اندازه گيري فساد مالي در ايران با استفاده از منطق فازي (رويكرد اقتصادي)

Measuring Corruption in Iran by Using Fuzzy Logic (Economic Approach)

Corruption is as a complex and multidimensional phenomena with the various causes and harmful effects, where the domain of which could be spread from individual act to overall abuse at every pillar of political and economic structures. Despite the complexity and difficulty of the subject, in the current years, many studies have been done in order to understand the roots, causes and methods of measuring corruption and to offer policies by international societies. This article by using fuzzy logic, explains how to model the economic relations, describes a new algorithm for the measurement of corruption. The results indicate, by assuming two factors affecting corruption (size of underground economy and real wages), the corruption fuzzy index for Iran had been 0.7 during 1964-1969, but it has the decreasing trend for the period of study. Between 1974-1979 and also after 1994, the index shows the increasing trend. After the Islamic revolution and during the Iran-Iraq War, the fuzzy index remained relatively unchanged. After the war, the overall trend of index shows a tendency to increase. JEL Classification: D73, E27
