Episode notes
Three-Tier GST Simplification
- The GST has been simplified from four main slabs to mainly 5%, 18% and a 40% sin/luxury rate with some special rates remaining.
- Many items moved from 28% to 18%, some from 18% to 5%, and several food items were exempted.
Tax Cuts Fuel Demand But Depend On Context
- Lower GST rates boost consumer purchasing power and raise demand, increasing producer and consumer surplus in the short run.
- Subsequent income gains (wages, profits) can further amplify economic growth but depend on many external factors.
Fuel Prices Can Offset GST Gains
- Petrol and diesel remain outside GST, so international crude prices and exchange rates can offset GST benefits through higher fuel costs.
- External sector dynamics thus influence the real consumer gains from GST rationalization.
