Recent research into monetary policy has looked for interest rate rules that ensure price level determinacy independently of the fiscal policy of the government; this has weakened interest in the FTPL. Though no issue as controversial as the FTPL has emerged since, this recent analysis is still open to ambiguous distinctions between policy rules, that should capture government behavior in all possible scenarios, and equilibrium relations across the endogenous variables of an economic system. A more complete analysis awaits the development of new tools that are as simple and powerful as dynamic competitive equilibrium, and yet able to appropriately capture
the special role of the government.
