In recent years, globalisation and trade openings have become increasingly contentious. This book aims to fill a gap in the market by guiding the users through the main sources of data and the most useful empirical tools for trade and trade policy analysis in an applied, real-world context. This approach builds on the comparative advantage of the authoring organisations - the WTO and UNCTAD - both of which have a strong policy focus. It quantifies trade flows and trade policies, presents the gravity models, and covers a number of simulation methodologies to predict the effects of trade and trade-related policies on trade flows, welfare and the distribution of income.
