Riverine Biogeochemical Exports From Major Watersheds to the Northwest Patagonian Estuarine Network

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract River discharge considerably influences marine ecosystems through hydrological and biogeochemical drivers. Measuring baseline variability of riverine inputs, and their relation to anthropogenic land‐use impacts and global climate stressors affecting watersheds is therefore crucial for managing coastal marine ecosystems.

Large‐Dimensional Cointegrated Threshold Factor Models: The Global Term Structure of Interest Rates

open access: yesOxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 677-689, August 2026.
ABSTRACT In this paper we extend the two‐level factor model to account for cointegration between group‐specific factors in large datasets. We propose two nonlinear specifications: (i) a threshold vector error correction model (VECM) that allows for asymmetric adjustment across regimes; and (ii) a band VECM that captures state‐dependent adjustment which
