Q

market adjustment (price < equilibrium price)

A

Q

marginalist principle for dd

A

experiences diminishing marginal utility in consuming additional units of a good –> max. utility with given budget –> rational consumer increase qty dd as price decreases –> downward sloping dd curve

Q

marginalist principle for ss

A

ldmr states that beyond a certain point of production, adding an additional fop results in smaller increases in output to max profits, the rational producer will increase outputs as prices increases and vice versa

23
Q

producer surplus

A

difference between what producers are willing and able to receive and what they actually receive

24
Q

price elasticity of demand

A

measure of degree of responsiveness of the qty dd of a good to change in its price, ceteris paribus

25
Q

sign of ped

A

negative to reflect law of demand

26
Q

magnitude

A

more than one –> price elastic, more than proportionate rise/fall in qd
less than one but more than zero, price inelastic, less than proportionate rise/fall in qd

27
Q

applications of ped

A
  1. effect of price change on qty dd
  2. effect of total revenue of firm (draw diagram)
  3. decisions the firms can make to raise total revenue
28
Q

determinants of ped

A

shit –> substitutes, habituality of consumption, (proportion of) income spent, time horizon

29
Q

pes

A

measure of degree of responsiveness of the qty supplied of a good to change in its price, ceteris paribus

30
Q

sign

A

pawsitive (law of supply)

31
Q

magnitude

A

0<pes<1, inelastic
pes>1, elastic

32
Q

applications pes

A

price change, qty change differently due to pes

total revenue

33
Q

determinants pes

A

level of stock, avail of spare capacity, mobility of fop (btwn industries), time horizon (momentary perfectly price inelastic, short run restricted by at least one fop relatively price inelastic, long run all fop variable), length of production

34
Q

ced

A

measure of degree of responsiveness of the qty dd of a good to a change in the price of another good, ceteris paribus

35
Q

sign

A

ced>0, substitutes
ced<0, complements
ced=0, unrelated

36
Q

magnitude of pes

A

closer relationship = larger magnitude

37
Q

applications pes

A

fall in price of substitute: price comp and decrease price, make good less substitutable like advertising

fall in price of complement: output planning increase prod, collab

38
Q

yed

A

degree of responsiveness of the qty demanded of a good to a change in income, ceteris paribus

39
Q

sign yed

A

positive for normal goods (necessities –> inelastic demand and not very sensitive, luxuries –> elastic and very sensitive), negative for inferior goods

40
Q

magnitude yed

A

the more responsive the qd is to changes in income, the larger the magnitude

41
Q

determinants of yed

A

degree of necessity –> necessity vs luxury (depends on level of income of consumers, and stage of development of their economy)

42
Q

applications of yed

A

firms will: (economic growth)
channel resources to sales of luxury goods, market luxury goods

recession
channel resources from sales of luxury goods to normal goods, promote inferior goods

segment consumer base

43
Q

limitations of elasticity principles

A

ceteris paribus assumption: changes in qd can be attributed to various factors and diff to keep all other factors constant

cost concerns:
if increasing tr will also increase costs, profit will not rise

prediction issues:
calculations done from past data may not be accurate in the future

computation issues:
involves collecting price and qty data, inaccurate data = inaccurate analysis

44
Q

direct subsidy

A

granted directly to buyers
increases buyers’ disposable income

45
Q

indirect subsidy

A

granted indirectly through sellers, lowers sellers’ cop

46
Q

direct tax

A

granted directly to buyers
decreases buyers’ disposable income and purchasing power

47
Q

indirect tax

A

raises cop, paid indirectly by consumers thru sellers (ad valorem tax has pivotal shift)

48
Q

price ceiling good and bad

A

good:
ensure affordability

bad:
inefficiencies
chronic shortage
black market
deadweight loss

49
Q

price ceiling

A

maximum price
set below market equilibrium price
legally established

50
Q

price floor good and bad

A

good:
protect income
minimum wage

bad:
involves g spending of buying surplus
surplus loss
deadweight loss

51
Q

price floor

A

minimum price
legally established
set above market price

52
Q

quota

A

limit on quantity produced, less than equilibrium qty
legally established
affects ss, at quota ss is fixed (perfectly price inelastic) (theres also deadweight loss)

53
Q

labour market

A

buyers of labour= firms, sellers of labour= households

54
Q

labour demand

A

depends on how much revenue each unit of labour can bring to the firm
1. dd for final good (derived dd)
2. productivity of labour
3. supply of alt and complementary fop

55
Q

labour supply

A
  1. immigration
  2. educational attainment
  3. non-wage benefits of job
  4. alt employment opportunities
56
Q

minimum wage good and bad

A

good:
increases income and standard of living and inclusive growth

bad:
1. higher unemployment
2. illegal employment below minimum wage
3. encourages substitution with other fop

57
Q

wage differentials

A
  1. imperfect market (trade union/ monopsony)
  2. discrimination
  3. ped/pes
  4. minimum wage
