Understanding UK Productivity Using a Macroeconomic Lens

open access: yesJournal of Economic Surveys, Volume 40, Issue 1, Page 214-241, February 2026.
ABSTRACT We survey UK labor productivity over the long run, comparing it with other advanced economies, and focus on the sharp slowdown since the global financial crisis. Using a growth accounting framework, we highlight the primary role of total factor productivity (TFP), while noting that the contribution of capital shallowing is influenced by ...

Pólya's conjecture for Dirichlet eigenvalues of annuli

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract We prove Pólya's conjecture for the eigenvalues of the Dirichlet Laplacian on annular domains. Our approach builds upon and extends the methods we previously developed for disks and balls. It combines variational bounds, estimates of Bessel phase functions, refined lattice point counting techniques and a rigorous computer‐assisted analysis. As

Fast change point analysis on the Hurst index of piecewise fractional Brownian motion [PDF]

open access: yes, 2011
In this presentation, we introduce a new method for change point analysis on the Hurst index for a piecewise fractional Brownian motion. We first set the model and the statistical problem.

Tree-based conditional copula estimation

open access: yesDependence Modeling
This article proposes a regression tree procedure to estimate conditional copulas. The associated algorithm determines classes of observations based on covariate values and fits a simple parametric copula model on each class.
