“…Due to this, the prices of agricultural inputs trigger a long sequence of factors in contemporary agricultural systems, adding to their dynamics and complexity. Several dedicated studies (De Roest, Ferrari & Knickel, 2018;Morales, 2018;Lanfranchi, Giannetto, Rotondo, Ivanova & Dimitrova, 2019;Yan, Cai, Lin & Ambaw, 2021;Viganò, Maccaroni & Righi, 2022) claim that the analysis of inputs price indices of agricultural products makes it necessary to render a no lesser attention to the degree of volatility of this category of prices, which, in agriculture as a complex economic system, must be able to reflect the sector's capacity to mobilise specific resources. When analyzing the drivers of grain price volatility, (Gaetano, Emilia, Francesco, Gianluca & Antonio, 2018) point out that a thorough analysis of the critical factors of price instability is mandatory, because the interpretation of the curve of prices of farm inputs will help predict the role and dynamics of demand and supply for agricultural produce in complex economic markets.…”
