Abstract
This paper studies how voting to leave the European Union affected living standards in the United Kingdom. Using heterogeneity in exposure to import costs across product groups, we analyze how the depreciation of sterling caused by the referendum affected consumer prices. We find the Brexit depreciation led to higher inflation in product groups with greater import shares in consumer expenditure. Our results are consistent with complete pass-through of the cost of imports to consumer prices and imply aggregate exchange rate pass-through of 0.29. We estimate the Brexit depreciation increased consumer prices by 2.9 percent, costing the average household £870 per year.
