Penalized Convex Estimation in Dynamic Location Models

Journal of Time Series Analysis, EarlyView.
ABSTRACT This paper studies L1$$ {L}^1 $$‐penalized estimation for location models yt=mt+ϵt$$ {y}_t={m}_t+{\epsilon}_t $$, where mt$$ {m}_t $$ is defined by a possibly non‐Markovian recursion and ϵt$$ {\epsilon}_t $$ is a martingale difference sequence with possibly time‐varying conditional variance.

Reinforcement Learning for Jump‐Diffusions, With Financial Applications

Mathematical Finance, EarlyView.
ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

Economic Growth Vulnerability Across Euro Area Countries

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We analyse growth vulnerability in the four largest Euro Area (EA) economies, measured as a lower quantile of the growth distribution conditional on EA‐wide and country‐specific macroeconomic/financial factors. Growth densities are obtained under a normal activity scenario and under stressed conditions.

Weaponizing Kinship: A Demographic Analysis of Bereavement in the Colombian Conflict

Population and Development Review, EarlyView.
Abstract The ongoing Colombian armed conflict has produced widespread homicides and enforced disappearances, as armed actors used violence to terrorize communities and consolidate power. Family bereavement—one of the most pervasive and enduring consequences of this violence—remains critically understudied from a quantitative perspective.

Applied nucleation promotes recovery of New Zealand raised bog vegetation toward a reference community

Restoration Ecology, EarlyView.
Abstract Introduction Applied nucleation aims to restore degraded ecosystems efficiently by establishing vegetation patches that increase in biodiversity and extent through natural dispersal and facilitation. Although widely tested in terrestrial ecosystems, its long‐term outcomes in wetlands remain poorly understood, particularly how restored ...

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.
