Economics: Basic Concepts
Economics: Broad Definition
-
How people organize
-
to meet their material needs
Economics: Narrower Definition
-
How society
-
allocates resources and
-
distributes goods and services
An economic system
-
turns resources into goods and services -- allocation
-
and gives them out to people to use -- distribution
Goods and services
-
useful things
-
Goods:
-
tangible
-
usually physical objects
-
Services:
-
intangible
-
what a person does for you
Resources
-
Things that can be used to make other things. Inputs into production.
-
Resources can be
-
tangible, like a lump of coal, or
-
intangible,
-
like an hour of your labor
-
or some knowledge you have
Resource types
-
Labor
-
Natural resources
-
things found in nature in raw form
-
Capital
-
things people make to help make other things
Capital
-
Capital is anything that people produce that is then used to make other
things.
-
This is different from the business usage, where capital refers to
money.
Capital
-
In economics, capital can be
-
equipment,
-
machines,
-
buildings,
-
intermediate goods, like steel beams used later to build a building,
-
knowledge, developed through experience or education,
-
human physical ability developed through exercise.
The relationship between the economics and the business usages of
"capital"
-
To start an enterprise, you first need to have equipment, buildings,
etc.,
before you can sell anything and bring money in.
-
You need to have "capital" (business usage) up front
to pay for your capital (economics usage).
Investment
-
Economics usage: Investment = Adding to capital.
-
Compare business: spending money in return for claim on future income.
-
Generally, investment in the economics sense requires investment in the
business sense.
Investment examples
-
Building a building
-
Installing a machine

Classical economists had three categories
-
Economists in the early 1800s had separate categories
for
-
Labor
-
Capital
-
Land
-
My "natural resources" category is a generalization of Land.
Natural resources and capital -- the same?
-
Since natural resources have to be worked on to be useful
-
(e.g. oil has to be found and then pumped out of the
ground),
-
some economists just use two categories of resources,
capital and labor.
- But it is useful to distinguish something that can be reproduced (capital) and something that can't (land and other natural resources).
The world's oil production may peak in the next couple of years.
Health can be regarded as capital
-
Capital is whatever people make to help them make other things.
-
Having health helps a person make things, so health is capital.
Health care -- a consumption good and an investment good
Health care is purchased to enhance health.
-
Health enhances our enjoyment of life. Health care is a consumption good.
- Health enhances labor productivity. Health care is an investment good.
An investment is any action that increases capital, including human
capital. Abilities (physical or mental) that human beings develop are human capital.
Health Care, Resources, and Production
-
Health care uses resources, as all goods and services do.
-
Health care also adds to resources, to the extent that it adds to human
capital.
-
The total supply of resources that society has puts a limit on what
that
society can do.
-
given the technology and the efficiency of the system
-
Health care affects, positively and negatively, the total capacity of
the
economic system to satisfy human wants.
This is our segue to discussing the central issue of economics: "The
Economic
Problem"
The Economic Problem
-
Resources are scarce, relative to human wants for goods and services.
-
Therefore, decisions must be made on how to
-
allocate resources and
-
distribute finished goods and services.
The Economic Problem in two words:
Allocation and Distribution
-
Allocation
-
decide which resources are used
-
in what ways
-
to produce which goods and services.
-
Distribution
-
decide which goods and services go to which people -- who gets what
-
also, which jobs go to which people -- who does what
Economics helps us make allocation and distribution decisions better.
-
Individual decisions -- what's best in my situation?
- Picking the best investment, for example
-
Social decisions -- what institutions best encourage good decisions?
- Competition vs. regulation, for example
Table of terms for the goals of economics
In the U.S. health care system, scarcity is manifested as
-
Limited access to health care for many people
-
The health care system swallows up a large portion of national
resources, limiting how much of other good things we can have.
-
16% of U.S. gross domestic product goes to health spending, the highest
percentage of any country
-
Canada is a distant second, at 11%.
- What do we get, that other countries don't, for the extra we
spend?
High expenditure would not be bad, were it not for the suspicion that
-
We're paying too much for the health care we get.
-
We're not getting the best mix of goods and services that
we could for the resources we put in.
- Some people get more than they need, while others get less.
Let's go over each of these points in turn:
- We're paying too much for what we get
-
an issue of allocation between the health care system and the rest of
the
economy
- We're not getting the best mix of goods and services that we could
for
the resources we put in.
-
an issue of allocation within the health care system
- Some people get more than they need, while others get less
-
an issue of distributional equity
Problems with how we solve the Economic Problem
-
We overcompensate some providers, and underpay others
-
Our administrative costs exceed any other country's
-
Yet our system invites fraud and abuse
-
We over treat some while excluding others
