Temporal Persistence Disproving Gift-Exchange Motivations in Workplace Training
Productivity gains from employer-provided worker amenities are often attributed to short-lived gift-exchange reciprocity—where workers temporarily increase effort out of gratitude—rather than permanent human capital acquisition.
Picture this
Think of an employer giving workers a free daily gourmet lunch. Workers initially exert extra effort out of appreciation, but over time the gratitude fades and effort returns to baseline unless their fundamental job skills were permanently upgraded.
What the evidence says
Productivity treatment effects were small and statistically insignificant during the 12-month training phase (+3.0 percentage points, p > 0.10) but grew significantly post-completion (+10.8 percentage points, p < 0.05) and persisted for 8 months, disproving gift-exchange reciprocity and confirming genuine skill accumulation.
- Who
- N = 2,703 female garment workers observed across 112 production lines over 20 months in Bengaluru, India.
- How
- Longitudinal two-stage RCT tracking daily worker efficiency during the 12-month training period (when 1 hour per week of paid time was granted) and 8 months post-completion.
What to do
Evaluate workplace training efficacy using post-program longitudinal tracking rather than during-program performance to distinguish structural skill accumulation from temporary gift-exchange reciprocity.
From the source
"The time pattern of productivity impacts (i.e., small impacts during the program, and large impacts post-program completion) does not fit well with reciprocity as a primary mechanism..."
