1. There is debate around the causes of current high inflation, with some arguing it is due to excess aggregate demand from fiscal stimulus while others point to supply-side factors like the pandemic, war in Ukraine, and labor force participation decline. 2. To reduce inflation, the Fed has raised interest rates rapidly since mid-2022, hoping for a soft landing, while others argue larger unemployment increases are needed. However, raising rates may not address supply problems and could lead to recession. 3. Alternative approaches to raising rates include price controls, social coordination of prices and wages, and addressing inequality, as inflation impacts lower-income households more. Underlying causes of inflation involve distribution and power dynamics between economic classes.
