E-Word-of Mouth for Money—An Examination of the Impact of the Payment Timing on Knowledge Contribution Quality

Knowledge sharing is a determinant for online platforms to run their business. Several strategies have been proposed to increase knowledge sharing, among which monetary incentive is commonly used.

This has direct implications for practitioners considering the usage of gifts to elicit online ratings
