Ron,
When I was in school, "Economics" was thought of as a "social science", not a hard science like Physics, but a softer one like Sociology.
In that sense, it was always much more challenging to me to concertize an economic truth, as economic experimentation seemed more imponderable than, for example, analyzing chemicals in a laboratory, and then arriving at some firm hypothesis.
We can put a man on the moon, but can we send Tyhee's share price into outer space?
