 note = {This article deals with 'the informal sector' which is one of the most important issues in modern development economics. In fact, there are some rooms for controversy concerning the definition of this sector. In first section, we introduce one simple definition by ILO (International Labor Organization) Mission [1972]. According to it, informal activites are characterised by 1.ease of entry; 2.reliance on indigenous resources; 3.family ownership of enterprises; 4.small scale of poeration; 5.labour-intensive and adapted technology; 6.skills acquired outside the formal school system; and 7.unregulated and competitive markets. There specific characteristics are in a striking contrast to those of the formal sector. However, we are not satisfired with referring to the difference between the two sectors, but should be interested in making sure of the concept of informality more comprehensively and more disciplinarily. Hence, we reconfirm it from various dimensions and compare it with the reality in the light of available statistics, especially those of Latin American countries, in section II. Facts of Urbanization and informalization in many countries are made clear there. In a sense these phenomena may be compared to dualistic structure which can be seen in many developing countries (LDC's). But in developmental context, so far it has been considered as one of the distinguished problems involved in LDCs' developing process. That is an appendix of migration of labourers there. Therefore it should be inquired from the point of view of subtlety or true economic theory. In the line of dualism, Todaro constructed his own model and considered interrelation between rural-urban sectors, and found out that the unemployed had been created in urban sector in the process of urbanization in most of LDC's . He contrived the notion of expected wage as an economic motive for labourers to move from rural sector to urban one. But, it is a fact that he neglected existence of informal sector in the process of urbanization. In spite of this fact, it is important for us to recognize that he gave one step of progress to this discipline. In section III, therefore, we deal with his model expansively, and incorporate informal sector in it. In that sense, his model is still significant. We conclude that Todaro-model is still useful in considering informal sector within a dualistic economy in spite of its imperfection, and that the increase of employment of fromal sector has complicated effects, following O.Stark(s terms, a complex of competitive and complementary effects.},
