Global Representation of the Conditional LATE Model: A Separability Result*

Yu‐Chang Chen, Haitian Xie

Oxford Bulletin of Economics and Statistics > 84 > 4 > 789 - 798

This paper studies the latent index representation of the conditional LATE model, making explicit the role of covariates in treatment selection. We find that if the directions of the monotonicity condition are the same across all values of the conditioning covariate, which is often assumed in the literature, then the treatment choice equation has to satisfy a separability condition between the instrument...

Nano Research > 2019 > 12 > 6 > 1293-1300

DNA is a self-assembled, double stranded natural molecule that can chelate and align nickel ions between its base pairs. The fabrication of a DNA-guided nickel ion chain (Ni-DNA) device was successful, as indicated by the conducting currents exhibiting a Ni ion redox reaction-driven negative differential resistance effect, a property unique to mem-elements (1). The redox state of nickel ions in the...
