Estimating cross-price elasticity of e-cigarettes using a simulated demand procedure

Area of Science:

• Tobacco Control Research
• Consumer Behavior Analysis
• Public Health Policy

Background:

• Understanding the relationship between electronic cigarettes (e-cigarettes) and traditional tobacco products is crucial for public health.
• Assessing the substitutability and impact of e-cigarettes on tobacco consumption is a key area of research.

Purpose of the Study:

• To measure the cross-price elasticity between e-cigarettes and tobacco cigarettes.
• To simulate the effect of e-cigarette availability on tobacco cigarette demand.
• To evaluate how e-cigarette availability influences smokers' decisions to quit at varying price points.

Main Methods:

• A Cigarette Purchase Task was administered to 210 New Zealand smokers.
• Participants rated the favorability of e-cigarettes and their own-brand tobacco.
• Simulated purchase quantities of e-cigarettes and tobacco cigarettes were recorded at different price levels (0.5x, 1x, 2x market price).

Main Results:

• E-cigarettes demonstrated a positive cross-price elasticity (0.16) with tobacco cigarettes, indicating partial substitutability.
• The availability of e-cigarettes led to a 42.8% decrease in simulated demand for tobacco cigarettes at current prices.
• At double the current cigarette price, significantly more smokers intended to quit if e-cigarettes were unavailable (50.2%) versus available (30.0%).

Conclusions:

• E-cigarettes are a potential substitute for tobacco cigarettes, capable of reducing overall tobacco consumption.
• The availability of e-cigarettes may reduce the incentive for some smokers to quit entirely, particularly as tobacco prices increase.
• Policymakers should consider maintaining a consistent price difference between e-cigarettes and tobacco cigarettes to optimize public health outcomes.
