Pricing heterogeneity and transaction mode: Evidence from the French fish market

The value of product attributes for farmed oysters: A hedonic price analysis of US restaurant menus

“…To estimate the effects of the various product attributes on a good, Rosen (1974) introduced the first stage hedonic price model. This approach has commonly been used when investigating posted seafood prices at the retail level (e.g., Asche et al, 2015; Asche & Bronnmann, 2017; Bronnmann & Asche, 2016; Hukom et al, 2020; Ray et al, 2022; Roheim et al, 2007, 2011; Sogn‐Grundvåg et al, 2014) and transaction prices at the producer level (e.g., Carroll et al, 2001; Gobillon & Wolff, 2016; Kristofersson & Rickertsen, 2004; McConnell & Strand, 2000; Pettersen & Asche, 2020; Wolff & Asche, 2022).…”

“…For instance, while retail data on seafood products may contain some information on production practices using an eco‐label and origin, most of the information will be related to packet size, brand, and product forms (Asche et al, 2021; Hukom et al, 2020). At the producer level, most of this information is not available, but the focus is more specifically on production and attributes, such as gear, specific harvester or grower, size of the individual, or freshness (Sogn‐Grundvåg et al, 2021; Wolff & Asche, 2022).…”

Commodities Failing in Auctions: The Story of Unsold Cod in Norway

“…For example, large hauls when trawling may affect fish quality negatively, but information about haul sizes is generally not provided in the auction (Sogn-Grundvåg and Zhang, 2021). This implies that the quality of fish may vary among lots with the same observable attributes (Gobillon et al, 2017;Sogn-Grundvåg and Zhang, 2021;Wolff and Asche, 2022).…”

“…The heterogeneity of buyers, sellers, and buyer-seller pairs may influence prices (Gobillon et al, 2017;Oglend et al, 2022;Pettersen and Asche, 2020;Sogn-Grundvåg and Zhang, 2021;Wolff and Asche, 2022). Accordingly, we set quantile dummies for buyers, sellers, and buyer-seller pairs with respect to transaction quantities for the sample period.…”
