Im Rahmen des CDSB Research Seminars freuen wir uns, Herrn Dr. Dominik Gutt am Mittwoch, den 29.03.2023, von 12:30 bis 13:30 Uhr von der Erasmus University Rotterdam zum Thema   „Do Non-Fungible Tokens (NFTs) Affect Prices of Physical Products? Evidence from Trading Card Collectibles“ bei uns begrüßen zu dürfen.


Since the beginning of 2021, non-fungible tokens (NFTs) have gathered considerable attention. The introduction of NFTs and the high prices that many have been auctioned off for raise the question how the introduction of NFTs affect the prices of their physical co­unterparts. In this work, we use data from eBay to evaluate how the prices of basketball trading card collectibles are affected by the introduction of a related NFT market named „NBA Top Shot“. We find that the introduction of NFT collectibles causes the prices of physical collectibles to decline by 5.2% (US$ 27.7). By applying a natural language processing model, we identify the player and the year that each card refers to and we find evidence suggesting the presence of a substitution effect: The introduction of NFTs of currently-active players reduces the prices of physical cards of currently-active but not of retired players, while the substitution effect even extends to currently active players without NFTs. We study each agent's (buyers and sellers) reaction to the introduction of NFTs and we find that buyers' willingness to pay drops by 10.3% and sellers' reservation prices decrease by 5%. Further analyses suggest that our results are driven by a technology rather than an attention effect, while we estimate how key NFT market characteristics (consistent physical quality of goods, „built-in“ reputation, and digital scarcity of goods) shape the impact of NFTs on the market of physical collectibles. Lastly, we calculate the economic implications for marketplaces of physical collectibles, conduct various tests to validate our identification strategy using multiple data sets, and discuss how we contribute to the literature and management.
