This paper examines the impact of payment choice on charitablegiving with a door-to-door fund-raising field experiment. Respondentscan donate cash only, use debit only, or have both options. Cash donations have lower visibility vis-a-vis solicitors than debit card donations. When debit replaces...

We manipulate workers' perceived meaning of a job in a field experiment. Half of the workers are informed that their job is important, the other half are told that their job is of no relevance. Results show that workers exert more effort when meaning is high, corroborating previous findings on...
