An explosion of different preferential rules of origin (PROO) has accompanied the spread of preferential trade agreements (PTAs) around the world. Complying with PROO requirements entail costs for producers, exporters, and customs officials. Observers, firms, customs officials, and policymakers...

This paper contributes to the debate on the existence of pollution haven effects by systematically measuring the pollution content of trade (measured by the polluction content of imports (PCI)) and decomposing it into three components: a 'deep' (i.e. unrelated to the environmental debate)...

Combining unique data bases on emissions with sectoral output and employment data, we study the sources of the fall in world-wide SO2 emissions and estimate the impact of trade on emissions. Contrarily to concerns raised by environmentalists, an emission-decomposition exercise shows that scale...

Rules of origin are critical components of preferential trade agreements designed to stop products coming in under insufficient transformation or through the partner that applies the lowest tariff. But in practice, these rules are often needlessly complex, undoing the benefits of market access...

The main objective of the African Continental Free Trade Area is to eliminate trade barriers and boost intra-Africa trade. This column argues that implementing the Trade Facilitation Agreement's provisions would be a powerful complement to the free trade area's tariff-reduction agenda. A...

Using the influence-driven approach to endogenous trade-policy determination, we show how a free-trade agreement (FTA) with rules of origin can work as a device to compensate losers from trade liberalization. The FTA constructed in this paper is characterized by external tariff structures that...

Political motives, geography, and the uneven distribution of gains trumped the traditional efficiency gains across Africa's Regional Economic Communities (RECs). The small, sparsely populated, fragmented, and often isolated economies across Africa make a compelling case for these economies to...

This paper appraises the likely effects of the Economic Partnership Agreement (EPA) between the East African Community (EAC) and the European Union (EU). Customs data are used to estimate the revenue and welfare effects of an EPA with and without an exception list. Revenue and welfare effects...
