We study the optimal manipulation rules of a public firm’s objective function in a mixed oligopoly with imperfect product substitutability. We start with a baseline duopoly model and compare the solutions under quantity and price competition, and the way they are affected by product...

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...

We consider a differentiated duopoly and endogenise the firm choice of the strategy variable (price or quantity) to play on the product market in the presence of network externalities. We model this choice by assuming both competition between entrepreneurial (owner-managed) firms and competition...
