To an economist, real life is a special case.
An economist is a person who confronted with an eight foot high wall, immediately assumes he is ten feet tall.
I begin with the assumption that economists have their uses. I know many of you will disagree with this, but as economists themselves say, ‘we can relax the assumption later’.
A physicist, a chemist and an economist are stranded on an island, with nothing to eat. A can of soup washes ashore. The physicist says:
“Lets smash the can open with a rock.”
The chemist says:
“Let’s build a fire and heat the can first.”
The economist says:
“Lets assume that we have a can-opener”.
