The price of a product depends on its characteristics and will vary in dynamic markets. The model describes a processing firm that bids in an auction for a heterogeneous and perishable input. The reduced form of this model is estimated as an expanded random parameter model that combines a nonlinear hedonic bid function and inverse input demand functions for characteristics. The model was estimated by using 289,405 transactions from the Icelandic fish auctions. Total catch and gut ratio were the main determinants of marginal prices of characteristics, while the price of cod mainly depended on size, gutting and storage.
