Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
This paper aims to explore the complex linkages and evolving structure of price volatility in the global oil, biofuels, and grain commodity markets during periods of global turbulence. With the growing urgency for energy stability amid climate change, biofuels are gaining traction as a viable alternative energy source. However, their production can significantly impact essential commodities like grains and vegetable oils, increasing food prices and heightened market volatility. We introduced a TVP-VAR frequency connectedness method to address this, analyzing data from January 1, 2013, to September 29, 2023. Our approach offers a fresh perspective on market dynamics and geopolitical risks. The study underscores the growing influence of agricultural shocks on energy markets, particularly within the ethanol sector. It confirms that the Russia-Ukraine war, a significant geopolitical event, has had a profound and enduring impact on the interconnectedness of these markets across various timeframes and frequencies. We offer concrete, actionable policy recommendations to mitigate the transmission of market shocks within the energy and food sectors, thereby bolstering investor and policymaker confidence and facilitating informed decision-making.
