|December 2016||Who Benefits Most from SNAP? A Study of Food Security and Food Spending|
with Partha Deb: w22977
We study the effects of SNAP participation on food insecurity and food spending using finite mixture models that allow for a priori unspecified heterogeneous effects. We identify a low food security subgroup comprising a third of the population for whom SNAP participation increases the probability of high food security by 20-30 percentage points. There is no affect of SNAP on the remaining two-thirds of the population. SNAP increases food spending in the previous week by $50-$65 for a low modal spending subgroup comprising two-thirds of the population, with no effect for the remaining third of the population.

The literature examining the relationship between body mass index (BMI) and wages has fairly consistently found that BMI has a negative impact on earnings for women, and less (if any) consequences for men. In this paper, we relax the assumption -- largely unquestioned in this research -- that the conditional mean of wages is linear or piecewise linear in body mass index (BMI). Using data from the 1986 and 1999-2005 Panel Study of Income Dynamics, we estimate semi-parametric wage models that allow earnings to vary with BMI in a highly flexible manner. For women, the results show that earnings peak at levels far below the clinical threshold of "obesity" or even "overweight". For men, our main estimates suggest a reasonably flat BMI-wage profile that peaks early in the "overweight" category. ...
