Monetary policies in the 1980s failed due to successful application.
The relationship between money growth and the economy changed in the 1980s, with money no longer directly impacting economic activity. However, recent research suggests that traditional monetary relationships still hold true. The apparent failure of monetarism in the 1980s was actually due to successful application. Federal Reserve policies have become more effective and less influenced by economic cycles. As a result, there is little correlation between money growth and non-financial economic activity.
