2.2 Supply Flashcards
What is supply
Quantity of goods and services a firm/producer is willing and able to supply to the market for sale at different possible prices, during a particular time period
Law of supply
Positive relationship between the quantity of a good supplied and its price
As the price of a good increases, quantity supplied also increases
individual supply
supply of one product from one firm at every price
Market supply
The sum of all individual supplies of a product at every price
law of diminishing marginal returns
adding more of one factor of production, while holding at least one other factor of production constant, will at some point yield lower marginal returns
marginal returns
additional output gained from adding an additional unit of input to a production process
Marginal cost
the cost of producing one more unit of a good
What are the non price determinants of supply
cost of factors of production
increases in technology
prices of related goods (competitive supply + joint supply)
producer price expectations
taxes
subsidies
the number of firms
Explain the non-price determinant of the costs of factors of production
If factor prices rise, production costs increase, production becomes less profitable and firm decreases supply
Explain the non-price determinant of improvements in technology
Improved technology lowers production costs, making production more profitable, increasing supply
Explain the non-price determinant of competitive supply
Refers to the production of one good or another good by a producer
A fall in price in good A, results in an increase in good B supply, as it is now more profitable
Explain the non-price determinant of joint supply
Refers to production of goods that are derives from a single product
Increase in price of Good A, leads to increase in its quantity supplied and also an increase in supply of the other joint products
Explain the non-price determinant of producer price expectations
If firms expect the price of their products to rise, they may withhold some supply expecting that they are able to sell it for a higher price, decreasing supply
Explain the non-price determinant of taxes
When taxes are imposed, firms cost of production increases, so supply will decrease
Explain the non-price determinant of subsidy
Imposition of subsidy, lowers the production costs, increasing supply
