In developed economies, consumers are going to accept drone deliveries because it will make the cost of purchasing an item go down.
Once, drone delivery is a common business model in developed economies, the fashion in-which drones are adopted in developing economies will be interesting to watch. In developing economies retailers follow the COD (cash on delivery) model because, a large number of the population is unbanked. These markets have a high growth potential and a low profit margin. A business that manages to cut its selling cost will be able to earn a healthy profit. However, these markets present a downside as well -- sending a $300 drone plus the value of a package, unsupervised into the market creates a potential disadvantage.
