The effects of increasing the certainty of punishment

Abstract

Since 1993, Zurich's suburban transport systems have operated without attendants on the trains, and passengers' tickets were checked only sporadically. After increasing worries about crime and passenger safety on suburban trains, it was decided, in order to reduce fear of crime, to reintroduce attendants on all trains after 9 p.m. As well as dealing with order on the trains, these attendants had to check the tickets of all passengers. The programme was launched in June 2003, and once it was fully implemented the resources devoted to ticket checks and, thus, the number of passengers controlled after 9 p.m. rose by roughly 1500 percent. However, ticket checks remained stable and sporadic during day-time hours. The programme led to a dramatic reduction in fare-dodging on trains operating during the evening and, as an unexpected outcome, during day-time hours. The decline in fare evasion eventually levelled off. The results suggest that certainty of punishment works as a deterrent in a non-linear way, and that benefits from increased certainty can be maximized if checks are concentrated on critical hours and areas.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
