Promised Incentives in Media Research: A Look at Data Quality, Sample Representativeness, and Response Rate
研究了媒体研究中承诺激励对数据质量、样本代表性和回复率的影响，发现激励能提高回复率且不损害代表性和质量，甚至因提升受访者注意力而改善回复质量。
The authors examine the effects of using promised incentives to increase respondent compliance in media research. The impact of promised incentives on data quality, sample representativeness, and response rate is studied. The use of promised incentives is found to increase response rates without lessening sample representativeness or response quality. In fact, the data suggest that incentives heighten response quality because they increase the attention respondents devote to the task for which they are being paid.
