What is the difference between this two kinds of calculations of elacisity??? Since Arc one calculates the average of the coefficient, wut is the advantage???? And under wut situation should i use arc or point?????? Get Serious...I was confused....
I donno whether there is true economists here or just general discussors.....I was surprised that no one so far can answer this basic theoratical economic questions.... =.=
try http://groups.google.com/groups?hl=en&lr=&group=sci.econ. There are lots of "semi-, professional" economists hanging out there.
