Midterm 2 Flashcards
budget constraint (or budget line)
shows the possible combinations of two goods that are affordable given a consumer’s limited income
total utility
the satisfaction a consumer gets from consuming some quantity of a good or service; also, it’s the total satisfaction from consuming all the goods and services an individual purchases.
utility
the term economists use to describe the satisfaction or happiness a person gets from consuming a good or service.
calculate marginal utility
MU=change in total utility/change in quantity
diminishing marginal utility
the common pattern that each marginal unit of a good consumed provides less of an addition to utility than the previous unit
marginal utility
the additional utility provided by one additional unit of consumption
calculate marginal utility per dollar
marginal utility per dollar=marginal utility/price
consumer equilibrium
the combination of goods and services that will maximize an individual’s total utility
marginal utility per dollar
the additional satisfaction gained from purchasing a good given the price of the product; MU/Price
factors of production (or inputs)
resources that firms use to produce their products, for example, labor and capital
firm
an organization that combines inputs of labor, capital, land, and raw or finished component materials to produce outputs.
production
the process of combining inputs to produce outputs, ideally of a value greater than the value of the inputs
Marginal product
additional output of one more worker;
MP=ΔTP/ΔL
fixed inputs
factors of production that can’t be easily increased or decreased in a short period of time
long run
period of time during which all of the firm’s inputs are variable
production function
mathematical equation that tells how much output a firm can produce with given amounts of inputs
short run
period of time during which at least one or more of the firm’s inputs is fixed
variable inputs
factors of production that a firm can easily increase or decrease in a short period of time
profit
the difference between total revenues and total costs
Profit = Total Revenue – Total Cost
calculate Total Revenue
Total Revenue = Price x Quantity
accounting profit
total revenues minus explicit costs, including depreciation
economic profit
total revenues minus total costs (explicit plus implicit costs)
explicit costs
out-of-pocket costs for a firm, for example, payments for wages and salaries, rent, or materials
implicit costs
opportunity cost of resources already owned by the firm and used in business, for example, expanding a factory onto land already owned
