Pension Systems (Un)sustainability and Fiscal Constraints: A Comparative Analysis

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT Using an overlapping generations model, two new indicators of public pension system sustainability are proposed: the pension space, which measures the capacity to pay for pension expenditures out of labour taxation, and the pension space exhaustion probability reflecting demographic uncertainties.

Do State Lotteries Exploit their Lottery Power? Optimal Lotto Pricing With Heterogeneous Players: Evidence from the United Kingdom

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We propose a new model of revenue‐maximising lottery pricing under income‐related heterogeneity and apply it to 13 years of UK National Lottery data. Our pricing rule shows how a state's lottery power is shaped by heterogeneities in lotto demand and the income distribution, and we study its efficiency and distributional implications.

Comparative Analysis of Three Vertebral Screw Placement Directions in Anterior Thoracolumbar Fracture Surgery: A Finite Element Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1464-1477, May 2025.
This study compares the biomechanical effects of three anterior fixation systems in thoracolumbar surgery—HXTL, NHXTL, and Medtronic's CD Horizon ANTERIOR. Finite element analysis evaluates stress and displacement across vertebral bodies and support structures under varying load conditions. Results indicate the HXTL system minimizes nail–rod stress yet

The Diffusion of International Environmental Agreements: The Role of Learning, Competition and Emulation

Regulation &Governance, EarlyView.
ABSTRACT International environmental agreements are key instruments for addressing transboundary environmental problems, but treaty ratification remains uneven and clustered across countries despite the proliferation of multilateral treaties. While existing research has concentrated largely on domestic political‐economic determinants, less is known ...

Redistribution and labor market inclusion

The Scandinavian Journal of Economics, EarlyView.
Abstract This paper incorporates labor market inactivity and long‐term unemployment into the framework of optimal redistributive taxation. We examine how a combination of education policy, public employment programs, unemployment benefits, and optimal income taxation can effectively address both redistributive goals and the persistent challenges of ...
