We study the informational content of factor structures in discrete triangular systems. Factor structures have been employed in a variety of settings in cross sectional and panel data models, and in this paper we formally quantify their identifying power in a bivariate system often employed in...

The basic objective of this investigation is to explore the impactof a novel gravitational modification, specifically, the$f(\mathcal{G}, \mathbf{T}^2)$ (where $\mathcal{G}:=\mathbf{R}^{2}+R_{\alpha\beta\sigma\varsigma}R^{\alpha\beta\sigma\varsigma}-4R_{\alpha\beta}R^{\alpha\beta}$and...

"This paper considers nonparametric identification and estimation of a generalized Roy model that includes a non-pecuniary component of utility associated with each choice alternative. Previous work has found that, without parametric restrictions or the availability of covariates, all of the...
