We study how defaults affect charitable donations. In a field experiment that was conducted on a large online platform for charitable giving, we exogenously vary the default options in the donation form in two distinct choice dimensions. The first pertains to the primary donation decision,...

The motivation value of confidence postulates that individual effort provision is increasing in beliefs on one's own productivity.
