Economists in business usually act to perform one or more of three functions. These are (list):
1. figure out how to MAXIMISE THE RETURNS of the organization or ourselves within our constraints
2. figure out how to MINIMISE THE HARM that others can do to us
3. help us reshape the way things are done so that BETTER OUTCOMES RESULT
The main observation of economics is the problem of scarcity. Scarcity is best described as:
Insufficiency. There are infinite needs and wants and only finite resources.
What are the two main economic questions?
What is the best way to use scarce resources? - Nominative Questions
How economic principles are being used at the moment? - Positive Analysis (looking at what we are doing, and how we can do it better/achieve more economic outcomes)
Describe the economic concept of Homo Economicus-
Economists believe it is essential to not underestimate the degree to which nearly all economic agents will act to increase their material welfare. Thus the behavioral model of Homo Economicus, where someone rationally maximises their own material welfare. Thus economics was defined early as the science of human behavior resulting from wealth maximization, by John Stuart Mill (1844) and Stanley Jevons (1872).
As mentioned, the IMMUTABILITY of material motivations cannot be cast aside in economic behavioral analysis. While, in times of crisis, people may forgo material wants in place of ideological philosophies alone, economists believe this is not a sustainable motivation.
Thus, the homo economicus enables us to predict behavior by using it as a model.
Who is said to be the father of economics?
Adam Smith (1776)

The Invisible Hand?
The invisible hand of the market is the tendency of prices to move toward a situation where noones situation/position can be improved by further undercutting.
It is a lot about private vices producing social outcomes.
'it is not from the benevolence of the butcher, the brewer or the baker, that we receive our dinner, but from their regard to their own interest' - Adam Smith (1774)
Functioning Markets are a requirement for competition. Competition works when Markets function around 3 key concepts discussed, these are:
- there are MANY SELLERS
- buyers and sellers are INFORMED
- neither buyers nor sellers coordinate OR COLLUDE to defraud others
A result of the Invisible Hand of the market is Specialisation.
Specialisation results when prices are ________ and the market then becomes more _________ and people do what they do relatively ________.
stable, efficient, best
Benevolent Rule Setters- The 'King' is seen as interested in the common good and also as non partisan.
In economics, if these 'kings' are not interested in the common good:
state capture, state failure or corruption results.
Equilibrium is attributed to:
Leon Walras (1874)
An economic system is said to be in equilibrium when:
- it is not possible to improve on anyones outcome by changing their behavior.
- all opportunities for gain are exhausted
- every one CAN do what he or she wants to get the market to equilibrium
- everybody has as much information as possible
The market is always moving towards the most 'efficient' point of:
Economic Rationality is:
that homo economicus is a fairly good calculator

a continuous stream of shocks and discoveries (e.g. technological innovations) constantly creates new opportunities and closes down old ways of doing things.
