Left-Digit price effects on smoking cessation motivation

Abstract

Results: As price increases, probability of making a smoking cessation attempt exhibited an orderly increase, with the form of the relationship being similar to an nverted demand curve. The largest effect size increases in motivation to make a quit attempt were in the form of left-digit effects,’ (ie, maximal sensitivity across pack price whole-number changes; eg, US$5.80–6/pack). Significant differences were also observed among the left-digit effects, suggesting the most substantial effects were for price changes that were most market relevant. Severity of nicotine dependence was significantly associated with price sensitivity, but not for all indices.
