Trade costs, trade performance and global value chains

Abstract : The economic literature attributes a critical role to trade costs in explaining international trade flows. The expansion oftrade over the last few decades is regularly associated with the sharp drop in trade barriers between countries around theworld over this period. The purpose of this thesis is to re-examine the real importance of these costs on international tradethrough different methodologies. In the first chapter, we examine the economic performance of Manaus in the Brazilianstate of Amazonas, to determine whether the significant trade costs it faces substantially affect its export performancenotably towards other Brazilian states. The second chapter examines the export performance of African countries, whichalso face high levels of trade costs, in the light of the most recent advances in the literature on international trade, but alsoby using value-added exports instead of gross exports as the variable of interest. The third chapter examines the impactof international fragmentation in the welfare gains of trade, but also the role played by trade costs in the participation inglobal value chains. These three chapters suggest that a high level of trade costs is not necessarily opposed to exportperformance, but that low trade costs are necessary to locate in the downstream of the production process, and thusbenefit from higher welfare gains of trade.
