Inattention in Individual Expectations

This paper investigates the expectations formation process of economic agents about infl ation rate. Using the Market Expectations System of Central Bank of Brazil, we perceive that agents do not update their forecasts every period and that even agents who update disagree in their predictions. We then focus on the two most popular types of inattention models that have been discussed in the recent literature: sticky-information and noisy-information models. Estimating a hybrid model we fi nd that, although formally fi tting the Brazilian data, it happens at the cost of a much higher degree of information rigidity than observed.
