Law of supply (ch7) and workbook qs Flashcards
intersection of demand curve and supply curve
equilibrium price
Individual supply is
the various quantities of good or a service that sellers will place on the market per unit of time
Market supply
total of supply of all the individual firms (total production of the society)- resources, labour depended
State the law of supply and explain it.
the higher the price, the larger the quantity produced
- because more profit can be made by suppliers
- profit= motivation of suppliers to produce more products
- stimulates mores suppliers to produce this product
- encouraging new firms to join this industry
Factors affecting supply/ determinants of supply
- price of the good or service itself
- influence the producer’s ability and willingness to supply it - - (expectation of suppliers about the future price of a good or service also influences the supply- due to the possibility of increased profit arising from the supply of the good. - price of other goods or services
- if prices of alternative goods and services are higher than others, producers may want to supply the alternative g&s if prices and profits are potentially higher in the market - state of technology
- improvements in technology lower production costs, less lead time and new products, which enable producers to increase supply - Changes in the cost of factors in production
- lower production costs will enable producers to increase supply over a range of prices
- higher production costs force producers to reduce supply
- quantity and quality of resources also impact on supply and overall production costs - The quantity of the good available
- e.g. limited number of electric cars supplied, but when more suppliers enter the market, supply increase - Climatic and seasonal influences
- changes in climatic conditions and sessions affect the agricultural production
- e.g. drought causes supply issues in agricultural products such as rice, wheat
price ceiling
A type of price control where the law mandates the highest point where a good/ service can be sold
Elasticity of supply
How responsive the quantity supplied is to a change in price
Said to be elastic when
An increase in price increases the quantity supplied a lot (or decrease)
- less steep
Said to be inelastic when
The same increase in price increases quantity supplied just a little.
- steeper
determinant of the elasticity of supply
-
1. how quickly per-unit costs increase with an increase in production
- if increased production requires much higher costs, the supply curve will be inelastic
- if production can increase with constant costs, the supply curve will be elastic
~ how cost efficient= how elastic
- ## the time horizon
Pe
Equilibrium price
Qd
Quantity demanded
Qs
Quantity supplied
What happens at the Pe?
At the equilibrium price, consumers want a certain number of an item while all the producers are willing to supply at that number.
- No producer or consumer willing to deal at that market price goes home unhappy
What happens when the market price is above the equilibrium price?
A surplus occurs.
MP
Market price
What happens when the market price is below the equilibrium price?
A shortage occurs.
Qe
What happens there?
Equilibrium quantity
Qs=Qd
- market is cleared
- no consumers ready to buy the product at the Pe goes home empty-handed and no producers willing to sell their product at the Pe don’t sell their entire stock
How to find surplus and shortage on a graph?
At the price below/ above the Pe, the gap between the two points on the two curves is the surplus/ shortage.
Under what assumption is the supply schedule constructed? What does the supply schedule show us?
assuming all other factors that could influence supply apart from price remain constant- ceteris paribus
- shows the quantity of a good that will be supplied over a range of prices at a given point in time
How is the market supply schedule formed?
Derived from the summation of all the supply schedules of the individual firms that operate in the industry.
Why does the law of supply occur?
- For firms already in the industry, producing the good becomes more profitable, so they increase their production of good
- The higher price also makes producing this good more profitable for other businesses, which will attract new firms into the industry. This will also cause an increase in the quantity supplied.
Describe the supply curve.
Price in y axis, quantity in x axis.
- typically a growing curve
- more is supplied at a higher price, less is supplied at a lower price
Contractions of supply
When a decrease in the price of a good or service causes the quantity of goods and services supplied.
- downward movement along curve
