A petroleum refinery operating in Rivers State processes crude oil through fractional distillation, resulting in the simultaneous production of premium motor spirit (petrol) and bitumen from the same refining process. An increase in the output of petrol automatically leads to an increase in the output of bitumen. Which type of supply is demonstrated in this scenario?
- Joint supplyCevap
- BCompetitive supply
- CComposite supply
- DDerived supply
Cevap
Joint supply
Joint supply (also known as complementary supply) occurs when two or more goods are produced simultaneously from the same raw material or production process. Because petrol and bitumen are co-products of refining crude oil, an increase in petrol production inherently expands the supply of bitumen.
