Q

what is the law of increasing opportunity cost

A

as the production of one good increases, the opportunity cost of producing additional units of that good also increases.

because resources are not perfectly adaptable

Q

where is productive efficiency and where is productive inefficiency on a PPF

A

any point on the curve is productively efficient
(using all factors of production to there maximum levels)
Any point inside the curve is productively inefficient(unemployment on macro)
Any point outside of the curve is unattainable with the given factors of production

Q

what is Pareto efficiency and where is it on a PPF

A
  • the idea that you cannot make someone better off without making someone else worse off
  • Pareto efficiency is on any point on the curve as if you change the ratio of production you are making people who like the foregone product worse off

Q

how do you shift the PPF curve

A

-increase/decrease the quality and or quantity of factors of production (Q^2CELL)
-The shift could also favour one product more than the other and so the curve would shift more on one side than the other

Q

What is the income effect
Don’t know about this one styl ?????

A

As prices go up our incomes can’t stretch as far and therefore we are less ABLE to buy as we can’t afford the same quantity of goods as before and demand contracts because of this
vice versa for a lowering of price

A

> 1 demand is price elastic
<1 demand is price inelastic

∞ is perfectly price elastic
1 is unit price elastic

55
Q

what does price inelastic and elastic actually mean

A

-if demand for a good is price elastic, then a percentage change in price will bring about an even larger percentage change in quantity demanded.
-if demand for a good is price inelastic, then a percentage change in price will bring about a smaller change in quantity demanded

56
Q

what does a elastic and inelastic demand curve look like

A

inelastic are much steeper whereas elastic have a more gentle gradient

57
Q

what determines a good/services PED elasticity

A

Substitutes, more subs more price elastic
Percentage of income ( that a price change takes), more it takes the more price elastic
Luxurys/necessity (luxurys are more price elastic whereas necessitys are more price inelastic)
Addictive/habit forming (more price inelastic)
Time period, in the short run demand is price inelastic because there are few subs available. In the long run demand is more pirce elastic as more subs become available

58
Q

what rhyming tool can be used to estimate how a change in price would affect total revenue for demand elastic and inelastic goods/services

A

elastic only iritates skin
elastic
opposite
inelastic
same

Increase in price of elastic good would reduce rev
Increase in inelastic good increase in rev

59
Q

what happens to total revenue if a price elastic good/service has an increase in price

A

elastic opposite, there would be a decrease in total revenue as the quantity demanded for the good drops dramatically

Vice versa if u decrease price

60
Q

what happens to total revenue if a price inelastic good/servie has a increase in price

A

Inelastic same, there would be a increase in total revenue as the Qd falls but only by a small amount

Vice versa if there is a decrease in price

61
Q

what is the formula for PES

A

%∆Qs/%∆Price

62
Q

what does PES measure

A

measures the responsiveness of quantity supplied to a change in price

63
Q

what do the values of PES tell us

A

> 1 supply is price elastic
<1 supply is price inelastic
0 supply is price in perfectly inelastic
∞ supply is perfectly price elastic
1 supply is perfectly unit price elastic

64
Q

what is unique about the values you get from PES

A

They are always positive, due to the law of supply

65
Q

what determines a good/service PES

A

Production lag( the longer the production lag the more supply inelastic)
Stocks( the larger the level of stocks the more price elastic)
Spare capacity (The more spare capacity the more price elastic supply is)
Substituteability of FOPs (The more substituteable the more price elastic supply is)
Time (In the short run supply is more price inelastic, in the long run supply is more price elastic)
^in the short run there is at least 1 fixed FOP usally 2 land and capital so is not as easy to change Qs, Long run all factors are variable and so is easier to change Qs

66
Q

what does XED measure

A

Measures the responsiveness of Qd of a good/service given a change in price of another good/service

67
Q

what is the formula for XED

A

%∆Qd(a) / %∆P(b)

A & B are products

68
Q

what do postitive and negative XED results show

A

if the answer to the calculation is positive then the products are substitues
If the answer to the calculation is negative then the products are compliments

Party Season Near Christmas. Positive substitute negative compliment

69
Q

What do the numerical values of XED tell us

A

> 1 Demand between the goods is price elastic (strongly related)
<1 Demand between the goods is price inelastic (weakly related)
0 demand between the goods is perfectly price inelastic ( no relationship)

70
Q

what would go on the x and y axis on a XED diagram

A

on the y axis put the price of one good
on the x axis put the change in demand of the other good

71
Q

which way would the demand curves slope on a compliment/substiute XED graph

A

On a compliment XED graph the demand curve would slope Downwards (like a normal demand curve)
On a substitute XED graph the demand curve would slope upwards (like a supply curve)

72
Q

What does YED measure

A

YED measures the responsivenes of the Qd given a change in income

73
Q

what is the formula for YED

A

%∆Qd / %∆Y

Y = income

74
Q

what do positive and negative YED results tell us

A

a positive result is a normal good
a negative result is a inferior good

75
Q

what do different positive YED values tell us

A
  • positive value = normal good
  • greater than 1 demand is income elastic (luxury)
  • less than 1 demand is income inelastic (neseccity)
  • 0 is perfectly income inelastic
76
Q

What do negative YED values tell us

A
  • negative value = inferiour good
  • greater than -1 demand is income elastic
  • less than -1 demand is income inelastic
  • -0 demand is perfectly income inelastic
77
Q

what is a normal good

A

good that sees an increase in demand as incomes rise

vice versa

78
Q

what is a luxury good

A

a good with elastic YED more than 1/-1

vice versa

79
Q

What is a inferior good

A

as incomes rise demand for good falls

vice versa

80
Q

how can PED be used by businessess

A
  • pricing descions for total revenue (if good elastic, should drop price to raise total rev)
  • employment, stocks and supply (if good elastic and want to lower price should increase supply which needs more labour)
  • needed for price discrimination
81
Q

How is PES important for businesses

A
  • bussinesses want supply as price elastic as possible, so they can change their supply more quickly following a change in price
  • if they know their supply is price inelastic they want to increase their elasticity
82
Q

How can XED be used by firms

A
  • helps with pricing desicions
  • helps make non-price competative desicions
  • important for employment, stocks and supply
    ^ if your rival dropping prices and you cant follow u have to be prepared for a decrease in revenue
83
Q

how is YED important for a business

A
  • important for pricing desicions
  • tells you type of good you produce (normal,luxury, inferior)
  • helps you plan for recessions and booms (as incomes fluctuates)
  • employment, stock and supply purposes
84
Q

What are some limitations to elasticitys

A
  • values only estimates of what could happen (data could be faulty)
  • cetris paribus is assumed
  • PED varies along the demand curve (firms cannot keep changing prices and expect too see the same impact on Qd)
85
Q

what are indirect taxes a form of

A

Goverment intervention

86
Q

what are the 2 main reasoon why indirect taxes are used

90
Q

What are the types of indirect taxes

A

Specific and ad valoram

91
Q

what is a specific indirect tax

A

a tax per unit (e.g. wine duty or alcohol duty)

92
Q

what does the vertical distance between the supply curves on a specific indirect tax diagram represent

A

It represents the value of the tax

93
Q

What is an ad valoram tax

A

It is a tax as a % of a price (e.g. VAT)

94
Q

what is VAT as atm

A

20%

95
Q

How will the supply curve shift on a ad valoram tax diagram

A

it will shifted pivated to the origin of the original supply curve

96
Q

what are the key impacts of an indirect tax on the market

(graph)

A
  • An indirect tac will increase cost of production for firms so the supply curve will shift upwards
  • It will increase price and will decrease quantity
97
Q

what is consumer and producer burden/incidence

A
  • How much of a tax the consumer and producer pay
  • consumer budren is difference in pretax price and post tax price
  • producer burden is what ever is left
98
Q

Draw a full specific indirect tax, label what every part of the grpah means

A

Goverment revenue: P2, B, C, E
consumer burden:P2, B, D, P1
producer burden:P1, D, C ,E
Producer revenue: E, C Q1, origin
Dead-weight welfare loss: A, B, C

99
Q

What is the calculation for revenue

A

Price x quantity

100
Q

What is the effect of an indirect tax on producer revenue

A

it will decrease producer revenue

101
Q

what is the definition of deadweight welfare loss

A
  • cost to society created by market inefficiency
  • ^occurs when supply and demand are out of equilibrium.
  • the loss is not recovered by anyone
102
Q

what will be the attidue of consumers towards indirect taxes and why is this such

A
  • consumers will not like it as it will as it will increase price and decrease consumer surplus, it will also lower quantity and choice
  • consumers are burdened by indirect tax, indirect taxes are reggressive
103
Q

What does it mean if a tax is regressive

A

They take a larger proportion of income from low income houses than they do high income houses

104
Q

What is the producers/workers attitude towards indirect taxes and why would it be such

A

They will not like indirect taxes, producers will see lower producer revenue, their producer surplus comes down, they are burdened by indirect tax, workers could potentially lose their jobs (as labour is a derived demand), because quantity is falling there is less need for workers to produce

105
Q

what is a derived demand

A

demand that comes from (is derived) from the demand for something else.

106
Q

What is the attitude of the goverment on indirect taxes and why would it be as such

give for and against

A
  • like:
    because raise revenue and solve demerit good and negative externality market failure
  • dislike:
    have lots of unintended cosequences such as the harm on consumers and the reggressive nature of the indirect tax, the harm to producers (they might shut down or leave the country), black markets might also be created, a deadweight loss is created.
107
Q

If demand is perfectly price elastic on an indirect tax what will the impacts be

A
  • The consumer burden will be nothing
  • Producers will take the entire burden
  • Goverment revenue will be lowest in this situation
108
Q

If demand is price inelastic on an indirect tax what will the key impacts be

A
  • consumer burden will be higher
  • producer burden will be lower (producers feel they can raise their prices, transfer indirect tax without a massive loss in demand)
  • Goverment revenue would be higher in this situation
109
Q

If demand is perfectly price inelastic on an indirect tax what will the impacts be

A
  • consumers will take the entire consumer burden
  • producers will take none of the burden
  • Goverment revenue will be the highest in this situation

Q

How do consumers feel about subsidys

A

they do like subsidys to an extent, because prices fall, consumer surplus goes up, theres higher quantity, higher choice, if your a low income house hold there is greater affordability, consumer savings also take place
the issue for consumers is how the subsidy is going to be funded, it is going to be tax raises, is there going to be cuts from other areas of goverment spending, is the goverment going to borrow money ( in this case debt intrest needs to be payed), there is also a oppurtinity cost assocated with the subsidy (could be spent better somewhere else)
