Generalised System of Preferences programmes, a form of nonreciprocal tariff cuts, have proliferated since the 1970s. Using a well-documented dataset of international trade agreements, this column studies the effectiveness of the system on beneficiaries’ aggregate exports. It finds that nonreciprocal tariff preferences can have a strong positive effect on the exports of least-developed countries, provided that they are WTO members. Conversely, other developing economies enjoying nonreciprocal preferences are able to increase exports only if they are not WTO members.

The economic effects of foreign direct investment are generally expected to be positive for the host economy. However, this is usually conditional on certain thresholds of development being met, for instance in terms of human capital or institutional quality. This column argues that the economic impact of foreign direct investment is less ‘conditional’ than commonly thought, perhaps because below the thresholds, the difference between private and social returns is substantial, while above them it is smaller.

The members of the Eurozone are diverse in terms of their institutional quality. This column outlines the redistributive effects created by the rigid structure of a monetary union next to its direct effects on monetary credibility, and highlights the general equilibrium benefits that core countries draw from it and the cost paid by the productive sector in ‘weaker’ countries. Europe faces a clear challenge, but the success of the transition to the banking union suggests that collective efforts towards institutional evolution can succeed.

To mitigate the risks of international trade for firms, banks offer trade finance products – specifically, letters of credit and documentary collections. This column exploits new data from the SWIFT Institute to establish key facts on the use of these instruments in world trade. Letters of credit (documentary collections) cover 12.5% (1.7%) of world trade, or $2.3 trillion ($310 billion).
