When wealth or income rises suddenly, the propensity for that "easy money" to be directed towards unproductive use, "easy spending", may rise. The cross-country relationship between conspicuous consumption and revenue windfalls is explored by estimating the response of demand for imports of...

This study leverages the Log-Periodic Power Law Singularity (LPPLS) confidence indicator to effectively identify bubbles in agricultural commodity markets. We analyze five major grain price indices reported by the International Grains Council (IGC) from January 2000 to April 2023, successfully...

The traceability of critical raw materials along the supply chain is pivotal in meeting wider public demands for corporate sustainability and complying with relevant regulations from the European Union that contain requirements for responsible sourcing and the transparency of supply chains. This...

We develop an indirect inference approach relying on a linear supply and demand model serving as an auxiliary model to provide the first full empirical test of the rational expectations commodity storage model. We build a rich storage model that incorporates a supply response and four structural...

Cobalt (Co) is an essential metal used in renewable energy technologies, electro-mobility, aerospace and defence, due to its high-temperature stability and magnetic properties. It plays a crucial role in improving energy density in lithium-ion batteries for electric vehicles and grid storage....

Copper (Cu) is used in all electrical and electronic applications, including renewable energy technologies, power grids, electric vehicles, electronic devices, aircrafts and defence technologies. Copper is mined both underground and open-pit and is widely recycled.

Gallium's (Ga) unique semiconducting properties enable highly efficient power management chips. Gallium arsenide is used for power amplifiers in devices, in telecommunications such as 5G, satellite communication and radar systems. Gallium is also used in thin-film solar panels and LEDs. Gallium...
