The article explores how inflation can help stabilize the economy when prices are sticky. The researchers found that in a model with sticky prices, optimal policy leads to less inflation volatility but more tax rate fluctuations. When government spending patterns resemble post-war periods, sticky prices result in stable inflation and random walk-like behavior in tax rates and government debt. However, during times of war and peace, inflation volatility increases significantly, emphasizing the importance of using inflation to absorb economic shocks.
