Q

Determinants of PES?

A
-Availability of stocks 
(Price^ then stocks sold at high price)

Q

Business significance of XED?

A

If large + XED then lower price to steal market competition as close substitutes
If large -XED then prepare if complement price changes

17
Q

PES ALWAYS POSITIVE ( uses?)

A

Can prepare excess stock if expect a P^
Fops can be re allocated to respond to change in price (^ or decrease labour)
So they can aim for elastic supplies

18
Q

Calculate ped

A

%^P

19
Q

PED less than 1

A

Inelastic

20
Q

YED less than 1

A

Income Inelastic
Not very responsive to change in Y
(Change in Y > change in QD)

21
Q

PES less than 1

A

Price Inelastic

22
Q

Specialisation + benefits

A

Concentration of labour on a narrow range of g and s

  • increased output
  • ^ range of goods available in economy
23
Q

Specialisation - cons

A
  • cheap imports lead to loss of jobs
  • tastes and needs change, specific economy suffers
  • finite resources run out = no trade
24
Q

Division of labour + -

A

Specialisation of labour- production process broken down into separate taks

  • productivity^
  • many workers low paid
  • monotonous + boring =poor quality
25
Q

Free market

A

Resources allocated through market forces of D and S

26
Q

Command market

A

Most resources state owned + allocated centrally

27
Q

Mixed market -

A

combination of D and S market forces and state allocation of resources

28
Q

Determinants of Demand

A
Income 
Price of alternatives 
Tastes + fashion
Advertising 
Population size
29
Q

Determinants of supply

A
Cop
Size of industry 
Advancement in technology
Govt policy 
Other factors (hurricanes)
