High‐Frequency Instruments With Time‐Varying Reliability: Understanding Identification in Macroeconomics

Journal of Applied Econometrics, EarlyView.
ABSTRACT The effects of monetary policy shocks are regularly estimated using high‐frequency surprises in asset prices around central bank meetings as an instrument. These studies, insofar as they explicitly model the relationship between instrument and structural shock, assume a constant relationship between the instrument and the monetary policy shock.

Toward an idiographic understanding of the role of sleep‐mood dynamics in adolescents' internalizing symptoms

JCPP Advances, EarlyView.
Abstract Background Adolescence is marked by increased vulnerability to sleep disturbances and mood disorders. Understanding how day‐to‐day changes in sleep and mood are linked within the same individual is crucial for clarifying sleep's role in emerging internalizing disorders. However, the extent to which an adolescent's fluctuations in sleep predict

Hitting Times in the Binomial Random Graph

Journal of Graph Theory, EarlyView.
ABSTRACT Fix k ≥ 2 $k\ge 2$, choose log n n ( k − 1 ) ∕ k ≤ p ≤ 1 − Ω ( log 4 n n ) $\frac{\mathrm{log}n}{{n}^{(k-1)\unicode{x02215}k}}\le p\le 1-{\rm{\Omega }}(\frac{{\mathrm{log}}^{4}n}{n})$, and consider G ~ G ( n , p ) $G\unicode{x0007E}G(n,p)$. For any pair of vertices v , w ∈ V ( G ) $v,w\in V(G)$, we give a simple and precise formula for the ...

Non‐Stationary Dry‐Spell Hazard Probabilities for Spain

International Journal of Climatology, EarlyView.
This study assesses long‐term changes in dry‐spell hazard probabilities across Spain (1961–2024) using a novel non‐stationary extreme value framework applied to daily precipitation records from a dense observational network. Results show that dry‐spell duration and associated return levels are dominantly stationary, with non‐stationary models providing
