This study presents an overview of current research on the relationship between trade globalization and informal jobs in developing economies. Based on existing academic literature and complemented by new research by the ILO and WTO, this report discusses the impact of trade reforms on different dimensions of informal employment. Various transmission mechanisms are discussed, setting results from country studies against international comparisons. The volume analyses the policies necessary for countries with large informal economies to take advantage of trade reforms and maximize the benefits from international trade. It discusses the obstacles created by high informality rates to translating trade openness into sustainably higher long-term growth rates. The book focuses on the connections between trade, labour and social policies, creating conditions for countries to successfully integrate into the world economy. It will be of interest to all those who are involved in this debate, in particular trade specialists, economists, policy-makers, employers and trade unions.
