This study focuses on the economic shocks that a ‘no deal’ Brexit would entail across the constituencies of Hampshire and Sussex. We take estimates of the effects of a ‘no deal’ Brexit on output and employment in different sectors of the UK economy and using the composition of employment in each constituency, estimate how each constituency will be affected. The novel feature of our analysis is that we allow for commuting and so convert the Brexit shock from referring to workers in a constituency to referring to residents in the constituency. With the South East region the most heavily engaged in cross-border trade, after allowing for the fact that people often live and work in different places, we estimate that the shock to residents of Hampshire and Sussex could be equivalent to the loss of about 43,000 jobs. Given that Brexit decisions will ultimately be taken on the floor of the House of Commons, this Briefing Paper provides a base from which Hampshire and Sussex MPs can start to assess the impact of Brexit on their constituents.
