1.3 Introducing the market Flashcards
Theme 1
Define;
1) Effective demand
2) Individual demand
3) Market demand
1) The quantity that consumers are willing to buy at the current market price.
2) The demand of an individual or firm
3) The sum of ask individual demands in the market
A Market
Is any medium in which buyers and sellers interact and agree to trade at a price.
Draw a demand curve and show what would happen to quantity given an increase in demand
As shown, an increase in demand leads to an increase in quantity, whilst maintaining price level ‘P1’
How do prices affect the demand/supply curve?
price cause movements along the demand and supply curves.
Prices do not cause shifts in demand and supply curves.
What does each letter in the PIRATES mnemonic stand for?
Population
Income
Related goods
Advertising
Tastes and fashion
Expectations
Seasons
What are the 3 different types of supply?
1) Joint supply
2) Composite supply
3) Competitive Supply
Recall 3 reasons why the supply curve is upward sloping
1) If price increases, it’s more profitable for firms to supply the good
2) High prices encourage new firms to enter the market
3) Larger output increases costs, which are passed onto consumers in the form of higher prices
What does each letter in the PINTSWC mnemonic stand for?
Productivity
Indirect Taxes
Number of firms
Technology
Subsidies
Weather
Costs of production
How will the exchange rates affect the level of supply?
A decrease in the exchange rate boosts the costs of imports (raw materials), which increases the cost of production for firms, thus shifting the supply curve to the left.
Define and draw the market equilibrium price
This is the price where supply meets demand, and has no tendency to change (P1Q1)
What is the equilibrium in the market
Equilibrium in the market place means that the quantity suppliers wish to sell is exactly equal to the quantity customers wish to buy. Market clearing occurs at this price.
When there is excess demand imminent impact
When there is excess supply imminent impact
1) Is a shortage of that particular good or service. The market is failing to clear because the current price (P1) is below the equilibrium level.
2) is a surplus of that particular good or service. Suppliers are unable to sell some of the goods and services are available to buy. The price is too high for some potential customers.
Excess demand
Excess supply
1) Occurs when the quantity overtakes the quantity supplied = some people who want to buy at the current price will be unable to do so.
2) Occurs when the quantity supplied is greater than the quantity demanded.
Draw and describe a market in excess demand
-P2 is below market equilibrium
- Demand > Supply
-Price increases, firms supply more, consumers demand less and market returns to equilibrium (P1)
What are the cons of using the supply and demand model to explain real-world problems?
> They only show certain markets
Assume price increases means firms will supply more
Assume perfect information
Assume perfectly competitive markets
