A Unifying Differential Game Of Advertising And Promotions
The literature on advertising and promotions can be divided in two categories. A first group of models assume that promotion contributes (positively) to the goodwill towards the product, and a second group assumes that promotions reduce that goodwill. In this paper we build a differential game model where the impact of promotion on goodwill is endogenously determined. We conduct a comparative dynamics exercise. An unexpected result is that an increase in the sensitivity of sales to goodwill can lead to a decrease of the equilibrium level of sales.
