We start out reviewing the justification for press subsidies. The social value of journalism can be larger than what the newspapers are able to extract because of knowledge externalities, public good characteristics of investigative journalism and non-appropriability of consumer surplus. A free market will then underinvest in journalism. Problems related to economies of scale and scope further imply that the number of newspapers and their circulations may be too small, while advertising can give newspapers too strong incentives to aim for the mass market. According to the media economics literature, a preferential VAT regime provides higher differentiation incentives for existing newspapers, while a tax deduction for editorial expenses is well suited to increase journalistic investments. Micro economic theory further indicates that fixed transfers is the most efficient instrument to reduce entry barriers and avoid newspaper mortality, and that a subsidy per copy sold will increase circulation. We end the article by summarizing empirical evidence on the effects of media support.
