I study the impact of aggregation of financial information from multiple financial accounts on consumer behavior. First, using transaction level data from an account aggregation company, I test the change in spending behavior of consumers that linked a new account to the app. I find that the total discretionary spending (in old and newly linked accounts) increases for users with a large percentage change in their aggregated income after linking the new account. Discretionary spending decrease with the change in aggregated spending and are not affected by the change in total balance. These results hold for the subset of users that attempted to link a new account, but the new information was successfully pulled by the app only months later due to technical reasons. Second, in a series of randomized surveys, I find that consumers perceive a single amount of monthly income or spending to be larger than the same amount divided into multiple accounts. I find no differences when splitting the total account balance into multiple accounts. Overall, the findings in this paper are consistent with the salience effect of large numbers and anchoring.
