In this paper we employ an extension of the World Input-Output Database (WIOD) with regional detail for EU countries to study the degree to which EU regions and countries are exposed to negative trade-related consequences of Brexit. We develop an index of this exposure, which incorporates all effects due to geographically fragmented production processes within the UK, the EU and beyond. Our findings demonstrate that UK regions are far more exposed than regions in other countries. Only regions in the Republic of Ireland face exposure levels similar to some UK regions, while the next most affected regions are in Germany, The Netherlands, Belgium and France. This imbalance may influence the outcomes of the negotiations between the UK and the EU.

| INTRODUCTIONSince the UK decided in 2016 by referendum to leave the European Union there has been a large and growing body of material explaining the reasons for the decision in both the academic arena as well as in the popular press. In contrast, there has been much less post-referendum material emerging regarding the likely long-term impacts of this decision, and there are probably two main reasons for this. First, there were various forecasts produced by different organizations prior the

Although there is now emerging evidence of the effects of a devalued Sterling on UK inflation and living standards (Financial Times, 2017a), as well as a fragile trade balance even under currency depreciation, the fact that no UK recession has so far materialized (The Economist, 2017) probably makes many forecasters rather loathe to speculate any further.Second, and more importantly, Brexit has not yet actually happened, and it is very difficult to speculate in detail about the likely long-run impacts of Brexit until the specific outlines of the new UK-EU trading relationships become clear.What we aim to analyse here is the exposure of regions in the UK and the EU to Brexit, via an analysis of the nature and scale of their trade linkages. Other potential advantages and disadvantages, for example as a consequence of the relocation of UK subsidiaries of multinational firms or the redistribution of subsidies to regions are not considered. 1 In this study, we intend to quantify the shares of regional and national GDP and labour income (in the UK and the EU) that are at risk due to Brexit. The extent to which these risks will actually materialize, for example via tariffs and non-tariff barriers to trade between the EU and the UK, will depend on the final agreements reached (if...
