Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT In VECMs (or CVARs), the weak exogeneity of some of the variables (for the long‐run parameters) is related to the equilibrium adjustment dynamics. This has sometimes led to the statistical concept of weak exogeneity being given a causal interpretation.

Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT A popular approach to interactive effects panel data models is the common correlated effects (CCE) estimator of Pesaran (Estimation and inference in large heterogeneous panels with a multifactor error structure. Econometrica 74, 967–1012, 2006). The current paper proposes a modified version of this estimator that is useful in a number of cases

Trade Reform in Services: Structural Change and Production Networks
Review of International Economics, EarlyView.ABSTRACT We study the effects of services trade reforms in a multi‐country multi‐sector quantitative trade model with input–output linkages. Services matter both as final consumption and as production inputs: cheaper traded services lower household prices directly and reduce the costs of downstream producers also indirectly.

Rational points on even‐dimensional Fermat cubics
Transactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.Abstract We show that even‐dimensional Fermat cubic hypersurfaces are rational over any field of characteristic not equal to three, by constructing explicit rational parameterizations with polynomials of low degree. As a byproduct of our rationality constructions, we obtain estimates for the number of their rational points over a number field and ...

The mod 2 Seiberg–Witten invariants of spin structures and spin families
Journal of Topology, Volume 19, Issue 4, December 2026.Abstract We completely determine the mod 2 Seiberg–Witten invariants for any spin structure on any closed, oriented, smooth 4‐manifold X$X$. Our computation confirms the validity of the simple‐type conjecture mod 2 for spin structures. Our proof also works for families of spin 4‐manifolds and thus computes the mod 2 Seiberg–Witten invariants for spin ...

The Legendrian Hopf link has exactly two Lagrangian fillings
Journal of Topology, Volume 19, Issue 4, December 2026.Abstract We prove that there are precisely two embedded exact Lagrangian fillings of the standard Legendrian Hopf link, up to compactly supported Hamiltonian isotopy. It was known that the standard Legendrian Hopf link admitted at least two such Lagrangian fillings: we show these are all.

British Journal of Mathematical and Statistical Psychology, Volume 79, Issue 3, Page 590-620, November 2026.Abstract Reliability evaluation is critical in fields such as psychology and medicine to ensure accurate diagnosis and effective treatment management. When participants are evaluated by the same raters, a two‐way ANOVA model is suitable to model the data, with the intraclass correlation coefficient (ICC) serving as the reliability metric.
