In particular, ambient charges will not have perverse effects if an increase in the product price of one firm increases the market demand for the other firm’s product by nearly twofold. Therefore, when considering the effects of ambient charges in a duopolistic market, they might be an effective policy instrument not only under Cournot compe.. Read More»
