The Surprising Bias of PPML Estimates of Structural Gravity Models With Two‐Way Fixed Effects

open access: yesReview of International Economics, EarlyView.
ABSTRACT The previous literature has shown that the Poisson Pseudo‐Maximum Likelihood (PPML) estimator provides consistent and asymptotically unbiased estimates of the parameters of structural gravity models with two‐way fixed effects, although their standard errors need correction.

Geopolitical Risk and Military Spending: Reassessing Specification and Measurement

open access: yesScottish Journal of Political Economy, EarlyView.
ABSTRACT Tran and Vo analysed English‐language‐based geopolitical risk (GPR) indices and argued that local GPR dominates global GPR in explaining military spending worldwide. We revisit this claim by addressing limitations in their empirical design and measurement.

An experimentally informed computational model of neurovestibular adaptation to altered gravity

open access: yesExperimental Physiology, EarlyView.
Abstract Transitions to altered gravity environments result in acute sensorimotor impairment for astronauts, leading to serious mission and safety risks in the crucial first moments in a new setting. Our understanding of the time course and severity of impairment in the early stages of adaptation remains limited and confounded by unmonitored head ...

A JACKKNIFE VARIANCE ESTIMATOR UNDER TWO-FASES SAMPLING WITH UNEQUAL PROBABILITY UN ESTIMADOR JACKKNIFE DE VARIANZA EN MUESTREO EN DOS FASES CON PROBABILIDADES DESIGUALES

open access: yesRevista Colombiana de Estadística, 2007
We propose a jackknife variance estimator under two-fases sampling with unequal probability. We assume that the parameters of interest and its stimators can be expressed as a function of means.

Calibration of Retrospective and Prospective Life Satisfaction Judgments Around the World

open access: yesFUTURES &FORESIGHT SCIENCE, Volume 8, Issue 2, August 2026.
ABSTRACT It is both a physical and psychological fact that humans have access to records of the past but not to records of the future. Due to this epistemic asymmetry in time, we hypothesized that retrospection about past psychological states will be better calibrated than prospection about future psychological states.

Un estimador jackknife de varianza en muestreo en dos fases con probabilidades desiguales A Jackknife Variance Estimator under Two-Fases Sampling with Unequal Probability

open access: yesRevista Colombiana de Estadística, 2007
Se emplea la metodología jackknife para muestreo con probabilidades desiguales en la estimación de varianza de estimadores basados en diseños de muestreo en dos fases con probabilidades desiguales.

Paleosecular Variation Constraints on Geomagnetic Field Morphology at ca. 1100 Ma

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Paleosecular variation provides a statistical test of long‐term geomagnetic field morphology, but its behavior across Precambrian polarity regimes remains poorly constrained. We compile a virtual geomagnetic pole dispersion data set spanning 1130–1070 Ma and apply nonlinear Model G fitting to evaluate field structure across the interval ...

Tax Policy and Farm Organization

open access: yesApplied Economic Perspectives and Policy, Volume 48, Issue 3, Page 780-796, July 2026.
ABSTRACT The Tax Cuts and Jobs Act (TCJA) introduced substantial changes to the tax code, affecting farms' organizational incentives. This study examines farms' responses to the TCJA along extensive and intensive margins, focusing on organizational and labor expense adjustments.
