I have proposed a way to control inflation.

1. For the sector of interest, require vendors to advertise price changes from one week in advance. They must also advertise the change for one week after the price has changed. For retail this means changing shelf labels.

2. vendors must also list the markup and the price peer kilogram.

3. any price change greater than a limit, for example 5% per week, requires informing the regulator and paying a fine.

4. Prices must be submitted to a searchable online database.

5. loyalty cards and other discount vouchers are forbidden.

Now for a normal economy, these measures all affect various limitations of a competitive market, discouraging profiteering and inflation. But could this also work to correct runway inflation?

Is there any other plan that could work?
