Governments are in a privileged position to get this data and they likely have it and have reasonable models. The classic knob to influence inflation is interest rates. This can be also be modeled. Non-politicised civil servants have a good record of being able to do a reasonable job at this - only if the politics are removed. In my opinion, removing all political allegiance for civil servant agencies is probably the best way to get better long term stability and prosperity.
