Experimental Design

Experimental Design
We randomly assigned participants to either a control group or three treatment groups.
Experimental Design Details
In this experiment, participants are randomly assigned to one control group or to one of two treatment groups. The control group receives a scenario in which participants obtain an additional income of 100,000 yen in cash. The treatment groups receive scenarios in which participants obtain the same amount either in the form of a time-limited gift certificate or through a cashless payment method such as electronic money, QR code payment, or credit card. We then examine how this additional income affects participants’ spending behavior over the subsequent three months. Spending is defined to include donations but excludes debt repayment.
Randomization Method
Stratified randomization by a survey company. The strata are based on sex (male/female) and age (20-29/30-39/40-49/50-59/60-79).
Randomization Unit
Individuals
Was the treatment clustered?
No
