In a spatial competition model, changes in firms' competitive behaviour may occur when the hypothesis that individual gross surplus is positive in equilibrium is relaxed. We prove that there exists a region of the relevant parameter where firms' behaviour mimics collusion, while in another range...

We investigate the bearings of the level of demand on firms’ optimal locations and prices in a linear model of spatial differentiation with quadratic disutility of transportation. We show that demand affects both optimal prices and optimal locations of firms, in that firms increase product...
