4. In the United States, each state governm impose its own excise tax on the sale of cigarettes. Suppose that in the state of North Texarkana, the state government imposes a tax of $2.00 per pack sold within the state. In contrast, the neighboring state of South Texarkana imposes no excise tax on cigarettes. Assume that in both states the pre-tax price of a pack m of cigarettes is $1.00. Assume that the total cost to a resident of North Texarkana to smuggle a pack of ciga- rettes from South Texarkana is $1.85 per pack. (This includes the cost of time, gasoline, and so on.) Assume that the supply curve for cigarettes is neither perfectly elastic nor perfectly inelastic. a. Draw a diagram of the supply and demand curves for cigarettes in North Texarkana showing a situation in which it makes economic sense for a North Tex- arkanan to smuggle a pack of cigarettes from South Texarkana to North Texarkana. Explain your diagram. b. Draw a corresponding diagram showing a situa- tion in which it does not make economic sense for a North Texarkanan to smuggle a pack of cigarettes from South Texarkana to North Texarkana. Explain your diagram. c. Suppose the demand for cigarettes in North Texar- kana is perfectly inelastic. Draw a corresponding diagram to illustrate how high the cost of smug- gling a pack of cigarettes could go until a North Texarkanan no longer found it profitable to smuggle. Explain your diagram. d. Still assume that demand for cigarettes in North Texarkana is perfectly inelastic and that all smokers in North Texarkana are smuggling their cigarettes at a cost of $1.85 per pack, so no tax is paid. Is there any inefficiency in this situation? If so, how much per pack? Suppose chip-embedded cigarette packag ing makes it impossible to smuggle cigarettes across the state border. Is there any inefficiency in this situation? If so, how much per pack? in
