The Cost Impact of Spam Filters: Measuring the Effect of Information System Technologies in Organizations
Source: University of Hamburg
More than 70% of global e-mail traffic consists of unsolicited and commercial direct marketing, also known as spam. Dealing with spam incurs high costs for organizations, prompting efforts to try to reduce spam-related costs by installing spam filters. Using modern econometric methods to reduce the selection bias of installing a spam filter, it deployed a unique data setting implemented at a German university to measure the costs associated with spam and the costs savings of spam filters. The applied methodological framework can easily be transferred to estimate the effect of other IS technologies (e.g., SAP) implemented in organizations. The individual efficiency of a spam filter installation depends on the amount of spam that is received and on the level of knowledge about spam.
