In my opinion, taxing black money is the most important issue. Efficiency and progressivity are secondary, in my opinion. Additionally, as discussed, government would not allow perfection in an APT-world.
An admirable goal, but I feel a foolish one. The history of ciminal activity is such that they always find ways to beat the system. As I stated before, criminals often prove far more innovative than governments. No doubt you will pick up some of those basically honest folks participating in an underground economy but the big money comes from big players and they are not inclined to let a new fangled tax methodology get in the way of ill-gotten gain.
To me, progressivity is paramount in a tax system. Efficiency is a good thing and should be sought but is very difficult to attain. I do agree that governments are unlikely to adopt any tax system without fiddling with it, now or later.
I do not see any problem in implementing subsidies under an APT-world. The APT just limits how people are taxed, not how government spends the money. In this sense, an APT-world would be fairer, since it would allow to determine more precisely who deserves a subsidy and who does not. Many people live under black money currently, and they are legally eligible for subsidies. This is unfair. Electronic money would make much more difficult to claim poverty under richness.
The government could simply send cash to the poor people, irrespective of taxes.
Have to connect the dots. One of the predicates for APT, one of its big promotion points, is the elimination of the IRS. The argument goes that we save all the money that an IRS agency costs us and we save all the money and time spent on filing a broad assortment of income and tax returns. There is no longer any payroll reporting, no tax returns, no data collection for determining who makes how much or how they spend it. Dr. Feige envisions no traceability in the tax collection process under APT other than the debits and the credits. No detail behind the transactions. This then means we have no knowledge and no way of computing who needs what subsidies and who qualifies for those subsidies. We could set up a postcard system where the poor send in a postcard claiming eligibility for that cash (what happened to eliminating cash?) and then disbursements could be made. You will find out in short order that there are a lot more poor people out there than you thought.
I realize that you are conceptualizing but you need to establish a coherent, interrelated framework that addresses the various factors and ties them all together. Dr. Feige has done this well but he is an academic and much of what he laid out is I'm sure based on his many years of thinking and dealing with these issues. My recollection is that even he fails to address just how the economic information is to be collected to allow various social welfare spending to be effected.
In comparison to the cost of police, army, jurisdiction, ... a fee for transaction would be very low. Additionally, in Spain at least, debit card transactions are free (credit cards are not).
Are you proposing that an APT taxing system will eliminate police and armies and the need for jurisdictions. That they will all just disappear? Might be considered a slight stretch. In the US charges for debit card transactions are all over the place. Certain transactional situations incur fees, others do not. Credit cards, for the most part, are free of any annual fees, but there are a plethora of intermediate fees that pop up; including interest charges. Since I carry around little cash at one time, my risk of loss is far less than if I were carrying a card which allowed access to all the funds I may have.
Barter would be the only option, but barter is inefficient, especially with a lowish tax rate.
Aha! One of my favorites. Barter can be inefficient for individuals, although its use is not that rare. Barter for businesses is far from inefficient depending on the circumstances. I have, somewhere in this morass of writing I have done here, a dissertation on barter possibilities for businesses. It points out that barter by businesses can often be carried out in the same manner as a normal business transaction between two parties. No inefficencies and no interruptions to the normal flow of goods and services. Even Dr. Feige pooh-poohs barter as a viable option which, to me, exhibits a tendency to be unfamiliar with the real world. I have also reflected that while transactionally the APT tax rate is low (lower than yours), cumulatively it adds up and will motivate businesses to pursue avoidance measures.
Innovative ideas are manna for we naysayers.
