We measured the impact of training on demand for observable and unobservable dimensions of quality, at harvest and in the lean season. We found that the control group who was not trained valued sorted grains (an indicator of observable quality) only. At harvest, both trained and untrained consumers placed statistically equal premiums on food safety labeling (an indicator of otherwise-unobservable quality). However, in the lean season, untrained consumers’ premiums for food safety labeling disappeared, while trained consumers’ premiums for food safety labeling increased. 收起
