Extensive and intensive margins
The definitions of “extensive margin” and “intensive margin” presently in the article seem to be founded in confusion, and (after looking) I have not found them similarly defined elsewhere.

Rather, the traditional definition of “extensive margin” is that it measures how many units of some resource are in use, while the “intensive margin” refers to how hard those units are being worked. For example, if Joe is being paid to be at work for 8 hours, then we have his extensive margin. If we increase how much Joe must produce per hour, then we have changed the intensive margin.

Someone seems to have misinterpretted an illustrative example in which extensions were presented with integral values, and intensions seemed continuous. But Joe could contract to work any possible length of time, and the intensity with which a resource could be used might actually be intrinsically discrete.

I have fact-tagged the questionable definitions, but I will replace the definitions in a matter of days if support isn't provided for them. —SlamDiego&#8592;T 08:26, 7 October 2008 (UTC)
