Analysis of the Efficiency and Effectiveness of Filtering with the Approach of Economic Analysis of Law

One of the ways to control and prevent crime is cyber filtering or content filtering. Filtering has been widely used in Iran. Applying filtering to prevent crime, along with the benefits it may bring, has its expenses and costs. In order To limit resources and avoid unwanted costs caused by filtering, it is necessary to measure and evaluate the costs and benefits caused by filtering. In this regard, the present article aims to discuss filtering with the descriptive-analytical method and with the approach of economic analysis of law to "determine efficiency". In this way, the two main components of productivity, i.e. "efficiency" and "effectiveness" are the filtering evaluation indicators in this study. The findings of this research show that first; Content filtering, with all the high costs that imposed on the society for its implementation and as a result of its implementation, has had few benefits, so it does not have the necessary efficiency. Secondly; filtering lacks the expected and desired effectiveness for many technical and social reasons. The conclusion and theory of this article is that it is necessary to revise the current content filtering policies and use other methods of crime prevention in cyberspace.
