The Monetary Policy–Commodities Nexus: A Survey
Journal of Economic Surveys, Volume 40, Issue 2, Page 1050-1082, April 2026.ABSTRACT This survey synthesizes evidence on the bidirectional links between commodity markets and monetary policy. On the commodities‐to‐policy side, we review how shocks to energy, food, and metals pass through to inflation, inflation expectations, economic activity, and financial stability in state‐dependent ways that vary by shock type, exposure ...

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.Abstract Many atmospheric chemical processes, including the formation of secondary organic aerosol (SOA), are strongly modulated by the reactions of NO and NO2NOx ${\text{NO}}_{2}\ \left({\text{NO}}_{x}\right)$. Though NOx ${\text{NO}}_{x}$ is controlled by anthropogenic emissions near urban areas, in rural areas soil microbes can be a significant ...

The topology of Rayleigh-Levy flights in two dimensions
Astronomy & AstrophysicsRayleigh-Lévy flights are simplified cosmological tools that capture certain essential statistical properties of the cosmic density field, including hierarchical structures in higher-order correlations, making them a valuable reference for studying the highly non-linear regime of structure formation.

Levy flight is not evolved behavior
, 2011 Tracks of moving animals have many short moves interspersed with longer moves, and frequencies of all moves together often indicate Levy flights (a type of power law)1. The Levy flight foraging hypothesis suggests that, ‘since Levy flights and walks can optimize search efficiencies, therefore natural selection should have led to adaptations for Levy ...
