The New York Times and the Market for Local Newspapers
研究发现《纽约时报》全国发行策略导致地方报纸在大学学历读者中销量下降，促使地方报纸转向本地报道以吸引非大学学历读者。
Recent technological advances have dramatically lowered the cost of transmitting information over large distances. In the late 1990s, the New York Times implemented a national distribution strategy, expanding delivery in over 100 cities. Using cross-sectional and longitudinal data on local newspaper circulation, Times penetration, and local newspapers characteristics, we find that as Times circulation grows in a market, local newspaper circulation declines among college-educated readers. Local newspapers reposition toward local and away from national coverage, raising circulation among individuals without a degree. Availability of national newspapers in local markets changes the relationship between local preferences and local products.
