There is a lack of consensus on the importance of various drivers of long-run commodity prices. This column analyses a new dataset of prices and production for 15 commodities, including metals, agricultural goods, and soft commodities, between 1870 and 2015.

While demand shocks have gained importance over time, commodity supply shocks have become less relevant.
