Q

give me formulas for MNB and HNB

A

Monetary net benefits → MNB = (Rc * @E) - @C (i.e you monetise the net benefit)

Health net benefits → HNB = @E - (@C / Rc) (i.e you convert costs into the same units as effects e.g life years gained)

The treatment is cost-effective if the MNB or HNB > 0
@ = change in

Q

In different economic analysis, what are the different outcomes?

A

Monetary benefit → e.g money saved from reduced number of doctors needed / productivity gains

Effectiveness measures → e.g early diagnosis, life years gained etc.

Various utility measures → such as QALYs and DALYs

Q

what are the 3 main methods to calulate QOL (not SF-36, etc)

A

**Standard gamble (SG) **→ the standard gamble is similar to time trade-off but with probabilities - where you set up a scenario where participants make a comparison between living with no treatment or going for an option where there is a “p” chance of living in full health but a “1 - p” chance of death:

**Time trade off (TTO) **→ stated preferences to death and alternatives, it would make subjects find the indifference point as a ratio of the LOL healthy vs the LOL in suboptimal health (the trade off) for example in the case of a broken leg you would as how many years of life make you indifferent between living with a broken leg and living healthily e.g

Visual analogue scale (rate scaling) → you ask people to rate on a visual analogue scale that if they had a particular health condition where they would rate their quality of life (or you can also derive it from people who have experienced the disease / condition) rating from 0 (no QOL) to 1 (full health)

Q

Explain DALYs

A

Life LOST
Rated by professionals

DALYS (disability adjusted life years) are a measure from the WHO and World Bank data as a measure of population ill-health

It represents the time people live with a disability including the time they lose due to premature mortality

**It is rates on 0 (perfect health) to 1 (maximum disability)
**
They will ask experts on the condition to answer the quality of life which would occur from a certain disability (IN THE local population)

Q

Give me niche concept about indiffernce curves and how to calculate marginal rate of subsitution

A

Curves never cross
if MRS is 2 then it means decreasing x axis by 1 would need there to be an increase of y axis of 2 to give the same utility

Q

Explain the utility maximizing rule for the indifference curves

A

MUx/Px == MUy/Py (i.e where budget line meets curve)
if MUx/Px is larger then you need to get more x until MUx decreases!

Q

Explain how environmental factors affect health demand

A

Environmental factors also affect demand, e.g how much you demand will depend on the type of insurance:

Co-insurance → for example those fully insured purchase roughly 40% more healthcare than those not fully insured

Deductibles

Q

Explain Production frontier

A

You have a SET AMOUNT OF INPUT and you’re varying the amount of outputS (combination) you can get.

You should be on the line, belwo is ineffcient. Above= no budget ot increase input
However curve can move up due to tech that maximises outputS with same input

Optimal point is just when is bends

Q

Explain RPT

A

Gradient at a point on
the PPF is the rate of PPF
product transformation.

The quantity of one product that must be forgone in (OPPORTUNITY COST) order to obtain more of the other without varying the input level

20
Q

what factors affect the supply curve (not price)

A

Input prices (cost) will shift it leftwards

Technology increase will reduce marginal cost and shift it outwards

Expectations:

Number of sellers increases shifts the curve to the right

21
Q

Define market wuilibrium, adjustment and efficiency

A

Market equilibrium → is where the competitive market will find a price equating to the quantity supplied vs the quantity demanded without external guidance (naturally)

Market efficiency → implies self-interested buyers and sellers in a competitive market for a private good find the efficient (surplus maximising) allocation of a particular good

Market adjustment → is where a shift in the supply / demand such that the competitive market must find a new price equating to the supply and demand

22
Q

Outline diseconomies of scale

A

Diseconomies of scale =

larger levels of output lead to a point where MC (cost per additional unit) will increase and total costs will rapidly rise

23
Q

Explain minimum efficient scale

A

HOWEVER beyond the point where MC=AC (MES) there are diseconomies of scale

24
Q

Outline consumer and producer surplus

A

Consumer = WTP- p
Producer = P - cost

25
Q

what are the three main insights concerning market outcomes

A

Free markets allocate the supply of goods to the buyers
who value them most highly, as measured by their
willingness to pay.

  • Free markets allocate the demand for goods to the sellers
    who can produce them at least cost.
  • Free markets produce the quantity of goods that
    maximizes the sum of consumer and producer surplus (allocative efficiency)
26
Q

Equation for elasticity of demand

A

PERCENTAGE CHANGE (PRICE IS BOTTOM)

27
Q

Explain the outcomes for cross-price elasticities

A

This is** negative with complements **→ i.e subjects who cannot afford drugs may not bother even going to the doctor OR people who cannot afford DVD players will not buy DVDs

This is **positive with substitutes **→ i.e people who cannot afford one alternative will subsequently have higher demand for the other alternative (e.g outpatient vs inpatient services)

unrelated = zero

28
Q

Demand

outline types of goods in relation to elasticity and income

A
29
Q

Outline the different market structures

A
30
Q

Outline the perfect market conditions and how does healthcare remove that

A
31
Q

what are the types of monopoly

A

Natural monopoly (increasing returns to scale)
* e.g. (parts of) utilities companies?

They can adjust output- which changes the price

Artificial monopoly
* a patent (e.g. market for a new drug)
* sole ownership of a resource (e.g. a toll bridge)
* formation of a cartel (e.g. OPEC)

32
Q

Since monopolies fail to allocate resources efficently, what may be done?
what else may cause market failure?

A

Make monopolized industries more competitive
* Regulating the behavior of the monopolies
* Turning some private monopolies into public
enterprises
* Do nothing at all?

33
Q

Give real life examples of externalities

A
34
Q

Explain potential solutions to adverse selection

A

Experience rating – setting a different insurance premium for different risk groups

Compulsory – low risks can’t drop out
* * Consequences depend on burden of finance
* * May be inequitable to low risk individuals

Genetic testing and price discrimination

Government provision

35
Q

what is the end result of adverse selection in health insurance if not solved

A

Customers knows risk more than inusrers,
Lower risk pts don’t buy it cus they don’t need to
Hihger risk pts buy it… profits fall which then causes prices to rise

36
Q

Explain the two types of Moral Hazard

There’s consumer and producer MH

A

Ex Ante MH: refers to the situation prior to the
advent of illness, the individual increases the
probably of illness and/or its consequences by his
actions

Ex Post MH : comes to play once the health loss has
already occurred

Consumer

37
Q

what are solutions to consumer moral hazard

A

Patient payments
* e.g. deductibles / co-insurance

The higher the co-payment the greater the reduction in
the welfare loss
* Loss=0 for no insurance
* But might lead to too little insurance levels
* Trade off

**No claims bonuses **are used in most insurance markets

38
Q

when does provider moral hazard occur

A

when insurer finances provision rather than pts. Can lead to :
SID underpinned by Principal Agent problem

39
Q

what are the solutions to producer moral hazard

A

Change reimbursement regime

  • from retrospective (e.g. fee for service) to prospective (e.g. global budgets) reimbursement
  • Closer links between third party payer and provider
  • Increased regulation by government and/or peer groups

Effectiveness depends on doctors objective

40
Q

what behaviour can emerge out of the principal agent problem

A

Too little or much care depended on one that will **maximise profit **

Target income

Supplier induced demand

41
Q

How can you definitely tell theres SID

A

SID is only CONFIRMED if there is increased supply causing INCREASE in quantity supplied (Q) AND INCREASE in price (P)

42
Q

what incentives can exercebate SID?

A

Financial Incentives
* Fee-for-service: over provision of service
* Third-party payment: no concern of consumer loss
* Activity based payments

43
Q

EXPLAIN Merit Good

A

Goods in which people do not realsies the full benefit of it at time of consumption , leads to loss of information and hence underconsumption can market failure

treated like positive consumer externality

44
Q

what are the two types of equity

A

Vertical equity = the unequal treatment of unequal things
* K(KAWAKANI index)

Horizontal equity = the equal treatment of equal things

N.B. may try to use utility frontier but it’s subjective

45
Q

what are the 4 types of horizontal equity

A

Utalitarianism (sum ranking) → where you maximise the outcome but there is unequal distribution of resources

Maxmin → where you compensate the most vulnerable BUT again it leads to unequal distribution and lower welfare

Egalitarianism → equality in the outcomes BUT non-equal distribution in the resources

Fair innings → where everybody is entitled to a normal span of life at a reasonable level of quality but after that there is no entitlement

46
Q

what are the different nuances of equality?

A
47
Q

what are public goods?

A

Public goods are neither rival in consumption nor excludable. Examples of public goods include:

  • national defense.
  • eradication of a disease
  • creation of fundamental knowledge.

Because people are not charged for their use of the public good, they have an incentive to free ride when the good is provided privately. Therefore, governments provide public goods, making their decision about the quantity of each good based on cost-benefit analysis
