A Comparative Note on the Reliability of Inequality Indicator Estimates

International Statistical Review, EarlyView.
Summary The importance of accurate measurement of economic or social inequality is generally accepted. Estimators of its most popular measure, the Gini coefficient, are commonly criticised for becoming increasingly imprecise for increasingly skewed distributions and small to moderate samples, i.e., two phenomena that we face more frequently today.

A double‐blind randomized controlled trial of personalized upper‐alpha neurofeedback in children with ADHD

Journal of Child Psychology and Psychiatry, EarlyView.
Background Neurofeedback (NF) is a nonpharmacological approach for ADHD, but standard protocols often overlook individual EEG variability, potentially limiting efficacy. We report the first double‐blind randomized controlled trial of a session‐adaptive individualized upper‐alpha NF protocol in children with ADHD, based on individualized 1/f + alpha ...

Unequal and Unstable: Income Inequality and Bank Risk

Journal of Money, Credit and Banking, EarlyView.
Abstract We present a model in which income inequality interacts with banks' risk‐taking incentives, generating financial instability. Competition and deposit insurance cause some banks to lend to lower‐income borrowers at underpriced rates, creating “risky banks” that fail in downturns, while others lend to higher‐income borrowers and avoid default ...
