4.Nash equilibrium
Recent studies in marketing have demonstrated that in many industries retailers have increased their power relative to manufacturers over the past two decades. Especially,for durable goods such as appliances and automobiles, the retailer has more influence on the consumer’s purchase decision.

In this game,the manufacturer holds extreme power and has almost complete control over the behavior of the retailer.

Next the optimal value of q and t are
determined by maximizing the manufacturer’s profit subject to the constraint imposed by Eq(5).Hence,the manufacturer’s problem can be formulated as

its negative coefficient in the objective. A Nash equilibrium advertising scheme can be obtained by simultaneously solving the following conditions:

In this section,we relax the leader-follower relationship and assume a symmetric relationship between the manufacturer and the retailer. The manufacturer and the retailer simultaneously and noncooperatively maximize their profits with respect to any possible strategies set by the other member .

We can observe that:
So the manufacturer can use his co-op advertising policy and his national brand name investment to induce the retailer to increase or decrease local advertising expenditure at a level he expects.
The main reason for a manufacturer to use co-op advertising is to strengthen the image of the brand and to motivate immediate sales at retailer level.
