Labor Supply Smoothing via Wage Worker Insurance
RCTClinical Trial
Landless agricultural laborers depend on daily wages and lack financial mechanisms to smooth consumption during climate shocks, forcing them to supply more labor during low-wage drought periods [2, 10]. When weather index insurance is offered directly to wage laborers, payout distributions during adverse weather offset lost earnings and allow workers to withhold labor supply, supporting equilibrium market wages [1, 11, 12].
Picture this
Imagine a group of day laborers who must sell bottled water on the street every day just to buy dinner. When a severe heatwave hits and water prices crash, they normally have to work twice as many hours to earn enough money for food. However, if each worker receives an emergency cash payout from a weather relief fund whenever a heatwave occurs, they do not need to work extra hours on the street. Because fewer workers are competing for street corners, the local price of daily labor stays high, which indirectly helps even those day laborers who did not buy into the relief fund.
What the evidence says
Insured wage workers receiving insurance payouts had a labor participation rate 28.5 percentage points lower than uninsured peers at median rainfall shock [18], working 15.4 fewer days in the season [19]. A 10% increase in laborer insurance marketing raises village wages by 24.7% in payout states [20].
- Who was studied
- 3,678 landless agricultural wage workers aged 25–49 across 42 randomized treatment villages in rural India [4, 5].
- How
- Two-stage clustered randomized controlled trial tracking labor force participation rates and total days worked across delayed-monsoon payout versus non-payout villages [6, 13-17].
What to do
Offer micro-index rainfall insurance directly to landless wage workers to prevent distress labor supply and insulate general equilibrium wages against climate downturns.
