We develop a dynamic entry model of multi-store oligopoly with heterogeneous markets, and estimate it using data on hamburger chains in Canada (1970-2005). Because more lucrative markets attract more entry, firms appear to favor the presence of more rivals. Thus unobserved heterogeneity across...

This paper presents a new decomposition approach for measuring deterrence motives in dynamic oligopoly games. Our approach yields a scale-free and interpretable measure of deterrence motives that informs researchers about the proportion for which deterrence motives account of all entry motives....
