CH 1: Principles of Econ Flashcards
Economics
The study of choices that individuals make given the presence of scarcity
Scarcity
Limited resources but unlimited wants
Scarcity vs. poverty
Poverty is comparing someone’s wealth to a subjective threshold value vs. how everyone faces limited resources
The Six Types of Resources
Land, nonhuman animal resources, labor (physical & mental human capital), capital, technology, & entrepreneurial ability
Capital
Resources, produced using land and labor, to use for further production
Economy
The institutional structure through which individuals in a society coordinate their diverse wants
The three questions economies must answer…
1) What should we produce and how much? 2) How will we produce? 3) for whom do we produce?
Efficiency
The property of sciety getting the most out of its resources
Rational People
Systemically and purposefully do the best they can to achieve their objectives (by weighing costs and benefits AND thinking at the margin)
Sunk cost
Has already been incurred and cannot be recovered
Economic decision rule
If the marginal (incremental/additional UNIT) benefit of the action exceeds the marginal (incremental) cost, do it. If the MC > MB, then don’t do it.
Five facts about trade
1) NOT a zero sum game
2) Trade creates value for participants (b/c they wanted them most) and increases wealth by the society’s resources
3) Transaction costs can inhibit trade
4) The middleman reduces costs
5) As trade restrictions are lifted, more value is created from trade
Market Economy
An economy that allocates resources through the decentralized decisions of many firms and households as they interact in market for good and services
The invisible hand
The price mechanism guiding economic forces to coordinate actions and allocate resources, influencing prices in a market context of buyers and sellers
Adam Smith
Economist who coined “invisible hand”
Invisible Handshake
Social and historical forces and cultural norms that influence market outcomes
