The heterogeneous effects of COVID‐19 on Canadian household consumption, debt and savings
Bibliographic record
Abstract
This paper develops an agent-based model to quantify the impact of COVID-19 on household debt and savings. To build a representative cross-section of households that vary by income, debt portfolios and consumption baskets, we merge data from the Survey of Household Spending and the Survey of Financial Security. We construct paths for consumption and employment over the crisis, accounting for heterogeneous risk of unemployment across demographics, government transfers, and substitution between expenditure categories that vary in contact intensity. Our model simulations yield a heterogeneous effect of COVID-19 across the income distribution. Low-income households face the highest risk of unemployment, but transfers provide generous income replacement. Middle-income job losers see the fastest rise in debt because transfers only partially replace lost income. Most unplanned savings are accumulated by high-income households that face lower risk of unemployment and larger declines in hard-to-distance spending. We find the rise in savings could generate a brief jump of nearly 6% of monthly consumption.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
