Q

Why is PPC downward slope?

A

Represents trade-offs
- producing more of one good will shift resources away from the production of another good

A
  • value of the NEXT best alternative

Q

Why is PPC bowed out?

A

More of one good means that opportunity cost is increasing ** (fact check)

-different uses of resources to produce 2 different resources

25
Expectation of an increase in future prices
supply will decrease (producers will try to save supply to sell later)
26
Decrease in factors of production prices causes the supply to...
increase
27
Shifts a long the supply curve
28
Equilibrium Price
price when quantities demanded and supplied are equal
29
Surplus (AD/AS)
Quantity supplied is GREATER than Quantity demanded Qs>Qd Price level is more than equillibrium Producers are motivated to lower prices in order to eliminate surplus
30
Shortage (AD/AS)
Quantity Demanded is GREATER than Quantity Supplied Qd>Qs Price level under equilibrium, so prices of good rises
31
Changes in Equilibrium Supply increases
- Price decreases - Quantity increases NOTE: There will be a surplus , price must fall until Quantity demanded and Quantity supplied are EQUAL
32
Changes in Equilibrium Supply decreases Demand increases
Price INCREASES Quantity is unknown (what is degree of shifts in demand/supply?)
33
Price of a factor of production DECREASES
- supply increases (so that would mean price decreases)
34
How to find Equilibrium
Find price and quantity associated with intersection **
35
Changes in Equilibrium Demand and Supply Increases
- Price is undetermined - Quantity increases
36
When income increases the DEMAND of a inferior good... (price and quantity)
Demand of good will DECREASE - price and quantity will DECREASE
37
When Demand changes what is price and quantity relationship?
- positive relationship - both will move same direction
38
What happened to lead PRICE increase and QUANTITY decrease when SUPPLY DECREASES
supply decreases will result a shortage, (Qs < Qd) at the previous price.
39
What happens to the PRICE and QUANTITY if Demand INCREASES and Supply DECREASES?
Price increases Quantity is undetermined - Supply decreases the price level goes up and quantity goes down - Demand increases (price and quantity increase) Quantity is opposite, we do not know what is going to happen
40
Changes in Equilibrium Increase in demand?
Both price and quantity increase
41
What happens when there is a change of price to a complimentary good?
Change in price of complimentary good effects DEMAND **
42
FACTORS OF PRODUCTION
Land - minerals & natural res. Labor - humans working Capital - tools, factories, equipment Entrepreneurship - ability to manage a business ALL THESE HELP INPUT TO MAKE **
43
Agent
a decision made by (person or group)
44
Incentives
rewards or punishments followed after action (An agent bases decision on incentives)
45
Economic Aggregates
-measuring the economic performance of an economy - a summary of all markets (unemployment rate, inflation rate, etc)
46
Capital
tools machinery or things that are already made to produce things
47
Efficiency (where on PPC?)
the full employment of resources in production. -efficient combinations of output (will be directly on PPC {the curve})
48
Inefficient use (where on PPC)
under-utilization of resources underemployment of any of the factors of production (land, labor, capital, entrepreneur) not so good combinations of production (inside of the curve of the PPC)
49
Growth in PPC (where on PPC)
increase in economy's ability to produce goods and services OVER TIME (a shift OUT [-->] of PPC)
50
Contraction in PPC (where on PPC)
decrease in output {under-utilization of resources} (point is further away** and interior of PPC)
51
Constant Opportunity costs (on PPC)
(straight line) opportunity cost of good remains constant as output of good increases
52
Increasing opportunity costs ( on PPC)
opportunity cost of good increases as output of the good increases (PPC is bowed out from origin)
53
productivity (where on PPC)
ability to combine economic resources. - an increase in productivity causes economic growth even with resources being the same - (shift out of PPC)
54
what happens if a point is outside of PPC
its impossible
55
Opportunity Cost EQUATION
opportunity cost of each unit of good X = (Y1 - Y2) / (X1 - X2) units of good Y
56
Demand
all the quantity of good or service a buyer WOULD BUY AT ALL PRICES ( the whole demand curve )
57
law of demand (why demand curve is downward)
there is a inverse relationship between good's price and quantity consumers demand. PRICE goes DOWN People BUY MORE
58
change in quantity demanded
every point on the demand curve is quantity demanded (amount buyers are willing to purchase at price) > MOVEMENT ALONG THE DEMAND CURVE - change of price causes movement on same curve
59
change in demand
buyers are willing to buy A DIFFERENT quantity at all possible prices - shift in demand curve - change in the determinants of demand
60
determinants of demand
causes demand curve to shift TONIE Tastes Other goods Number of buyers Income Expectations
61
Normal good
buyers will demand more of this good when their incomes increase
62
Inferior good
buyers will demand when their incomes decrease
63
Substitute good
goods that replace each other when price of good increases the demand for its substitute will increase
64
Complement good
goods that are bros consumed together when price of a good increases the demand for its complement decrease
65
Supply
curve showing all the possible quantities that sellers are WILLING and ABLE to produce
66
Law of Supply
direct relationship between goods price and quantity supplied - price increases, quantity increases and vice versa -upward sloping
67
Change in quantity supplied
the quantity supplied or what sellers are willing to SELL at a specific price, MOVEMENT ALONG SUPPLY CURVE from change in good's price
68
change in supply
a movement or shift in an ENTIRE SUPPLY CURVE from a NON PRICE DETERMINANTS
69
Determinants of supply (6)
non price factors that SHIFT THE SUPPLY CURVE - number of sellers - level of technology - prices of inputs used to produce good - amount of government regulation - price of other goods sellers could produce - expectations among producers of future prices
70
Changes in Equilibrium Supply Decreases
Price increases Quantity decreases
71
Changes in Equilibrium Demand decreases
BOTH Price and Quantity decreases
72
Changes in Equilibrium Demand decreases and supply increases
price decreases quantity is undetermined **
73
Changes in Equilibrium Demand and Supply decrease
Price is undetermined Quantity decreases **
