Our one-period model of investors with heterogeneous preferences differs from heterogeneous-information models in key ways. First, in our model investors do not use price to glean any information, in contrast to typical rational expectations heterogeneous information models where price is a valuable signal of other investors. Information (e.g., Lambert et al., 2007). Second, while our single-period price is the same as that in an .agree-to-disagree. Model, in our model no investor ends up being .wrong.in the sense that their beliefs were not rational (e.g., Harris and Raviv, 1993). This implies that there is no need to specify a .correct. Outcome distribution or use different distributions for different investors. Third, as the time span represented by a one-period model expands, .agree-to-disagree. Assumptions become less plausible because beliefs should converge over time as information is revealed.6 Heterogeneous preferences, in contrast, provide no rationale for long-term convergence. Information, however still plays an important role when investors have heterogeneous preferences.
