This paper analyzes the interaction between price and inventory decisions in an oligopoly industry and its implications for the dynamics of prices. The work extends existing literature and especially the work of Hall and Rust (2007) to endogenous prices and strategic oligopoly competition. We...

When deciding to buy differentiated products, a compromise is sometimes made between preferred characteristics of the good and its environmental properties....
