I analyze questions and answers from Google Answers. More experienced answerers provide answers with the characteristics askers most value, receiving higher ratings as a result. Answerer earnings increase in experience. Answerers who focus on particular question categories provide answers of higher quality but earn lower pay per hour. Answers provided during the business day receive higher payment per hour, but more experienced answerers tend to favor work at other times . ( JEL J22, J31, L14)
