Chapter 1 Flashcards
Economics
the study of the choices that society makes given the scarce resources avilable
Choice
- What gets produced? What goods and services?
- How is it produced? What production techniques are used?
- Who gets what is produced? Distribution of goods and services throughout society
Scarcity
the notion that there are unlimited wants but resources are limited; How does society deal with that?
Why study economics?
- to understand society & economic decisions that are made influence society
- to learn a way of thinking
- to understand global affairs to better understand relationships between countries
- to be a more informed citizen
People are rational
we assume people make decisions using all available information
People respond to economic incentives
money talks; bank robbery example: take risk of getting robbed over hiring a body guard
Optimal decisions are made at the margin
- a marginal change refers to a small incremental change in the total; ie: marginal cost = small change in the total cost
- optimal decision making tells us that an activity will continue until marginal cost = marginal benefit
Sunkcosts
- costs that cannot be avoided b/c they have already been incurred; ie. desk clerk at a hotel still going to work regardless if a room gets rented
- sunkcosts are irrevelant to decision making
Opportunity Cost
- the next best alternative that we forgo when we make a decision; does not refer to the sum of all alternatives, just the next best alternative
- the total cost includes the implicit or opportuniy cost + the explicit cost (ie. cost to go to Saint Anselm College for 1 year)
Trade-offs
every decision that we make involves giving up something else b/c we face scarcity
Centrally Planned Economy
government makes all decisions; ie. North Korea; not very successful in producing low cost high quality goods which results in low standard of living
Market Economy
households and firms make decisions; not the government
Mixed Economy
households, firms and government all plays a role in decisions
Efficiency
society getting the most that it can from its scarce resources; markets are generally efficient b/c they tend to promote competition and voluntary exchange
Voluntary Exchange
the buyer and seller are both made better off by the transaction
