Seasonal Labor Supply and Liquidity Constraints

In Simple Words

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.

Research question

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.

Participants

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.

Study Design

Seasonally stratified field experiment comparing reservation wages (BDM WTA) and daily productivity across agricultural crop cycles.

Results

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.

Takeaway

Account for agricultural seasonality and household liquidity stress when forecasting labor supply elasticity and setting seasonal piece rates.
