The axiom of human action and the laws of economics
Unlike natural science, that experiments are possible but then we have only the best guess possible in Throughout, the economy is based on the axiom of human action to derive their general and immutable principles . He says:
The man acts always and everywhere to improve their situation. This does not mean it always holds good reason, take wise decisions and have the best information available. But taking into account the values informacióny it does, seek to move from a less satisfactory to more satisfactory. Human action, then, is a deliberate attempt, which involves costs (including alternative sacrifice) as time and effort, which involves the use of certain means to search for the uses proposed and finally, you can have and success or failure.
This statement is an axiom as true not only easy to verify (as we are human beings) but that can not be successfully refuted. Ie if someone wants to contradict that "humans act" and all the implications outlined above, is in itself a human action. Would thus validating the axiom with its own intent.
and the axiom of human action can be deduced then the laws of economics, either because they are involved directly or they may be derived from it.
An example:
The Law of Demand: If nothing else changes and the price of a good rises, demand will be equal to or less but never more.
We know that this principle of economics is true if and wherever human beings because they never act against their best interests, such as perceived. Buy something more expensive or when it becomes more expensive, well-being exactly the same, mean just that.
Another example:
Exchange Principle: Two people make an exchange as both value most what they can get from another what they had before swapping.
Again, since both have been forced to exchange (for a mob or a government), we safely conclude that both expected, ex ante at least benefit from the exchange.
course, not all laws and principles of economics can be derived from the axiom of human action. We must add at least three observations about the world in which human action takes place in order to advance our understanding of economic phenomena.
First:
innate and acquired differences exist among all human beings.
Moreover, humans do not all have the same genetic characteristics inherited or personal environments have lived in the same or identical cultures. It turns out that there are marked differences in talents, interests and tastes among humans.
This observation additionally monumental philosophical implications. Since humans are not interchangeable for each other in the same way they are ants or bees, freedom is an essentially human and the mere recognition that we are all unique individuals and unique.
The second:
natural resources around us are different.
is very important to add this observation, our concepts of natural resources as if they were the same, the motivation for trade between different regions and countries would be diminished or nonexistent.
Third:
The real world is a world of scarcity.
Even in the Garden of Eden, Adam will find that you can not eat of every tree at the same time, neither can take a nap and swim at the same time. That is, you have to economize the use of resources, including time. In the real world, scarcity is a fact in almost all respects.
