We extend previous models of duopolies by introducing regions. This analysis highlights how incentives to conduct process R&D are affected by increasing regional distance, and the effect that agglomeration (in terms of population) has on two firms producing a high- and low-quality good...

Most models of duopolies with a spatial dimension refer to the 'linear' or 'circular' city. Moreover, in duopoly models with innovations, the spatial dimension is usually dropped. We bridge this gap by constructing a model with two regions, each hosting production of a differentiated quality...
