Well, I don't know but I am guessing that none of us are Entreprenuers or inventors, etc.
I got to a job - I make X dollars. I want a certain life so I have to make a certain dollars. If my taxes go up - then I have to cut spending because at this point I just can't make more dollars. There are simply not enough hours in the day.
However, if I were a business owner, or if I were self employed, I may very well make a decision to work less or to not expand the business. But, none of those things are relative to me as an employee who makes a certain salary.
A lot of my clients who are business owners though, do make decisions such as slowing down or closing operations or not expanding operations based on their tax liability as a whole. They will definitely make decisions to take advantage of certain tax deductions. For instance, when they raised the limit of what you could write off in one year and offer "bonus" depreciation as long as the equipment is brand new, people went out and bought brand new equipment instead of 2 or three year old equipment so they could get a bigger write off.
But, those things are not relative to me as an employee whose income is "fixed". For people like me - paying more in taxes means I have less money to spend on other things. Since the economy is based on people spending - I can't see it is a good thing for the economy to have me wanting to spend less.
And, while raising taxes may not have an immediate effect of causing people to "work less" doesn't mean you can discount the impact of offering specialty credits and deductions can have on spurring certain behaviours. And, those credits and deductions are nothing more than tax decreases.
I think the issue at hand is that - no an accross the board even tax increase will probably have little to no effect on production. It will have an effect on spending. Which over time could lead to decreased production. However, offering specialty credits and deductions designed to encourage certain behaviors - such as spending on new homes, and buying new pieces of equipment ( which translate into booms for certain industries) does have a pretty immediate impact on behavior. And, since those specialty deductions are nothing more than tax reductions, then they do have a positive impact on the economy because people will then do things particularly to take advantage of those credits.
