The Evolution of Inflation Control: From Fiscal Measures to Monetary Policy
Economist Saul Eslake has outlined the historical progression and the factors contributing to the shift in primary inflation control mechanisms from fiscal measures, such as taxation, to monetary policy, primarily interest rate adjustments. He detailed that while tax increases were a standard response before the late 1970s, subsequent changes in legislative processes and political accountability dynamics led to a preference for central bank-administered interest rate adjustments.

Historical Approaches to Inflation Management
Prior to the late 1970s, increasing taxes served as the standard governmental response to rising inflation. Conversely, tax reductions were employed to address periods of high unemployment.
An example of this approach occurred following the Korean War wool boom, when Australia experienced inflation exceeding 20%. The Menzies government implemented a 10% charge on both company and personal income tax. Additionally, the wholesale sales tax rate was increased from 8.5% to 12.5%. These measures were considered effective in controlling inflation at the time, with the then-treasurer reportedly confirming their efficacy.
Shift to Monetary Policy
The late 1970s marked a significant shift in economic policy, with monetary policy, particularly the adjustment of interest rates, gaining favor among economists. This change was notably influenced by the theories of Milton Friedman.
Factors Contributing to the Policy Shift
Several factors contributed to the increased reliance on interest rate adjustments over taxation for inflation control:
Implementation Speed: Interest rates can be adjusted more rapidly than taxes, which typically require legislative approval. This speed offers a significant advantage in responding to rapidly changing economic conditions.
Legislative Challenges: After the 1970s, governments often lost consistent control of the Senate. This made the passage of new or revised tax legislation considerably more challenging and time-consuming, hindering agile fiscal responses.
Political Accountability: The use of an independent central bank to adjust interest rates allows governments to attribute these decisions to the central bank. This provides a mechanism for politicians to distance themselves from direct responsibility for potentially unpopular decisions that may lead to temporary public economic hardship.
Eslake noted that central banks can serve as a "convenient foil" for politicians in this context, enabling governments to avoid direct responsibility for such measures, even when they are considered to be in the national interest.
