Intro to economics Flashcards
What is a market?
Anywhere where consumers and producers meet
What is the invisible hand?
Market forces of supply and demand
Which way does the demand curve slope?
Downwards
Why does the demand curve slope downwards?
- Substitution effect : As the price of the product decreases, it becomes more attractive compared to other similar products, meaning consumers are more likely to switch and increasing the quantity demanded
- Income effect : When the price of a product falls, purchasing power increases, allowing consumers top purchase more of the good or service, leading to an increases in QD
- Law of diminishing marginal utility : As consumption increases, the marginal utility from each additional unit decreases
What is a normative and positive statement?
Normative - Subjective statements that contain a value judgement e.g “Fossil fuels should be taxed higher than renewables”
Positive - Objective statements that can be tested using facts and evidence e.g “A reduction in income would increase the people shopping in pound shops”
What is the basic economic problem?
How can the available scarce resources be used to satisfy peoples unlimited needs and wants as effectively as possible
What does a PPF show?
Shows the maximum amount of 2 goods or services an economy can produce?
Draw a PPF, what does a point on the curve, inside the curve, and outside the curve show?
On the point shows a productively efficient point as all resources are being used as efficiently as possible to produce the max possible output
Inside the curve shows a productively inefficient point, meaning some FOP’s may be sat idle e.g capital. With the current level of resources, you could build more of either good without making fewer of the other
Outside the curve shows a point that isn’t achievable with the current level of resources in the economy, more resources or better use of resources (e.g improvements in labour or technology) would be needed
What is opportunity cost?
The opportunity cost of a decision is the next best alternative that you give up in making a decision e.g if you build more houses, you give up the opportunity to build more vehicles
What is a trade off?
When you have to choose between conflicting objectives because you can’t achieve all of your objectives at the same time
What is market failure?
When markets result in undesirable outcomes
Mixed economies, free markets and command economy
Mixed economy = Public sector and private sector, government intervenes in the free market
Free markets = Economies with no government intervention and purely private sector, invisible hand
Command economy = Economies with purely public sectors
What is a rational individual assumed to have?
Total self control to maximise their utility
Economic objectives of different economic agents?
Producers - Maximise profit
Consumers - Maximise their utility (satisfaction)
Governments - Maximise the public interest
