The present study aims to investigate the dynamics of primary commodity prices and the role of speculation over time. In particular the relationship between speculation and price volatility on the one side, and the linkage between excessive speculation and price volatility on the other side, is...

The present study aims at modelling market risk for four commodities, namely West Texas Intermediate (WTI) crude oil, natural gas, gold and corn for the period 2007-2017. To this purpose, we use Extreme Value Theory (EVT) together with a set of Conditional Auto-Regressive Logit (CARL) models to...

The aim of this study is to investigate the possible contagion risk coming from energy, food and metals commodity markets and to assess risk spillovers from biofuel to food commodity markets and from crude oil to food markets. To this purpose, we use the delta Conditional Value-at-Risk ΔCoVaR)...

The role of futures markets in stabilizing spot prices has been extensively discussed. Nevertheless, the ability of these markets to achieve the stabilizing function significantly depends on whether they are 'efficient' in the sense that futures prices 'fully reflect' the available information....
