What is the importance of Specialization in Production?
- Specialization in production allows workers to become more efficient.
Perfectly inelastic supply curve is
- a vertical line - Ep = 0
Quantity supplied definition
- amount of a good a firm is willing or able to sell at a given price
Change in supply refers to
- amount of supply offered by sellers - affected by many variables - leads to shifts in supply curve
Which combinations on the PPF are efficient? Why?
- combinations ON the PPF - because they use all available resources and the fewest amount of possible resources to produce a given output
Production Possibility Frontier (PPF)
- curve showing the maximum attainable combinations of two goods that can be produced with available resources
supply curve definition
- graph plotting the supply schedule
Price of Related Goods
- if price of substitute increases the supply of alternative good decreases - if price of substitute decreases, the supply of alternative increases - if price of compliment increases supply for both increase - if price of compliment decreases supply for both decrease
price elasticity of supply
- measures responsiveness of change in quantity supplied to a change in price
Change in quantity supplied refers to
- movement along the supply curve - refers to changes in prices
supply definition
- number of units a seller is willing to offer for sale at various prices.
Positive Technological Change
- occurs when a firm can produce a larger number of outputs using the same number of inputs - increases productivity - shifts curve right
Negative Technological Change
- occurs when a firms produces a less amount of output using the same number of inputs - productivity decreases - shifts supply curve left
Increasing Marginal Opportunity Cost
- occurs when you move down the PPF when it is bowed out - an increase in one good requires larger and larger decreases in the other good because some workers and resources are better equipped for the "other" good.
Economic Growth
- outwards shift in the PPF - allows the economy to increase production of goods increasing the standard of living.
Dynamic efficiency
- resources are allocated over a period of time.
Combined, what do increased capital and innovations do to the PPF and opportunity cost?
- shifts the PPF outward - drives down opportunity cost
law of supply definition
- states that holding all else constant, the increase in the price of a product will lead to an increase in the quantity supplied, and the decrease in the price of a product will lead to a decrease in the quantity supplied
supply schedule definition
- table showing the relationship between price of the product and the quantity supplied
Comparative Advantage
- when an individual/firm has the ability to produce a good at a lower opportunity cost than competitors.
Absolute Advantage
- when an individual/firm has the ability to produce more of a good than competitors using the same amount of resources
Prices of Input
- when price of input increases, the cost of production increases, and the supply will decrease shifting curve left - when price of input decreases, cost of production decreases, and the supply will increase shifting supply curve right
