Inferior search engine’s optimal choice: Knowledge-sharing service versus search quality

作者：

Highlights：

• We analyze when an inferior search engine should introduce a Q&A service to better compete with a superior search engine.

• An inferior search engine should introduce a Q&A service when the search quality difference is small.

• An inferior search engine should improve its search quality when the search quality difference is large.

• The optimal search quality of an inferior search engine also depends on the amount of online information.
