If this is really a good thing (tm) then perhaps the best incubator to test the theory in a 'crucible of experiment' would be in corporate governance. As more corporations move towards QV (with, hopefully, good results) it may find its way into political public policy.

The paper mentions that efficiency of quadratic voting only kicks in with larger numbers of participants (> 50).

The equity issues you all are raising are very important, but death with in detail here: http://papers.ssrn.com/sol3/papers.cfm?abstract_id=2343956. The simplest solution is just to use an artificial currency that everyone is given equal amounts of but can spread over the decisions most important to them. In this piece with Rory Sutherland we discuss this: http://www.spectator.co.uk/features/9512322/humans-are-doing...

Just reading the linked summary (and not the paper itself), it seems like this doesn't take wealth disparity into account. If the cost for your votes is the square of the votes you want to cast, then that means people with a lot of money can trivially buy significantly more votes than people with very little money, even if they don't necessarily care more about the issue than the people with very little money. It see…

As paper describes, quadratic is the unique function with linear derivative and thus the only one that reveals true preferences.

How does this system deal with the logarithmic value of dollars, and the asymmetry in who has them? When you get ln(X) happiness from X dollars, you are sacrificing 1/X happiness per dollar spent. A billionaire buying a thousand votes is paying ln(10^9 - (10^3)^2) - ln(10^9) ~= 1 milli-utilon, but a thousandaire buying ten votes is paying ln(10^3 - 10^2) - ln(10^3) ~= 100 milli-utilons. It seems like billionaires, wh…

Billionares are vastly outnumbered by thousandaires. For example, in an FPTP election their ability to buy 31600 votes would, nationally, let them move the 50 yard line, towards which politics converges, 0.001% to the left or right.

The paper has examples with dollar amounts starting around page 30. If ten thousand poor people buy one vote each for $1, the wealthy would-be tyrant needs to buy 10,001 votes to win, at a cost of $100,020,001. If the tyrant goes ahead and does this, after the election all the poor people will receive $10,001 each.

And so? My $100m made me lord tyrant ruler of the universe. Is existing inequality enough that quadratic voting realistically dismantles rather than reinforces existing power structures?

Has QV been used in any practical context? If so, I'd welcome replies as I didn't pick up on this.

It would probably be cheaper for the would-be tyrant to just promise $5000 to each of the poor people (not necessarily in cash - i.e. "if I am elected I will institute a new support program for the people with the budget of $5000 per capita", etc.) - that's how it is done nowdays and works quite frequently.

Distributing the money to other electors gives them a lot more voting power in the subsequent election. Edit: unless that makes wage-earners negotiate to less income.

The thing is, we already have the tyranny of the wealthy. The Tullock paradox is basically that the cost of lobbying is dwarfed by the returns.

https://en.wikipedia.org/wiki/Tullock_paradox

I'm still getting my head around it, but it seems that Quadratic Voting would actually increase what wealthy people pay to influence public policy.

Edit: Just as an example, the largest "outside money" spender in the 2012 election was Crossroads, which spent about $57M. I have no idea how many votes they were able to get for that money. With Quadratic Voting, they'd get 7,550. That doesn't seem unreasonable to me.
