This week's market:

This post is a response to QXLOp's article and I was originally writing it out as a comment but found it it's becoming too long that it really deserves its own post.

With the lack of economic tools in congress, a rough way to measure effects of taxation would be:
1) Log every day how much went to PH government coffers for about a week (week 1)
2) Pass law to adjust a single tax rate by 1%
3) Measure PH government income for another week (week 2)
4) Pass law to undo 2
5) Measure PH government income for another week (week 3)
6) re-pass law #2
7) Measure PH government income for another week (week 4)
8 ) Repeat, adjust tax rate in another area

In theory, week 2 and week 4 would have increased revenues as an effect of the increase in taxation. In practice, of course, this is not as simple. Numerous forces (e.g. wars, changes in supply and demand, world market, adjustment crossing a threshold, etc.) influence buying/selling behavior.

What do you think? Is it worth the effort to do this activity knowing that we risk gathering false data? Do you know of any tool out there?
