  Users of search engines often abandon their searches. Despite the high frequency of Web search abandonment and its importance to Web search engines, little is known about why searchers abandon beyond that it can be for good or bad reasons. In this paper, we extend previous work by studying search abandonment using both a retrospective survey and an in-situ method that captures abandonment rationales at abandonment time. We show that although satisfaction is a common motivator for abandonment, one-in-five abandonment instances does not relate to satisfaction.

• The geography of start-ups: Something in the air | The Economist

  Economic theory suggests four main reasons why firms in the same industry end up in the same place. First, some may depend on natural resources, such as a coalfield or a harbour. Second, a concentration of firms creates a pool of specialised labour that benefits both workers and employers: the former are likely to find jobs and the latter are likely to find staff. Third, subsidiary trades spring up to supply specialised inputs. Fourth, ideas spill over from one firm to the next, as Marshall observed. But there are also forces that encourage companies to spread out. One is the cost of transporting their products to widely dispersed customers. Another is rents, which rise when firms cluster together.
