The article explores whether inflation targeting works with Post Keynesian economics by looking at how manipulating interest rates can affect inflation. The researchers use a model that considers the cost channel of monetary policy, which is often overlooked in mainstream economics. They find that the type of Phillips curve used in the model has a bigger impact on macroeconomic stability than the cost channel itself. This suggests that traditional policy approaches may not be the best for stabilizing the economy in a monetary-production system.
