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...

We use an econometric model of fertility and children’s activities to examine the causal effects of fertility on a child’s activities taking the endogeneity of fertility into account. Our specification is nonlinear and simultaneous and uses latent factors to allow for unobserved influences...

We develop a random effects multinomial logit model to distinguish between unobserved and observed household characteristics as determinants of child labor and school attendance. Using a semi-parametric approach, the random effect is drawn from a discrete distribution of latent classes of...

The minimum density power divergence (MDPD) framework (Basu et al., 1998) provides a family of estimators indexed by a parameter (α), which controls the tradeoff between efficiency and robustness. In this paper, we extend this estimation framework to finite mixtures of regression models. In...

In this article, we describe twopm, a command for fitting two-part models for mixed discrete-continuous outcomes. In the two-part model, a binary choice model is fit for the probability of observing a positive-versus-zero outcome. Then, conditional on a positive outcome, an appropriate...

This paper provides an empirical reconsideration of evidence for excess co-movement of commodity prices within the framework of univariate and multivariate GARCH(1,1) models. Alternative formulations of zero excess co-movement are provided, and corresponding score and likelihood ratio tests are...
