Drivers of smoking and physical activity in Russia: Do individual time preferences matter?

Abstract

This article analyzes the relationship between individual decisions to smoke and to do physical exercises. It is assumed that individual time preferences play a major role in explaining individual health behavior. The database is the special survey of Russians’ lifestyle conducted in 2017. A multivariate probit model with endogenous binary variable enables to analyze the relationship between smoking, doing physical exercises, and individual time preferences. Individual time preferences are determined through a hypothetical money experiment. An individual discount rate is used as a proxy for the rate of time preferences. We reveal that there is a negative relationship between smoking and doing physical exercises because of unobservable factors. It might be an individual inclination to follow a healthy or unhealthy lifestyle. There is a negative influence of the higher individual discount rate on doing physical exercises and a positive influence of the higher individual discount rate on smoking. Social policy should accentuate the short-term benefits from smoking cessation and regular physical exercises rather than probable future health improvements. For target groups with the higher individual discount rate, highlighting the short-term negative consequences of avoiding healthy behaviors will be more effective than drawing attention to future health risks.
