Do robots boost productivity? A quantitative meta‐study

Journal of Economic Surveys, Volume 40, Issue 3, Page 1531-1571, July 2026.
ABSTRACT This meta‐study analyzes the productivity effects of industrial robots. More than 1800 estimates from 85 primary studies are collected. The meta‐analytic evidence suggests that robotization has so far provided, at best, a small boost to productivity. There is strong evidence of publication bias in the positive direction.

Econometrics at the Extreme: From Quantile Regression to QFAVAR1

Journal of Economic Surveys, Volume 40, Issue 3, Page 1672-1686, July 2026.
ABSTRACT This paper surveys quantile modelling from its theoretical origins to current advances. We organize the literature and present core econometric formulations and estimation methods for: (i) cross‐sectional quantile regression; (ii) quantile time series models and their time series properties; (iii) quantile vector autoregressions for ...

Leafcutter Ant Farmers Prevent Loss of Edible Symbiotic Structures by Maintaining Allelic Diversity in Their Multinucleate Fungal Crop

Molecular Ecology, Volume 35, Issue 13, July 2026.
ABSTRACT Leafcutter ants farm the domesticated fungal cultivar Leucoagaricus gongylophorus in subterranean nests containing up to hundreds of discrete garden chambers. The fungal cultivar produces edible symbiotic structures called gongylidia (nutritious swollen hyphal cells consumed by the ants) and expresses a form of polyploidy (multiple ...

Pseudomonas volatiles shape the root transcriptome and microbiome to promote plant growth under drought

New Phytologist, Volume 251, Issue 1, Page 405-423, July 2026.
Summary Volatile organic compounds (VOCs) emitted by soil bacteria influence interactions with other soil microbes and plants. While their potential as plant growth promoters is well recognized, their role in promoting plant resilience to abiotic stress and the underlying molecular mechanisms remain poorly understood.

Competition and Collaboration in the AI Race: Country‐Level Directional Evidence for Risk Monitoring and Policy

Risk Analysis, Volume 46, Issue 7, July 2026.
ABSTRACT Artificial intelligence (AI) is reshaping national economies, yet country‐level AI–macro relationships remain poorly understood. Using annual data for the United States and China, 1980–2020, we develop a four‐layer triangulation framework—Pattern Causality, Granger causality, VECM‐based cointegration, and lead–lag correlation—to map ...
