In this paper we investigate obese/non-obese wage differentials using microdata for white individuals from the 2000 wave of the National Longitudinal Survey of Youth. Using longitudinal information we estimated transition probability indices and synthetic mobility measures for moving in-and-out of the obese group. The results clearly show that obesity is a rather permanent characteristic. Then, we apply typical Oaxaca-Blinder wage decompositions to identify the proportion of the observed gender-specific wage differential between obese and non-obese. Based on numerous specifications and alternative sub-samples the results provide strong evidence for the existence of wage differentials in favor of non-obese individuals, which can be mostly explained by differences in early human capital investments and especially schooling investments.

This study investigates dynamic patterns of obesity persistence and identifies the determinants of obesity-spell exits and re-entries. We utilize longitudinal data from the NLSY79 covering the period 1985-2010. Non-parametric techniques are applied to investigate the relationship between exit from obesity and spell duration. Multivariate discrete hazard models are also estimated, taking into account duration dependence and observed and time-invariant unobserved heterogeneity. In all cases, the probability of exiting obesity is inversely related to the duration of the obesity spell. Without controlling for unobserved heterogeneity, the probability of exit after one wave in obesity is 31.5 per cent; it is reduced to 3.8 per cent after seven or more waves. When time-invariant unobserved heterogeneity is taken into account, the estimated probabilities are slightly larger and broadly similar (36.8 and 10.3, respectively), which suggests that the identified negative duration dependence is not primarily due to composition effects. The obtained results indicate that public health interventions targeting the newly obese may be particularly effective at reducing incidence of long durations of obesity.
