Empirical analysis on the illicit trade of cigarettes in Vietnam.

Vietnam's low prices on domestic cigarettes created favourable conditions for cigarette smugglers and provided easy access to illicit cigarettes for the Vietnamese people, but the absence of a relationship between tax changes and smuggling suggested that potential increases in the excise tax should not be discouraged by the threat of an increase in illicit trade. The government should increase taxes on cigarettes to raise domestic cigarette prices and take strong policy measures to create a more transparent social environment, therefore effectively reducing the prevalence of illicit cigarettes in Vietnam.
