This paper develops and implements a GMM estimator for latent class models suitable for count data. The estimator uses conditional moment restrictions derived from standard count models. Both the efficient and consistent variants are considered. The implementation of optimal GMM based on...

This study uses county-level variation in implementation of calorie labeling laws in the US to identify the effects of such laws on body mass. Using the 2003 to 2012 waves of the Behavioral Risk Factor Surveillance System, we find a statistically insignificant average treatment effect for women...

We construct a joint distribution of fertility and children's activities treating the Poisson process generating the number of children as being endogenous in the multinomial logit process generating children's activities using a latent factor structure. Latent factors are incorporated into the...
