Professor Lockwood has collected data for a major project at the heart of the agenda of the CSGR: how we might measure economic aspects of globalisation? He plans to study trade flows, financial flows (FDI, equity investment, bank lending) and "people flows" i.e. international migration. A key question is whether economic integration should be measured by policies toward flows (tariffs, exchange rate and migration controls, etc) or by the flows themselves. Preliminary work shows that these two measures are not well-correlated, at least for international trade. The data collection has involved buying data from the World Bank, OECD, IMF, and obtaining other non-published data from leading researchers in the field, such as Geoffrey Garrett at Yale.
