Established analysis of labour market commuting are based on random choice models and gravity type models. In these models generalised transport costs are formulated as exponential or loglinear distance-dependent functions. This paper presents empirical observations that imply that...

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...
