Dışsallık ve Kayıtdışı Ekonomi Kavramına İlişkin Bir Değerlendirme

In this tiny study, we aimed at making some distinction among different concepts such as "unrecorded," "twillight," "underground," or "unofficial" economy. In making this analysis, we used a matrix of meanings and conditions of informal economy. We suggested some weights for each concept by using asterisks.In the second part, it is tried to make a distinction between the concepts of "externality" and the"informal economy." We pointed and stressed an asimmetrical relation between these concepts.
