Conventional VAR-based volatility spillover measures rely on homoskedasticity and single-Gaussian assumptions, limiting their ability to capture structural breaks and heterogeneous shocks during crises. This study develops a flexible framework to analyze volatility transmission in U.S. commodity...

The paper seeks to answer the question of how price forecasting can contribute to which techniques gives the most accurate results in the futures commodity market. A total of two families of models (decision trees, artificial intelligence) were used to produce estimates for 2018 and 2022 for 21-...

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...

In July 2024, the European Union (EU) and the Serbian government signed a strategic raw materials partnership. For the EU, this cooperation represents an important step towards diversifying its supply chains and strengthening economic partnerships in its neighbourhood. Serbian President...

In the global transition to cleaner energy, the role of international mineral trade, which is subject to price volatility and geopolitical competition, is crucial yet complex. This study investigates the dynamic correlation between clusters of international mineral trade (both exports and...

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...
