Big Five Personality Traits and Trajectories of Fertility Expectations Across the Reproductive Age Period

open access: yesJournal of Personality, EarlyView.
ABSTRACT Objective In recent decades, increased freedom of choice and advancements in fertility regulation have allowed individuals to follow different fertility paths. This greater autonomy provides room for personality traits to shape long‐term fertility expectations, which in turn can be predictive of fertility outcomes.

Adaptive Estimation for Weakly Dependent Functional Times Series

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We propose adaptive mean and autocovariance function estimators for stationary functional time series under 𝕃p−m‐approximability assumptions. These estimators are designed to adapt to the regularity of the curves and to accommodate both sparse and dense data designs.

Functional Data Analysis of Particulate Matter (PM10) in Chungbuk, Korea: An Application of Penalized B-Spline Smoothing and Functional Inference

open access: yesAxioms
Functional data analysis (FDA) provides a framework for representing high-frequency or longitudinal observations as smooth functions, enabling principled dimension reduction and feature extraction.

Robust Estimation and Inference for Time‐Varying Unconditional Volatility

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We derive a general and robust estimator of a large class of parametric specifications of time‐varying unconditional volatility of financial returns, both univariate and multivariate, and establish the Consistency and Asymptotic Normality (CAN) of the estimator.

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

open access: yesPopulation 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.

Explaining Burden Reduction in Municipal Service Delivery: The Case of Streamlined Electric Vehicle Charger Permitting in California

open access: yesPublic Administration Review, EarlyView.
ABSTRACT Administrative burdens are deliberate policy choices, as governments can proactively design rules and procedures to shape burdens experienced by citizens. While existing research has examined the effects of burden reduction strategies, less is known about the factors driving burden reduction actions at the local level.

Bayesian Inference for Multivariate Monotone Densities

open access: yesScandinavian Journal of Statistics, EarlyView.
ABSTRACT We consider a nonparametric Bayesian approach to estimation and testing for a multivariate monotone density. Instead of following the conventional Bayesian approach of imposing a prior that satisfies the monotonicity restriction, we place a prior on the step heights via binning and a Dirichlet distribution. The resulting posterior distribution
