Food prices have received a lot of attention recently. Understandably, much of the attention is on recent developments and short term prospects. But in this blog post I try to look back at some longer term trends, in order to look further ahead.
Since the early 2000s, food related prices have trended up (Figure 1). The deflator of agricultural value added has risen 8% per year on average since 2000, after falling during the second half of the 1990s. Producer Price Index (PPI) food prices (factory gate) have risen much less because prices of other inputs into the food processing industry have gone up less and rapid productivity growth in food processing has dampened the transmission of higher raw food prices.
