Micro 2 Flashcards
How a Free market economy allocates resources
- allocate resources through price mechanism
- demand creates a market and firms are incentivised to use the resources to maximise their profit
- changes in equilibrium price - signals to the market to produce more or less
- consumption by individuals depends on their income and their income depends on the market value of their human capital
Efficiency in a market means
- producing goods at lowest possible cost
- minimising the quantity of resources that are needed to produce goods
- only producing goods that are needed by households
Market failure (inefficiency )
If a market fails there is a case for government intervention
- negative externalities - costs such as pollution
- lack of competition - increased prices and lower choices
- missing markets - education, healthcare and defence are under provided by the private sector
- abuse of market power (monopoly)
- Public goods
- Information failure
Advantages of a market economy
- efficiency - price mechanism allocates according to demand - competition between firms forces efficient use of inputs
- innovation and choice for consumers - better products + lower prices
- individuals are free to benefit (profit) from their own ideas, skills and efforts
Disadvantages of a market economy
- unequal access to goos and services - those without the necessary income are excluded from consumption
- individuals may not make good choices - demerit goods - the private sector will provide drugs, alcohol, high fat and sugar foods if consumers will buy them
- profit motive - may lead to firms to pay low wages, reduce quality to cut costs or even sell un-safe products
How resources are allocates in a planned economy
- the state allocates resources, deciding what and how much is produced according to its own view of peoples needs
- market prices play little or no part in informing resource allocation decisions and queuing for scarce resources was how they were rationed
Advantages of a planned economy
- money not diverted to share holders, so available to improve products and pay better wages
- resources may not be diverted to producing demerit goods
- equality - less wage inequality + more equal access type products
- prices controlled so that those most in need can access
- fewer resources wasted on duplicating goods
Disadvantages in a planned economy
- relies on government agents to decide what to produce - lacks the information the price mechanism gives about what consumers actually want
- has no information about market prices. Kit has been said soviet goods were priced using prices from the US
- limits innovation. Becomes old fashioned and uncompetitive on world markets so exports limited
Specialisation examples
- business - type of product - H&M clothes
- country - Bangladesh (textiles) - Saudi Arabia (oil)
- region - West Midlands UK (car assembly) - coast or Croatia (tourism)
- worker - doctor (oncology) - economics teacher
Gains from specialisation
- higher output - total production increase and quality improved
- variety - consumers have access to a greater range and higher quality products
- economies of scale - global trade increases the size of the market - possible to exploit EOS through lower costs
Stages of the price mechanism
- Allocate resources efficiently at equilibrium
- Ration resources by consumption
- signal excess demand and need for resources
Or - signal excess supply and need for resources
- incentivise firms to increase output to increase profit
- bidding up or down of prices
Advantages of division of labour
- raises output per person as people become proficient through constant repition of their task
- lowers the cost per unit output leading to lower prices
Disadvantages of division of labour
- work becomes repetitive and unrewarding - reduced motivation and productivity
- workers take less pride in their work and quality suffers - may lead to absence
- job dissatisfaction causes high worker turnaround
- workers who are not trained in anything will miss out on world - structural unemployment
- rise to standardised goods - lack of variety
Price mechanism functions
- signalling function - prices adjust to demonstrate where resources are valued by consumers
- incentive function -higher prices in a market causes new entrants to that market
- rationing function -the goods and services are allocated based on who needs them most (willing to pay for them)
Usefulness of PED
- care about their consumers responsiveness to price changes
- different PED values will result in different impacts on total revenue when price goes up or down
- knowing customers PED allows for price discrimination
Evaluation of PED
- an estimate - not perfect information
- PED changes in value at different points in time
- tastes and preferences causes PED to change
- tach advancements might remove switching costs (costs that a consumer incurs as a result of changing brands, suppliers, or products) or habitual behaviour (routine)
- internet enables consumers to compare prices
Usefulness of YED
- Help with marketing strategies
- incomes tend to rise over time so in the long run firms that produce + YED will so best
- income elastic - greater the potential for expansion in the market
- in a recession firms producing -YED will benefit and highly income elasticity are very vulnerable
- firms protect themselves with having both inferior and normal goods
Types of information in a market
- symmetric - when buyers and seller both have perfect knowledge - this is a standard assumption as having perfect knowledge therefore agents have rational decision
- asymmetric - when one party has better information that the other - failure to allocate resources efficiently
Types of information failure
Sellers have > than buyers
- buyers become suspicious of all second hand cars and prices have to fall to make sales
- good cars will sell for less than they are worth and bad cars may sell for more than they are worth
Buyers have > than sellers
- sellers can’t trust buyers, they human raise prices to cover the cost of bad transactions
- honest buyers paying more for their goods + services than they need to + failing to maximise utility
Moral hazard definition and example
- an economic agent does not suffer the full economic consequences of a risk
- an economic agent. Has an incentive to increase the exposure to risk because they do not bear the full costs of the risk
- driver with car insurance may be less careful
Examples of merit and demerit goods
- education
- healthcare
- renewable energy
- drugs
- alcohol
- gambling
Private goods provision reasons
Provided in order to generate profits
- able to exclude consumers from producing through use of price mechanism ( can’t afford then can’t consume)
- consumers must also compete for these goods because they are limited in supply
Public goods characteristics
Beneficial to society but which will not by provided by private firms
- non-excludability - the inability of private firms to exclude certain stompers from using products - price mechanism,m vacant exclude consumers
- non-rivalry - the inability from products to be used up - no competitive rivalry in consumption to drive up prices to generate profit
Examples of public goods
- floode defences
- police and judiciary
- military defense
- lighthouses
- beaches
- street lighting
Free rider problem
- situation where customers realise that they can still access the goods even without paying for them
- If they are paying them stop and continue to enjoy the benefits e.g. fre riding the backs of other paying customers
- over time any customer paying stops
- at some point, firms will cease to provides these goods and they will become under-provided in society
Government options (public goods)
- Do nothing therefore no provision is offered
- Provide the good or service themselves e.g. parks
- Contract out the provision of the good: accept bids from private companies who wish to provide the good or service the government excepts lowest bid price and pay the company to provide the good for them
Indirect tax reasons for provision
- increases producers costs so reduces supply and likely to lead to a rise in price for the consumer
- used when product has negative externalities
- used to internalise the externality get consumer or firm to pay full cost
- tax revenue from the tax can be used to further alleviate the externality
Advantages of tax
- corrects the market - cost to firm is closer to the cost to society
- internalises external cost whilst maintaining consumer choice - smokers can still choose to smoke but the must pay a price closer to cost to society
- works trough the price mechanism therefore simple to operate
- the amount of harm reduces because the higher price reduces the quantity consumed
- raises tax revenue to address external cost
Disadvantages of tax
- difficult to calculate the true cost of pollution/smoking and therefore set the tax accurately
- taxes raise the cost of production so when applied in one country will make firms less competitive compared to other firms abroad
- may influence firms to reallocate abroad where tax is lower
- rise in price may encourage illegal trade, smuggling and black market
- fir,s are left with less money to invest in more efficient and environmentally friendly capital
Subsidy reasons for provision
- grant provided by the government to firms to encourage the production and consumption of a good or service
- reduces production costs so may lead to a price cut
- provided on positive externalities
Advantages of a subsidy
- principle - tax payer benefits so tax payer contributes
- works through price mechanism, so it is simple to understand
- amount do benefit increases because lowering price increase consumption
- reduce costs of production is when applied in one country will make firms more competitive against firms abroad
- may attract producers from abroad giving consumers greater choice
Disadvantages of a subsidy
- costs money - opportunity cost : funds Mary be needed more elsewhere
- firms may not pass on the subsidy so prices at not fall and is consumption may stay the same
- difficult to calculate the true value of the benefit - set subsidy accurately so that the subsidy benefit > subsidy cost
- demand may be price inelastic so he effect on demand my be limited
- the firms may become dependent on government assistance and become inefficient in the long run
- may not be permanent so may be inefficient government spending as prices may eventually rise back up
Examples of prohibition (legislation or regulation)
- India alcohol is prohibited in 4 main states and price controlled in the other states
- lead to thriving black market
- third of the drinkers consume cheap and dodgy locally brewed or country liquor which has caused deaths
- consumption has grown by 38% in last 20 years
- non-communicable diseases, such as cirrhosis of liver and cardiovascular diseases. “They are increasingly relevant for public health in India and increasing alcohol use will only pronounce this trend”.
Minimum price example
- Scotland min price on alcohol of 50 pence per unit
- reduce hospital admissions + save lives
Problems with price floor
- lead to hidden markets
- unfair - some consumers will be priced out of market whereas has no effect on the wealthy
- demand contracts and supply extends therefore there is excess supply
- demand could be price inelastic then there will be no reduction in quantity and a major increase in producer profits
Black market issue
- bad quality and consumption is worse for individual than if they bought it legally
- policing costs
- loose tax revenue of there is black markets
Maximum price advantages
- fairness - the product becomes more affordable
- unlike subsidy does not cost money therefore no opportunity cost
Disadvantages of price maximum
- cause contraction of supply and excess demand leading yo product shortages
- reduces profit from business - below fixed costs - shut down
- it incentives the producers to reduce the quality of their products
- depending on price elasticity of demand, the policy may have no impact at all unless the max price is substantially below equilibrium
- incentivises consumers and producers to engage in hidden markets where cost of production is lower
Price maximum example
Rent control New York
- less houses available leading to less available workers
- increased black market - rent in cash so decreased consumer protection and no tax revenue
Government provision Reasons
- provides goods + services funded through taxation
- typically provided on goods and services which have significant positive externalities or are public goods
- prices are high otherwise and exclude consumers from merit goods e.g. healthcare and education
Advantages of government provision
- the principle - all taxpayers contribute according to their ability
- provides fairer access to to services e.g. education and healthcare for free or low cost
- without provision public goods would bot e provided at all so state provision resolves the free rider problem
- services not driven by profit motive so may be more adorable or of a higher quantity
Disadvantages of government provision
- costs money - opportunity cost
- state provision can be less efficient, more bureaucratic + expensive to run because there is no competition between firms to keep costs and prices down therefore no profit incentive
- no price mechainsm to determine hoe much should be provided
- government might have lack of expertise in the provision of the good required
- abuse free provision e.g. overusing healthcare
Buffer stock system analysis
- stabilises prices in volatile market
- ensure the supply of good
- prevent farmers/producers going out of business because of a drop in prices
- a commodity is a tangible good that can be sold or exchanged for products of a similar value
- prices are volatile because supply can vary greatly, demand is inelastic and supply is fixed in the SR
Advantages of buffer stock
- stable prices help maintain farmer income - a rapid drop on prices can make farmers hop out of business - structural unemployment
- price stability encourages more investment
- farming can have positive externalities e.g. help rural economies - drop in prices our have negative multiplier on areas
- targets prices help prevent excess prices for consumers and reduce food inflation - important for households in poverty who might struggle to pay high prices during years of shortage
- possible for government to make profit from a buffer stock system - but during glut and sells during a shortage
Problems with buffer stock
- cost of buying excess supply and become quite high for the government and may require higher taxes to fund
- minimum prices and buffer stocks could encourage excess use for chemicals to maximise yields because farmers know excess will be sold even if market doesn’t want it
- some goods can’t be stored e.g. milk and meat
- government agencies my macro pure information therefore difficult to know wether there will be a surplus
- administration costs of the schemes may be high
- globalised markets (agriculture) if some countries form a buffer stock scheme and buy excess supply and they may find that other countries will free rife on their efforts to keep prices high and undercut them
Buffer stock examples
- India releasing 50,000 tonnes of onion to stabilise prices to states with shortages
- Australian wool - incorrect price settings and constant excess supply huge cost for government - incurring 1 billion a year in storage costs and interest
Information provision reasons
Market failure of asymmetric information
- provides information to allow consumers to make informed decisions
- force companies to provide information when it is negative and positive
- e.g drug adverts in America are required to state all major side effects
Advantages of information provision
- protect consumers from unknown harm
- slow consumers to act rationally which helps market to function properly
- e.g. cigarettes packaging - smoking kills and healthy vs smoker lungs
Disadvantages of information provision
- consumers can still choose to ignore information 1/8 of uk still smokes
- expensive - opportunity cost
- government might not have the necessary information or information consumers need to have
- forcing producers increases costs + may push business out of business
Pollution permits analysis
- cap and trade
- governments decide total amount of emissions of CO2 that will be allowed + polluting industries are granted a percentage of total in form of a permit
- firms can trade permits with each other e.g. market based solution
- energy efficient firms earn money from selling unwanted permits therefore incentivising firms to shift to greener production
- heavy pollutants have to pay to buy more permits
Examples of pollution permits
- Kyoto protocol -not signed Australia + US and China
- Czech airlines makes more revenue from selling permits than from flying
Advantages of pollution permits
- Gov can reduce emissions further by reducing no. of permits in the long run
- more efficient then taxes + fines
- minimises social cost - polluter will spend min and pollution decreases
- helps old industries that cannot easily reduce pollution
