  This paper contributes to the literature on hedonic models in two ways.
First, it makes use of Queyranne's reformulation of a hedonic model in the
discrete case as a network flow problem in order to provide a proof of
existence and integrality of a hedonic equilibrium and efficient computation of
hedonic prices. Second, elaborating on entropic methods developed in Galichon
and Salani\'{e} (2014), this paper proposes a new identification strategy for
hedonic models in a single market. This methodology allows one to introduce
heterogeneities in both consumers' and producers' attributes and to recover
producers' profits and consumers' utilities based on the observation of
production and consumption patterns and the set of hedonic prices.
