Econ Midterm 2 Chap. 6-10 Flashcards
Accounting Profit
Calculated by subtracting the explicit costs from the total revenue
Diminishing Marginal Product
Occurs when successive inputs are associated with a slower rise in output
Economic profit
Calculated by subtracting both the explicit costs and implicit costs of doing business from total revenue
Explicit Costs
Tangible out of pocket expenses
Factors of production
The inputs (labor, land, and capital) used in producing goods and services
Fixed costs
Unavoidable; do not very with output in the short run.
Fixed inputs
Inputs that cannot be changed in the short run
Implicit Costs
Opportunity costs of using resources already owned for one purpose rather than another
Loss
When total revenue is less than total cost
Marginal Cost
The increase in cost that occurs from producing one additional unit of output
Marginal Product
The change in output associated with one additional unit of input
Marginal Revenue
The additional revenue generated by the production and sale of one more unit of output
Output
The good or service a firm produces
Production Function
Describes the relationship between inputs and outputs
Profit
Results when total revenue is higher than total cost
The profit-maximizing rule
States that profit maximization occurs when the firm chooses the quantity causes marginal revenue to equal marginal cost (MR=MC)
Total Cost
The amount a firm spends to sell/produce a good or service
Total output
The sum of the individual worker’s marginal products
Total Revenue
The amount a firm receives from the sale of goods or services
Variable Costs
Costs that change with the rate of output
Variable Inputs
Inputs that can be changed quickly to increase or decrease output levels.
Average Total Cost
The total cost of producing a particular amount of output, divided by the amount of output
Barriers to entry
restrictions that make it difficult for new firms to enter the market
Competitive Market
Exists when there are so many buyers and sellers that each has only a small (negligible) on the market price and output
Market Power
Refers to a firms ability to influence the price of a good or service
Market Structure
Refers to the way firms in a particular market are interconnected
Price Taker
Has no control over the price set by the market. It “takes” (accepts) the price determined from the overall supply and demand conditions that regulate the market
Signals
