unit 1 notes Flashcards
Basic economic problem
The economic problem is that there is too much demand for too few goods as a result of human greed and competing wants. Not all wants can be satisfied.
Human wants are unlimited and resources (land,labour,capital,enterprise) are finite (scarce)
The problem is universal and permanent; affecting both developed and developing countries.
Because of the basic economic problem, choices have to be made
Opportunity cost is the cost of giving up the next best alternative.
The purpose of economics is to help advise the best use of resources in order to make goods and services that will satisfy as many people as possible
Scarcity vs shortages
Scarcity: OC arises as there are insufficient resources to supply consumers (or firms or governments) with everything they want, forcing them to make choices. This is called an OC
(scarcity is the basic economic problem)
Shortages: insufficient resources to supply consumers with what they demand at a particular time. (i.e.) what they are willing and able to pay. A shortage can be controlled through price movements.
How to reduce scarcity
Finding new resources, for example new oil reserves
Specialisation, in order to improve efficient use of scarce resources
Alternative resources, for example switching from fossil fuels to wind energy
Encouraging immigration, to increase supply of labour
Resources
Land - all the natural resources of earth.
Examples: fish in the sea, oil, rocks, metals e.t.c.
The reward for land is ‘rent’
labour - all the human mental and physical effort that goes into production.
Examples: cleaners, teachers, bricklayers
The reward for labour is ‘wages’
Capital - all the equipment, machinery and buildings that is not used for its own sake but for the contribution it makes to production
Examples; desks, chairs, lorries, machinery
The ‘price’ for capital is ‘interest’
Enterprise - the skills needed to organise other resources into some form of production.
The return for enterprise is ‘profit’
Economic Goods
Goods with an opportunity cost
Scarce resources are used up in the production of economic goods
Example: A television
Free Goods
Goods in plentiful supply, enough to satisfy the want of everyone
They have no opportunity cost
Example: Air
Choices
Governments make choices to maximise social welfare
Businesses make choices to maximise profits
Individuals make choices to maximise satisfaction
Effective demand
is when consumers have enough money to buy goods and services at various prices
Individual demand
Is the demand of just one consumer
market/aggregate demand
the total demand for a product from all its consumers
Derived demand
when a product is demanded due to it being part of the production process of other products e.g. demand for garden sheds generates demand for timber.
Non price factors - shifts in demand curve
tastes/preferences: a change in tastes in favour of the product will lead to more demand and will cause the demand curve to shift to the right etc
Disposable income: an increase in disposable income will provide people with more financial freedom to purchase more units of a good
Substitute goods: a change in the price on one product will lead to change in demand for substitute products. For example if there’s a fall in the price of chicken, people will switch to chicken from beef and so chicken will be in higher demand.
Complementary goods: products that are often bought together, e.g. jam and scones. If a price fall for jam goes down then there will also increase demand in scones.
Unrelated goods: if products are unrelated, then a change in the price of one product will have no effect upon the demand for the other product.
3 reasons why the demand curve slopes downwards(need definitions)
The Diminishing Marginal Utility Effect – as consumers increase consumption of a good or service they experience the law of diminishing marginal utility. As their satisfaction falls after each marginal unit they are prepared to pay less to consume more.
The Substitution Effect – as the price rises then the marginal utility per £ of the last unit consumed falls. A rational consumer would therefore switch consumption to a substitute product that offered greater utility at a cheaper price i.e. one which they view as better value for money.
The Income Effect – as the price rises then a person’s real income (i.e. their buying power) falls so they are no longer able to buy the same quantity. Demand for the product then falls.
Explain 3 reasons why the demand curve for some goods slopes upwards from left to right
Giffen/essential goods (ID) as low income consumers may cancel consumption of other goods and use their income to buy more of these essential goods (EXP) (1)
Veblen/ostentatious goods (ID) as some consumers will demand more as they wish to demonstrate their wealth (EXP) (1)
speculative demand (ID) results in consumers buying more of a good as they think it will be worth more in the future (EXP) (1)
Movements in demand curve (contraction/extension)
A change in price leads to a change in quantity demanded (a movement along the demand curve).
When prices INCREASE – there is a CONTRACTION of the demand curve i.e. less is demanded
When prices DECREASE – there is an EXTENSION of the demand curve i.e. more is demanded
A change in price will lead to a movement along the supply curve, ceteris paribus because of the profit motive.
