Summary:

According to the World Health Organization, obesity is one of the greatest public-health challenges of the 21st century. Body weight is also known to affect individuals' self-esteem and interpersonal relationships, including romantic ones. We estimate "utility-maximizing" Body Mass Index (BMI) and calculate the implied monetary value of changes in both individual and spousal BMI, using the compensating income variation method and data from the Swiss Household Panel. Two-stage least squares models are estimated for women and men separately, with mother's education as an instrument to account for the potential endogeneity in income. Results suggest that the optimal own BMI is 27.4 and 22.7 for men and women, respectively. The annual value of reaching optimal weight ranges from $3,235 for underweight women to $32,378 for obese women and from $19,088 for underweight men to $43,175 for obese men. Women on average value changes in their own BMI about three times higher than changes in their spouse's BMI. Men, on the other hand, value a reduction in their spouse's BMI almost twice as much compared to a reduction in their own BMI.
