Seasonal Labor Supply and Liquidity Constraints
RCTReview
In rainfed agricultural economies, seasonal fluctuations in crop cycles create severe food shortages and cash bottlenecks, altering worker reservation wages and responsiveness to piece-rate incentives.
Picture this
Think of a household during the dry season after harvest versus the lean pre-harvest season. During the lean season, families run out of food and savings, creating an urgent need for cash to buy daily meals. As a result, workers accept lower minimum pay rates and work harder for immediate cash than they do during post-harvest months when food reserves are full.
What the evidence says
High-season workers facing acute liquidity constraints and lean food months report higher recent daily wages (344.6 MWK vs 257.7 MWK, p < 0.01) and sort 0.48 more units per day (p < 0.01). Self-reported cash-generating outside options significantly lower minimum reservation rates within worker.
- Who was studied
- N = 355 participants (1,005 worker-days) in the low labor demand season and N = 334 participants (870 worker-days) in the high labor demand season in rural Malawi.
- How
- Seasonally stratified field experiment comparing reservation wages (BDM WTA) and daily productivity across agricultural crop cycles.
What to do
Account for agricultural seasonality and household liquidity stress when forecasting labor supply elasticity and setting seasonal piece rates.

"When the value of money is high, during the high labor demand season, workers have a lower WTA and are more responsive to incentives."
