Abstract
This paper considers the strategic (in)attention of multi-product firms with endogenous product range choice and introduces free entry prior to firms' strategic choices on attention or inattention. We find that within-firm cannibalization of multi-product firms plays a key role in determining firms' strategic behavior. Furthermore, with free entry, we identify a single threshold that determines whether all the entrants are attentive or inattentive, and hence the market structure is unique almost everywhere.
期刊介绍：
Operations Research Letters is committed to the rapid review and fast publication of short articles on all aspects of operations research and analytics. Apart from a limitation to eight journal pages, quality, originality, relevance and clarity are the only criteria for selecting the papers to be published. ORL covers the broad field of optimization, stochastic models and game theory. Specific areas of interest include networks, routing, location, queueing, scheduling, inventory, reliability, and financial engineering. We wish to explore interfaces with other fields such as life sciences and health care, artificial intelligence and machine learning, energy distribution, and computational social sciences and humanities. Our traditional strength is in methodology, including theory, modelling, algorithms and computational studies. We also welcome novel applications and concise literature reviews.
