This paper analyzes the effect of commodity price fluctuations on a commodity-exporting economy. Using Chilean and international copper market data, I find that positive copper price changes resulting from copper-specific demand shocks generate a broad GDP expansion, with no visible decline in...

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....

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...

Boron (B) is used in permanent neodymium magnets, in high-performance glass for e.g. photovoltaic panels, and chip production. Boron fibres and composites are used in aerospace structures, armour and ballistic-resistant materials. Boron can be extracted from open-pit mines and from brines.
