DebateThe effect of news aggregators on the news media, and especially on the quality of journalism is a significant concern
There are two type of arguments in this debate:
• News aggregators “steal” traffic from news sites. ⇒ lower quality
• News aggregators “help” newspapers to find readers for the best contents. ⇒ higher quality
![Page 15: News Aggregators and Competition among Newspapers in the …idei.fr/sites/default/files/medias/doc/conf/pos/papers... · 2012-04-17 · Stylized Facts I Advertising Revenue of Newspapers](https://reader034.vdocuments.mx/reader034/viewer/2022042210/5eaea4f2ba3687211e25443d/html5/thumbnails/15.jpg)
Main ResultsIf the increase in attention from high quality contents is large enough, the presence of aggregator would
• changes strategic interactions of quality choices of newspapers from strategic substitutes to strategic complements.
• lead to specialized newspapers
• increases the average quality of newspapers
• improve the consumer surplus
• increases(decreases) the profit of newspapers if cost of investment is low(high).

• For a given issue, if the quality of both newspapers are the same (high or low) the aggregator picks one randomly.

Comparison: Consumer Surplus and Profit
Proposition 8. If the presence of the aggregator leads to the
specialization equilibrium
i) Consumer surplus increases, .
ii) The profits of newspapers increases if the cost is low, and
decreases otherwise

Discussions• What matters is not c, but c/ω , where is ad revenue per attention. As
Internet decreases ω, aggregators likely to reduce newspapers profit.
• For n(>2) newspapers, max differentiation eq can exist even when δ is small, which is consistent with the fact that fewer than 1 percent have opted out of Google News.

Conclusion• The presence of aggregator may lead to specialized newspapers
• The aggregator changes strategic interactions of quality choices of newspapers from strategic substitutes to strategic complements.
• The presence of the aggregator may result in an increase in the quality.
• The aggregator is beneficial for consumers, where as it may harm newspapers.
• Even if the aggregator harms newspapers, each newspaper may prefer to keep its link with the aggregator.
