• Utilized administrative and survey data to track changes in personal income expectations and spending responses.
• Focus on financially unconstrained consumers to determine the influence of income expectations on their spending.
• Credit limit extensions increased total spending and income expectations significantly.
• The spending response weakens by approximately 30% when accounting for changes in income expectations.
• For financially unconstrained consumers, about two-thirds of the spending response is attributed to expectation changes.
