“…Our finding suggests that there is heterogeneity in the cognitive processes (or mental models) people use to convert public news into personal probability beliefs, in accordance with some of the disagreement literature we mentioned above. The results on changes in heterogeneity complement recent empirical investigations that show substantial heterogeneity in stock market expectations of individual investors (Vissing‐Jorgensen, 2003) as well as households (Calvet et al , 2007, 2009a,b; Dominitz and Manski, 2007; Kezdi and Willis, 2008; Hurd et al , 2009; Gouret and Hollard, 2010). This paper adds new results to this empirical literature by showing that the stock market crash and the financial crisis had significant effects on average expectations, average uncertainty, and, perhaps most importantly, the heterogeneity of expectations.…”
