Who Owns the Media?
研究了97个国家的媒体所有权模式，发现最大媒体公司几乎都由政府或私人家族拥有，且政府所有权在广播领域比印刷媒体更普遍。数据支持公共选择理论，即政府所有权会损害政治和经济自由。
We examine the patterns of media ownership in 97 countries around the world. We find that almost universally the largest media firms are owned by the government or by private families. Government ownership is more pervasive in broadcasting than in the printed media. We then examine two theories of government ownership of the media: the public interest (Pigouvian) theory, according to which government ownership cures market failures, and the public choice theory, according to which government ownership undermines political and economic freedom. The data support the second theory.
