Fundamentals, speculation or macroeconomic conditions? Modelling and forecasting Arabica coffee prices

We analyse the role played by market fundamentals, speculation and macroeconomic conditions as empirical determinants of price changes in Arabica coffee. We combine model averaging techniques to explain historical patterns with an in-depth analysis of out-of-sample predictability of Arabica coffee prices using fundamentals as well as macroeconomic and financial variables. Our results indicate that variables related to global macroeconomic and financial developments contain valuable information to explain the historical pattern of coffee price developments, as well as to improve out-of-sample predictions.
