Question 41 pts

The estimated price elasticity of demand for cigarettes is -0.4 in high-income countries and -0.8 in lower-income countries. If a country’s government raises taxes on cigarettes, the price to consumers goes up. The extra revenue collected from the higher price goes to the government.

Would imposing a new tax on cigarettes stop more people from smoking in a high or lower-income country?

The tax would not reduce smoking in either country.
