Rising Market Concentration and the Decline of Food Price Shock Pass-Through to Core Inflation
Using a vector autoregression that allows for time-varying parameters and stochastic volatility, we show that U.S. core inflation became 75 percent less responsive to shocks in food prices since the late 1970s. The decline in the pass-through of food price shocks to inflation is a result of a decline in both volatility and the persistence of food price changes in inflation. This decline in pass-through coincides with a period of increasing concentration in the food supply chain, especially among U.S. grocery retailers and distributors. We find that 60 percent of the variation in pass-through ...

A staggered pricing approach to modeling speculative storage: implications for commodity price dynamics
This paper embeds a staggered price feature into the standard speculative storage model of Deaton and Laroque (1996). Intermediate goods inventory speculators are added as an additional source of intertemporal linkage, which helps us to replicate the stylized facts of the observed commodity price dynamics. Incorporating this type of friction into the model is motivated by its ability to increase price stickiness which, gives rise to a higher degree of persistence in the first two conditional moments of commodity prices. The structural parameters of our model are estimated by the simulated ...
