I guess my questions for future research would be: Do we see migration differences across the skill/salary visa-threshold changes? Would the NHS not have plugged the nurse gap in the same way if not for new visa rules? How easier did it get for a UK employer to hire a non-EU migrant after 2021?

COVID impacted comparator countries, but they didn't get the Brexit x COVID mass outflow. I don't doubt the overal Brexit counterfactual numbers. I'm just not sure about the contribution of visa rules vs. outflow-generated demand factors.

Great stuff! I'm wondering how much of the non-EU increase is due to increased employer demand after COVID, rather than to "new rules". When COVID happened after Brexit, many migrants just went back home and never came back. Employers needed workers for the rebound and mostly non-EU applied.

Immigration was central both to the 2016 Brexit referendum campaign and to the political narratives that followed it. Yet the trajectory of migration to the UK since the referendum bears little resemblance to the expectations — or promises — articulated at the time. This paper provides an overview and interpretation of developments since 2016, focusing on three interrelated themes. First, it describes trends in migration flows and stocks, highlighting the sharp fall in EU migration, the compensating increase in non-EU migration, and the role of both policy and economic developments in driving these trends.  Second, it examines the economic and labour market impacts of these changes over 201625. Third, it analyses the post-Brexit policy framework and, in particular, the Labour government’s approach since 2024. The paper concludes by reflecting on the implications for future UK migration policy and for the wider political economy of Brexit.

How new export opportunities created good jobs in Vietnam Bilateral trade agreements create opportunities beyond signatories. The US-Vietnam trade agreement led to large, persistent increases in formal manufacturing employment in Vietnam through the entry and expansion of multinationals from East Asia.

Africa’s offshore ties to Asia are growing, but their consequences… The Oxford Martin School at the University of Oxford brings together the best minds from different fields to tackle the most pressing issues of the 21st…

🌟New paper by Ricardo Soares de Oliveira (@oxmartinschool.bsky.social African Governance Programme) finds that African offshore finance is increasingly routed through Asian financial centres.

The figure shows the ratio of cross-border (across EU countries or US states) to domestic sales for the different datasets in the year 2017 in manufacturing. The level of cross-border relative to domestic trade is higher in the US than in the EU.

European firms tend to be smaller and less productive than US firms. Qualitative and survey-based evidence suggests that one key reason is the remaining barriers fragmenting the EU’s single market. This column argues that gravity-based trade estimates can help quantify the problem but are sensitive to the data used. Intra-EU trade barriers are estimated to be between two to three times as large as between US states, with simulations suggesting that fully closing the gap with intra-US trade costs could raise EU productivity by nearly 6%.

Figure shows the import-weighted average of product-level tariff reductions for countries involved in the economic integration scenario.

While recent analysis has focused on direct impacts of US tariffs and potential retaliation, major US trading partners have intensified trade negotiations with each other, including the recently completed EU–Mercosur and EU–India deals. Using a quantitative trade model, this column shows that deep integration – involving non-tariff barrier reductions – can offset welfare losses from US tariffs and generate net gains. Paradoxically, US tariffs may ease political economy constraints by strengthening incentives for export-oriented industries to lobby for deeper integration elsewhere.
