Attracting the Rival’s Customers in a Model with Switching Costs

We consider the option of a firm’s honouring the rival’s coupons in a duopoly model in which products are differentiated by both characteristics and a switching cost. A firm may honour its rival’s coupons to increase its market share only if its previous market share is less than one‐half but not too low and, as a result, the market share is increased but only up to one‐half.
