Payment Mode Equivalence Under Unconstrained Liquidity
RCTReview
Evaluating whether individuals experience present bias or binding borrowing constraints when receiving wealth requires comparing labor responses across lump-sum windfalls and multi-year annuity installments. Identifying differences in immediate work reductions tests models of time-inconsistent behavior.
Picture this
Imagine two workers who receive the exact same total reward value: one gets the full stack of cash immediately, while the other gets a steady monthly check for twenty years. Because both workers can easily save or spend as needed, both cut back their work hours by the exact same amount each year, proving that people act as farsighted planners unaffected by how the payouts are structured.
What the evidence says
Dynamic labor supply responses over a 10-year follow-up period show statistically indistinguishable trajectory patterns between lump-sum payout recipients and monthly annuity recipients, rejecting severe present bias or binding borrowing constraints.
- Who was studied
- N = 3,829 Triss lottery TV show participants in Sweden (3,260 lump-sum winners and 569 monthly installment winners).
- How
- Event-study econometric comparison tracking 10-year post-win annual pre-tax earnings trajectories between lump-sum winners and monthly annuity winners (converted to net present value at a 2% discount rate).
What to do
Treat lump-sum and structured annuity wealth transfers as economically equivalent when forecasting aggregate worker labor supply adjustments over multi-year horizons.
From the source
"If winners have a significant bias to the present and Triss-Monthly winners are unable to borrow against their future income stream, we would expect bigger immediate responses from lump-sum prizes. Yet the response patterns for the two Triss lotteries are quite similar."
