Confidence Intervals for Price Discovery
Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 742-764, August 2026.ABSTRACT This paper discusses asymptotic and bootstrap confidence intervals for multivariate permanent‐transitory decompositions of cointegrated vector autoregressive I(1) systems, with a focus on price discovery. Alternative estimators of the permanent components are compared in terms of efficiency also under separable linear restrictions on the ...

Inference on Common Trends in a Cointegrated Nonlinear SVAR
Oxford Bulletin of Economics and Statistics, Volume 88, Issue 4, Page 658-676, August 2026.ABSTRACT We consider the problem of performing inference on the number of common stochastic trends when data is generated by a cointegrated CKSVAR (a two‐regime, piecewise affine SVAR; Mavroeidis, 2021), using a modified version of the Breitung (2002) multivariate variance ratio test that is robust to the presence of nonlinear cointegration (of a known

A Matrix‐Free, Scalable, and Robust Implicit Material Point Method
International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.ABSTRACT An implicit material point method is presented using a new dynamic relaxation solver, allowing for a simple and efficient quasi‐static formulation that may be readily implemented in existing explicit‐dynamic codes. The use of dynamic relaxation and aggregation is shown to produce an extremely robust material point method scheme, with good ...

International Journal for Numerical Methods in Engineering, Volume 127, Issue 14, 30 July 2026.ABSTRACT Numerical anisotropy and dispersion are inherent consequences of spatial discretization in finite element modeling of wave propagation. In two‐dimensional problems, these effects manifest not only as direction‐dependent phase and group velocities but also as angularly dependent numerical band gaps that may entirely suppress wave propagation ...

Bernstein operators in Chebyshev spaces [PDF]
, 2008 International audienceWe explain why, on a given interval $[a,b]$, each Extended Chebyshev space possesses infinitely many Bernstein type operators, and we analyse how to build such operators.

On variants of Chebyshev’s conjecture
The Ramanujan JournalAbstract We show that the sign constancy for the values of certain weighted summatory functions of the von Mangoldt function implies Riemann Hypothesis or Generalized Riemann Hypothesis for Dirichlet L -functions.
