Using level scanner (ACNielsen Homescan) all cereals inelastic changes in prices.The expenditure elasticity slightly above unity ready-to-eatcereals suggesting on increases households will al-locate proportionally more whole-grain ready-to-eat less othercereals.Keywords: AIDS model, Bayesian econometrics, censored, grains.JEL Classi cation: C11; C34; D12.
