摘要：In this paper,we investigate two competing pay-tv platforms or free-to-air media platforms that consist of two groups of agents:viewers and *** pay-tv platforms can receive revenues from charging viewers pay-per-view prices and advertising,while the free-to-air platforms can only obtain all incomes from *** discuss and compare advertising intensities and program content provisions of the two competing media *** findings show that if the extent to which viewers dislike advertising(the nuisance for advertising)is more massive than the marginal benefit that advertisers receive from an additional viewer,the pay-tv stations tend to maximally differentiate their program content and charge the viewers higher pay-per-view *** the nuisance approaches to the marginal benefit,however,both stations should offer similar program content,and charge the viewers lower prices under certain ***,if both platforms provide duplicated content,they should subsidize the *** contrast,we show that the free-to-air media platforms never duplicate program content with a positive nuisance for advertising,and tend to offer maximal differentiated content if the nuisance is sufficiently ***,we reveal that if the viewers greatly dislike advertising(care less about advertising),the advertising volume of the pay-tv platforms is lower(higher)than that of the free-to-air ***,we extend our base model to the case in which a pay-tv platform competes against a free-to-air station,and numerically show that the profit of the pay-tv platform may be larger or smaller than that of the free-to-air station.
