This study investigated consumers' valuation of geographical indication (GI) and protected geographical indication (PGI)‐labeled rice in Bangkok using a non‐hypothetical experimental auction in a field setting. We also examined the effects of sequentially providing information about geographical indications on product valuation. The results suggest that consumers are willing to pay premiums for rice with geographical certifications, with the highest premium for the rice with both GI and PGI certifications. The provision of detailed information about the geographical indications further increases the premiums. However, consumers suffer a welfare loss under the current high market prices for rice with geographical certifications. A price reduction of approximately 10 percent would be needed to gain consumer welfare from the introduction of GI and PGI certification.

消费者对带有地理标志的食品的评估：以曼谷的霍姆米饭为例*

这项研究使用非假设性的实验性拍卖在曼谷调查了消费者对曼谷地理标志（GI）和受保护的地理标志（PGI）标记的大米的评估。我们还研究了顺序提供有关地理标志信息对产品评估的影响。结果表明，消费者愿意为具有地理认证的大米支付保险费，而对具有GI和PGI认证的大米则支付最高的保险费。提供有关地理标志的详细信息进一步增加了保费。然而，在当前具有地理认证的大米的高市场价格下，消费者遭受了福利损失。
