In this study, we were able to work with a vendor to implement an experimental design in an actual market setting. This design enabled consumers to reveal their preferences for cups of freshly brewed coffees, of which fair trade was one of the varieties. The results show that fair trade coffee exhibits a lower own-price elasticity than similar conventional products. Furthermore, conventional coffee varieties do not see a large increase in their proportion of buyers as the price of fair trade increases. These findings suggest that ethical attributes may be the primary influence on coffee purchasing behavior for most consumers of fair trade coffee. These purchasers were presumably driven more by a desire to consume socially responsible products and may not be motivated by price.
