The Great British Productivity Puzzle and Regional Industries: A Dynamic Multilevel Spatial Frontier Analysis

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT Using two approaches, we contribute to sub‐national economic performance measurement by netting out the influence of a region's performance on its industries. The first approach measures performance using technical efficiency and involves introducing the first multilevel spatial stochastic frontier model.

Penalized Convex Estimation in Dynamic Location Models

open access: yesJournal 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.

Parametric Time‐Variation in the Unconditional Volatility: Estimation and Inference

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT We propose modeling time‐variation in the unconditional volatility by augmenting the standard GARCH model by a deterministic time‐varying intercept. The model, called the additive time‐varying (ATV‐)GARCH model, can be interpreted as a reduced form of a model including covariates and can be derived from a multiplicative decomposition of ...

Seeing the Speaker's Face Enhances Second Language Shadowing: Neural and Behavioral Evidence

open access: yesLanguage Learning, EarlyView.
Abstract This functional magnetic resonance imaging (fMRI) study investigated how facial cues influence second language (L2) shadowing among 42 Japanese learners of English. Participants completed four conditions that varied by task type (listening vs. shadowing) and visual input (face vs. mosaic).
