The impact of monetary rewards on online reviews
Several online retailers provide monetary rewards to users for sharing their opinions on their review platforms. In a study published in Information Systems Research in 2018, Krannert PhD, Professor Warut Khern-am-nuai and Krannert Professors, Kannan and Ghasemkhani, take advantage of the sudden introduction of monetary incentives by a prominent American retailer to study how such rewards affect user behavior. Utilizing a natural experiment design, they find that in the presence of monetary incentives, users write more positive and lower quality reviews. They also find that previously active members contributed fewer reviews after the rewards were introduced.
