Risk taking
Decision making
Organise other FoP

deregulation / end monopolies to remove barriers to entry
income / consumer spending
Investment
Spending on capital goods, increase AD; more advanced technology, higher AS
Higher quality due to capital and R & D, higher D and higher D(X)
Investment in human capital increases productivity
Occupational mobility of labour










































































































workers are more skilled, lower structural unemployment
find another job quickly when unemployed, lower frictional unemployment
firms can quickly respond market changes, by changing roles of labour, filling
vacancies easily, greater use of resources


























SECTION 1 The basic economic problem

Planned / market economic system
Who decides what is produced (sovereign): government / consumers
How resources are allocated: government / price mechanism
Who owns the capital and land: government / private
Market economic system
Adv
Economic freedom, consumers and producers make own decisions,
consumer sovereignty
Competition encourages efficiency to keep competitiveness, higher
quality, lower cost, lower P, more affordable
Respond to consumers’ D, wider choice
No government intervention, more efficient allocation of resource by
price mechanism
Dis
May cause market failure, unemployment, instability e
...
inflation,
exploitation of workers
Uneven distribution of income causes poverty
Poor consumers have no sovereign due to little purchasing power
Capital / labour-intensive
The use of high proportion of capital / labour relative to another
Capital-intensive
higher productivity
improved quality due to fewer mistakes
lower average cost in a long term
Labour-intensive
more flexible
personal services, personalised products
low start cost
contribution to ideas
Factors shift D
Income
Related goods: substitutes & complements
Advertisement
Awareness of e
...
environment, health
Population (of the niche market consumers)
Change in taste & fashion
Expectation / confidence of future price / income
The factor derives it










































































































Factors shift S


















SECTION 2 The allocation of resources

Effect of P decreasing
consumers can buy more of that product and other products, higher l
...

if necessities, more affordable, lower poverty
if FoP, lower cost of production, attract investment and MNC
PED
A measure of the responsiveness
Of the QD to a ∆P
= %∆QD / %∆P
Factors change PED
Availability of substitutes
Consumer will switch or not
Proportion of income spent on the product e
...
small
Insignificant ∆P when %∆P is large, still buy
Necessity / luxury
Still buy when P(necessity) increases
Addictiveness / habit
If so, difficult to stop buying
How wide the market is defined
Wider, less substitutes
Time
Price along D
More elastic at higher prices, consumers more sensitive
Shift of D
To right, PED decreases
Easiness to postpone purchasing
PED in decision making
Producers decide P to maximise revenue
Producers try to remain competitive to reduce PED
Indirect tax to discourage consumption will be more successful if PED is elastic

























































































































Factors change PES
Time taken to produce
E
...
time for livestock / crop to mature
Cost of altering the supply
E
...
recruitment, if at full capacity (theatre)
Storage
Agricultural goods are difficult to store












Costs, labour productivity, advance in technology
Natural conditions / supplies
Price of competitors
Quantity of resources
Tax & subsidies

Time
Time allows flexibility
In long run, all FoP can change




























PES in decision making
Producers want PES to be elastic
Higher profit when D increases
Take greater adv when price increases
Government want to subsidise elastic producers as effect will be more significant
Government promotes flexibility in production / mobility of FoP, more efficient

keep costs low, respond to consumers’ demand, higher efficiency
Higher investment, R & D, higher quality, lower costs, wider choices
Easier to raise finance by selling shares
Not require tax revenue to fund
Public
No monopoly
Charge low price to help the poor and ensure access
Take into account external C & B, for social welfare
May be largely funded by the government for R & D and expansion for EoS
Less likely to go out of business so continuity of supplies
