Random Carbon Tax Policy and Investment Into Emission Abatement Technologies
Mathematical Finance, EarlyView.ABSTRACT We analyze the problem of a profit‐maximizing electricity producer, subject to carbon taxes, who decides on investments into CO2$\rm CO_2$ abatement technologies. We assume that the carbon tax policy is random and that the investment in the abatement technology is divisible, irreversible, and subject to transaction costs.

Relative Arbitrage Opportunities With Interactions Among N Investors
Mathematical Finance, EarlyView.ABSTRACT The relative arbitrage portfolio outperforms a benchmark portfolio over a given time‐horizon with probability one. With market price of risk processes depending on the market portfolio and investors, this paper analyzes the multi‐agent optimization of relative arbitrage opportunities in the coupled system of market and wealth dynamics.

Stochastic Simulation Model for Forecasting Index‐Linked Public Expenditure
Public Budgeting &Finance, EarlyView.Abstract This paper introduces a system dynamics (SD) model for analyzing public sector cost growth, where costs are tied to indices. The SD model isolates the effects of automatic indexation, providing probabilistic projections of expenditure growth. It enables testing of alternative indexation strategies and cost‐reduction measures. Findings show how

Regulation &Governance, EarlyView.ABSTRACT This study investigates how bureaucratic strategies for structuring the policy environment shape regulatory outcomes, focusing on the extent to which agencies achieve their original policy preferences. Drawing on resource dependence theory and bureaucratic politics, we conceptualize the policy environment in two dimensions: internal ...

Likelihood Estimation for Stochastic Differential Equations with Mixed Effects
Scandinavian Journal of Statistics, EarlyView.ABSTRACT Stochastic differential equations provide a powerful tool for modelling dynamic phenomena affected by random noise. When time series are observed for several experimental units, it is often the case that some of the parameters vary between the individual experimental units.

Legume Science, Volume 8, Issue 2, June 2026.ABSTRACT Instrumental characterisation of the volatile organic compounds (VOCs), responsible for off‐aroma, is mainly centred on gas chromatography‐based techniques. Despite previous reviews that have addressed the chemical compounds and biosynthetic pathways of off‐aroma generation, to date, there is a lack of a comprehensive review that critically ...

Journal of Contingencies and Crisis Management, Volume 34, Issue 2, June 2026.ABSTRACT This study examined the developmental processes of paracrises and reputational threats amplified on social media, through a case study of the Adidas SL72 sneaker campaign, a faux pas‐type paracrisis. Unlike crises that directly threaten organizational survival, paracrises are reputational threats that primarily impact corporate social ...

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.Abstract A small phreatic eruption occurred on April 2018 Iwo‐yama, Kirishima volcanic complex, Japan. We estimated the change in the subsurface resistivity structure before and after the phreatic eruption by repeated magnetotelluric (MT) measurements. A substantial decrease in resistivity was determined in the zone from the surface down to a depth of ...
