Global value chains (GVCs) have grown rapidly over the past several decades. Over the same period, the aggregate value of current account imbalances has risen substantially. This paper looks at whether these developments are related. While there is a sizable literature that has documented the...

In recent years the US current account deficit has grown to the point that most observers consider its level to be already unsustainable. Yet it seems set to continue to increase in the foreseeable future, with net foreign debt likely to surge. This paper describes the present deficit from three...

The scale of unrecorded trade across the border between Nigeria, the region’s biggest economy and market, and its francophone neighbours is particularly high. Despite providing economic incentives, informal trade entails costs, complications and sometimes risks. This paper explores how policy...

This paper uses network analysis to map and characterise live animal trade in West Africa. Building on a database of 42 251 animal movements collected by the Permanent Inter-State Committee for Drought Control in the Sahel (CILSS) from 2013-17, it describes the structure of regional livestock...

We argue for a new approach to examining the relationship between tariffs and growth. We demonstrate that more can be learned from time series analyses of the experience of individual countries rather than the usual panel data approach, which imposes a causal relation and presents an average...

This note studies exchange rate pass-through to the prices of domestically produced goods, exploring the firm-level pricing survey conducted by the Bank of Korea. The data reveal the imported inputs channel of, as well as nonlinear and asymmetric, exchange rate-pass-through.

This paper studies the dynamics of international trade flows at business cycle frequencies. We show that introducing dynamic considerations into an otherwise standard model of trade can account for several puzzling features of trade flows at business cycle frequencies. Our insight is that...

We investigate whether global value chains have increased the sensitivity of Chinese trade to foreign income shocks. This may occur through either composition or supply chain effects. We find evidence for the former, but not the latter.

I provide novel evidence for the impact of trade policy uncertainty on exporters. In a dynamic, heterogeneous firms model, trade policy uncertainty will delay the entry of exporters into new markets and make them less responsive to applied tariff reductions. Policy instruments that reduce or...
