IB Economics guide, first assessment 2022

Review IB Economics HL taxation calculations through average tax rates, marginal bands, VAT-inclusive prices and additional income tax from data tables.

How this is tested

  • calculate average tax rates by dividing total tax paid by income and converting to a percentage
  • calculate VAT or indirect tax from tax-inclusive expenditure and the tax rate
  • work out additional income tax when a marginal rate or income band changes

"Best Meals" is one of many small catering companies, each of which prepares a variety of different meals for airlines in Country X. Table 1 shows the costs of production in US dollars (US$) on a per hour basis for "Best Meals".

- The aviation sector creates emissions that account for about 4.9 % of human made global warming and its share of greenhouse gas emissions is rapidly growing.
- A flight from San Francisco to Paris can produce around 1.25 metric tons of carbon emissions per passenger. This is more CO2\mathrm{CO}_{2} than the average person in certain countries generates in an entire year.
- The energy source for aircraft is not easily substitutable. Road and rail-based passenger vehicles can switch from carbon-based fuels to renewably sourced electricity. Aviation emissions are thus not expected to be easily reduced.
- The aviation industry's growth has also accelerated as a result of subsidies, including general sales tax and fuel tax exemptions, which are unavailable to other modes of transport.
