Abstract
Rural Malawian households adjust labor along two margins of a single portfolio: churning occupations over time (transition) and holding several income activities at once (concurrent diversification). Annual surveys collapse the year into a single observation and record sequential within-year reallocation as though it were a stable diversified portfolio. Using a monthly panel of more than 5400 households (2020–2024), I separate the two and trace their distinct and opposing food-security signatures. A household’s diversification is assembled mostly from different members each holding a distinct, short-duration activity, rather than from one person juggling several activities at once (individual multitasking), and primary occupations churn horizontally through low-return casual labor ( ganyu ). Decomposing the within-year food-security association into two offsetting flows reveals that transitions track deterioration — disproportionately for the asset-poor — while stable diversification is protective; I interpret these associations descriptively. An annual instrument of the kind used by the World Bank’s Living Standards Measurement Study (LSMS), built from the same households, recovers the consumption–diversification gradient but cannot separate the two flows—even though they call for opposite responses: distress-driven switching marks households that need to be shielded from being pushed into low-return work, whereas stable diversification is worth protecting and encouraging.
