UK Trade in the Wake of Brexit

Thomas Sampson (London School of Economics and Political Science)

Thomas Sampson is an Associate Professor of economics at the London School of Economics. His research studies the impact of globalisation on workers, firms and productivity. Thomas is also an academic adviser to the Bank of England and an associate at the Centre for Economic Performance where he has worked extensively on the economic consequences of Brexit. Prior to joining the London School of Economics, Thomas worked as an Overseas Development Institute Fellow at the Bank of Papua New Guinea and obtained a PhD in economics from Harvard University.

This paper studies the impact of Brexit on the UK’s trade with the EU relative to its trade with the rest of the world. We find no evidence that uncertainty and anticipation effects led to a significant decline in relative UK trade with the EU during the period after the UK voted for Brexit in 2016 and before the change in policy was implemented under the new Trade and Cooperation Agreement (TCA) in 2021. However, the UK’s departure from the EU’s single market and customs union at the start of 2021 caused a major shock to UK-EU trade. We estimate that the new TCA trade relationship led to a sudden and persistent 25% fall in relative UK imports from the EU. In contrast, we find a smaller and only temporary decline in relative UK exports to the EU, but nevertheless a large and sustained drop in the extensive margin of exports, driven by the exit of low-value relationships. The timing and asymmetry of Brexit effects on UK imports and exports is puzzling and provides evidence of important differences in adjustment to integration and disintegration shocks.


The Welfare Effects of Leaving the EU

Nicolò Tamberi (UK Trade Policy Observatory, University of Sussex)

Nicolò Tamberi is a Research Officer in Economics at the UK Trade Policy Observatory at the University of Sussex, as well as a PhD student in Economics at the University of Sussex. His interests are international trade and political economy and he holds a BSc in Economics from Universita’ Politecnica delle Marche and an MSc in International Economics from the University of Sussex. He has worked as a consultant on trade policy issues for different government departments.

This paper evaluates the welfare effects of leaving the EU. This is done in three steps. First, I estimate trade barriers imposed by the TCA looking at changes in UK-EU trade in goods and services. Second, I use the 2021 change in UK’s MFN tariff to estimate the trade elasticity accounting for the endogeneity of tariff changes. Finally, I use the estimated trade barriers and elasticities in a modern general equilibrium trade model with input-output linkages. Results point to welfare changes of -1% for the UK and -0.1% for the EU in the first year of the TCA. The cut in UK’s MFN tariff softened the loss by 0.1pp for the UK.

From unilateral carbon border measures to plurilateral arrangements: the road towards climate clubs

Giulia Claudia Leonelli (Birkbeck, University of London)

Dr Giulia Claudia Leonelli is Lecturer in Law at Birkbeck College, University of London, and Research Fellow at the Transnational Law Institute, King’s College London. She was awarded a PhD in Law by King’s College London, where she was also Postdoctoral Fellow.  Her current research projects lie at the intersection of trade and environmental law, with a particular focus on climate change law aspects. Her research has been published in leading academic journals. Dr Leonelli has contributed written evidence to inquiries of the House of Commons International Trade Committee and the House of Lords International Agreements Committee and is a Member of the TaPP Network. 

Unilateral carbon border measures have been in the spotlight since the 2021 publication of the European Commission’s proposal for a carbon border adjustment mechanism (CBAM). In the meantime, discussions on the establishment of plurilateral climate clubs have developed in the background. This presentation critically assesses different regulatory models for plurilateral climate club arrangements, focusing on their respective advantages and shortcomings. It advocates adherence to top-down or bottom-up models involving recourse to product standards and bans.

The European Union (EU) recently declared its intention to implement a carbon border adjustment mechanism (CBAM) to address carbon leakage and competitiveness concerns associated with elevated climate ambitions in its Green Deal. Current literature points to uncertainties regarding the CBAM’s effectiveness and compatibility with international trade rules. This study numerically evaluates how alternative EU CBAM designs under various international reactions affect global and regional GHG emissions, outputs and trade flows.

Our modeling results confirm substantial carbon leakages and reductions in outputs in the EU’s emissions-intensive trade-exposed (EITE) sectors when implementing the Green Deal. We show that the design of the CBAM matters: while a “non-discriminatory” CBAM based on the EU’s own scope 1 emission intensities fails to effectively reduce leakages, an ‘aggressive’ CBAM based on exporters’ scope 1 & 2 emission intensities can achieve such goal (albeit with potentially high implementation cost). International retaliations by non-EU countries can only partially offset the EU’s gains from the ‘aggressive’ CBAM, while their cooperation can result in smaller losses to the EU EITE sectors and lower leakages. Finally, the CBAM cannot change within-EU imbalances in the EITE sectors, as several EU members lose EITE outputs consistently in all scenarios with and without retaliations.

Of Bytes and Trade: quantifying the impact of digitalisation on trade

Javier López-González (Organisation for Economic Cooperation and Development)

Dr. Javier López-González is a Senior Economist at the Trade and Agriculture Directorate of the OECD where he leads the work on digital trade. His recent work includes: developing frameworks for the analysis and measurement of digital trade, exploring what market openness means in the 21st century; investigating regulatory approaches to cross-border data flows; and identifying potential economic costs and benefits of digital trade. He has previously worked on the drivers and implications of participation in global value chains. Javier holds a PhD in Economics from the University of Sussex. 

Although it is widely acknowledged that digital connectivity and digital trade policies matter for trade, their quantitative importance has been difficult to capture. This paper provides new evidence on the nature and evolution of digital trade and highlights how digital connectivity and digital trade policies affect trade and trade costs. Using proxy measures, the paper shows that digital trade has been growing and could represent as much as 22% of global trade in 2018. It also suggests that the geography of digital trade is shifting away from OECD countries and towards emerging economies, and that digital trade is becoming more services oriented. The econometric analysis shows that a 10% change in bilateral digital connectivity leads to an increase in trade of 3%, impact which has been rising in time. The paper also shows that digital trade policy measures affecting infrastructure and connectivity, which include conditions on the flow of data and data localisation measures, are those that most negatively impact trade flows. Overall, the paper underscores the importance of engaging in digital trade policy discussions, whether domestically, in RTAs or at the WTO. 


The UK’s joining the CPTPP and digital trade policy -Towards accommodations and conflicts?

The UK is facing regulatory constraints on digital trade to join the CPTPP since the UK is a country with different regulatory standards based on European societal norms and values. It is true that the UK has already departed from the EU style digital trade governance by concluding the innovation and market efficiency focused digital trade provisions with some CPTPP members including Australia, New Zealand, Japan and Singapore. And the CPTPP digital trade provisions are narrower and shallower thanthese ambitious agreements. However, the CPTPP is different. There are huge data governance gaps between the UK and the CPTPP members and the ethical, trust, and human rightsconsiderations are much weaker than those in the UK. Accommodation to some CPTPP digital provisions, such as data privacy and strict public policy exceptions in relation with free cross-border data flow, may intensify societal concerns in the UK and may even endanger the EU’s adequacy decision to the UK.

Global data sharing can help address what scholars call wicked problems—problems so complex that they require innovative, cost effective and global mitigating strategies. Many factors impede global data sharing for public good purposes; this analysis focuses on two. First, policymakers generally don’t think about data as a global public good; they view data as a commercial asset that they should nurture and control. While they may understand that data can serve the public interest, they are more concerned with using data to serve their country’s economic interest. Secondly, many leaders of civil society and business see the data they have collected as proprietary data. So far many leaders of private entities with troves of data are not convinced that their organization will benefit from such sharing. At the same time, companies voluntarily share some data for social good purposes. However, data cannot meet its public good purpose if data is not shared among societal entities. Moreover, if data as a sovereign asset, policymakers are unlikely to encourage data sharing across borders oriented towards addressing shared problems. Consequently, society will be less able to use data as both a commercial asset and as a resource to enhance human welfare. This paper discusses why the world has made so little progress encouraging a vision of data as a global public good. As UNCTAD noted, data generated in one country can also provide social value in other countries, which would call for sharing of data at the international level through a set of shared and accountable rules (UNCTAD: 2021). Moreover, the world is drowning in data, yet much of that data remains hidden and underutilized. But guilt is a great motivator. The author suggests a new agency, the Wicked Problems Agency, to act as a counterweight to that opacity and to create a demand and a market for data sharing in the public good.

Supporting sustainability in agri-food production in Vietnam: FTAs, regulation or voluntary standards?

Camille Vallier (UK Trade Policy Observatory, University of Sussex and University of Geneva)

Camille Vallier is a Research Fellow at the University of Sussex. She works on the Horizon2020 research project “Trade4SD”, which studies the impacts of EU’s FTAs’ sustainability provisions on agri-food production. She is also a lecturer in Environmental Law at the University of Geneva (Switzerland). She holds a PhD in law from the University of Geneva, an LL.M from the University of London (SOAS), and a Bachelor and Master of law from the University of Geneva. Her PhD thesis, entitled “Seeds and Public Law: Food, Health and the Environment” was defended with summa cum laude in January 2021.

This presentation will compare the influence of EU FTA environment chapters, EU regulation and voluntary standards in influencing sustainability of agri-food production in exporting countries. Based on research undertaken in the coffee sector of Vietnam, we will argue that FTA environment chapters have had little influence when they are not combined with other legal tools or instruments.

Preferential Trade Agreements (PTAs) have increasingly been used to promote environmental protection and climate issues, as denoted by the increasing number and variety of specific environmental provisions included in the agreements. The effectiveness of these commitments in helping countries to make progress towards environmental targets is still unclear, however. In this paper we empirically estimate the effect of specific environmental provisions in PTAs on selected environmental targets as defined in the Sustainable Development Goals. We combine a detailed dataset on environmental norms in PTAs with data on a broad range of environmental outcomes, and find heterogenous effects across the various outcomes. Provisions on the use of renewable energy and the reduction of greenhouse gas emissions appear to be particularly effective.
