OTOH, it might help with our aggregate demand problems.
It's quite possible I'm missing something, however.
Let me put it this way. If you were the only grocer[1] in the neighborhood and you knew that everyone in the neighborhood just got a 10k raise, would you not consider raising prices? Or, put another way, if you're the only grocer in the neighborhood, and everyone gets 10k/yr of free money, and that induces, say, 10% of your workforce to quit for various reasons, then you have to pay more for labor and pass the costs to customers. Either way, food prices rise.
[1] Note, that's not improbable in many poor areas.
[2] I'm just armchair speculating here... so, like I said, I could be way off base.
If you assume a totally monopolistic marketplace (so that there is no competition to drive down prices but instead there is unlimited capacity to extract monopoly rents), sure. In a marketplace with any kind of competition you'd expect some increase in each the market clearing price and the market clearing quantity of each of the goods that would be purchased by the people who end up with a greater net income after the policy change.
Because if that's done with basic necessitate like food so people are force to starve because corporations want to charge as much as possible they should all be charged with the death penalty.
An interesting side effect might be an increase in the ability of people who work to extract the value of their work from people that hold capital.
However, when rent prices go up, it encourages people to build more homes/apartments which in turn drives prices down. There is a feedback loop (granted, many times it's interrupted, and there is a delay)
As a result the money supply does not increase. If any inflation occurs, it is caused solely by a shift of spending from goods/investments not measured by CPI (or the swiss equivalent) to those that are.
(I.e., if money shifts from investment in electronics research to pizza consumption, the price of pizza will rise and the price of of oscilloscopes will fall. Since CPI includes the price of pizza but not oscilloscopes, inflation will rise.)
