Question:

According to the Energy Information Administration, crude oil jointly supplies gasoline, heating oil, jet fuel, lubricating oils, asphalt, and many other products. Suppose the widespread adoption of electric vehicles (EVs) reduces gasoline demand but does not affect the demand for the other products jointly supplied by oil. How will the widespread adoption of EVs affect the prices of these other products?
