Characterizing the Common Prior Assumption
Abstract
The common prior assumption (CPA) is one that, up until quite recently, was almost an article of faith among economists. This assumption says that differences in beliefs among agents can be completely explained by differences in information. Essentially, the picture is that agents start out with identical prior beliefs (the common prior) and then condition on the information that they later receive.
