| Abstract: | Under rationing of a public service due to its lower price and higher quality, the “privatization” could be regarded as a reduction in the capacity of the public service. We develop a model of mixed duopoly in which the service is vertically differentiated, a public firm is in a Stackelberg leader position, rationing happens, and the market is not covered. In one of two possible cases, it is shown that any reduction in the capacity of a public service will lower total surplus unless the price of the public service is too low and its quality is too high. |
