Before revision: We study the design of a decentralized platform in which workers and jobs repeatedly match, and their future engagement with the platform depends on whether they successfully find a match . The platform offers two types of matches to workers: an " adopted match " which entails repeatedly matching with the same job or a one-time match.
After revision: Volunteer crowdsourcing platforms, such as food URLanizations, match volunteers with tasks which are often recurring. To ensure completion of such tasks, platforms frequently use a commitment lever known as " adopted match " which entails repeatedly matching with the same job or a one-time match.
