Evidence for Practice• This research shows that modest compensation (2 euros per hour, similar to a time-bank voucher) does not have a significant effect on people ' s willingness to coproduce public services. Therefore, governments should be cautious in offering financial incentives to stimulate people to coproduce. • Even substantial financial incentives (10 euros per hour, comparable to the net income of a professional teacher) have only very small effects (6 percentage points) on people ' s willingness to coproduce. Therefore, governments are well advised to explore alternative possibilities for stimulating citizens ' willingness to coproduce.• This research indicates that people ' s motivation to coproduce is not crowded out by financial incentives.However, given the relatively small effect of financial incentives on people ' s willingness to coproduce, governments are advised to strengthen intrinsic public service and prosocial motivations (e.g., solidarity, charity, etc.) of potential coproducers instead of promoting coproduction by introducing financial incentives.
