four factors of production

land, labor, capital, entrepreneurship

land

all natural resources used to produce goods and services (water, sun, plants, animals, etc)

labor

investment

the money spend by businesses to improve their production usually by increasing their capital

consumer goods

capital goods

Three Economics Questions

What to produce? How to produce? For whom to produce?

economic system

the method used by a society to produce and distribute goods and services

command economy

transfer payments

Benefits given by the government directly to individuals. Transfer payments may be either cash transfers, such as Social Security payments and retirement payments to former government employees, or in-kind transfers, such as food stamps and low-interest loans for college education.

Subsidies

a sum of money granted by the government or a public body to assist an industry or business so that the price of a commodity or service may remain low or competitive.

production possibilities curve

a graph that shows alternative ways to use an economy's productive resources

constant opportunity cost

Resources are easily adaptable for producing either good

increasing opportunity cost

the opportunity cost of producing additional units of a good rises as society produces more of that good

decreasing opportunity cost

having to give up an ever decreasing amount of one good to get additional units of another

Three shifters of the PPC

1.change in resource quantity or quality, 2. change in technology, 3. change in trade

absolute advantage

the ability to produce a good using fewer inputs than another producer

comparative advantage

the ability to produce a good at a lower opportunity cost than another producer

terms of trade

the ratio at which a country can trade its exports for imports from other countries

output questions

OOO-Output: Other goes Over

input questions

IOU- Input: Other goes Under

explicit costs

The actual payments a firm makes to its factors of production and other suppliers.

implicit costs

Indirect, non-purchased, or opportunity costs of resources provided by the entrepreneur

cost benefit analysis

a study that compares the costs and benefits to society of providing a public good

law of diminishing marginal utility

the principle that consumers experience diminishing additional satisfaction as they consume more of a good or service during a given period of time

marginal utility

an additional amount of satisfaction (Utility = Satisfaction)

utility maximizing rule

The principle that to obtain the greatest utility, the consumer should allocate money income so that the last dollar spent on each good or service yields the same marginal utility.
