%0 Report %A Gross, Isaac %A Leigh, Andrew %T Assessing Australian Monetary Policy in the Twenty-First Century %D 2022 %8 2022 Sep %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 15561 %U https://www.iza.org/publications/dp15561 %X Using the Reserve Bank of Australia's MARTIN model we compare actual monetary policy decisions to a counterfactual in which the cash rate is set according to an optimal simple rule. We find that monetary policy played a crucial role in avoiding a potential recession in 2001 and mitigating the downturn in 2008-2009. By contrast we find that the cash rate was too high during 2016-2019, keeping inflation below the Reserve Bank's target band. Optimal monetary policy in 2016-2019 would have involved a substantially lower cash rate and would have produced significantly better employment outcomes. %K unemployment %K optimal monetary policy %K output gap %K inflation
