50
Q

Equilibrium Quantity:

A

The quantity at the equilibrium

51
Q

Surplus:

A

A situation in which quantity supplied is greater than quantity demanded

52
Q

Shortage:

A

A situation in which quantity demanded is greater than quantity supplied

53
Q

The Law of Supply and Demand:

A

The price of any good adjusts to bring the quantity supplied and quantity demanded for that good into balance

54
Q

Elasticity:

A

A measure of the responsiveness of quantity demanded or quantity supplied to one of its determinants

55
Q

Price Elasticity of Demand:

A

A measure of how much the quantity demanded of a good responds to a change in the price of that good.

Computed:

Price Elasticity of D = % ^ in QD

% ^ in P

56
Q

Demand is Elastic when the elasticity is…..

Demand is Inelastic when the elasticity is…..

A

Demand is Elastic when the elasticity is greater than 1

Demand is Inelastic when the elasticity is less than 1

57
Q

Total Surplus:

A

The total surplus of a market is the net gain to consumers and producers trading in the market. It is the sum of producer surplus and consumer surplus (or the size of the economic pie).

58
Q

Consumer Surplus:

A

The net gain to buyers. It is the difference between the buyer’s willingness to pay (Demand curve) and the price paid for it (Price), summed over the quantity consumed (Quantity).

59
Q

Producer Surplus:

A

The net gain to sellers. It is the difference between the price received (Price) and the sellers’ cost (Supply curve), summed over the quantity produced (Quantity).

60
Q

Deadweight Loss:

A

The decrease in total surplus that results from an inefficient underproduction or overproduction. The extra cost in the form of inefficiency because (government involvement) discourages mutually beneficial transactions.

61
Q

Price Elasticity of Demand Determinants

A

Time Horizon

Availability of Substitutes

Necessity vs Luxuries

Definition of the Market

62
Q

Price Elasticity of Demand

Time Horizon

A

Goods tend to have more elastic demand of longer time horizons

Short time = Inelastic

Long time = Elastic

63
Q

Price Elasticity of Demand

Availibility of Substitutes

A

Goods with close substitutes tend to have more elastic demand because it is easier for consumers to switch from that good to others.

W/ Substitutes = Elastic

W/out = Inelastic

64
Q

Price Elasticity of Demand

Necessity vs Luxury

A

Necessity = Inelastic

Luxury = Elastic

65
Q

Price Elasticity of Demand

Definition of the Market

A

Narrow defined market = Elastic

Broadly defined market = Inelastic

Narrowly defined markets are more elastic because it is easier to find substitutes for a good. ie Food is broad and there isnt a sub. for food. Ice Cream is narrow, there are many subs for ice cream.

66
Q

Total revenue equation:

A

Price x Quantity Sold

67
Q

Income Elasticity of Demand

A

A measure of how the quantity demanded changes as consumer income changes.

Calculated:

Income elasticity of demand = % ^ QD

% ^ Income

68
Q

IRT: Income elasticity of demand

Normal Goods:

A

Normal goods have positive income elasticities.

69
Q

IRT: Income elasticity of demand

Inferior Goods:

A

Inferior Goods have negative income elasticity

70
Q

Cross-Price Elasticit of Demand

A

A measure of how the quantity demanded of one good changes as the price of another good changes.

Calculated:

Cross-Price elasticity of demand = % ^ in QD of Good 1

% ^ in P of Good 2

71
Q

What does Cross-Price Elasticy of Demand tell us

A

Whether two goods are substitutes of complements.

Substitutes have positive cross-price elasticity

Complements have negative cross-price elasticity

72
Q

Price Elasticity of Supply

A

A measure of how much the quantity supplied responds to changes in price.

Computed:

Price elasticity of Supply = % ^ QS

% ^ P

73
Q

Price Elasticity of Supply Determinants

A

Time - More time = Elastic. Suppliers can make factories to increase the QS. Responds substantially to price changes.

Short run = Inelastic. Suppliers cannot increase the factories making goods overnight. Does not respond to price changes very much
