Individual cigarette consumption and addiction: a flexible limited dependent variable approach

Area of Science:

• Econometrics
• Public Health
• Behavioral Economics

Background:

• Limited dependent variable models are common in microeconometric smoking research.
• Previous models often fail to capture the simultaneous nature of smoking decisions.

Purpose of the Study:

• To present a general model for the simultaneous decisions of smoking quantity and quitting.
• To incorporate fixed costs of quitting and separate addiction effects on participation and consumption.
• To improve upon existing microeconometric models of smoking behavior.

Main Methods:

• Developed a general simultaneous equation model for smoking behavior.
• Incorporated fixed costs for quitting decisions.
• Allowed separate modeling of addiction's influence on smoking participation and consumption.
• Applied the model to the 1984-85 UK Health and Lifestyle Survey data.

Main Results:

• The proposed model offers more flexible parameterization and distributional assumptions.
• It effectively captures the interplay between smoking quantity and the decision to quit.
• The model demonstrates superior performance compared to nested models in empirical analysis.

Conclusions:

• The new model provides a more comprehensive framework for analyzing smoking behavior.
• It offers valuable insights into the economic and addictive factors influencing smoking.
• This approach advances microeconometric analysis of health-related behaviors.
