the role of markets and money Flashcards
market
a way of bringing together buyers and sellers to buy and sell goods and services
market economy
an economy in which scarce resources are allocated by the market forces of supply and demand
primary sector
the direct use of natural resources such as the extraction of basic materials and goods from land and sea e.g farming and mining
secondary sector
all activities in an economy concerned with either manufacturing or construction
tertiary sector
all activities in an economy that involve the idea of service eg. teaching, entertainment, health
product market
where final goods and services are offered to consumers, businesses and the public sector
what is the price determined by - product market
determined by the intersection of supply and demand for a good/ service
factor market
where the services of the factors of production are bought and sold, e.g. skills of a workforce, suitability of land
what is the price in a factor market affected by?
interaction of demand (depends on the demand for a good/service) and supply (labour from households in return for wages)
interdependence of factor and product markers
households own the factors of production in the factor market and sell to firms. in the product market, households are the main buyers while firms sell the goods and services.
specialisation
the process by which individuals, firms, regions and countries concentrate on producing those products they are best at doing - they may have to give up the making of other goods
exchange
the giving up of something that an individual or firm has in return for something they wish to have, but do not possess - usually money is used
what groups are affected by specialisation and exchange
producers, workers, regions and countries
costs of specialisation for producers
- diseconomies of scale : as output increases, costs may rise, maybe resources in shorter supply or more people to manage workforce
- dependency - if one part of the process fails the whole production could stop
- maybe not able to buy necessary scarce resources, maybe if prices of those resources are raised by the producer
- if workers become bored and leave or produce less
benefits of specialisation for producers
- higher output of goods
- higher productivity as workers become more skilled in one specific area
- higher quality because the best factors can be employed + you can buy the best components from specialists rather than making them
- bigger market for each product means there should be more buyers for each product we
- economies of scale bc of larger output
- time saving because only one product is made, no stopping to start and finish another product
what is specialisation by individuals called
division of labour
benefits of specialisation for workers
- increased skill level leading to more money being earned (through bonuses, promotions etc)
- workers doing what they’re best at leads to them becoming more skilled
- doing what they’re good good at uncreated job satisfaction meaning more motivation and more money
- increased standard of living by earning more
costs or specialisation for workers
- boredom leading to demotivation
- deskilling because they lose skills to other types of work and can’t respond to changes in demand
- unemployment if there’s a fall in demand for the product they specialise in and also replaced by machines
specialisation in regions
regions within a country can specialise in specific areas like coal in the north
benefits of specialisation for regions
- a region uses its own resources efficiently
- creates jobs for residents
- development of better infrastructure and therefore supply industries that will develop the region
costs of specialisation for regions
- if demand falls then the industry may collapse
- if resources run out then those in the induration will become unemployed
- loss of advantage if another region becomes better at producing the specialised product leading to unemployment
benefits of specialisation for countries
- greater efficiency and output when doing what they do best
- more output leads to more investment and jobs
- international trade means more products for its own people
- increased choice, income, output and infrastructure meaning better standard of living
- government revenue increased leading to better school, hospitals etc
costs of specialisation for countries
- as specialisation for a country changes, workers in that industry become unemployed
- if world demand changes then the economy may collapse if the country over specialises
- over exploration of resources so unsustainable development or environmental damage
demand
the quantity of goods and services that consumers are willing and able to buy at a given price in a given period of time, usually varies inversely with price
individual demand
the demand for a good or service by an individual consumer, shows how much a consumer is prepared to buy at different prices not what theyactually will buy
market demand
the total demand for a good or service round by adding together all individual demand
shifts of the demand curve
a compete movement of the existing demand curve either outward or inward
movement along the demand curve
when the price changed (due to change in supply, leading to a contraction (up) or expansion (down) the demand curve
what causes shifts of the demand curve
- increase in income - consumers can buy more products at every price
- increased in marketing - persuades consumers to demand more products at every price
- changes in taste and fashion - if something becomes trendy the demand will increase
- preference for a substitute - some people might like pepsi more than coke so demand for pepsi will increase
- complementary goods - if the price for one good falls then the demand for any good that goes with it will increase like cars and petrol
- expectations of prices to rise - consumers will buy more products now to save money in the future like sales
- population changes - more population means more demands, gender patterns and ageing population means different goods are more popular
- government prices - a subsidy or cut in tan will increase consumer demand
subsidy
an amount of money a government gives directly to forms to encourage production and consumption
Consequences of shifts of demand
In nearly all situations a shift leads to price and quantity moving in the same direction
exceptions to quantity and price both rising/falling (shift of demand curve)
- If income rises faster than prices then consumers can demand more
- if a substitute is preferred then demand will fall even if price increases
- if the increase in demand allows firms to gain economies of scale, they could cut prices leading to an increase in demand
- if demand falls a form could go out of business
What causes movements along the demand curve
caused only by a change in price/supply
Consequences of movements along the demand curve
Price and quantity move in opposite directions
What is the effect of contraction of demand
Price rises, quantity falls
Effect on consumers : buy fewer goods, buy cheaper substitutes
Effect on firms : sales and profits fall, may need fewer workers
What is the effect of expansion of demand
Fall in price, rise in quantity
Effect on consumers : buy more and better goods
Effect on firms : increase supply and profit, employ more workers
Firm
A single supplier of a specific good or service
Industry
All of the firms which supply a specific good or service
Utility
The satisfaction received from the consumption of a good or service
Necessity
Essential for survival
Luxury
A ‘nice to have’ but not essential good/service
PED
The responsiveness of quantity demanded to a change in the price of a product
Elastic demand
When the % change in quantity demanded is greater than the % change in price
Values of PED
PED 0 - perfectly inelastic
PED ∞ - perfectly price inelastic
PED -1 - unitary price elastic
PED more than -1 (eg. -2, -3.5, -6) - price elastic
PED less than -1 (e.g. 0 or 0.25) - price inelastic
What do PED and PES values have to have
always include the - sign in the PED value to shows the demand curve sloping downward, PES is always + due to the positive slope
5 PED curves
Price elastic, price inelastic, perfectly price inelastic, perfectly price elastic, unitary price elastic
What is the importance of PED for consumers
- if the product they buy has inelastic demand they can face price rises as suppliers can pass on cost increases
- the government can impose high taxes easing prices if the product has inelastic demand
- allows them to make choices if substitutes available
- consumers PED depends on factors like weather/ time if day (eg train times)
Importance of PED for producers
- allows producers to maximise their total revenue
- can charge different prices to different groups for the same product
- can affect their decision whether to supply the product or not
Revenue equation
Total revenue = price x quantity
The effect of a price change on total revenue : demand is price elastic
Decrease in price : revenue increases because 🔺q > 🔺p
Increase in price : revenue decrease because 🔺q> 🔺p
The effect of a price change on total revenue : demand is price inelastic
Price decreases : tr decreases because 🔺q<🔺p
Price increases : tr increases because 🔺q<change in price
Calculating PED values
PED = - %🔺q / %🔺p
Supply
the quantity of goods and services that producers are willing and able to supply at a given price in a given period of time, usually varies directly with price
What causes a movement along a supply curve
It is caused only by a change in price/ demand
Causes of shifts of the supply curve
- increases in costs of production - producers would supply less at each price
- increase in taxes and subsides
- new technology - fall in costs so rightward shift
- climate change - in agriculture can cause less to be supplied
- increases in producers/ size of firms - more supplier at every price so rightward shift
- government regulation - increase in costs so shift to the left
Shift of the supply curve
A complete movement of the existing supply curve either outward or inward showing either more or less supplied at every price
Consequences of shifts in supply
- Gain greater economies or scale - greater profits for the producer and lower prices for consumers
- increases in efficiency - increase in profit and possibly greater productivity
- increases in exports - greater economies of scale, increases in efficiency and fall in price makes firm more competitive
- increase in sales - in price falls consumers will buy more leading to increase in profit
- becoming a monopoly/oligopoly - a more competitive firm gains market share and forces competitors out
Consequences or price rising (movements along the supply curve)
Change in quantity: rise
Effect on producers: initial increase in profits, but then more firms enter the market shifting supply to the right which might reduce profit
Effect on consumers : products are initially more expensive but then price falls - consumers have more choice and can buy more products
Consequences of fall in price (movements along the supply curve)
Quantity falls
Effect on producers : reduction in profits, less efficient firms forced our, reduction in output
Effect on consumers ; consumers can afford more but now have less choice
PES
The responsiveness of quantity supplied to a change in the price of the product
Elastic supply
Percentage change in quantity supplied is greater than the percentage change in price
How to calculate PES
+ % change in supply / % change in price
Values of PED
0- no change in quality as price changes
Between 0 and 1 - change in quantity is less than change in price
1 - change in quantity is equal to the change in price
Between 0 and ♾️ - change in quantity is more than the change in price
♾️ - an infinite amount can be supplied at the given price, no change in price
