Economics Ch. 5: Supply

What factors can cause a change in supply? (2 card set!) Describe them.

1) Costs of input: If it costs more to produce a good, then the supply will increase. 2) Productivity: If workers are willing to produce more, than supply increases. Happy workers are more productive. 3) Technology: New machines, chemicals, and programs can cause an increase of productivity. 4) Taxes: Taxes cause the cost of production to go up, causing a decrease in demand.

What are the four key measures of cost? (FVTM)

1) Fixed cost: costs that do not change much: salaries, rent, and taxes. 2) Variable cost: the change that occurs when output changes. eg: electric power, shipping charges, new machines, etc. 3) Total cost: The sum of fixed and variable costs. 4) Marginal cost: Costs from extra production

5) Subsidies: The opposite of taxes- a government payment to protect an industry. This cause an increase in production. 6) Expectations: If a producer expects a product to be in demand, they will increase supply. During winter, clothing manufacturers expect to sell more coats, so they supply more coats.

What is revenue?

Revenue is the total number of units sold multiplied by the cost of each unit. Selling 10 hats at $6.00 each gives a revenue of $60.

The higher a price that a seller can sell a good at, the greater the quantity the seller will supply.
