The MIMIC approach used in this paper explicitly considers various causes, as well as several effects of the informal economy. The model exploits the associations between observables causes and observable effects of the unobserved informal economy to estimate the size of the informal economy itself. 4 The model can be described as: y = λ IE + ε ( 1 ) IE
