In Vino Economica
Dr. Gokcekus’s research on the economics of wine markets
Reputation & Expert Ratings
Key questions:
Do expert ratings create measurable price premiums?
Does belonging to an appellation generate economic value?
How durable are regional reputation premiums?
This research analyzes price elasticity relative to expert scores, information asymmetry, and signaling effects in differentiated product markets.
