Given the commonality of employment in the informal economy, this paper moves beyond classifying nations by the composition of their formal economies and instead classifies countries by the extent and nature of employment in the informal economy. Analysing ILO data on the size and character of employment in the informal economy in 36 developing economies, the outcome is to reveal a significant correlation between cross-national variations in the degree and intensity of informalisation and cross-national variations in GNP per capita, corruption, poverty, taxation and social contribution levels. The paper concludes by discussing the implications for theory and policy.Keywords: informal sector; shadow economy; developing economies; economic development.
IntroductionUntil now, classificatory schemas of economies have differentiated countries by the character of their formal economic systems, such as by their levels of Gross Domestic Product (GDP) or Gross National Income (GNI) per capita (World Bank, 2013), whether they are control, market or mixed economies (Arnold, 1996;Rohlf, 1998), or liberal or coordinated varieties of capitalism (Hall and Soskice, 2001). This would be appropriate if the majority of employment globally was in the formal economy. However, this is not the case (Jütting and Laiglesia, 2009;ILO, 2012ILO, , 2013 Williams and Lansky, 2013). Consequently, the aim of this paper is to develop a classification of economies according to the commonality and character of employment in the informal economy. The importance of doing this is that it not only brings to the fore the persistence of employment in the informal economy across the world but also draws attention away from the formal labour market in which only a minority of jobs globally are located and towards what is to be done about employment in the informal economy in which the majority of jobs are found.To do this, the first section will briefly review how employment in the informal economy is defined, provide a typology that classifies economies according to the extent and nature of employment in the informal economy and review the competing explanations for the cross-national variations in the prevalence and character of employment in the informal economy. In the second section, and to begin to classify economies and evaluate critically the competing explanations for the cross-national variations, a data set is then introduced, namely the ILO dataset of country surveys on the informal sector and informal employment, which contains data on the level and nature of employment in the informal economy in 36 developing countries. The third section then reports the descriptive findings on the crossnational variations in the degree and intensity of informalisation followed in the fourth section by a preliminary evaluation of the competing explanations for these cross-national variations. The fifth and final section then concludes by summarising the findings and discussing their theoretical and policy implications.
