If you find it interesting, you should look into Intel and their difficulties to shift from 14nm to 10nm production and how that affects the consumer prices.

Thats somewhat related and should give you a sense of the inner workings of the industry and price fluctuations.

To me it seems that the process of manufacturing 10nm chips is too costly and ineffective with current techniques that result only a portion of the chips of that batch to pass the quality standards. So manufacturers need to shift to a more efficient and sophisticated processes which is a huge invest that the consumers are going to pay at the end of the day, but the prices are going to go down eventually.
